Frobese, Dirk-Hans; Pape, Harald [Physikalisch-Technische Bundesanstalt, Braunschweig (Germany)

2011-08-15

This work was aimed at determining possible causes of overpressure damages on road tankers. In cooperation with the manufacturers of road tankers, the equipment of road tankers usually used today was, therefore, discussed and possible error sources determined. In measurements performed at two filling stations, real pressure, temperature and volume flow ratios for the loading of a road tanker were recorded. Parallel to it, tests in a cold chamber were carried out to determine the possibility and the general conditions of an icing of the tilting valve and the flame arrester. With these results, scenarios have been worked out which can explain known overpressure damaging events. On the basis of a risk assessment, measures are described how such overpressure damages on road tankers can in future be avoided. (orig.)

Biological and Archaeological Analysis of Deepwater Shipwrecks in the Gulf of Mexico: Studying the Artificial Reef Effect of Six World War II Shipwrecks

Science.gov (United States)

Church, R. A.; Irion, J. B.; Schroeder, W. W.; Warren, D. J.

2006-12-01

In the summer of 2004 researchers from across the United States and Canada partnered together to investigate biological and archaeological questions relating to six World War II era shipwrecks discovered in the Gulf of Mexico. The science team included microbiologists, marine vertebrate and invertebrate zoologists, a molecular biologist, an oceanographer, marine archaeologists, remotely operated vehicle (ROV) technicians, and a professional marine survey crew. The United States Department of the Interior, Minerals Management Service, and the NOAA Office of Ocean Exploration sponsored this multidisciplinary project under the auspices of the National Oceanographic Partnership Program. The organizational involvement included six universities, two non-profit organizations, three commercial companies, and three U. S. federal agencies. The depth of the shipwrecks ranged from 87 to 1,964 meters. All six shipwrecks were war casualties, found during the past two decades on oil and gas surveys. These wrecks serve as artificial reefs sunk on well- documented dates, thereby offering biologists a unique opportunity to study the "artificial reef effect" of man- made structures in deep water. Taken together, these sites are an underwater battlefield, and a vital historical resource documenting a little-studied area in a crucial period of world history. They preserve information vital to scholarly and popular understanding of the war's impact in the Gulf of Mexico, on the American home front, and the global conflict. This paper will discuss the field methodology and touch on many of the scientific and technical aspects, and findings of the project.

Double hull oil tankers - how effective are they?

International Nuclear Information System (INIS)

Keith, V.F.

1993-01-01

The groundings of the Exxon Valdez on Bligh Reef in Prince William Sound, spilling more than 10 million gallons of Alaska North Slope crude, and the American Trader off Huntington Beach, spilling almost 400,000 gallons of Alaska North Slope crude, suggest that the construction of oil tankers be re-examined with respect to a design which could reduce both the number and magnitude of oil spills. This paper discusses state-of-the-art tanker technology with respect to spill prevention, effectiveness, and cost. The design features include double hulls, centralized bunker tankers, vacuum-retaining valves, cargo control systems, auxiliary thrusters, electronic charting, and the retransmission of the ship's position. Double hulls provide the highest probability of surviving damage, either from a collision or grounding, with no loss of cargo. Use of double hulls can reduce oil spill incidence by 90 percent in grounding situations and by 75 percent in collisions. The oil spill from the AmericanTrader could have been completely avoided by double hull construction. The arrangement provides spaces below the cargo tanks and on the vessel's sides solely for the carriage of ballast water when the tanker is in ballast condition. These tanks are empty when the tanker is loaded and then also act as the first line of defense in the event of structural damage to the cargo tanks. Tanker design is integrated with port safety measures, including vessel monitoring systems, in this total spill prevention analysis. All aspects of the tanker transportation system are considered

Proses Individuasi Carl Gustav Jung pada Tokoh Erika Kohut dalam Novel Sang Guru Piano Karya Elfriede Jelinek

2007-12-01

Full Text Available A personality structure that appears in Erika is similar to one of an important part of Carl Gustav Jung psychology. Jung states that personality is a psiko that covers consciousness and unconsciousness. This psiko will develop to be a stable unity. If every system develops in every individual absolutely, so a health and integrated personality will be achieved. That process in Jung is known as a self­ individualized process. The aim of individualism is a self­achievement. Individual is not only as a psiko centre but also as a representation of the whole individual that unites consciousness and unconsciousness. It is like the character "Erika Kohut" in the novel "Sang Guru Piano".

Selecting Tanker Steaming Speeds under Uncertainty: A Rule-Based Bayesian Reasoning Approach

Directory of Open Access Journals (Sweden)

N.S.F. Abdul Rahman

2015-06-01

Full Text Available In the tanker industry, there are a lot of uncertain conditions that tanker companies have to deal with. For example, the global financial crisis and economic recession, the increase of bunker fuel prices and global climate change. Such conditions have forced tanker companies to change tankers speed from full speed to slow speed, extra slow speed and super slow speed. Due to such conditions, the objective of this paper is to present a methodology for determining vessel speeds of tankers that minimize the cost of the vessels under such conditions. The four levels of vessel speed in the tanker industry will be investigated and will incorporate a number of uncertain conditions. This will be done by developing a scientific model using a rule-based Bayesian reasoning method. The proposed model has produced 96 rules that can be used as guidance in the decision making process. Such results help tanker companies to determine the appropriate vessel speed to be used in a dynamic operational environmental.

Target definition for shipwreck hunting

Directory of Open Access Journals (Sweden)

Kim Paul Kirsner

2015-10-01

Full Text Available The research described in the present article was implemented to define the locations of two World War II shipwrecks, the German raider Kormoran, and the Australian light cruiser HMAS Sydney. The paper describes the long and complex trail that led through inefficient oceanographic prediction to ambiguous historical prediction involving a single report and on to precise cognitive prediction based on nine reports from more than 70 survivors, a process that yielded a single target position or ‘mean’ just 2.7 NM (nautical miles from the wreck of Kormoran. Prediction for the position of the wreck of Sydney opened with wishful thinking that she had somehow reached the coast more than 100 NM away when cognitive analysis of the survivor’s reports actually provided the basis for accurate prediction in a position near to the wreck of Kormoran. In the account provided below, the focus on cognitive procedures emerged from, first, a review of a sample of the shipwreck hunts, and, second, growing awareness of the extraordinarily rich database available for this search, and the extent to which it was open to cognitive analysis. This review touches on both the trans-disciplinary and the cognitive or intra-disciplinary issues that so challenged the political entities responsible for supervising of the search for the wrecks of Kormoran and Sydney. One of the theoretical questions that emerged from these debate concerns the model of expertise advanced by Collins (2013. The decomposability of alleged forms of expertise is revealed as a fundamental problem for research projects that might or might not benefit from trans-disciplinary research. Where expertise can be decomposed for operational purposes, the traditional dividing lines between experts and novices, and fools for that matter, are much harder to discern, and require advanced and scientifically informed review.

Metallurgical characterization of brass objects from the Akko 1 shipwreck, Israel

International Nuclear Information System (INIS)

Ashkenazi, D.; Cvikel, D.; Stern, A.; Klein, S.; Kahanov, Y.

2014-01-01

The Akko 1 shipwreck was a small Egyptian armed vessel or auxiliary naval brig built in the eastern Mediterranean at the beginning of the 19th century. During the underwater excavations, about 230 brass hook-and-eye closures were found, mainly in the bow area. In addition, 158 brass cases were found, mainly between midships and the aft extremity of the shipwreck. Metallurgical non-destructive and destructive characterizations of selected items were performed, including radiographic testing, XRF, lead isotope analysis, optical microscopy, SEM–EDS and microhardness tests. The hook-and-eye closures and the cases were both found to be made of binary copper–zinc alloy (about 30 wt.% zinc). While the brass cases were made from rolled sheets, hand-made using simple tools, and joined by tin–lead soldering material, the brass hook-and-eye closures were hand-made from drawn brass wire, and manufactured from commercial drawn brass bars by a cold-working process. The lead isotope analyses suggest different provenances of the raw materials used for making the brass objects, thus the different origins of the ores may hint that the brass wire and sheet were imported to the workshops in which the objects were manufactured. - Highlights: • Brass cases and hook-and-eye closures were retrieved from the Akko 1 shipwreck. • Both types of objects were made of binary copper–zinc alloy (about 30 wt.% zinc). • The cases were hand-made from rolled sheets and joined by tin–lead soldering. • Hook-and-eye closures were made from drawn brass wire manufactured by cold-working. • Lead isotope analyses suggest that the origins of the raw material were diverse

Determinants of the property damage costs of tanker accidents

International Nuclear Information System (INIS)

Talley, W.K.

1999-01-01

This study investigates determinants of the vessel, oil cargo spillage, and other-property damage costs of tanker accidents. Tobit estimation of a three-equation recursive model suggests that, among types of tanker accidents, fire/explosion accidents incur the largest vessel damage costs, but the smallest oil cargo spillage costs. Alternatively, grounding accidents incur the smallest vessel damage costs, but the largest oil cargo spillage costs, reflecting the difficulty of controlling oil cargo spillage subsequent to such accidents. Also, oil cargo spillage costs are lower for US flag tanker accidents. A dollar of vessel damage cost increases other-property damage cost by 0.06 dollars, whereas a dollar of oil cargo spillage increases this cost by 1.55 dollars

U.S. oil spill law to cause growing tanker problem

International Nuclear Information System (INIS)

Price, R.B.

1991-01-01

This paper reports on tanker owners which face a growing dilemma on the issue of oil spill liability. The U.S. Oil Pollution Act, passed last year in the wake of the March 1989 Exxon Valdez oil spill, was intended to reduce risk of and damage from such accidents. However, in addition to phasing in double hulls on most tankers operating in U.S. waters, the law substantially increases shipowner's liability for spills. And the federal law does not preempt state liability laws, which in most cases amount to unlimited liability for spill cleanup. Rather than face potentially unlimited liability in the event of a spill, tanker owners worldwide are exercising a number of options to shield themselves. Some of those options could increase the potential for oil spills, industry officials warn. The act also threatens to shatter the international alliance among shippers. A report by Drewry Shipping Consultants Ltd., London, says the law could have a devastating effect on operating practices. Tanker owners and operators have voiced the most opposition to the new spill law and the shackles it places on them. Now the industry that insures tankers has spoken up about is increased liability, and it too may launch a boycott

Tanker traffic off Newfoundland worries fishermen

International Nuclear Information System (INIS)

Reid, W.

2002-01-01

Tanker traffic offshore in Placentia Bay, Newfoundland has increased considerably, where approximately 300 tankers show up yearly to load up at the oil refinery located in the nearby village of Come By Chance. On numerous occasions, fishermen busy pulling gear over the gunwales looked up only to be faced with an approaching superstructure just emerging from the fog, leaving barely enough time for the fishermen to get out of the way. Fog does not help the situation, often reducing visibility to less than one kilometre approximately 187 days yearly. Fishermen are reluctant to avoid shipping lanes, as some of the best grounds are located in the vicinity. A few close calls and one accident were briefly described. Requests have been made for the pilots bringing large ships into dock to board farther out at sea to avoid the danger of collision. It was mentioned that another factor could be crew members on some ships unable to speak English. Fishermen are not happy that results from ship inspections are not posted on the Web as is the case in the United States. An environmentalist has also requested that an ocean-going-tug be used for towing tankers in trouble out of the way to prevent an ecological disaster

Aerodynamic Efficiency Analysis on Modified Drag Generator of Tanker-Ship Using Symmetrical Airfoil

Science.gov (United States)

Moranova, Starida; Rahmat Hadiyatul A., S. T.; Indra Permana S., S. T.

2018-04-01

Time reduction of tanker ship spent in the sea should be applied for solving problems occured in oil and gas distribution, such as the unpunctuality of the distribution and oil spilling. The aerodynamic design for some parts that considered as drag generators is presumed to be one of the solution, utilizing our demand of the increasing speed. This paper suggests two examples of the more-aerodynamic design of a part in the tanker that is considered a drag generator, and reports the value of drag generated from the basic and the suggested aerodynamic designs. The new designs are made by adding the NACA airfoil to the cross section of the drag generator. The scenario is assumed with a 39 km/hour speed of tanker, neglecting the hydrodynamic effects occured in the tanker by cutting it at the waterline which separated the drag between air and water. The results of produced drag in each design are calculated by Computational Fluid Dynamic method.

Proteolysis produced within biofilms of bacterial isolates from raw milk tankers.

Teh, Koon Hoong; Flint, Steve; Palmer, Jon; Andrewes, Paul; Bremer, Phil; Lindsay, Denise

2012-06-15

In this study, six bacterial isolates that produced thermo-resistant enzymes isolated from the internal surfaces of raw milk tankers were evaluated for their ability to produce proteolysis within either single culture biofilms or co-culture biofilms. Biofilms were formed in an in vitro model system that simulated the upper internal surface of a raw milk tanker during a typical summer's day of milk collection in New Zealand. The bacterial isolates were further evaluated for their ability to form biofilms at 25, 30 and 37°C. Mutual and competitive effects were observed in some of the co-culture biofilms, with all isolates being able to form biofilms in either single culture or co-culture at the three temperatures. The proteolysis was also evaluated in both biofilms and corresponding planktonic cultures. The proteolysis per cell decreased as the temperature of incubation (20-37°C) increased. Furthermore, mutualistic interactions in terms of proteolysis were observed when cultures were grown as co-culture biofilms. This is the first study to show that proteolytic enzymes can be produced in biofilms on the internal surfaces of raw milk tankers. This has important implications for the cleaning and the temperature control of raw milk transport tankers. Copyright © 2012 Elsevier B.V. All rights reserved.

Assessing the Long-Term Efficacy of Geotextiles in Preserving Archaeological Wooden Shipwrecks in the Marine Environment

Science.gov (United States)

Pournou, Anastasia

2017-09-01

Archaeological wood cannot be found preserved in the marine ecosystem unless it is buried in anoxic or dysoxic sediments. These habitats do not allow the growth and activity of wood degraders, and thus wooden shipwrecks can survive within these environments for centuries. However, due to natural factors or anthropogenic interventions wood can be re-exposed to the oxygenated water column, where it disintegrates rapidly. In such cases, in situ preservation becomes a main priority, as lifting and conservation are not usually feasible. One of the most common in situ preservation methods is the covering of wood with geotextiles. To date however, even though this method has been used worldwide the past decades, its long-term performance and effectiveness hasn't been evaluated. This work presents, for the first time, results on the efficacy of geotextiles used for 12 years on a shipwreck found in the Mediterranean. Fabric performance was evaluated based on wreck timbers condition, its physical, mechanical and hydraulic properties and the ecological and hydrographical profile of the underwater site created, following its application. Obtained results demonstrated that wreck timbers covered with geotextiles did not show signs of attack during the 12 years of in situ preservation. Geotextiles properties were found to be adequately retained when compared with properties of new unused geotextiles. The fabric had entrapped sediment and was colonised by the local flora and fauna, re-establishing anoxic conditions. This work showed that geotextiles can successfully preserve in situ wooden shipwrecks in high biodeterioration risk environments for at least a 10 year period.

Worldwide there are tens of thousands of sunken shipwrecks lying on the coastal seabed. These potentially polluting wrecks (PPW) are estimated to hold 3-25milliont of oil. Other hazardous cargo in PPW includes ordnance, chemicals and radioactive waste. Here, we present and discuss studies on mercury (Hg) and oil pollution in coastal marine sediment caused by two of the >2100 documented PPW in Norwegian marine waters. The German World War II (WWII) submarine (U-864) lies at about 150m below the sea surface, near the Norwegian North Sea island of Fedje. The submarine is estimated to have been carrying 67t of elemental Hg, some of which has leaked on to surrounding sediment. The total Hg concentration in bottom surface sediment within a 200m radius of the wreckage decreases from 100g/kgd.w. at the wreckage hotspot to about 1mg/kgd.w. at 100m from the hotspot. The second wreck is a German WWII cargo ship (Nordvard), that lies at a depth of ca. 30m near the Norwegian harbor of Moss. Oil leakage from Nordvard has contaminated the bottom coastal sediment with polycyclic aromatic hydrocarbons (PAH). The findings from this study provide useful insight to coastal administration authorities involved in assessing and remediating wreck-borne pollution from any of the tens of thousands of sunken shipwrecks.

Safety at sea: oil spills, the tanker business and international regulations

Energy Technology Data Exchange (ETDEWEB)

Golomer, Olivier

1994-02-01

The tanker industry has been assailed in recent years with regulations, inspections, and many, many criticisms. The official objective of these pressures - the preservation of the environment from oil spills and oil contamination - is praiseworthy. However, many of these measures have proved inefficient or have led to ludicrous situations due in large part to them being targeted on crisis situations. Instead of emergency regulations spurred by sporadic disasters, both the tanker industry and protection of the environment need a set of economic instruments relying on a systematic assessment of risks. This paper focuses on these issues in the Very Large Crude Carrier segment of the tanker business. We start with a description of the industry and the actors in place, and then review the measures and policies adopted so far and their influence on the industry, especially in relation to freight rates. By analogy with other industries, a comprehensive approach to environmental hazards is then proposed. (Author)

There are more than 2,000 documented shipwrecks in the Gulf of Mexico. Historic shipwrecks are invaluable cultural resources, but also serve as artificial reefs, enhancing biodiversity in the deep sea. Oil and gas-related activities have the potential to impact shipwreck sites. An estimated 30% of the oil from the Deepwater Horizon spill was deposited in the deep-sea, in areas that contain shipwrecks. We conducted field and laboratory experiments to determine if crude oil, dispersed oil, and/or dispersant affect the community composition, metabolic function, and/or corrosion potential of microorganisms inhabiting shipwrecks. Platforms containing carbon steel coupons (CSC) (n = 34 per platform) were placed at impacted and non-impacted shipwrecks or into four experimental microcosm tanks. After a 2-week acclimation period, tanks were treated with crude oil and/or dispersant or received no treatment. CSC and seawater (SW) samples for bacterial genetic analysis were collected bi-weekly (at 16 wks for field samples). Proteobacteria dominated field and lab CSC bacterial communities (77-97% of sequences). Field CSC bacterial communities differed at each wreck site (P = 0.001), with oil-impacted sites differing from control sites. Lab CSC bacterial communities differed between all treatment groups (P = 0.005) and changed over the course of the experiment (P = 0.001). CSC bacterial species richness, diversity, and dominance increased with time across all treatments indicating the recruitment and establishment of microbial biofilms on CSCs. SW bacterial communities differed between treatment groups (P = 0.001), with the dispersant treatment being most dissimilar from all other treatments (P < 0.01), and changed over time (P = 0.001). Oil- and oil/dispersant-treated CSCs exhibited higher corrosion compared to dispersant and control treatments. These findings indicate that exposure to oil and/or dispersant may alter bacterial community composition and corrosion potential.

On February 5, 2003, three years after the creation of an inquiry commission about the Erika tanker-ship wreck, the principle of a new inquiry commission about the safety of maritime transports was decided by the French house of commons. Its mission is: to evaluate the efficiency of the existing measures of prevention of marine pollution by hydrocarbons, to examine if the preconized safety measures for the transport of dangerous or polluting products are effectively enforced, and to evaluate the status of the transposition of the European directives relative to the control of hazardous ships. This document is the first tome of the report made on behalf of this inquiry commission. It comprises four parts dealing with: 1 - the Prestige tanker-ship wreck and the pollution of Spanish and French coasts: similarities with the Erika wreck but differences in the conditions of crisis management, diverging accident analyses, problems encountered in Spain, a significantly improved management of the crisis by the French administration, the public opinion and the local economy, the global increase of maritime transport and the reduction of accidents frequency; 2 - the real improvements after the Erika wreck: the significant advances but their partial implementation, the acceleration of actions following the Prestige wreck; 3 - the expected and realistic perspectives: the sustain of the political will at the national scale, the concretizing of the European decisions and the follow up of the retained trends, the need for more outstanding evolutions at the international scale; 4 - the international liability and compensation regime: its limitation to the hydrocarbons pollution, the lack of victims indemnification in the case of chemical pollution, the need for an increase of the liability of all actors of the maritime transport and the improvement of the compensation system, a community compensation fund to compensate the inefficiencies of the international compensation mechanisms

The Oil Pollution Act of 1990 (''OPA'') and an even more problematic array of State pollution laws have raised the cost, and risk, of carrying oil into and out of the US. This report, prepared under contract to the US Department of energy's Office of Domestic and International Policy, examines the impact of Federal and State oil spill legislation on the tanker market. It reviews the role of marine transportation in US oil supply, explores the OPA and State oil spill laws, studies reactions to OPA in the tanker and tank barge industries and in related industries such as insurance and ship finance, and finally, discusses the likely developments in the years ahead. US waterborne oil imports amounted to 6.5 million B/D in 1991, three-quarters of which was crude oil. Imports will rise by almost 3 million B/D by 2000 according to US Department of energy forecasts, with most of the crude oil growth after 1995. Tanker demand will grow even faster: most of the US imports and the increased traffic to other world consuming regions will be on long-haul trades. Both the number of US port calls by tankers and the volume of offshore lightering will grow. Every aspect of the tanker industry's behavior is affected by OPA and a variety of State pollution laws

In 2010, bottles of beer containing viable bacteria of the common beer-spoilage species Lactobacillus backii and Pediococcus damnosus were recovered from a shipwreck near the Åland Islands, Finland. The 170-year quiescent state maintained by the shipwreck bacteria presented a unique opportunity to study lactic acid bacteria (LAB) evolution vis-a-vis growth and survival in the beer environment. Three shipwreck bacteria (one L. backii strain and two P. damnosus strains) and modern-day beer-spoilage isolates of the same two species were genome sequenced, characterized for hop iso-α-acid tolerance, and growth in degassed lager and wheat beer. In addition, plasmid variants of the modern-day P. damnosus strain were analyzed for the effect of plasmid-encoded genes on growth in lager beer. Coding content on two plasmids was identified as essential for LAB growth in modern lager beer. Three chromosomal regions containing genes related to sugar transport and cell wall polysaccharides were shared by pediococci able to grow in beer. Our results show that the three shipwreck bacteria lack the necessary plasmid-located genetic content to grow in modern lager beer, but carry additional genes related to acid tolerance and biofilm formation compared to their modern counterparts. © FEMS 2017.

Huijer, K.

2005-01-01

The trends in oil spills around the world over from 1995 to 2004 were examined and analyzed for possible influences on spill volumes and frequencies for incidents of 3 spill size classes. The International Tanker Owners Pollution Federation (ITOPF) has maintained a database since 1974 of all oil spills from tankers, combined carriers and barges. The number of oil spills has decreased significantly in the last 30 years despite a steady increase in maritime oil trade since the 1980s. The recent trends were identified by causes, locations, oil type, and shipping legislation. The causes include ship loading/discharging, bunkering, collisions, groundings, hull failures and fires. The types of oil spilt include bunker, crude, cargo fuel, white product and some unknowns. It was concluded that the decline in oil spills is due to a range of initiatives taken by governments and the shipping industry rather than any one factor. Some notable influences towards reduced number of spills include: the international convention for the prevention of pollution from ships of 1972, as modified by the Protocol of 1978; the international convention for the safety of life at sea of 1974; and the Oil Pollution Act of 1990. Results of investigations into the causes of spills serve the purpose of informing the international process to further prevent and reduce marine oil pollution due to tankers. 7 refs., 5 tabs., 12 figs

This report provides a systems analysis of a commercial Arctic Ocean submarine tanker system to carry fossil energy to markets. The submarine is to be propelled by a modular Phosphoric Acid Fuel Cell system. The power level is 20 Megawatts. The DOE developed electric utility type fuel cell will be fueled with methanol. Oxidant will be provided from a liquid oxygen tank carried onboard. The twin screw submarine tanker design is sized at 165,000 deadweight tons and the study includes costs and an economic analysis of the transport system of 6 ships. The route will be under the polar icecap from a loading terminal located off Prudhoe Bay, Alaska to a transshipment facility postulated to be in a Norwegian fjord. The system throughput of the gas-fed methanol cargo will be 450,000 barrels per day. The total delivered cost of the methanol including well head purchase price of natural gas, methanol production, and shipping would be $25/bbl from Alaska to the US East Coast. Of this, the shipping cost is $6.80/bbl. All costs in 1981 dollars

Operability Guidelines For Product Tanker In Heavy Weather In The Adriatic Sea

Mudronja Luka

2014-06-01

Full Text Available This paper presents operability guidelines for seafarers on a product tanker which navigates in the Adriatic Sea during heavy weather. Tanker route starts from the Otranto strait in the south to the island Krk in the north of Adriatic Sea. Heavy weather is caused by south wind called jugo (blowing from E-SE to SS-E, sirocco family. Operability guidelines are given based on an operability criteria platform for presenting ship seakeeping characteristics. Operability criteria considered in this paper are propeller emergence, deck wetness and bow acceleration of a product tanker. Limiting values of mentioned criteria determine sustainable speed. Heavy weather is described by extreme sea state of 7.5 m wave height. Wave spectrum used in this paper is Tabain spectrum which is developed specifically for Adriatic Sea. Seafarer's approach of decisions making in extreme weather is also shown and servers as a guideline for further research of the authors.

In-situ corrosion measurements of WWII shipwrecks in Chuuk Lagoon, quantification of decay mechanisms and rates of deterioration

Directory of Open Access Journals (Sweden)

Ian Donald Macleod

2016-03-01

Full Text Available This paper is based on a series of measurements taken on WWII historic shipwrecks that resulted from the effects of Operation Hailstone in February 1944 on the Japanese merchant fleet which was assembled in Chuuk lagoon, Federated States of Micronesia. More than 65 shipwrecks and 250 aircraft were sunk during two main bombing raids. The vessels lost covered a wide range of underwater orientation and water depths and so provided a perfect suite of corrosion experiments. Since the fuel on board the aircraft was either readily burnt at the time or was lost through volatilisation, the wrecked planes present no pollution problems today. However the bunker fuel kept inside on-board storage tanks does present a real conservation management crisis. In-situ measurements on many vessels have determined how water depth, the localised wreck topography, dissolved oxygen levels, temperature and salinity affects the corrosion rate of cast iron and mild steel. Thus corrosion rates can be calculated with confidence.

2012-12-01

Full Text Available This work presents the results of an investigation into risk events and their respective causes, carried out in ship maintenance undertakings in the logistical sector of the Brazilian oil industry. Its theoretical, conceptual positioning lies in those aspects related to risk management of the undertakings as instruments of support in decision making by executives in the tanker-maintenance business. The case-study method was used as an alternative methodology with a qualitative approach of an exploratory nature and, for the presentation of data, a descriptive format was chosen. Through the analysis of 75 risk events in projects of tanker docking it was possible to extract eight of the greatest relevance. The risk analysis facilitated the identification of actions aimed at their mitigation. As a conclusion it was possible to propose a risk-framework model in four categories, HSE (health, safety and the environment, technicians, externalities and management, designed to provide tanker-docking business executives and administrators, with evidence of actions to assist in their decision-making processes. Finally, the authors identified proposals for further study as well as showing the principal limitations of the study.

An understanding of the interactions between biological, chemical and physical dynamics is especially important for the adequate conservation of the Underwater Cultural Heritage. However, while physical and chemical processes are relatively well-investigated, the biological communities associated with these habitats are poorly studied. We compared the sessile community developed on panels of different materials placed on two historical shipwrecks, the Fougueux and the Bucentaure, from the Battle of Trafalgar (October 1805). Six materials used at the construction of vessels at the 18th and 19th centuries were selected: copper, brass, cast iron, carbon steel, pine and oak. The sessile community developed on the panels was studied two and 15 months after their immersion at the water to determine the effects of materials and environmental conditions (sediments, waves, hydrodynamic conditions, temperature and salinity) on ecological succession and the possible implications at the conservation of historical shipwrecks. On the Fougueux, the environmental conditions more strongly influenced the biological succession than the material type, with pioneer colonisers dominating the communities in both sampling periods. On the Bucentaure, exposed to more stable environmental conditions, the sessile community showed differences between sampling periods and among materials at the end of the experiment. Under these more stable environmental conditions, the material type showed a higher influence on the sessile community. Species that produce calcareous concretions developed on metallic panels, but were absent on wood panels, where the shipworm Teredo navalis was more abundant. The relationship between environmental conditions, sessile organisms and material type can influence the conservation status of the archaeological sites.

Full Text Available Educational evaluation, as the science of education, began to be developed and applied in Chile only starting from the sixties of the last century. Indeed, several Chilean educators were to his PhD to United States of America in these areas; among them are Mario Leyton and Erika Himmel, who specialized in curriculum and evaluation, through the approaches of Tyler and Bloom. Therefore, both were actively involved in the introduction into the country of two measurement systems: (1 selection for admission to the University, creating a standardized test, the academic aptitude test –paa– which was established from 1967 and remained until 2002 and from 2003 to date was changed to the university selection test –psu–; initially the paa contained only verbal and mathematical aptitude tests; knowledge tests were subsequently added specific (in mathematics, biology, physics, chemistry and Sciences social. (2 the measurement of achievements educational system school, both in basic education and medium from the 1970s with the called initially program of evaluation of educational achievement –per– and, subsequently, with the system of measurement of the quality of the teaching –simce–, which applies from 1988 until today, at the national level and at various levels of the school system: 4.° Basic, 8.° Basic and 2.° Medium, especially with tests of language and communication and mathematics. Both initiatives were directly involved Mario Leyton and Erika Himmel; the first to key positions in the Ministry of Education and the second as academic of the University of Chile and the Catholic University of Chile. Therefore, both have been recognized by the State with the National Prize of Sciences of Education in 2009 and 2011, respectively.

Tracking 800-year-old Shipments: An Archaeological Investigation of the Mado Shipwreck Cargo, Taean, Korea

Kim, Minkoo; Moon, Whan Suk

2011-12-01

This paper examines cargo from an 800-year-old shipwreck and discusses its implications in relation to the exchange networks and maritime transportation of the Goryeo period (A.D. 918-1392) in Korea. In 2007, two local fishermen fortuitously discovered porcelain vessels from a Goryeo-period shipwreck off the mid-western coast of the Korean peninsula. Underwater excavation conducted by the National Research Institute of Maritime Cultural Heritage (NRIMCH) revealed that the ship was carrying a myriad of cargoes destined for Gaegyeong, the capital of the Goryeo dynasty. Excavation indicates that the main body of the cargo was porcelain vessels produced in the southern part of the peninsula. Archaeobotanical investigation of the wreck deposits revealed that the ship was carrying crops such as rice ( Oryza sativa L.), broomcorn millet ( Panicum miliaceum L.), foxtail millet ( Setaria italica (L.) P. Beauv.), and buckwheat ( Fagopyrum esculentum Moench) bound for the capital. Among the recovered objects were 73 wooden cargo tags with Chinese letters. These tags, equivalent to the modern day air bill, contained detailed information about the senders, recipients, and shipped goods. These findings indicate that during the Goryeo period maritime transportation played an important role in the interpersonal exchange of products over long distances.

Design challenges for large Arctic crude oil tanker

International Nuclear Information System (INIS)

Iyerusalimskiy, A.; Noble, P.

2008-01-01

The Vasily Dinkov vessel was delivered by Samsung Heavy Industries shipyard to Russian ship-owner Sovcomflot. It is the largest icebreaking tanker ever built. The vessel was designed and constructed to transport crude oil from the Varandey offshore terminal in the southeastern Barents Sea to a transshipment location near Murmansk, Russia. The vessel is under long-term charter for Naryanmarneftegas, a joint venture of Lukoil and ConocoPhillips. The new ship was constructed strictly to the requirements, specification, and concept design provided by the charterer. The Varandey oil transportation concept and the vessel operational profile resulted in some conflicting requirements, compromising technical solutions, and assumptions yet to be proven in operation. This paper described the design challenges and selected approach to solve the solution to the tanker key design elements. These included the ice transit and other Arctic environmental challenges; open water performance issues; and icebreaking hull structure design challenges associated with modern shipbuilding technology standards and cost efficiency. The principle characteristics of the Vasily Dinkov were first presented and the Varandey crude oil transportation system was also described. Several features have made the Vasily Dinkov the most advanced icebreaking tanker to date, such as the icebreaking concept which has expanded the capability of both traditional icebreaking ships fitted with the icebreaker bow and double acting ships intended to operate astern only in the ice; the largest azimuthal twin screw propulsion plant for the Arctic with highest ice torque capacity ever specified for cargo vessel; and the first customized, automated, asymmetric steering control system designed to improve open water maneuverability and steering stability of podded vessels. It was concluded that the transportation system, the overall vessel concept and many of the vessel features require validation based on operational

Ultimate strength performance of tankers associated with industry corrosion addition practices

Full Text Available In the ship and offshore structure design, age-related problems such as corrosion damage, local denting, and fatigue damage are important factors to be considered in building a reliable structure as they have a significant influence on the residual structural capacity. In shipping, corrosion addition methods are widely adopted in structural design to prevent structural capacity degradation. The present study focuses on the historical trend of corrosion addition rules for ship structural design and investigates their effects on the ultimate strength performance such as hull girder and stiffened panel of double hull oil tankers. Three types of rules based on corrosion addition models, namely historic corrosion rules (pre-CSR, Common Structural Rules (CSR, and harmonised Common Structural Rules (CSRH are considered and compared with two other corrosion models namely UGS model, suggested by the Union of Greek Shipowners (UGS, and Time-Dependent Corrosion Wastage Model (TDCWM. To identify the general trend in the effects of corrosion damage on the ultimate longitudinal strength performance, the corrosion addition rules are applied to four representative sizes of double hull oil tankers namely Panamax, Aframax, Suezmax, and VLCC. The results are helpful in understanding the trend of corrosion additions for tanker structures

The application of strengths, weaknesses, opportunities and threats (SWOT) analysis to formulation of strategy concerned with the safe carriage of bulk liquid chemicals in maritime tankers was examined in this study. A qualitative investigation using SWOT analysis has been implemented successfully for ships that are designed to carry liquid chemicals in bulk. The originality of this study lies in the use of SWOT analysis as a management tool to formulate strategic action plans for ship management companies, ship masters and officers for the carriage of dangerous goods in bulk. With this transportation-based SWOT analysis, efforts were made to explore the ways and means of converting possible threats into opportunities, and changing weaknesses into strengths; and strategic plans of action were developed for safer tanker operation.

Transporting US oil imports: The impact of oil spill legislation on the tanker market. Draft final report

The country of Jordan is characterized by severe water scarcity and deficient public water supply networks. To address these issues, Jordan's water sector authorities have adopted a water rationing scheme implemented by interrupting piped water supply for several days per week. As in many arid countries around the world, this has led to the emergence of private markets of small-scale providers, delivering water via tanker trucks. On the one hand, these markets play a crucial role in meeting residential and commercial water demands by balancing the shortcomings of the public supply system. On the other hand, providers partially rely on illegal abstractions from rural ground and surface water sources, thereby circumventing regulatory efforts to conserve these resources. Private tanker water markets, therefore, provide a substantial contribution to consumer welfare while jeopardizing freshwater resource sustainability. Thus, a better understanding of these markets is of great importance for the formulation of policy interventions pursuing freshwater sustainability in a socially acceptable manner. Direct assessments of the size of these markets or their responses to policy interventions are, however, impeded by their partially illegal nature and the resulting lack of available information. To overcome this data collection challenge, we use a hydroeconomic multi-agent model developed in the Jordan Water Project to indirectly simulate country-wide tanker water market activities on the basis of demand and supply estimates. The demand for tanker water is conceptualized as a residual demand, remaining after a water user has depleted all available cheap and qualitatively reliable piped water. It is derived from residential and commercial demand functions on the basis of survey data. Tanker water supply is determined by farm simulation models calculating the groundwater pumping cost and the agricultural opportunity cost of tanker water. Finally, a spatial market algorithm

In arid countries around the world, markets of private small-scale water providers, mostly delivering water via tanker trucks, have emerged to balance the shortcomings of public water supply systems. While these markets can provide substantial contributions to meeting customers' water demands, they often partially rely on illegal water abstractions, thus imposing an unregulated and unmonitored strain on ground and surface water resources. Despite their important impacts on water users' welfare and resource sustainability, these markets are still poorly understood. We use a multi-agent, hydroeconomic simulation model, developed as part of the Jordan Water Project, to investigate the role of these markets in a country-wide case-study of Jordan. Jordan's water sector is characterized by a severe and growing scarcity of water resources, high intermittency in the public water network, and a strongly increasing demand due to an unprecedented refugee crisis. The tanker water market serves an important role in providing water from rural wells to households and commercial enterprises, especially during supply interruptions. In order to overcome the lack of direct data about this partially illegal market, we simulate demand and supply for tanker water. The demand for tanker water is conceptualized as a residual demand, remaining after a water user has depleted all available cheap and qualitatively reliable piped water. It is derived from residential and commercial demand functions on the basis of survey data. Tanker water supply is determined by farm simulation models calculating the groundwater pumping cost and the agricultural opportunity cost of tanker water. A market algorithm is then used to match rural supplies with users' demands, accounting for survey data on tanker operators' transport costs and profit expectations. The model is used to gain insights into the size of the tanker markets in all 89 subdistricts of Jordan and their responsiveness to various policy

The Tantura F shipwreck was a coaster or a fishing vessel about 15.7 m long, discovered in the Dor/Tantura lagoon, Israel in 1995. It was dated to between the mid-7th and the end of the 8th centuries CE. Among the finds excavated were two T-shaped type iron anchors. Of the two anchors, one (anchor A) was thoroughly studied by archaeometallurgical methods in order to identify forge-welding lines, to determine the welding quality and to understand the manufacturing technology. The examinations included X-ray radiography, XRF analysis, optical microscopy, SEM/EDS observation and analysis, OES analysis and microhardness tests. The investigation included characterization of the composition, microstructure, thermal treatments, forge-welding junctions and slag analysis. The results revealed a heterogeneous microstructure, rich in glassy, fayalite and wüstite slag. Iron based phases included ferrite, pearlite, cementite and Widmanstätten plates, all typical to wrought iron. The forge-welds of Anchor A were located. Each arm was made of one piece, weighing about 2.5–3 kg and the shank was made of a few 1.5–2 kg pieces. The second anchor (anchor B) was only briefly examined visually and with a few radiographs, which support the results from anchor A. The research results revealed significant information about T-shaped anchors and their manufacturing process, including hot-working processes without any additional heat treatments, and folding techniques. The microstructure was similar to other ancient simple tools such as saws, sickles, axes and mortise chisels, and though the technology to make complicated structures and objects, such as swords, existed at that time, the anchors did not require this sophistication; thus simpler techniques were used, presumably because they were more cost-effective. - Highlights: ► Tantura F was a coaster dated to mid-7th–end-8th centuries. ► Two iron anchors were discovered at the Tantura F shipwreck-site. ► Anchor A was

Tanker self-help spill recovery systems

Energy Technology Data Exchange (ETDEWEB)

Smedley, J B; Wainwright, J G; Ehman, T K

1991-12-01

An investigation was conducted of the circumstances in which oil spills occur from tankers at sea by analyzing available historical oil spill data. A data base of marine oil spills greater than 134 tonnes occurring from 1974 and June 1990, included in an appendix, was among the information analyzed. The analysis showed that marine oil spills of 5,000 tonnes and greater account for 39.4% of the accidents yet 94.7% of the total spilled quantity; 84% of those spills occur in vessels of 20,000 deadweight tonnes and larger. Of spills over 5,000 tonnes, 78.5% occur outside of harbor or pier areas where spill response equipment may not be readily available. Over 50% of spills are caused by groundings or collisions where the vessel crew might be able to respond in mitigating and controlling the outflow of oil. The review suggested that tanker self-help systems warrant serious consideration. Potential self-help systems are described, ranging from additives such as bioremediation, dispersants, and solidifiers to equipment such as portable pumps, booms, and skimmers. Candidate systems were examined in terms of their safety, ease of operation, practicability, and effectiveness. Their possible performance was then assessed for the case of major marine oil spills that have occurred in Canadian waters. Four systems are identified as potential candidates for further evaluation and possible implementation: internal oil transfer, hydrostatic loading, external oil lightering, and contingency planning. A system design is evaluated and its benefits and possible implementation are outlined, based on integration of the preferred attributes of the above four options. Recommendations for implementation are also provided. 28 refs., 6 figs., 33 tabs.

The Erika tanker ship wreck (December 12, 1999) has led to direct wastes (petroleum products) and indirect wastes (oil contaminated matters and instruments) and also to a public unfriendliness towards Total oil company. This situation has led the company to mobilize exceptional means for the cleansing of the environment and the processing of wastes. The success of this operation has been possible thanks to the know-how collaboration of the petroleum (Total company) and building industry (Brezillon company) sectors, which usually do not work together in environmental activities. 270000 t of wastes have been processed in 2 years. 96 % have been cleanly recycled by washing processes. The macro wastes (4%) have been incinerated for steam/electricity generation. The argillaceous sediments have been valorized in cement industry, while the sand and rocks have been valorized as road filling materials. This short paper recalls the historical context of the Erika wreck, Total's commitments, the basic data, the physico-chemical treatment of wastes and the waste processing status. (J.S.)

Population growth and development are associated with increased water demand that often exceeds the capacity of existing resources, resulting in water shortages, particularly in urban areas, where more than 60% of the world's population resides. In many developing communities, shortages often force households to depend on water tankers amongst other potential sources for the delivery of water for domestic and/or potable use. While water tankers have become an integral part of the water supply system in many countries, the sector is often unregulated and operates with little governmental supervision. Users are invariably unaware of the origin or the quality of purchased water. In an effort to better assess this sector, a field survey of water vending wells and tankers coupled with a water quality sampling and analysis program was implemented in a pilot semi-arid urban area (Beirut, Lebanon) to shed light on the environmental and socio-economic impacts of the water tanker sector. Total dissolved solids (TDS), chloride (Cl - ), and microbial loads exceeded drinking water quality standards. While TDS and Cl - levels were mostly due to saltwater intrusion in coastal wells, tankers were found to be a significant source of total coliforms. Delivered water costs varied depending on the tanker size, the quality of the distributed water, and pre-treatment used, with a markup of nearly 8-24 folds of the public water supply and an equivalent economic burden of 16% of the average household income excluding environmental externalities of water quality. The study concludes with a management framework towards consumer protection under integrated supply and demand side measures. Copyright © 2016 Elsevier Ltd. All rights reserved.

A new arrangement with nonlinear sidewalls for tanker ship storage panels

Science.gov (United States)

Ketabdari, M. J.; Saghi, H.

2013-03-01

Sloshing phenomenon in a moving container is a complicated free surface flow problem. It has a wide range of engineering applications, especially in tanker ships and Liquefied Natural Gas (LNG) carriers. When the tank in these vehicles is partially filled, it is essential to be able to evaluate the fluid dynamic loads on tank perimeter. Different geometric shapes such as rectangular, cylindrical, elliptical, spherical and circular conical have been suggested for ship storage tanks by previous researchers. In this paper a numerical model is developed based on incompressible and inviscid fluid motion for the liquid sloshing phenomenon. The coupled BEM-FEM is used to solve the governing equations and nonlinear free surface boundary conditions. The results are validated for rectangular container using data obtained for a horizontal periodic sway motion. Using the results of this model a new arrangement of trapezoidal shapes with quadratic sidewalls is suggested for tanker ship storage panels. The suggested geometric shape not only has a maximum surrounded tank volume to the constant available volume, but also reduces the sloshing effects more efficiently than the existing geometric shapes.

Effects of Common Structural Rules on hull-girder reliability of an Aframax oil tanker

2008-01-01

This paper aims at quantifying the changes in notional reliability levels that result from redesigning an existing Aframax tanker to comply with the Common Structural Rules (CSR) for double-hull oil tankers. The probability of structural failure is calculated using the first-order reliability method. The evaluation of the wave-induced load effects that occur during long-term operation of the ship in the seaway is carried out in accordance with the International Association of Classification Societies (IACS)-recommended procedure, while transfer functions are calculated using the sink-source 3D linear method. The still-water loads are defined on the basis of a statistical analysis of loading conditions from the loading manual. The ultimate collapse bending moment of the midship cross section, which is used as the basis for the reliability formulation, is evaluated by progressive collapse analysis and by a single-step procedure according to CSR. The reliability assessment is performed for 'as-built' and 'corroded' states of the existing ship and a reinforced ship complying with CSR. It is shown that the hull-girder failure probability of an Aframax tanker is reduced several times due to the reinforcements according to CSR. Sensitivity analysis and a parametric study are performed to investigate the variability of results with the change of parameters of pertinent random variables within their plausible ranges. Finally, differences between load combination approaches by Ferry-Borges and Castanheta method and Turkstra's rule are investigated

Low-head air stripper treats oil tanker ballast water

International Nuclear Information System (INIS)

Goldman, M.

1992-01-01

Prototype tests conducted during the winter of 1989/90 have successfully demonstrated an economical design for air stripping volatile hydrocarbons from oily tanker ballast water. The prototype air stripper, developed for Alyeska's Ballast Water Treatment (BWT) facility in Valdez, Alaska, ran continuously for three months with an average removal of 88% of the incoming volatile organics. Initially designed to remove oil and grease compounds from tanker ballast water, the BWT system has been upgraded to a three-step process to comply with new, stringent regulations. The BWT biological oxidation process enhances the growth of bacteria present in the incoming ballast water through nutrient addition, aeration, and recirculation within a complete-mixed bioreactor. The average removal of BETX is over 95%, however, occassional upsets required the placement of a polishing air stripper downstream of the aeration tanks. Packed-tower air stripping was investigated but deemed economically unfeasible for a facility that would only occasionally be used. Twelve feet of excess gravity head in the existing BWT hydraulic gradeline were employed to drive the air stripper feed. This limited the stripper packing depth to 8 feet and imposed constraints on the design of the inlet water and air distributors. Water distribution, air flow, temperature effects, and fouling from constituents in the ballast water were investigated. The prototype was operated under water and air flow conditions similar to those specified for the full-scale unit, and at a range of test conditions above and below the normal design conditions

Satellite remote sensing is well known to play a critical role in monitoring marine accidents such as oil spills, yet the recent SANCHI oil tanker collision event in January 2018 in the East China Sea indicates that traditional techniques using synthetic aperture radar or daytime optical imagery could not provide timely and adequate coverage. In this study, we show the unprecedented value of Visible Infrared Imaging Radiometer Suite (VIIRS) Nightfire product and Day/Night Band data in tracking the oil tanker's drifting pathway and locations when all other means are not as effective for the same purpose. Such pathway and locations can also be reproduced with a numerical model, with root-mean-square error of days of the tanker's sinking reveals much larger oil spill area (>350 km2) than previous reports, the impact of the spilled condensate oil on the marine environment requires further research.

Oil-tanker waste-disposal practices: A review

International Nuclear Information System (INIS)

1992-01-01

In the spring of 1991, the Environmental Protection Agency, Region 10 (EPA), launched an investigation into tanker waste disposal practices for vessels discharging ballast water at the Alyeska Pipeline Services Company's Ballast Water Treatment (BWT) facility and marine terminal in Valdez, Alaska. It had been alleged that the Exxon Shipping Company was transferring 'toxic wastes originating in California' to Valdez. In response, EPA decided to examine all waste streams generated on board and determine what the fate of these wastes were in addition to investigating the Exxon specific charges. An extensive Information Request was generated and sent to the shipping companies that operate vessels transporting Alaska North Slope Crude. Findings included information on cargo and fuel tank washings, cleaning agents, and engine room waste

Full text : Considering all types of risks (technical, operational, natural hazards (e.g. geo-hazards) and third party intrusion), the underground pipelines constructed in accordance with the international standards are the most safe and reliable system for oil transportation. Statistical data provided by CONCAWE and US Department of Transportation confirms that the pipeline related spills are rare and mainly related to the old pipelines. Georgia's experience yet confirms the general sound guess that the situation in our countries is not the same as in western Europe or USA and accordingly the CONCAWE statistical data can not be applied mechanically. Two spills (although small and manageable), during the recent 4 years and some discovered illegal hot-taps on the Baku-Supsa pipeline indicate that the issue of third party intrusion risks is much higher in the region and well organized security system is required to protect the pipeline from intentional damage. Of course the pipeline system can not function isolated and it is integrated with the other systems of oil transportation, mainly with off-shore terminals and tankers. The most significant of the recorded pollution damages are related to the tanker collisions (like Prestige and Exxon Valdez cases). The basic fact, which we would like to stress, is that the environmental risks related to the tanker collisions are much higher for such confined or semi-confined systems as Black and Caspian seas. The overloading of the Black Sea transportation capacity and especially its limiting narrow point - the Bosporus will inevitably lead in future to the implementation of the restrictive measures limiting transportation of oil by tankers in the Black Sea. Therefore, the role of the BTC pipeline as major transportation system will increase significantly. We consider that responsibility of the scientific society is to facilitate this process as soon as the BTC pipeline is functional. The railway transportation of oil is quite

Between March 20 and April 6, 2012, the NOAA Ship Okeanos Explorer served as a platform for ship-board and shore-side scientists to explore the deep Gulf of Mexico, targeting the northern West Florida Escarpment, DeSoto Canyon, the vicinity (within 11km) of the Deepwater Horizon (DWH) well, and deepwater shipwrecks. We systematically explored and discovered natural hydrocarbon seeps, diverse coral ecosystems, wooden and iron-hulled shipwrecks more than 100 years old colonized by coral communities, and sperm whale habitat between 600 and 1200m. A total of sixteen dives took advantage of new and recent maps to explore and groundtruth both hard and soft-bottom habitats, from cretaceous carbonates to mounds of coral rubble. The final ROV dive successfully groundtruthed expected methane-release areas imaged by the ship's mapping systems up to 1150m above the seafloor. The source of the mapping imagery was a stream of bubbles issuing from beneath thriving seep mussel communities. We visited five sites in the Mississippi Canyon (MC) area (lease blocks MC294, MC297, MC388, MC255, and MC036; the DWH incident took place in MC252). These sites were 11.3 km SW, 6.8 km SW, 7.6 km SW, 25.7 km E, and 27.4 km to the NE of the DWH, respectively. We used high-definition imaging systems on the Little Hercules ROV and Seirios camera platform to document more than 130 coral colonies and over 400 associated individual animals to continue to assessing the impact of the Deepwater Horizon oil spill. All of these efforts were conducted to provide fundamental knowledge of unknown and poorly known regions, ecosystems, and items of historical significance in the deep Gulf of Mexico.

Effect of Baffles on the Sloshing in Road Tankers Carrying LPG: A Comparative Numerical Study

J. L. Bautista-Jacobo

2015-01-01

Full Text Available This work presents a comparative numerical study of the effect of using baffles, and its design, on the behavior of sloshing in a partially filled road tanker carrying LPG. Navier-Stokes equations and standard k-ε turbulence model are used to simulate fluid movement; the Volume of Fluid (VOF method is used to track the liquid-gas interface. Velocity distributions, sloshing stabilization times, and contours of turbulent kinetic energy, which are of high importance in choosing the best design of baffles, are shown. The results show sloshing stabilization times of 22 and 21 s for road tankers with cross-shaped (Type I and X-shaped (Type II baffles, respectively, finding lower values of turbulent kinetic energy for Type II design, being, therefore, the best design of baffles for damping of sloshing and vehicle control among studied ones.

The explosion of a road tanker transporting LNG (one person killed, two injured) is studied. The analysis shows that the explosion, which followed a two-step mode as for the failure of the vessel, could have been a boiling liquid expanding vapor explosion (BLEVE). The overpressure and thermal radiation have been estimated and related to the effects observed. Only a relatively small part of the energy released in the explosion was manifested in the pressure wave. The large fragments (the three pieces into which the tank was broken) and the truck motor were ejected at various distances along the tank's main axis. (author)

Muhammad Badrus Zaman

2017-09-01

Full Text Available Every ship project would not be apart from risk and uncertainty issues. The inappropriate risk assessment process would have long-term impact, such as financial loss. Thus, risk and uncertainties analysis would be a very important process in financial feasibility determination of the project. This study analyzes the financial feasibility of 17,500 LTDW tanker project. Risk and uncertainty are two differentiated terminologies in this study, where risk focuses on operational risk due to shipbuilding process nonconformity to shipowner finance, while uncertainty focuses on variable costs that affect project cash flows. There are three funding scenarios in this study, where the percentage of funding with own capital and bank loan in scenario 1 is 100% : 0%, scenario 2 is 75% : 25%, and scenario 3 is 50% : 50%. Monte Carlo simulation method was applied to simulate the acceptance criteria, such as net present value (NPV, internal rate of return (IRR, payback period (PP, and profitability index (PI. The results of simulation show that 17,500 LTDW tanker project funding by scenario 1, 2 and 3 are feasible to run, where probability of each acceptance criteria was greater than 50%. Charter rate being the most sensitive uncertainty over project's financial feasibility parameters.

Multifractal cross-correlations between crude oil and tanker freight rate

Analysis of crude oil price and tanker freight rate volatility attract more attention as the mechanism is not only the basis of industrialization but also a vital role in economics, especially after the year 2008 when financial crisis notably blew the maritime transportation. In this paper, we studied the cross-correlations between the West Texas International crude oil (WTI) and Baltic Exchange Dirty Tanker Index (BDTI) employing the Multifractal Detrended Cross-Correlation Analysis (MF-DCCA). Empirical results show that the degree of short-term cross-correlation is higher than that in the long term and that the strength of multifractality after financial crisis is larger than that before. Moreover, the components of multifractal spectrum are quantified with the finite-size effect taken into consideration and an improved method in terms of constructing the surrogated time series provided. Numerical results show that the multifractality is generated mostly from the nonlinear and the fat-tailed probability distribution (PDF) part. Also, it is apparent that the PDF part changes a lot after the financial crisis. The research is contributory to risk management by providing various instructions for participants in shipping markets. Our main contribution is that we investigated both the multifractal features and the origin of multifractality and provided confirming evidence of multifractality through numerical results while applying quantitative analysis based on MF-DCCA; furthermore, the research is contributory to risk management since it provides instructions in both economic market and stock market simultaneously. However, constructing the surrogated series in order to obtain consistence seems less convincing which requires further discussion and attempts.

Leaking tankers: how much oil was spilled?

International Nuclear Information System (INIS)

Simecek-Beatty, D. A.; Lehr, W. J.; Lankford, J. F.

1997-01-01

A model to estimate leak rates from tankers has been developed for use in emergency situations when more direct oil-loss estimation methods are not available. The model includes algorithms for gravity outflow and air and water ingestion. Three laboratory tests were conducted using fresh water and canola oil to evaluate the model output. Comparison with results from the laboratory experiments indicate good correlation of model results with measured data. However, it is not yet possible in the case of very large crude carriers to answer the question 'how much oil was spilled?' Sensitivity analysis and further laboratory testing were suggested to determine the effect of factors such as: pressure vacuum relief valves that prevent cavitation in the event of tank puncture; changing outside water levels due to wave and tidal action; tank and hole dimensions; and the amount and density of the product.10 refs., 4 figs

In spring 1990, the Federal German Minister for Education, Science, Research and Technology (BMBF) commissioned the team from the Federal Institute for Materials Research and Testing (BAM), DEKRA, Daimler-Benz, the Federal Road Research Institute (BASt) with the University of Cologne, Ellinghaus and TUeV Rheinland (project leader) to perform the research project `THESEUS` (the acronym THESEUS comes from the German `Tankfahrzeuge mit hoechst erreichbarer Sicherheit durch experimentelle Unfallsimulation`, which translates as `achieving maximum possible road transport tanker safety by means of experimental accident simulation`). Arting from an analysis of road transport tanker accidents, crash tests and overturn tests were performed and supplemented by investigations of road transport tanker components and accompanying complex calculations of the failure processes. Parallel to this, the static side-tilt stability of road transport tankers was determined on a tilting test platform. The causes of and constructive possibilities for avoiding overturning, which is the most common cause of accidents in which hazardous materials escape, wewre analysed in dynamic driving tests with supplementary computer simulation. Various measures for improving the safety of road transport tankers were determined and subjected to a cost-benefit analysis. (orig.)

Comparative analysis among deterministic and stochastic collision damage models for oil tanker and bulk carrier reliability

Directory of Open Access Journals (Sweden)

2018-01-01

Full Text Available The incidence of collision damage models on oil tanker and bulk carrier reliability is investigated considering the IACS deterministic model against GOALDS/IMO database statistics for collision events, substantiating the probabilistic model. Statistical properties of hull girder residual strength are determined by Monte Carlo simulation, based on random generation of damage dimensions and a modified form of incremental-iterative method, to account for neutral axis rotation and equilibrium of horizontal bending moment, due to cross-section asymmetry after collision events. Reliability analysis is performed, to investigate the incidence of collision penetration depth and height statistical properties on hull girder sagging/hogging failure probabilities. Besides, the incidence of corrosion on hull girder residual strength and reliability is also discussed, focussing on gross, hull girder net and local net scantlings, respectively. The ISSC double hull oil tanker and single side bulk carrier, assumed as test cases in the ISSC 2012 report, are taken as reference ships.

Assessing the impact of future climate change on North Atlantic tropical cyclone (TC) activity is of crucial societal importance, but the limited quantity and quality of observational records interferes with the skill of future TC projections. In particular, North Atlantic TC response to radiative forcing is poorly understood and creates the dominant source of uncertainty for twenty-first-century projections. Here, we study TC variability in the Caribbean during the Maunder Minimum (MM; 1645-1715 CE), a period defined by the most severe reduction in solar irradiance in documented history (1610-present). For this purpose, we combine a documentary time series of Spanish shipwrecks in the Caribbean (1495-1825 CE) with a tree-growth suppression chronology from the Florida Keys (1707-2009 CE). We find a 75% reduction in decadal-scale Caribbean TC activity during the MM, which suggests modulation of the influence of reduced solar irradiance by the cumulative effect of cool North Atlantic sea surface temperatures, El Niño-like conditions, and a negative phase of the North Atlantic Oscillation. Our results emphasize the need to enhance our understanding of the response of these oceanic and atmospheric circulation patterns to radiative forcing and climate change to improve the skill of future TC projections.

Full Text Available The safety and risk assessment of dangerous cargo operations in oil and chemical tankers is a necessary process to prevent possible accidents during these operations. Fire and explosion are the major accidents encountered in tanker operations. In this study, a model was constructed through the Fuzzy Bayes Network Method for the probabilistic relationships between the causes of fire and explosion accidents that could occur during the tank cleaning process. The study is composed of two stages. Firstly, the variables that are the subject of the problem and that constitute the graphical structure of the Bayes Networks are identified. Then, expert opinion was sought as the statistical data on accident reports were not recorded properly while identifying the conditional probability of the relationships between the variables. Linguistic variables whose fuzzy membership functions were identified were used in detecting the probabilities. The findings of the sensitivity test revealed that the major reasons that could lead to fire and explosion during the tank cleaning process are ignition sources, reaction and safety culture.

Current progress in underwater archeology is based on a rich arsenal of high-tech appliances, among which sonar technology plays a key role; it enables scientists not only to detect submerged archeological objects, but to examine them in high definition without having to conduct diving operations or use expensive underwater unmanned vehicles. While the majority of sensational scientific discoveries using sonar have been made in saltwater environments, freshwater ones, rivers in particular, have seen limited activity. The river Yenisei in central Siberia contains an unrecorded number of shipwrecks that await being discovered and studied. In this article we focus on the peculiarities of using sonar for detecting archeological sites on the Yenisei. This article is based on the results of the 2016 expedition, which has determined the location of Thames, a 19th century British steam schooner which was wrecked on the Yenisei.

Entertainment-education (E-E) approaches for young audiences continue to evolve in order to keep stride with younger generations' affinity for technology. E-E and novelas have been used with a wide variety of audiences in the United States, in particular hard-to-reach Latino populations, and have demonstrated effectiveness in disseminating culturally relevant prevention information for a wide variety of health-related risk factors and behaviors. This study discusses the formative research and active engagement of Latino youth living in Langley Park, Maryland, for the development and filming of an innovative 6-episode webnovela titled Victor and Erika (V&E). V&E is part of a larger branding strategy of the Adelante Positive Youth Development intervention that seeks to prevent substance abuse, sexual risk, and interpersonal violence among Latino youth; V&E is also an intervention component. The V&E webnovela is a dramatic portrayal of the lives of 2 immigrant Latino teenagers that also disseminates risk prevention messages. The storyline represents the turning the corner (to a better life) theme that underlies the Adelante intervention brand. Formative research was conducted for character development (n = 20) and creative development of the episodes (n = 14). Results of the formative research showed that youth recommended inclusion of the following topics in V&E episodes: sex, unintended pregnancy, fidelity, trust, family dynamics, immigration status, violence, school dropout, respect, home life, and poverty. Detailed character and episode descriptions are provided, and the implications of using the V&E series as a tool for in-person and online engagement of youth and the dissemination of prevention messages are also discussed.

Oil coastal tanker maintenance and availability

2008-07-01

ANCAP (Government's Oil Company of Uruguay) owns a 4000 DWT oil coastal tanker which is mainly used for oil transport in the River Plate, Uruguay and Parana rivers. Availability of the ship is critical because of shortage of available vessels in the region. Full maximum draught of the vessel is 4m , so it can navigate in very shallow waters as it is the case of some places in the Uruguay and Parana rivers. Although the ship was built in 1979, it is a complete double hull, powered by two twin main engines and propellers. Since 1994, several changes in maintenance management have been introduced, in order to increase the availability, thus increasing the total oil volume yearly transported. These changes affected several maintenance items and they also included a modification in the design of part of the cargo tank floors of the ship. As a result of these changes, an increase of 60% of the oil derivatives volume transported yearly was achieved. In this paper, some of the important improvements on maintenance practises and management are described, together with a quantification of their influence on vessel's availability and overall maintenance costs.

Przywarty Marcin

2015-04-01

Full Text Available This paper presents assumptions and process of the forming of a risk assessment model for collision between a passenger ferry departing from or approaching port of Świnoujście and a chemical tanker carrying a dangerous cargo. In order to assess navigational safety on the basis of data obtained from AIS system, were prepared probabilistic domains of ships, which made it possible to estimate number of navigational incidents as well as their spatial distribution, that consequently allowed to determine potentially dangerous areas. The next phase was formulation of a simulative model intended for the calculating of probability of collision between the ferry and chemical tanker as well as the determining of characteristic scenarios for such collision. This paper presents also an analysis of consequences of the collision with taking into consideration a damage of cargo tanks.

Privatization by Other Means: Social Power, Tankers and Techno-Assemblages of Water Supply in Amman, Jordan.

Science.gov (United States)

Mustafa, D.

2016-12-01

Combined piped and tanker based water supply systems have become a ubiquitous feature of urban waterscapes in the global South. Jordanian water sector, and Amman in particular has been a recipient of considerable international financial and technical assistance over the past decades. The international assistance has coupled with the Jordanian state's own pro-market ideological stance, and its political compulsions to spawn a techno-social assemblage of water supply that represents a hybrid state and commercial water supply system. I present the results of a field study in Amman, Jordan on water tankers and water users to understand the techno-political underpinnings of the hybrid system and its impact on differential access to water. I explore how Actor Network Theory (ANT) based analysis of tankers, suction pumps and piped water system and their materiality may explain differential access to water. But that exploration is inflected by a larger political ecological concern with questions of power and discourses about citizenship and claim making on the state. I find that ANT based focus on water technologies, while ontologically fertile, and epistemologically innovative, is nevertheless politically barren. Much richer political insights are to be gained from structural and post-structurally based investigations of the discursive and material drivers of the techno-social assemblages of water supply. The technologies don't just neutrally impact water access, but seem to almost intentionally favour the powerful over the powerless. Surely the political agency must not reside in inanimate technologies but in the social actors and structures that fashion those technologies, and configure them such to reinforce geographies of power. I call for a renewed focus on social power and how its impact on lived geographies is mediated by technology.

2009-01-01

A probabilistic maintenance and repair analysis of tanker deck plates subjected to general corrosion is presented. The decisions about when to perform maintenance and repair on the structure are studied. Different practical scenarios are analyzed and optimum repair times are proposed. The optimum repair age and intervals are defined based on the statistical analysis of operational data using the Weibull model and some assumptions about the inspection and time needed for repair. The total cost is calculated in normalized form.

Economic impacts of oil spills: Spill unit costs for tankers, pipelines, refineries, and offshore facilities

International Nuclear Information System (INIS)

1993-01-01

The impacts of oil spills -- ranging from the large, widely publicized Exxon Valdez tanker incident to smaller pipeline and refinery spills -- have been costly to both the oil industry and the public. For example, the estimated costs to Exxon of the Valdez tanker spill are on the order of $4 billion, including $2.8 billion (in 1993 dollars) for direct cleanup costs and $1.125 billion (in 1992 dollars) for settlement of damages claims caused by the spill. Application of contingent valuation costs and civil lawsuits pending in the State of Alaska could raise these costs appreciably. Even the costs of the much smaller 1991 oil spill at Texaco's refinery near Anacortes, Washington led to costs of $8 to 9 million. As a result, inexpensive waming, response and remediation technologies could lower oil spin costs, helping both the oil industry, the associated marine industries, and the environment. One means for reducing the impact and costs of oil spills is to undertake research and development on key aspects of the oil spill prevention, warming, and response and remediation systems. To target these funds to their best use, it is important to have sound data on the nature and size of spills, their likely occurrence and their unit costs. This information could then allow scarce R ampersand D dollars to be spent on areas and activities having the largest impact. This report is intended to provide the ''unit cost'' portion of this crucial information. The report examines the three key components of the US oil supply system, namely, tankers and barges; pipelines and refineries; and offshore production facilities. The specific purpose of the study was to establish the unit costs of oil spills. By manipulating this key information into a larger matrix that includes the size and frequency of occurrence of oil spills, it will be possible' to estimate the likely future impacts, costs, and sources of oil spills

2007-10-01

The aim of this work was to study the variability in the composition of bulk milk mixtures of fat-soluble compounds (vitamins A and E, carotenoids, and terpenoids) and assess the links with milk production conditions. Milk from 10 collection trips in the French department of the Haute-Loire (10 to 36 herds per trip) was sampled in the tanker twice during the winter period and 3 times during the grazing season. The collection trips differed in their altitude (440 to 1,150 m) and the forage system (grass or based on corn silage). Vitamins A and E, carotenoids, and terpenoids of the 50 tanker loads of milk were analyzed. Data of milk production conditions in the 204 farms made it possible to constitute indicators for the collection trip and to define 50 mean herds. The relationships between mean herd characteristics (breed, stage of lactation, and feed) and milk characteristics were investigated. The constituents of tanker loads of milk were comparable to those observed in milk produced by groups of animals receiving contrasting diets (rich in concentrate or corn silage vs. pasture). The characteristics of the milk differed according to the period; those produced at grazing were more yellow (1.02 +/- 0.4; mean of difference) and richer in beta-carotene, lutein, vitamin E (2.0 +/- 1.2, 0.23 +/- 0.12, and 6.1 +/- 5.0 mug/g of fat, respectively), and sesquiterpenes (2.7 +/- 2.5) than winter. The variations observed for beta-carotene, lutein, and vitamin E were linked to the proportion of grazed grass or grass silage in the forage (r = 0.66, 0.69, and 0.51, respectively), unlike the vitamin A content. During grazing, 20 of the 32 terpenoids identified were associated with the proportion of permanent grassland available for grazing or cut. These results show that feeding is an effective way to modify the quality of dairy products, even in the case of bulk tank milk mixtures. Dairy plants could market different milks, which would contain specific compositions.

The recent Haven, Aegean Sea and Sea Empress incidents have highlighted the need for protective measures against the risks posed by the shipping industry to the UK coast. This is particularly the case in the vicinity of environmentally sensitive areas. The principal objectives of this paper are to investigate the state of environmental management of tanker traffic in the UK by putting the geography of shipping into its environmental context. Regional traffic levels, accident rates, oil spills, and their potential consequences upon the environment have been summarised via a risk assessment which also considers coastal sensitivity. An assessment of measures available at international level then sets the scene for a review of marine traffic management schemes in operation around the UK. The state of management and its approaches are also discussed and a number of recommendations put forward during marine conferences in the last twelve months are considered.

Self-similar distribution of oil spills in European coastal waters

2009-01-01

Marine pollution has been highlighted thanks to the advances in detection techniques as well as increasing coverage of catastrophes (e.g. the oil tankers Amoco Cadiz, Exxon Valdez, Erika, and Prestige) and of smaller oil spills from ships. The new satellite based sensors SAR and ASAR and new methods of oil spill detection and analysis coupled with self-similar statistical techniques allow surveys of environmental pollution monitoring large areas of the ocean. We present a statistical analysis of more than 700 SAR images obtained during 1996-2000, also comparing the detected small pollution events with the historical databases of great marine accidents during 1966-2004 in European coastal waters. We show that the statistical distribution of the number of oil spills as a function of their size corresponds to Zipf's law, and that the common small spills are comparable to the large accidents due to the high frequency of the smaller pollution events. Marine pollution from tankers and ships, which has been detected as oil spills between 0.01 and 100 km 2 , follows the marine transit routes. Multi-fractal methods are used to distinguish between natural slicks and spills, in order to estimate the oil spill index in European coastal waters, and in particular, the north-western Mediterranean Sea, which, due to the influence of local winds, shows optimal conditions for oil spill detection.

Bergueiro Lopez, J.R.; Morales Correas, N.; Dominguez Laseca, F.

1993-01-01

In December 1992, the tanker Aegean Sea was shipwrecked at the entrance to a harbor in northwest Spain. The accident was partly due to bad weather conditions and possibly also to the poor condition of the ship, which subsequently broke in two and caught fire. The tanker was carrying 79,000 tons of low-viscosity light oil, of which 40-60% burned. The oil slick coming from the wrecked ship spread westward and northward into nearby bays, impacting 100-200 km of coast with varying degrees of severity. Strong winds and stormy sea conditions at the time of the incident favored evaporation and natural dispersion of much of the spilled oil. Spill response and countermeasures included restriction of fishing zones, manual and mechanical cleaning of beaches and nearby rocks, use of pumps and skimmers to recover oil from water and shore, and stirring oil-penetrated sand to ca 50 cm depth to facilitate oxygenation and ensure degradation of oil traces. About 6,000 m 3 of emulsified oil were collected from the water and another 1,000 m 3 from the shore; 5,000-6,000 tons of unspilled oil was recovered from the tanker. A simulation model estimated that if no burning had occurred, 2/3 of the oil would have dispersed in the sea or evaporated into the air in ca 3 d. Ecological impacts on plankton, benthos, and pelagic and bird communities appears to have been minor or at least relatively localized. Long-term ecological impacts are being studied. However, zones of fish/shellfish breeding were affected, with short-term damages estimated at over $45 million. 9 refs., 5 figs., 1 tab

Shipwreck in the rowing sport community in 1902: reflections on life and death in sport

2016-09-01

Full Text Available People usually start thinking about death when something tragic happens, including in the sport context. At the beginning of 20th century, in South Brazil, four rowers died while they practiced their sport, coming back from an excursion to an island near to Porto Alegre, the capital city of Rio Grande do Sul, where they lived. Following the tragedy, the newspapers published details, both of the tragedy itself, and the ensuing commotion of society, with reflections about life, its fragility and death. This sporting tragedy is a suitable example for trying to understand the way we think about death in sport, given its vast newspaper coverage and the effort to remember the event throughout the 20th century. The interpretation of newspaper sources and reflections on the event will also be considered through the lens of the philosophy of existence of Martin Heidegger. The sources revealed that the shipwreck tragedy made it possible for people to realize that being mortal affects us existentially – that we can never return back to this moment (it is fleeting, it is here and then gone, that we have to make choices that we cannot take back, and that we ourselves are finite beings.

Comparison of Heat Insulations for Cryogenic Tankers Using Analytical and Numerical Analysis

Full Text Available This paper presented a methodology for the design of heat insulations used in cryogenic tankers. This insulation usually comprises a combination of vacuum and perlite or vacuum and superinsulation. Concretely, it is a methodology to obtain the temperatures, heat fluxes, and so forth. Using analytical tools has been established, which is based on the equivalence with an electric circuit, and on numerical tools using finite elements. Results obtained with both methods are then compared. In addition, the influence of the outer finish of the external part, due to the effect of the solar radiation, is analyzed too, and the equations to determine the maximum time available to transport the cryogenic liquid have been established. All these aspects are applied to a specific cryogenic commercial vehicle.

Modeling Residential Water Consumption in Amman: The Role of Intermittency, Storage, and Pricing for Piped and Tanker Water

Directory of Open Access Journals (Sweden)

Christian Klassert

2015-07-01

Full Text Available Jordan faces an archetypal combination of high water scarcity, with a per capita water availability of around 150 m3 per year significantly below the absolute scarcity threshold of 500 m3, and strong population growth, especially due to the Syrian refugee crisis. A transition to more sustainable water consumption patterns will likely require Jordan’s water authorities to rely more strongly on water demand management in the future. We conduct a case study of the effects of pricing policies, using an agent-based model of household water consumption in Jordan’s capital Amman, in order to analyze the distribution of burdens imposed by demand-side policies across society. Amman’s households face highly intermittent piped water supply, leading them to supplement it with water from storage tanks and informal private tanker operators. Using a detailed data set of the distribution of supply durations across Amman, our model can derive the demand for additional tanker water. We find that integrating these different supply sources into our model causes demand-side policies to have strongly heterogeneous effects across districts and income groups. This highlights the importance of a disaggregated perspective on water policy impacts in order to identify and potentially mitigate excessive burdens.

By examining not only the common strategies and structures of shipwreck and captivity narratives, but also direct intertextual connections, it illuminates the shared literary and ideological context of the early modern Iberian empires. The comparison highlights the pleasurable as well as the didactic dimensions of these narratives for early modern writers and readers, thus challenging both nationalist interpretations and those that focus exclusively on their counter-hegemonic potential.

Sulfur and iron accumulation in three marine-archaeological shipwrecks in the Baltic Sea: The Ghost, the Crown and the Sword

Sulfur and iron concentrations in wood from three 17th century shipwrecks in the Baltic Sea, the Ghost wreck, the Crown and the Sword, were obtained by X-ray fluorescence (XRF) scanning. In near anaerobic environments symbiotic microorganisms degrade waterlogged wood, reduce sulfate and promote accumulation of low-valent sulfur compounds, as previously found for the famous wrecks of the Vasa and Mary Rose. Sulfur K-edge X-ray absorption near-edge structure (XANES) analyses of Ghost wreck wood show that organic thiols and disulfides dominate, together with elemental sulfur probably generated by sulfur-oxidizing Beggiatoa bacteria. Iron sulfides were not detected, consistent with the relatively low iron concentration in the wood. In a museum climate with high atmospheric humidity oxidation processes, especially of iron sulfides formed in the presence of corroding iron, may induce post-conservation wood degradation. Subject to more general confirmation by further analyses no severe conservation concerns are expected for the Ghost wreck wood.

In the present study we investigated possible contamination by trace elements due to the oil slick caused by the shipwreck of the Prestige oil tanker, in two species of brown macroalgae (Fucus vesiculosus and Fucus ceranoides) collected from the coastal area most severely affected by the spill (Galicia, NW Spain). The oil slick apparently did not cause significant increases in the concentrations of the trace elements studied, except vanadium. It appears that the magnitude of terrestrial inputs to coastal waters is sufficiently high to mask the inputs of trace elements from the fuel. The observed exception of V suggests that bioaccumulation of this element by the two species of Fucus may be used to indicate exposure to petrochemical products similar to the Prestige fuel. The findings of the study are another example of the importance of the existence of Environmental Specimen Banks for studies of this type

In the present study we investigated possible contamination by trace elements due to the oil slick caused by the shipwreck of the Prestige oil tanker, in two species of brown macroalgae (Fucus vesiculosus and Fucus ceranoides) collected from the coastal area most severely affected by the spill (Galicia, NW Spain). The oil slick apparently did not cause significant increases in the concentrations of the trace elements studied, except vanadium. It appears that the magnitude of terrestrial inputs to coastal waters is sufficiently high to mask the inputs of trace elements from the fuel. The observed exception of V suggests that bioaccumulation of this element by the two species of Fucus may be used to indicate exposure to petrochemical products similar to the Prestige fuel. The findings of the study are another example of the importance of the existence of Environmental Specimen Banks for studies of this type. (author)

Technical Proposal for Loading 3000 Gallon Crude Oil Samples from Field Terminal to Sandia Pressurized Tanker to Support US DOE/DOT Crude Oil Characterization Research Study

Energy Technology Data Exchange (ETDEWEB)

Lord, David; Allen, Raymond

2016-10-01

Sandia National Laboratories is seeking access to crude oil samples for a research project evaluating crude oil combustion properties in large-scale tests at Sandia National Laboratories in Albuquerque, NM. Samples must be collected from a source location and transported to Albuquerque in a tanker that complies with all applicable regulations for transportation of crude oil over public roadways. Moreover, the samples must not gain or lose any components, to include dissolved gases, from the point of loading through the time of combustion at the Sandia testing facility. In order to achieve this, Sandia designed and is currently procuring a custom tanker that utilizes water displacement in order to achieve these performance requirements. The water displacement procedure is modeled after the GPA 2174 standard “Obtaining Liquid Hydrocarbons Samples for Analysis by Gas Chromatography” (GPA 2014) that is used routinely by crude oil analytical laboratories for capturing and testing condensates and “live” crude oils, though it is practiced at the liter scale in most applications. The Sandia testing requires 3,000 gallons of crude. As such, the water displacement method will be upscaled and implemented in a custom tanker. This report describes the loading process for acquiring a ~3,000 gallon crude oil sample from commercial process piping containing single phase liquid crude oil at nominally 50-100 psig. This document contains a general description of the process (Section 2), detailed loading procedure (Section 3) and associated oil testing protocols (Section 4).

Environmental law issues: Offshore oil and gas activities and tanker transportation

International Nuclear Information System (INIS)

Chapman, P.M.

1991-01-01

The environmental law issues that arise from offshore oil/gas activities and petroleum transport are reviewed, focusing on marine oil pollution and especially on the issues surrounding accidental spills. Some observations are offered on the context of these issues, namely on the risks of oil spills, the difficulty of spill response in the ocean and on shorelines, and the possible environmental damage. Environmental control of petroleum operations is discussed with reference to Canadian regulation, the primary source of which is the Oil and Gas Production and Conservation Act. These regulations require developmental approval for offshore operations, formulation of plans for foreseeable spill emergencies, and compensation to those affected by spills, notably those in the fishing industry. Ship-source oil pollution and spill compensation is discussed with reference to international agreements and the Canada Shipping Act. Some problems and trends with oil spill compensation and recovery for environmental damage are noted in such areas as tanker ship standards, cleanup capabilities, and inadequacy of spill penalties and compensation. 18 refs., 1 fig

The I.N.E.R.I.S. (Institut National de l'Environnement Industriel et des Risques) report relative to the consequences of cleaning operations following the pollution bred by the Erika wreck gives the following conclusions: whatever the pollutants are, the carcinogen risks by pulmonary way are negligible for people assigned to the beaches cleaning; the general carcinogen effects, linked to benzopyrene in organism after skin crossing, have been evaluated as negligible; there is a non negligible risk for the embryo-fetal development linked to the benzopyrene skin crossing; It is not possible to tell if the skin cancer risk is or not negligible, because of the uncertainty of the dose effectively absorbed by the skin and the lack of acceptable toxicological references; the risks linked to the volatile organic compounds are negligible; an uncertainty exists on the risks linked to the thiophene family that have not been determined, because of the deficiency of base data. For the second study, whatever the studied scenario, the R.I.V.M. (Riijksinstituut Voor Volksgezondheid en mileuhygiene) Dutch organism report concludes to a risk qualified as acceptable for the voluntary workers and professionals, included the birds cleaners. The risk of skin cancer consecutive to the skin exposure has been characterized with a dose response relationship model coming from previous works of the R.I.V.M. (N.C.)

Transporting US oil imports: The impact of oil spill legislation on the tanker market

International Nuclear Information System (INIS)

1992-06-01

This report looks at the impact of the Oil Pollution Act of 1990 and the developing State oil spill regulations on the tanker and coastal barge markets, and at the implications for the future of the U.S. seaborne petroleum trades. The analysis relied on a dual approach. Because much of the legislation, both State and Federal, is still evolving--particularly with respect to implementing regulations--as yet there can be no definitive assessment of its impact. Consequently a quantitative analysis of fleets, trades, and vessel movements, was complemented by extensive interviews. Discussions have been held with oil companies large and small, shipowners, charterers, insurance companies, classification societies, and a variety of public and private institutions active in the maritime industry. All interviews were conducted in confidence: no individual views are identified in the report. (AT)

This paper describes the current actual conditions on treatment of bilge discharged from engine area and oily drain water from cargo area of tankers. Clean bilge among various bilges discharged from engine area such as vapor drain, fresh water, rainwater, seawater and condensed water is directly dumped into the sea after temporary storage in a clean tank. Oily bilge is produced mainly by mixing of clean bilge and leakage oil from main engines and various auxiliaries. Oily bilge is dumped into the sea under comparative monitoring of the bilge quality with the dumping standard by oil concentration monitoring and control equipment after the primary treatment in a treatment tank and the secondary treatment in a bilge separator. Oily drain water from cargo area contains water ballast for cargo oil tanks, wash water for tanks and lines, and bilge produced in pump room. The oily drain water is dumped under a specific condition. However, water ballast for specific ballast tanks is excluded from the oily drain water. 2 figs.

Unified Tanker Survey and Inspection Regime in Terms of Reducing Psychophysical Strain of the Crew

Directory of Open Access Journals (Sweden)

Toni Bielić

2017-09-01

Full Text Available The paper focuses on analysis of the effect of various surveys and inspections on the psychophysical behaviour of the crew. After analysing the scope and the extent of each regime, the authors identified more than 60% of surveys overlapping each other. Furthermore, the results of the survey conducted among seafarers indicate that the present method of carrying out ship surveys and inspections have a negative effect on the psychophysical condition of the crew. Therefore, a new method of tanker inspections has been proposed in order to reduce the psychophysical strain of the crew. The proposed method would minimise the annual duration of the inspections up to 30% and improve inspection time coordination without compromising quality and safety of the ships.

The study reports for the first time on the heavy metal contamination of the waters surrounding a shipwreck lying on the sea floor. Square wave anodic stripping voltammetry has been used for a survey of the total and dissolved Cd, Pb and Cu contents of the seawater at the site of the sinking of the Nicole M/V (Coastal Adriatic Sea, Italy). Results show that the hulk has a considerable impact as regards all three metals in the bottom water, especially for the particulate fraction concentrations, which increased by factors of ≈ 9 (Cd), ≈ 3 (Pb) and ≈ 5 (Cu). The contaminated plume extended downstream for about 2 miles. Much lower contamination was observed for dissolved bottom concentrations; nevertheless Pb (0.56 ± 0.03 nmol/L) is higher than the Italian legal limits established for 2015 and Cd (0.23 ± 0.03 nmol/L) is very close the limit of Cd will be exceeded if the hulk is not removed.

Report of the Chief Inspector of Marine Accidents into the grounding of the tanker Sea Empress at Milford Haven between 15 and 21 February 1996

International Nuclear Information System (INIS)

1997-01-01

The motor tanker, Sea Empress, was loaded with cargo of 130,018 tonnes of light crude oil when she went aground while entering the harbour at Milford Haven in the United Kingdom on 15th February 1996. About 2,500 tonnes of crude oil were released from damaged cargo tanks when the vessel first grounded. In preparation for a lightening operation, the Sea Empress was first manoeuvred into deeper water then, on 17th February, turned in order to be re-anchored head to wind in the deteriorating weather conditions. Control was lost and the vessel grounded again. Over the next four days the tanker went aground on a number of occasions before being successfully re-floated, taken to a berth within the Haven and the remainder of the cargo discharged. A further 69,300 tonnes of oil were lost to the sea over the period of salvage. The initial grounding and the salvage operation are analysed. The cause of the initial grounding was found to be pilot error. In addition to the bad weather, the lack of tugs of sufficient power and manoeuvrability, and inadequate understanding of the local tidal currents have been identified as the factors which extended the time taken to carry out the salvage operation. Recommendations are made in the light of the findings. (UK)

From tankers to tissues : tracking the degradation and fate of oil discharges in Port Valdez, Alaska

An average of 9 million gallons per day of oil-contaminated ballast water off loaded from tankers are treated at the Alyeska Pipeline Service Company Ballast Water Treatment Facility at the terminus of the Trans-Alaska Pipeline in Port Valdez, Alaska. This paper focuses on the results of 2 Prince William Sound Regional Citizens' Advisory Council monitoring programs which detail changes in the chemical composition of treated ballast water as it moves from tankers through the facility and subsequently traces the effluent hydrocarbons into the receiving environment of Port Valdez. The treatment facility involves gravity separation tanks, dissolved air flotation cells and biological treatment tanks. Effluent containing traces of volatile aromatics, including benzene, toluene, ethylbenzene and xylenes, low levels of oil, saturated hydrocarbons and polycyclic aromatic hydrocarbons is being continuously discharged to Port Valdez. Because of the extremely large average flow rate, low concentrations in the effluent can add up to a significant mass discharge. Samples from the facility were collected on 3 occasions. In March 2004, a limited pilot series of composite samples were collected from the effluent and the effluent to Port Valdez from a sampling port in the Fan/Meter Building. Second-round samples were collected from a wider suite of locations. A BIORATE assay study was completed during September 2004 and January 2005 field programs to measure degradation rates. The largest hydrocarbon pollution sources detected in samples from Port Valdez stations are correlated with an oil spill mishap at the terminal in 1994 and a sheen event in 1997. Apart from these events, concentrations from petrogenic sources are usually near or below the detection limits of the analytic methods used. However, on a routine basis, oil signals attributed to the facility effluent are detectable in mussel tissues at both Alyeska Marine Terminal and Gold Creek stations, and in sediments at Alyeska

Were freak waves involved in the sinking of the Tanker "Prestige"?

Directory of Open Access Journals (Sweden)

A. Lechuga

2006-01-01

Full Text Available This paper deals with the possible involvement of freak, rogue or giant waves in the damage suffered by the Tanker Prestige, which eventually led to its sinking. By reason of their very characteristics, giant waves are hard to record. Their more or less sudden appearance makes them fairly elusive objects, except for the consequences they produce. However, some hints with regard to the probability of their occurrence can be derived from considering how close the maritime weather of the area of interest is to the situation which is optimal for their generation. This paper takes into account the wave field in the area and at the time of the Prestige accident and investigates how near or how far the wave field was to the instability conditions that are favourable to the generation of freak waves in the different approximations. This paper explores mostly the modulation instability which is one of the most common mechanisms to produce freak waves: it leads to the decomposition of an initially homogeneous train of Stokes waves firstly into a series of groups of waves, whose envelope then produces the so-called "solitons", that then collapse in the form of a giant wave. This mechanism mainly occurs in deep waters. Zakharov studied it in 1968 and, independently, Benjamin and Feir analysed it in 1967. This paper proves that the wave field was conspicuously two dimensional with two main wave components travelling in directions almost orthogonal to each other. This means that the wave field was well outside the instability domain. Therefore it is concluded that freak waves were very unlikely generated and it is improbable that they were responsible for the accident.

Full Text Available This study compares the Residual ultimate longitudinal strength – grounding Damage index (R-D diagrams produced by two analysis methods: the ALPS/HULL Intelligent Supersize Finite Element Method (ISFEM and the design formula (modified Paik and Mansour method – used to assess the safety of damaged ships. The comparison includes four types of double-hull oil tankers: Panamax, Aframax, Suezmax and VLCC. The R-D diagrams were calculated for a series of 50 grounding scenarios. The diagrams were efficiently sampled using the Latin Hypercube Sampling (LHS technique and comprehensively analysed based on ship size. Finally, the two methods were compared by statistically analysing the differences between their grounding damage indices and ultimate longitudinal strength predictions. The findings provide a useful example of how to apply the ultimate longitudinal strength analysis method to grounded ships.

Utilisation of VOC in Diesel Engines. Ignition and combustion of VOC released in crude oil tankers

International Nuclear Information System (INIS)

Melhus, Oeyvin

2002-01-01

The emission of VOC (Volatile Organic Compound) is a significant source of hydrocarbon pollution. In Norway, the offshore oil industry represents a major source. This emission represents both an energy loss and an environmental problem. Gas tankers have used boil-off gas from the cargo tanks as fuel for some time. However, for the current VOC project a new fuel injection concept is designed for tankers to take advantage of the energy present in the VOC evaporated from crude oil. The VOC is mixed with inert gas in these tankers, and thus the utilisation of this gas represents new challenges. The VOC project uses the concept of ''Condensate Diesel Process'' with pilot ignition. An experimental study of ignition and combustion of VOC Fuels reported here was initiated by the time it was decided to start a pilot project converting propulsion engines in shuttle tankers to use VOC Fuel. It is an experimental study carried out at the Marine Technology Centre (MTS). The objective was to study ignition and combustion of the chosen process in comparison with an ordinary diesel process. The experimental results have been discussed and compared with theoretical considerations of injection, ignition and combustion. For experiments on combustion, a rapid compression machine ''DyFo'' was redesigned to use VOC Fuel. The DyFo test rig was initially designed to study ignition and early combustion of spark ignited homogeneous gas/air charges. To study the ignition and early combustion of VOC Fuel injected at high pressure and ignited by pilot diesel fuel, a redesign was necessary. An important feature of the DyFo, is the visualisation of the combustion. The advantage of the DyFo test rig over an engine, is its simplicity and controllability. In an engine the visualisation would suffer from combustion deposits disturbing the view through the quartz glasses, making the images more difficult to interpret. The simplicity is on the other side a drawback. Correct thermal conditions inside

Oil spillage in the sea water is a disaster for marine life and humans in the vicinity. The study aimed at investigating health complaints among subjects involved in oil cleanup operations during a spillage from a Greek oil tanker "Tasman Spirit". The project was conducted under the supervision of the Department of Physiology, College of Medicine, King Khalid University Hospital, King Saud University, Riyadh, Saudi Arabia. The study concerned the respiratory and general health complaints in 50 apparently healthy, non-smoking male workers exposed to crude oil during oil cleanup operations. The exposed group was matched with a similar number of male, non-smoking controls. The health complaints were evaluated based on a comprehensive interview. The subjects involved in oil cleanup operations had significantly higher rates of health complaints including cough (38%), runny nose (36%), eye irritation/redness (32%), sore throat (28%), headache (28%), nausea (24%) and general illness (18%), compared to their matched controls. Air pollution due to crude oil spillage into sea water may cause respiratory and general health complaints in workers involved in oil cleanup operations.

Atlantic Canada : recipe for ruin, loophole in Canadian tanker laws questioned

International Nuclear Information System (INIS)

Reid, W.

2001-01-01

During a storm in December 2000, the captain of a leaking supertanker named the Eastern Power requested permission to dock his 339-metre ship at Come by Chance in Newfoundland. The request was denied by Transport Canada and the barge carrying 1.9 million barrels of oil had to ride out the storm just outside Canada's 200-mile limit. The concern was that the hull might split and spill huge amounts of oil. The Eastern Power has only one hull and is twice the age that the Prevention of Pollution from Ships considers reasonable for the lifespan of a vessel. Tankers built after 1993 are required to have an inside and an outside frame in order to enter Canadian waters. Those that are not double hulled and built before 1993 will be phased out by 2015. The spokesman for Transport Canada explained that the concern regarding the Eastern Power was for the Canadian environment. Owners are responsible for making sure that their ships do not risk our environment. An added precaution requires that all ships radio the Canadian Coast Guard 24 hours before reaching the 200-mile limit to report on their course, destination and seaworthiness. While Transport Canada makes the ultimate decision on entry, it shares the information with the Department of National Defense, Environment Canada and the coast guard. In this case, the crew of the Eastern Power was able to pump cargo into a safer tank and repaired the rupture. It was then given permission to dock at Come By Chance, but it instead headed for the Caribbean. Newfoundland is still recovering from the collapse of the cod fishery and is trying to build an eco-tourism industry given that its Atlantic offshore is a marine ecological treasure. Environmentalists view some of the present marine laws, or lack of laws, as a gateway to a disaster which could wipe out some water fowl species and further reduce fish stocks. 1 fig

Very serious air pollution was brought about by the fire in oil fields at the end of February, 1991 after the Middle East Gulf War had come to an end. The present report explained the investigation result of actual air pollution situation obtained through measurement by implements mounted on board of the Japan Violet, crude oil tanker which made navigation in the Persian Gulf from 17 to 29 August, 1991. Non-marine salinity sulfate and nitrate in the dust particulates which are representative substances for the air pollution were 10.5 and 3.7[mu]g/m[sup 3], respectively in mean atmospheric content. Such a content level was nearly equal to that in the air-polluted land area and very high for the offshore air. It is judged to be resultant from the particulate formation of non-marine salinity salt from SO2 and NOx which were abundantly emitted, dispersed in the Persian Gulf and oxidized. However as a result of the neutralization by Ca contained in high content sanddust in the atmosphere of the Persian Golf, the acidity of sanddust was not so high. 7 refs., 8 figs., 1 tab.

Application of Bayesian Belief networks to the human reliability analysis of an oil tanker operation focusing on collision accidents

International Nuclear Information System (INIS)

Martins, Marcelo Ramos; Maturana, Marcos Coelho

2013-01-01

During the last three decades, several techniques have been developed for the quantitative study of human reliability. In the 1980s, techniques were developed to model systems by means of binary trees, which did not allow for the representation of the context in which human actions occur. Thus, these techniques cannot model the representation of individuals, their interrelationships, and the dynamics of a system. These issues make the improvement of methods for Human Reliability Analysis (HRA) a pressing need. To eliminate or at least attenuate these limitations, some authors have proposed modeling systems using Bayesian Belief Networks (BBNs). The application of these tools is expected to address many of the deficiencies in current approaches to modeling human actions with binary trees. This paper presents a methodology based on BBN for analyzing human reliability and applies this method to the operation of an oil tanker, focusing on the risk of collision accidents. The obtained model was used to determine the most likely sequence of hazardous events and thus isolate critical activities in the operation of the ship to study Internal Factors (IFs), Skills, and Management and Organizational Factors (MOFs) that should receive more attention for risk reduction.

Microbial stowaways: Addressing oil spill impacts and the artificial reef effect on deep-sea microbiomes

Shipwrecks enhance macro-biological diversity in the deep ocean, but, to date, studies have not explored the reef effect on deep-sea microbiological diversity. This is an important concept to address in a restoration framework, as microbial biogeochemical function impacts recruitment and adhesion of higher trophic levels on artificial reefs. In addition, microbial biofilms influence the preservation of shipwrecks through biologically mediated corrosion. Oil and gas-related activities have potential to disrupt the base of the reef trophic web; therefore, bacterial diversity and gene function at six shipwrecks (3 steel-hulled; 3 wood-hulled) in the northern Gulf of Mexico was investigated as part of the GOM-SCHEMA (Shipwreck Corrosion, Hydrocarbon Exposure, Microbiology, and Archaeology) project. Sites were selected based on proximity to the Deepwater Horizon spill's subsurface plume, depth, hull type, and existing archaeological data. Classification of taxa in sediments adjacent to and at distance from wrecks, in water, and on experimental steel coupons was used to evaluate how the presence of shipwrecks and spill contaminants in the deep biosphere influenced diversity. At all sites, and in all sample types, Proteobacteria were most abundant. Biodiversity was highest in surface sediments and in coupon biofilms adjacent to two steel-hulled wrecks in the study (Halo and Anona) and decreased with sediment depth and distance from the wrecks. Sequences associated with the iron oxidizing Mariprofundus genus were elevated at steel-hulled sites, indicating wreck-specific environmental selection. Despite evidence of the reef effect on microbiomes, bacterial composition was structured primarily by proximity to the spill and secondarily by hull material at all sites. This study provides the first evidence of an artificial reef effect on deep-sea microbial communities and suggests that biodiversity and function of primary colonizers of shipwrecks may be impacted by the spill.

Creating Student Engagement Through Immersion: Exploring the MT6 Shipwreck in Puget Sound via Submersible, Using a Team Challenge Format

Educational literature has many stories describing the "aha" moment that teachers are privileged to observe: a student who suddenly grasps a concept (ding!), dives into an activity (whee!) or works tirelessly to complete a complicated project (wow!). Designing moments like these for students can be one of the great joys of teaching. Experiencing such a moment can have a lasting impact on student engagement and motivation, and is the underlying rationale for the importance of creating a wide array of outreach efforts, from field work to telepresence activities.During the spring of 2015, OceanGate Foundation and Seattle Central College partnered on a pilot program to design a program that had this kind of impact and created the Open The Oceans Challenge. Student teams responded to our Request for Proposal (RFP), which was centered around the exploration of a shipwreck in 150 meters of water just off the Seattle waterfront, the MT-6. Students spent a significant amount of time crafting their proposals and reported that they enjoyed the process of writing the proposal as a team. The two winning teams accompanied us on a series of submersible dives performed by OceanGate, Inc. and worked up the results afterward. In addition to researching the MT-6 wreck and documenting what they found, students were able to do basic observational research on the wreck, providing sonar and photographic data that will help form the basis of future expeditions to this site.We report on lessons learned from this pilot — the impact for the small set of students involved in this project was profound, but how can we expand the reach of such activities? Results from this experience suggest that providing a highly engaging topic and expedition may not be enough to inspire an "aha" moment that creates lasting engagement; the scaffolding and mentorship that surrounds a rich experience is also critical.

The Overview Of Water Pollution In The World

Directory of Open Access Journals (Sweden)

Van Vang Le

2017-08-01

Full Text Available Water is a precious resource but not everyone is aware of it. More than 1 billion people are missing about 20 to 50 liters of clean water each day to cater for basic needs such as eating and bathing. The phenomenon of oil exploration ocean shipping and petroleum-contaminated wastes is one of the causes of water pollution. It is estimated that about 1 billion tons of oil are transported by sea each year. Part of this volume about 0.1 to 0.3 is thrown into the sea in a relatively legal way the washing of oil tankers with seawater. The shipwreck is relatively regular disposal of lubricant or accidental dropping gasoline. The permeation rate of petroleum is seven times that of water which will cause the groundwater to become contaminated. About 1.6 million tons of hydrocarbons are discharged by rivers of industrialized nations. From the above causes we see that human consciousness is the main cause of pollution of water environment. Resources are not endless with the exploitation of an indiscriminate wing rampant run for market economy benefits without the appropriate treatment the water pollution is a certain matter. The importance is inevitable if people are unaware of the importance of water for life in the near future the resources will be exhausted.

Energy efficiency estimation of a steam powered LNG tanker using normal operating data

Directory of Open Access Journals (Sweden)

Sinha Rajendra Prasad

2016-01-01

Full Text Available A ship’s energy efficiency performance is generally estimated by conducting special sea trials of few hours under very controlled environmental conditions of calm sea, standard draft and optimum trim. This indicator is then used as the benchmark for future reference of the ship’s Energy Efficiency Performance (EEP. In practice, however, for greater part of operating life the ship operates in conditions which are far removed from original sea trial conditions and therefore comparing energy performance with benchmark performance indicator is not truly valid. In such situations a higher fuel consumption reading from the ship fuel meter may not be a true indicator of poor machinery performance or dirty underwater hull. Most likely, the reasons for higher fuel consumption may lie in factors other than the condition of hull and machinery, such as head wind, current, low load operations or incorrect trim [1]. Thus a better and more accurate approach to determine energy efficiency of the ship attributable only to main machinery and underwater hull condition will be to filter out the influence of all spurious and non-standard operating conditions from the ship’s fuel consumption [2]. The author in this paper identifies parameters of a suitable filter to be used on the daily report data of a typical LNG tanker of 33000 kW shaft power to remove effects of spurious and non-standard ship operations on its fuel consumption. The filtered daily report data has been then used to estimate actual fuel efficiency of the ship and compared with the sea trials benchmark performance. Results obtained using data filter show closer agreement with the benchmark EEP than obtained from the monthly mini trials . The data filtering method proposed in this paper has the advantage of using the actual operational data of the ship and thus saving cost of conducting special sea trials to estimate ship EEP. The agreement between estimated results and special sea trials EEP is

As a part of the WE-NET project, the tanker for liquid hydrogen transport was studied. In fiscal 1996, some experiments and numerical analyses were proposed which are necessary to solve technological issues extracted in fiscal 1995 for heat insulation structure. The issue was roughly classified into vacuum and non-vacuum insulation, and their basic functions and required performance were arranged. Boil-off rate of 0.2-0.4%/d was targeted. The insulation system which applies polyurethane form (PUF) to tank surfaces and injects atmospheric N2 gas into the surrounding hold space, could achieve the targeted insulation performance by PUF of 1m in thickness. The system of vacuum panel insulation and atmospheric N2 gas injection into a hold space required the panel of 500mm in thickness because of the large effect of metallic outer panel material. The system of vacuum hold and PUF panels was faced with the essential issue for realizing and maintaining vacuum hold. The super insulation system featured by layered insulation materials and vacuum layer spaces was also strongly affected by degree of vacuum. 23 figs., 8 tabs.

Growth and condition of juvenile sole (Solea solea L. as indicators of habitat quality in coastal and estuarine nurseries in the Bay of Biscay with a focus on sites exposed to Erika oil spill

Directory of Open Access Journals (Sweden)

Camille Gilliers

2006-06-01

Full Text Available Indicators of growth and condition were used to compare the habitat quality of nurseries of juvenile sole (Solea solea L. in the Bay of Biscay, based on one survey in 2000. The four biological indicators are poorly correlated with each other, suggesting that no single measure may give an adequate description of fish health and of its habitat’s quality. Growth indicators showed significant differences between northern and southern areas. Juveniles from the two southernmost nurseries, the Gironde estuary and the Pertuis Antioche, displayed significant lower otolith increment widths and mean sizes. These differences were inversely related to water temperature and unrelated to genetic or age differences, and are unlikely to be due to limiting trophic conditions in the nurseries. Hence, they may be considered in terms of differences in habitat quality and potential anthropogenic impacts. Condition indices do not show this north-south pattern but highlight low condition values in the Pertuis Antioche. Short-term and fluctuating biochemical indicators such as RNA/DNA ratios appeared to be unreliable over a long-term study, while morphometric indices seemed to be relevant, complementary indicators as they integrate the whole juvenile life-history of sole in the nurseries. The growth and condition indices of juveniles in September 2000 from nursery grounds exposed to the Erika oil spill in December 1999 were relatively high. These results lead us to suggest that there was no obvious impact of this event on the health of juvenile sole and on the quality of the exposed nursery grounds a few months after the event.

The oil spill modelling in the Sea of Japan: application to the tanker 'Nakhodka' 1997 incident

1998-01-01

In January 1997 the Russian tanker 'NAKHODKA' spilled into the Sea of Japan about 5000 tons of heavy fuel oil type C. Most of it reached the coast of Japan and damaged the environment. This incident forced the development of the operational system for the prediction of oil spills in the Sea of Japan. As a part of this system the model for oil spill modelling is presented. The modelled climatological sea currents were used in these simulators, generated by the three-dimensional primitive ocean circulation model with 10-minute horizontal resolution and 19 vertical levels. The model was forced by climatological atmospheric winds and heat fluxes. The wind currents in the upper sea layer were estimated by the wind data of ECMWF with 6 hours time and 0.5625-degree spatial resolution. The vertical structure of the total currents was interpolated using both wind driven currents and the climatological model currents data at the model levels. The oil spill was modelled with the particle tracking techniques. The model included the advection by currents, random diffusion, the buoyancy effect and the parameterisation of oil evaporation, biodegradation and beaching. For the deep sea the parameterisation of diffusion depends from the stratification, taken from the ocean circulation model output. The results demonstrated the defined relation with the observed propagation of the oil along the coast of Japan and highlighted the most important directions for the model development. The main is the realisation of the model for the real-time simulations and forecasts of the ocean currents with the fine resolution in the upper layer of the Sea of Japan. (author)

Characterization of phytoplankton biodiversity in tropical shipwrecks off the coast of Pernambuco, Brazil Caracterização da biodiversidade do fitoplâncton em naufrágios tropicais da costa de Pernambuco, Brasil

Full Text Available The phytoplankton community was studied around two artificial reefs (shipwrecks Servemar-X and Servemar-I, located off the coast of Pernambuco, northeastern Brazil, aiming to identify and thus, better describe these environments. Water samples were collected with Nansen bottle at three depths (surface, mid-column and bottom for chlorophyll a analysis and salinity; temperature and water transparency were also measured. To collect phytoplankton samples, a diver using SCUBA equipment carried out phytoplankton hauls with a 20 µm net around the shipwrecks, about 1.5 m from the bottom for approximatly 3 minutes. Chlorophyll a concentrations at the bottom varied between 0.61 and 5.97 mg.m-3, with an average that indicates a mesotrophic environment. Temperature and salinity registered small seasonal variation, while water transparency showed a seasonal spatial pattern positively related to Chl-a rates. As regards the phytoplankton community, diatoms were the most representative group in the samples, followed by dinoflagellates, and among the species, the cyanobacteria Trichodesmium thiebautii Gomont ex Gomont prevailed quantitatively. The ecological importance of these ecosystems was confirmed by the high diversity and evenness indexes, with the influence of coastal waters playing an essential role in phytoplankton structure and diversity.A comunidade fitoplanctônica foi estudada nas adjacências de dois recifes artificiais (naufrágios Servemar-X e Servemar-I, na costa de Pernambuco, nordeste do Brasil, com o intuito de identificá-la e melhor caracterizar esses ambientes.

Experiment in democracy: The citizen oversight council as a means of mitigating environmental impacts of terminal and tanker operations

International Nuclear Information System (INIS)

Ginsburg, P.; Sterling, S.; Gottehrer, S.

1993-01-01

In 1987, a handful of people from the small fishing community of Cordova, Alaska, coalesced around concern over the risks of oil-related pollution and oil spills in Prince William Sound posed by the trans-Alaska pipeline terminal and tanker operations in neighboring Valdez. The Cordova group sent an emissary to Alyeska Pipeline Service Company, which operates the Valdez Marine Terminal on behalf of its seven oil company owners. The emissary asked Alyeska to consider forming a citizen group to advise Alyeska on environmental issues of local or regional concern. Alyeska listened but rejected the idea. In March 1989, the Exxon Valdez ran aground on Bligh Reef. Alyeska's owners, acting principally at the behest of majority owner, British Petroleum, soon effected sweeping change in Alyeska's management. The change in management, with Jim Hermiller as president, produced a change in Alyeska's attitude toward the citizen advisory group proposal, and not long afterward Alyeska formed the Alyeska Citizen Advisory Committee. Over the next year that group evolved into what is now called the Prince William Sound Regional Citizens' Advisory Council, or RCAC. The Prince William Sound Regional Citizens' Advisory Council is a national experiment in providing citizens a voice in corporate decisions that affect them and their communities. This paper recounts the story of RCAC's formation and evolution, the group's mission under both federal law and its contract with Alyeska, and the hallmarks of its achievements and challenges to date

Application of FTIR spectroscopy to the characterization of archeological wood.

Traoré, Mohamed; Kaal, Joeri; Martínez Cortizas, Antonio

2016-01-15

Two archeological wood samples were studied by attenuated total reflectance Fourier transform infrared (FTIR-ATR) spectroscopy. They originate from a shipwreck in Ribadeo Bay in the northwest of Spain and from a beam wood of an old nave of the Cathedral of Segovia in the central Spain. Principal component analysis was applied to the transposed data matrix (samples as columns and spectral bands as rows) of 43 recorded spectra (18 in the shipwreck and 25 in the beam wood). The results showed differences between the two samples, with a larger proportion of carbohydrates and smaller proportion of lignin in the beam than in the shipwreck wood. Within the beam wood, lignin content was significantly lower in the recent than the old tree rings (P=0.005). These variations can be attributed to species differences between the two woods (oak and pine respectively), with a mixture of guaiacyl and syringyl in hardwood lignin, whereas softwood lignin consists almost exclusively of guaiacyl moieties. The influence of environmental conditions on the FTIR fingerprint was probably reflected by enhanced oxidation of lignin in aerated conditions (beam wood) and hydrolysis of carbohydrates in submerged-anoxic conditions (shipwreck wood). Molecular characterization by analytical pyrolysis of selected samples from each wood type confirmed the interpretation of the mechanisms behind the variability in wood composition obtained by the FTIR-ATR.

The sinking of the RMS Titanic is one of the most infamous shipwrecks in history. On April 15, 1912, during her maiden voyage, the Titanic sank after colliding with an iceberg, killing 1502 out of 2224 passengers and crew. This sensational tragedy shocked the international community and led to better safety regulations for ships. One of the reasons that the shipwreck led to such loss of life was that there were not enough lifeboats for the passengers and crew. Although there was some el...

Zinc concentrations in the water column influenced by the oil spill in the vicinity of the Prestige shipwreck; Concentraciones de zinc en la columna de agua influida por el derrame de fuel en los alrededores a la zona de naufragio del Prestige

Sixteen days after the Prestige tanker sank in the Northeast Atlantic (42 degrees 11 minutes North, 12 degrees 02 minutes West), a sampling campaign in the neighbouring water column was carried out in order to evaluate the possibility of zinc contamination due to the oil spill. Samples were taken in the water column (0-190 m) and in bottom waters -in the vicinity of the bow and stern- where the tanker lies (3520-3820 m). Total zinc concentrations found ranged from 14 to 571 nM, which are from one to two orders of magnitude higher than typical concentrations in these waters (0.2 - 3.2 nM). Therefore, a contamination by this metal, contained in the oil spilt from the tanks of the sunken ship, was detected. Zinc was also found to be a good tracer to detect the presence of fuel in those areas free of patches. [Spanish] Dieciseis dias despues del hundimiento del petrolero Prestige en el Atlantico Noreste (zona 42 grados 11 minutos Norte, 12 grados 02 minutos Este) se llevo a cabo una campana de muestreo en la columna de agua adyacente para evaluar la posible contaminacion de zinc debido al fuel derramado al agua. Para ello se tomaron muestras en la columna de agua (0-190m) y en el fondo marino -en las proximidades de la proa y la popa- donde yace el petrolero (3530-3820 m). Las concentraciones totales de zinc obtenidas oscilaron entre 14 y 571 nM, esto es, de uno a dos ordenes de magnitud superiores a las normales en esas aguas (0.2-3.2 nM). Se detecta, pues, una contaminacion por este metal contenido en el fuel vertido procedente de los tanques del buque hundido. El zinc resulta, ademas, un buen trazador para detectar la presencia de fuel en zonas limpias de manchas.

Chronic kidney disease (CKD) is a major public health problem in India. The CKD registry of India has been formed to understand the epidemiology of CKD in India. Due to health economics in India, the majority of CKD-affected patients cannot afford renal replacement therapy (RRT) services. There is an unmet need to improve the awareness of kidney disease in India, and the focus should be on prevention and early detection of CKD by screening high risk populations. The Tamilnad Kidney Research (TANKER) Foundation is a charitable trust established in 1993 with the aim to improve awareness and provide quality affordable treatment to underprivileged patients. TANKER is supported by contributions from well-wishers. It has three arms: i) treatment arm, ii) research arm, and iii) awareness and screening arm. TANKER Foundation offers free and subsidized dialysis twice weekly to 227 underprivileged patients. TANKER dialysis has been supported by state government funding schemes. TANKER actively supports and conducts research in nephrology. More than 100,000 people have benefitted from TANKER's kidney awareness programs. The screening programs have provided for early detection of CKD in both urban and rural areas. TANKER award functions are held annually to recognize research and exemplary service to society. The TANKER Foundation can be used as a model for developing countries to address the unmet needs in CKD management.

Managing an invasive corallimorph at Palmyra Atoll National Wildlife Refuge, Line Islands, Central Pacific

2018-01-01

In 2007, a phase shift from corals to corallimorpharians (CM) centered around a shipwreck was documented at Palmyra Atoll, Line Islands. Subsequent surveys revealed CM to be overgrowing the reef benthos, including corals and coralline algae, potentially placing coral ecosystems in the atoll at risk. This prompted the U.S. Fish and Wildlife Service, the lead management agency of the atoll, to remove the shipwreck. Subsequent surveys showed reductions in CM around the ship impact site. We explain patterns of spread of the CM in terms of both life history and local currents and show with a pilot study that pulverized bleach may be an effective tool to eradicate CM on a local scale. If applied strategically, particularly in heavily infested (> 66% cover) areas, active intervention such as this could be an effective management tool to reduce CM impact on localized areas and decrease colonization rate of remaining reefs. This is the first documentation of the response of an invasive cnidarian to shipwreck removal. While this was a singular event in Palmyra, the spatial and temporal patterns of this invasion and the eradications lessons described herein, are useful for anticipating and controlling similar situations elsewhere.

Predicted loads, such as crew, cargo, and structure have been applied as main inputs during ship design and analysis. However, unexpected events on the sea has high possibility to deliver remarkable losses for ship, industry, and environment. Previous oil spill incident by the Exxon Valdez in Alaska is the perfect example which an environmental damage and industry loss are initiated by an impact phenomenon on the ship, i.e. grounding. Even though hull arrangement has adopted double hull system, grounding may threaten ship safety in various scenarios. This situation pushes society to demand sustainable investigation for impact phenomena on water transportation mode to update understanding in the phenomenon and ensure structural safety during ship operation. This work aimed to study structural behaviour of chemical tanker as a marine structure under impact, namely ship grounding. Bottom raking case was considered to be calculated by virtual experiment. The study was performed using nonlinear finite element (FE) method and an idealised geometry of seabed rock would be deployed to be hard obstruction. Observation on the selected crashworthiness criteria, i.e. internal energy and crushing force indicated that as advanced penetration occurred on the ship structure, the absorbed strain energy continued to increase, while major fluctuation appeared during the initial contact between obstruction and ship happened. Damage extent of several structural members during the crushing process was shown, which concluded that the bottom plating had the largest severity in forms of tearing mode among of all members on the bottom structure.

The internal surfaces of crude petroleum tankers are subjected to corrosive environments, therefore it is of great importance to research coatings for the protection of those structures. Ceramic materials generally exhibit characteristic chemical inertness and are shown as material option for this application. In this study alumina-titania ceramic composites have been produced and reinforced with yttria. These composites were produced by thermo-mechanical process, sintered at 1350 ° C for 24 hours, and left to cool down in the oven. The structural and microstructural characterization of the sintered material was tested by X-ray diffraction and scanning electron microscopy. And its mechanical property was studied by Vickers microhardness test. After this characterization, the samples underwent a stability test where they were immersed in crude oil at room temperature for 60 days, during which were periodically subjected to tests related to stability, which was found found that the material was free from cracks, fissures or fractures, presenting for these reasons characteristics of inertia when subjected to crude oil environment.

Due to the sheer size and capacity of the tanker and the properties of cargo transported in the tank, hazmat tanker accidents are more disastrous than other types of vehicle accidents. The aim of this study was to provide a current survey on the situation of accidents involving tankers transporting hazardous materials in China. Detailed descriptions of 708 tanker accidents associated with hazmat transportation in China from 2004 to 2011 were analyzed to identify causes, location, types, time of occurrence, hazard class for materials involved, consequences, and the corresponding probability. Hazmat tanker accidents mainly occurred in eastern (38.1%) and southwest China (12.3%). The most frequent hazmat tanker accidents involved classes 2, 3, and 8. The predominant accident types were rollover (29.10%), run-off-the-road (16.67%), and rear-end collisions (13.28%), with a high likelihood of a large spill occurring. About 55.93% of the accidents occurred on freeways and class 1 roads, with the spill percentage reaching 75.00% and the proportion of spills that occurred in the total accidents amounting to 77.82%, of which 61.72% are considered large spills. The month with the highest accident probability was July (12.29%), and most crashes occurred during the early morning (4:00-6:00 a.m.) and midday (10:00 a.m.-12:00 p.m.) hours, 19.63% versus 16.10%. Human-related errors (73.8%) and vehicle-related defects (19.6%) were the primary reasons for hazmat tanker crashes. The most common outcomes of a hazmat tanker accident was a spill without further events (55.51%), followed by a release with fire (7.77%), and release with an explosion (2.54%). The safety situation of China's hazmat tanker transportation is grim. Such accidents not only have high spill percentages and consistently large spills but they can also cause serious consequences, such as fires and explosions.

Technology development is being conducted for construction of the long distance transportation tanker of large quantity liquid hydrogen. In fiscal 1997, test pieces of thermal insulating materials to be planned for fiscal 1998 were designed and studied. The purpose of the test is to confirm thermal insulating performance and behaviors of each material under the temperature of liquid hydrogen. The inside of the outer tank of the experimental equipment was held at vacuum of 10{sup -6} to 10{sup -7} Torr to exclude thermal convection effects and evaluate only heat coming from heater through the test piece. The heat from the heater at the lower part of the test piece is through the test piece and makes the liquid hydrogen of the upper tank evaporate. Thermal conductivity of the test piece is calculated from the evaporation quantity.

Non-native molluscan colonizers on deliberately placed shipwrecks in the Florida Keys, with description of a new species of potentially invasive worm-snail (Gastropoda: Vermetidae

Directory of Open Access Journals (Sweden)

Rüdiger Bieler

2017-04-01

Full Text Available Artificial reefs created by deliberately sinking ships off the coast of the Florida Keys island chain are providing new habitat for marine invertebrates. This newly developing fouling community includes the previously reported invasive orange tube coral Tubastraea coccinea and the non-native giant foam oyster Hyotissa hyotis. New SCUBA-based surveys involving five shipwrecks spanning the upper, middle, and lower Florida Keys, show T. coccinea now also established in the lower Keys and H. hyotis likewise extending to new sites. Two additional mollusks found on the artificial reefs, the amathinid gastropod Cyclothyca pacei and gryphaeid oyster Hyotissa mcgintyi, the latter also common in the natural reef areas, are discussed as potentially non-native. A new species of sessile, suspension-feeding, worm-snail, Thylacodes vandyensis Bieler, Rawlings & Collins n. sp. (Vermetidae, is described from the wreck of the USNS Vandenberg off Key West and discussed as potentially invasive. This new species is compared morphologically and by DNA barcode markers to other known members of the genus, and may be a recent arrival from the Pacific Ocean. Thylacodes vandyensis is polychromatic, with individuals varying in both overall head-foot coloration and mantle margin color pattern. Females brood stalked egg capsules attached to their shell within the confines of their mantle cavity, and give rise to crawl-away juveniles. Such direct-developing species have the demonstrated capacity for colonizing habitats isolated far from their native ranges and establishing rapidly growing founder populations. Vermetid gastropods are common components of the marine fouling community in warm temperate and tropical waters and, as such, have been tagged as potentially invasive or with a high potential to be invasive in the Pacific Ocean. As vermetids can influence coral growth/composition in the Pacific and have been reported serving as intermediate hosts for blood flukes of

Method and system for offshore production of liquefied natural gas; Fremgangsmaate og system for fremstilling av flytendegjort naturgass til havs

Energy Technology Data Exchange (ETDEWEB)

Breivik, K.G.; Fredheim, A.O.; Paurola, P.

1997-01-13

The invention concerns an method and system for offshore production of liquefied natural gas (LNG), wherein natural gas is supplied from an underground source to a subsea production plant. The gas is transferred under a high pressure directly from the production plant to an LNG tanker through a pipeline underwater causing the temperature of the high pressure gas to be lowered to a desired low temperature. This gas is supplied to a conversion plant provided on the LNG tanker and arranged for converting at least a part of the gas to liquid form, and the liquefied gas is transferred to storage tanks on board the same. When the storage tanks are filled up, the pipeline is disconnected from the LNG tanker and connected to another similar tanker. The pipeline is permanently connected to a submerged buoy which is arranged for introduction and releasable securement in a submerged downwardly open receiving space in the tanker, and which is provided with a swivel unit for transfer of gas under a high pressure. 3 figs.

Introduction to the marine transportation of bulk LNG and the design of LNG carriers

Energy Technology Data Exchange (ETDEWEB)

Wilson, J J

1974-03-01

The marine transportation of bulk LNG is expected to expand considerably in the near future to help supply the continuous and growing demand for energy predicted for the U.S., Japan, and Western Europe. The number of new LNG tankers required to provide for these markets is estimated to be at least 50 new 4.4 million ft/sup 3/ tankers by 1980. The standard LNG tanker size is expected to increase to 7.06 million ft/sup 3/ within 5 yr. In selecting a particular tanker system, prospective ship-owners may have to consider such factors as national and international subsidies, shipyard limitations, and the trend to build certain specialized tanker components in areas other than in the shipyard. This work separation could help reduce tanker construction cost and time--especially important when several ships are to be constructed. Containment techniques available for construction of the cargo tanks include the self-supporting and the integrated designs, with the most economical provided by systems carrying LNG as a bulk cargo slightly subcooled below its boiling temperature at near-atmospheric pressure. All designs must fulfill the requirements for maintaining the approved temperature over the entire hull structure, preventing excess heat leaks into the cargo, providing tight liquid containment of the cargo, controlling the conditions inside and outside, and providing the proper facilities for safe loading and unloading. Materials of construction range from a combination of various grades of mild steel for the hull to the highest grades of aluminum alloys and nickel steels for the tank areas. Insulation includes polyurethane foam, silicon-coated perlite, and balsa wood used with fiberglass, polyurethane foam, or mineral wool. The insulation materials and arrangement must be waterproof, fire-resistant, and suitable to withstand the forces imposed on them. Finally, the tankers must include the proper equipment for LNG handling, pumping, and boiloff control.

Fieldwork Methodology in South American Maritime Archaeology: A Critical Review

Science.gov (United States)

Argüeso, Amaru; Ciarlo, Nicolás C.

2017-12-01

In archaeology, data obtained from the analysis of material evidence (i.e., the archaeological record) from extensive excavations have been a significant means for the ultimate development of interpretations about human life in the past. Therefore, the methodological procedures and tools employed during fieldwork are of crucial importance due to their effect on the information likely to be recovered. In the case of maritime archaeology, the development of rigorous methods and techniques allowed for reaching outcomes as solid as those from the work performed on land. These improvements constituted one of the principal supports—if not, the most important pillar—for its acceptance as a scientific field of study. Over time, the growing diversity of sites under study (e.g., shipwrecks, ports, dockyards, and prehistoric settlements) and the underwater environments encountered made it clear that there was a need for the application of specific methodological criteria, in accordance with the particularities of the sites and of each study (e.g., the research aims and the available resources). This article presents some ideas concerning the methodologies used in South American investigations that have exhibited a strong emphasis on the analysis of historical shipwrecks (the sixteenth to twentieth centuries). Based on a state-of-the-knowledge review of these research projects, in particular where excavations were conducted, the article focuses on the details of the main strategies adopted and results achieved. The ideas proposed in this article can be useful as a starting point for future activities of surveying, recording, and excavating shipwrecks.

Black reefs: iron-induced phase shifts on coral reefs.

2012-03-01

The Line Islands are calcium carbonate coral reef platforms located in iron-poor regions of the central Pacific. Natural terrestrial run-off of iron is non-existent and aerial deposition is extremely low. However, a number of ship groundings have occurred on these atolls. The reefs surrounding the shipwreck debris are characterized by high benthic cover of turf algae, macroalgae, cyanobacterial mats and corallimorphs, as well as particulate-laden, cloudy water. These sites also have very low coral and crustose coralline algal cover and are call black reefs because of the dark-colored benthic community and reduced clarity of the overlying water column. Here we use a combination of benthic surveys, chemistry, metagenomics and microcosms to investigate if and how shipwrecks initiate and maintain black reefs. Comparative surveys show that the live coral cover was reduced from 40 to 60% to reefs on Millennium, Tabuaeran and Kingman. These three sites are relatively large (>0.75 km(2)). The phase shift occurs rapidly; the Kingman black reef formed within 3 years of the ship grounding. Iron concentrations in algae tissue from the Millennium black reef site were six times higher than in algae collected from reference sites. Metagenomic sequencing of the Millennium Atoll black reef-associated microbial community was enriched in iron-associated virulence genes and known pathogens. Microcosm experiments showed that corals were killed by black reef rubble through microbial activity. Together these results demonstrate that shipwrecks and their associated iron pose significant threats to coral reefs in iron-limited regions.

High freight rates hinder oil markets' return to equilibrium

International Nuclear Information System (INIS)

Anon

2005-01-01

Hurricane damage to refineries in the US has created shortages of refined products there, boosting imports and sending freight rates across the Atlantic to record levels. The situation was made worse for a time by a strike at France's main oil terminals in the Mediterranean, which prevented some oil tankers from being rapidly redeployed to routes across the Atlantic. Worldscale (WS) rates for routes from the UK and Europe to the US Atlantic and Gulf Coasts rose well above WS500 for clean tonnage during October. High rates were nevertheless not simply confined to product tankers crossing the Atlantic. Rates for crude tankers to the US have also risen, and tightness has begun to appear in some other markets as well. The net result has been to slow down the movement of oil from regions of surplus to those of scarcity, depressing prices in the former and keeping them at high levels in the latter. Atlantic tanker markets look like remaining tight for the rest of the year and perhaps beyond. (author)

Mechanical fasteners used in historical Siberian shipbuilding: perspectives for metallurgical analysis

Science.gov (United States)

Goncharov, A. E.; Mednikov, D. M.; Karelin, N. M.; Nasyrov, I. R.

2017-10-01

Recent discoveries of shipwrecked vessels in the northern reaches of the river Yenisei led to a number of questions concerning the history of shipbuilding in Siberia and the technical features of the first vessels of the industrial era to navigate the Northern Sea Route and the Yenisei. One of these questions addresses the features of mechanical fasteners used in the construction of the Siberian vessels. The answer to this question may provide information on how the first vessels, constructed in Siberia during the 1870’s, were able to sail the high seas of the Arctic Ocean and reach European ports. In this paper, we provide a description of iron mechanical fasteners obtained from one shipwrecked vessel and discuss on the perspectives of a metallurgical analysis This research has been funded by a grant of the Russian Fund of Humanities Research (Russian Fund of Fundamental Research) and the Krasnoyarsk Regional Science Fund under Grant number 16-11-24010.

A system for transportation of hydrocarbons at sea; System for transport av hydrokarboner til havs

Energy Technology Data Exchange (ETDEWEB)

Breivik, K.; Smedal, A.

1997-04-01

To exploit the offshore oil and gas fields economically it is important to use suitable methods and equipment for transporting the oil and gas to the landing sites. The present invention concerns a system for transportation of hydrocarbons to the landing sites. It consists of one or more loading buoys and a number of preferably conventional tankers and at least one offshore loading ship arranged to receive hydrocarbons from the loading buoy to which it is connected by means of a coupling device in the ship`s bow. The tankers have in their sterns arrangements to convey the fluid through flexible tubes from complementary arrangements in the bow of the loading ship. The loading ship and the tanker have a position reference system for mutual dynamical positioning. The entire operation of connecting the tubes and transferring the fluid flow takes place with both ships moving, at least at steerage way. The invention aims to provide efficient use of the expensive special ships that are needed to communicate with the loading buoys. Another aim is to reduce the need for expensive specialized equipment onboard both the loading ships and the tankers. 5 figs.

Darchuk, Emily M; Meunier-Goddik, Lisbeth; Waite-Cusic, Joy

2015-12-01

Hauling is a critical part of the commercial milk supply chain, yet very few studies have aimed to understand its effect on raw milk quality. This study focused on the effect of extended-duration tanker use during hauling on raw milk quality at a commercial facility. Standard tanker use [cleaned-in-place (CIP) once per 24h] served as a control and an incremental between-load water rinse with sanitizer treatment (RS) was evaluated to mitigate any effect from extended duration hauling. During this study, 1 commercial truck with 2 trailers was monitored for 10d. The truck collected milk at a large dairy farm, transported the milk to a manufacturing facility, and then returned to the same farm for a second load. Each round-trip journey took between 10 and 12h, allowing for 2 loads per 24-h use period. Following the second delivery, the truck was cleaned by CIP treatment starting a new treatment day. Producer samples were collected from the raw milk bulk tank on the farm before loading milk into the tanker. The same milk was sampled directly out of the tanker truck before unloading at the manufacturer. Effect on individual bacteria count, thermophilic spore count, and preliminary incubation count was quantified through common industry tests. Surface sponge swabs were also used to monitor tanker sanitation and the efficacy of cleaning treatments. Results did not identify a negative effect on raw milk quality due to extended duration hauling. Whereas the addition of RS did not provide any measurable quality benefits for the microbial milk quality, swab results demonstrated that the RS treatment was able to reduce surface bacteria in the tanker, although not to the same level as the full CIP treatment. Based on this study, current CIP practices for long distance milk hauling appear to be effective in mitigating any measurable effect on raw milk quality.

2000-01-01

In the Central Research Institute of Electric Power Industry, in order to confirm effects of MOX new fuel on the public are as small as possible even when its marine transport goes down, some exposed radiation dose has previously conducted on imaginary shipwreck of marine transport on used nuclear fuel, plutonium dioxide, and high level return glass solid. Under a base of such informations, some investigations on safety on marine transport of the MOX new fuel was conducted. On September, 1999, five transport vessels of the MOX new fuel was at first transported on marine. The value of five times of estimated exposed radiation dose (max. 8.1 x 10 -8 mSv/y) corresponds to an evaluation result assumed by shipwreck in marine transport this time. As a result, it was found that the exposed radiation dose estimated on this case would be sufficiently less than an effective dose equivalent limit (1 mSv/y) of public exposure according to the recommendation of ICRP in both coastal and oceanic areas.

In the fiscal 1995 study, items were searched which are keys to the design of a liquid hydrogen tanker of a capacity of 200,000m{sup 3}. Among those, the basic concepts were summarized which are necessary for the design of a liquid hydrogen tanker in terms of safety, and the extraporation of the existing low temperature technology into the large liquid hydrogen tank was studied. When adopting safety conditions of IGC Code applied to LNG to the liquid hydrogen tanker, it is necessary to limit the discharge amount of hydrogen to 3 kg/s. When considering safety at fire, for keeping safety of the same level as that of the LNG tanker, it is not appropriate to adopt the conventional vacuum insulation liquid hydrogen tank. In the fiscal 1995 study, 7 kinds of concept of the insulation structure were assumed, and it was concluded that BOR of 0.04-0.23/d was obtained. Also in fiscal 1996, the large liquid hydrogen tank was studied. For insulation of the large liquid hydrogen tank, the structure is most promising where AEROSIL bag or homogeneous AEROSIL is substituted for a forming heat insulating material of 4 design, but further study is needed for selection of the optimum heat insulating structure. 9 figs., 6 tabs.

2013-12-01

It is hard to convey the difficulties that accompany marine exploration. Veterans joke about the difficulties with mixing electricity, computers, saltwater, and boats. Often, it's declared a minor miracle when a seafloor-mapping program is successfully completed. During the summer of 2013 2 high school students and 1 undergraduate worked alongside a field scientist using geophysical techniques to try and identify a shipwreck found in shallow waters of the Chester River near Chestertown, Maryland. Over the course of 2 weeks, these 'interns' became intimately familiar with the trials and tribulations of marine fieldwork. They learned how to mobilize a small survey boat from scratch, installing and troubleshooting multiple systems from inception to operation. For example; they mobilized the Side Scan Sonar that involved shop mobilization and system checks, transfer to the boat, connecting the tow-cable, rub tests, troubleshooting the power supply, computer 'handshake' and configuring the comm ports for GPS connectivity. They designed the survey plan, directed us to the site, deployed the system, devised the file naming protocol, and collected the data. In addition to the Side Scan, they did the same for the Sub Bottom Profiler. Once the wreck was confidently located they deployed a buoy to ease the wreck location for underwater camera work. This work was compromised when the wreck was not found at the marked site and it was determined that the buoy had moved from the original deployment. When the camera was dropped, wreck identification was impossible because of the lack of visibility and the biologic growth on the boat's structure. In short, they learned that in the field 'If something could go wrong, it would'. The Interns were tasked with creating a board game that conveyed the real world activity that accompanies the good, bad, and ugly of an actual exploration including; technical, social, ethical, environmental, archaeological, historical, legal, and social

Effect of leaving milk trucks empty and idle for 6 h between raw milk loads.

Kuhn, Eva; Meunier-Goddik, Lisbeth; Waite-Cusic, Joy G

2018-02-01

The US Pasteurized Milk Ordinance (PMO) allows milk tanker trucks to be used repeatedly for 24 h before mandatory clean-in-place cleaning, but no specifications are given for the length of time a tanker can be empty between loads. We defined a worst-case hauling scenario as a hauling vessel left empty and dirty (idle) for extended periods between loads, especially in warm weather. Initial studies were conducted using 5-gallon milk cans (pilot-scale) as a proof-of-concept and to demonstrate that extended idle time intervals could contribute to compromised raw milk quality. Based on pilot-scale results, a commercial hauling study was conducted through partnership with a Pacific Northwest dairy co-op to verify that extended idle times of 6 h between loads have minimal influence on the microbiological populations and enzyme activity in subsequent loads of milk. Milk cans were used to haul raw milk (load 1), emptied, incubated at 30°C for 3, 6, 10, and 20 h, and refilled with commercially pasteurized whole milk (load 2) to measure cross-contamination. For the commercial-scale study, a single tanker was filled with milk from a farm known to have poorer quality milk (farm A, load 1), emptied, and refilled immediately (0 h) or after a delay (6 h) with milk from a farm known to have superior quality milk (farm B, load 2). In both experiments, milk samples were obtained from each farm's bulk tank and from the milk can or tanker before unloading. Each sample was microbiologically assessed for standard plate count (SPC), lactic acid bacteria (LAB), and coliform counts. Selected isolates were assessed for lipolytic and proteolytic activity using spirit blue agar and skim milk agar, respectively. The pilot-scale experiment effectively demonstrated that extended periods of idle (>3 h) of soiled hauling vessels can significantly affect the microbiological quality of raw milk in subsequent loads; however, extended idle times of 6 h or less would not measurably compromise milk

2014-07-15

The Egadi Marine Protected Area (MPA) on the western side of the Sicily Channel (Central Mediterranean) is exposed to a high risk of oil pollution from the tanker routes connecting the eastern and western basins of the Mediterranean Sea. Areas where an oil spill would do most damage, and thus where surveillance should be concentrated, are identified in this study by Lagrangian tracers tracked backwards in time from points along the MPA perimeter using data spanning six years from 2006 to 2011. Results indicate that the areas where oil surveillance would be most beneficial are segments of the tanker routes south of Sicily (highly frequented) and north of Sicily (scarcely frequented), both extending about 150 miles from November to March and 100 miles in the other months. The third route, close to the Tunisian shore, is the most frequented by oil tankers but the threat period is limited to November and December. Copyright © 2014 Elsevier Ltd. All rights reserved.

Analysis of the effects of explosion of a hydrogen cylinder on the transfer of radioactive liquid wastes at nuclear power stations

International Nuclear Information System (INIS)

Lopes, Karina B.; Melo, Paulo Fernando F.F. e

2011-01-01

This work presents a study of explosion effects of a stored hydrogen cylinder on the transfer of radioactive liquid wastes at nuclear power plants. The peak overpressure is calculated, as well as the strength of resulting fragments, thus confirming the main harmful effect of an explosion of flammable vapor cloud, based on the TNT equivalent method. The scenarios identified are calculated and compared with the overpressure ranges of 1%, 50% and 99% of structural damages, which were determined by the Eisenberg's vulnerability model. The results show that the overpressure and the resulting fragments from the explosion of a hydrogen gas cylinder are not able to cause the overturning of the tanker under study, and also show that a minimum distance of 30 meters between the hydrogen cylinder and the tanker can be considered a safe distance to the passage of this tanker during the transfer of radioactive liquid waste, in which the likelihood of occurrence of structural damages is less than 1%.

The coast of Guerrero Negro (Baja California) has been known for a long time by archaeologists for its shipwrecks. Archaeologists are recovering objects that come from sunken Spanish galleons in the colonial period, and reach the American coast in the frontier of the USA with Mexico. An enamelled metallic object was found next to the beach in Guerrero Negro. We have analysed the piece with proton induced X-ray emission (PIXE) and Rutherford backscattering (RBS) in an attempt to establish whether the object could come from one of the colonial shipwrecks and to valuate its cleaning process. Scanning electron microscopy (SEM) and energy dispersive X-ray spectrometry (EDS) have been also performed in three samples taken from the object in order to observe the heterogeneity of the material. The materials found revealed the presence of typical lead-glass enamels from with pigments such as cuprite (red), or lead-tin yellow used in colonial times. The metallic part consisted of brass. As for the cleaning process, the average efficiency considered as the weight% of chlorine removed, was of 83.4% for brass and 100% for enamels

The coast of Guerrero Negro (Baja California) has been known for a long time by archaeologists for its shipwrecks. Archaeologists are recovering objects that come from sunken Spanish galleons in the colonial period, and reach the American coast in the frontier of the USA with Mexico. An enamelled metallic object was found next to the beach in Guerrero Negro. We have analysed the piece with proton induced X-ray emission (PIXE) and Rutherford backscattering (RBS) in an attempt to establish whether the object could come from one of the colonial shipwrecks and to valuate its cleaning process. Scanning electron microscopy (SEM) and energy dispersive X-ray spectrometry (EDS) have been also performed in three samples taken from the object in order to observe the heterogeneity of the material. The materials found revealed the presence of typical lead-glass enamels from with pigments such as cuprite (red), or lead-tin yellow used in colonial times. The metallic part consisted of brass. As for the cleaning process, the average efficiency considered as the weight% of chlorine removed, was of 83.4% for brass and 100% for ename0008.

SR-71B - in Flight with F-18 Chase Aircraft - View from Air Force Tanker

Science.gov (United States)

1996-01-01

NASA 831, an SR-71B operated by the Dryden Flight Research Center, Edwards, California, cruises over the Mojave Desert with an F/A-18 Hornet flying safety chase. They were photographed on a 1996 mission from an Air Force refueling tanker The F/A-18 Hornet is used primarily as a safety chase and support aircraft at Dryden. As support aircraft, the F-18s are used for safety chase, pilot proficiency and aerial photography. Two SR-71 aircraft have been used by NASA as testbeds for high-speed and high-altitude aeronautical research. The aircraft, an SR-71A and an SR-71B pilot trainer aircraft, have been based here at NASA's Dryden Flight Research Center, Edwards, California. They were transferred to NASA after the U.S. Air Force program was cancelled. As research platforms, the aircraft can cruise at Mach 3 for more than one hour. For thermal experiments, this can produce heat soak temperatures of over 600 degrees Fahrenheit (F). This operating environment makes these aircraft excellent platforms to carry out research and experiments in a variety of areas -- aerodynamics, propulsion, structures, thermal protection materials, high-speed and high-temperature instrumentation, atmospheric studies, and sonic boom characterization. The SR-71 was used in a program to study ways of reducing sonic booms or over pressures that are heard on the ground, much like sharp thunderclaps, when an aircraft exceeds the speed of sound. Data from this Sonic Boom Mitigation Study could eventually lead to aircraft designs that would reduce the 'peak' overpressures of sonic booms and minimize the startling affect they produce on the ground. One of the first major experiments to be flown in the NASA SR-71 program was a laser air data collection system. It used laser light instead of air pressure to produce airspeed and attitude reference data, such as angle of attack and sideslip, which are normally obtained with small tubes and vanes extending into the airstream. One of Dryden's SR-71s was used

In this paper we present a photogrammetry-based approach for deep-sea underwater surveys conducted from a submarine and guided by knowledge-representation combined with a logical approach (ontology). Two major issues are discussed in this paper. The first concerns deep-sea surveys using photogrammetry from a submarine. Here the goal was to obtain a set of images that completely covered the selected site. Subsequently and based on these images, a low-resolution 3D model is obtained in real-time, followed by a very high-resolution model produced back in the laboratory. The second issue involves the extraction of known artefacts present on the site. This aspect of the research is based on an a priori representation of the knowledge involved using systematic reasoning. Two parallel processes were developed to represent the photogrammetric process used for surveying as well as for identifying archaeological artefacts visible on the sea floor. Mapping involved the use of the CIDOC-CRM system (International Committee for Documentation (CIDOC)—Conceptual Reference Model)—This is a system that has been previously utilised to in the heritage sector and is largely available to the established scientific community. The proposed theoretical representation is based on procedural attachment; moreover, a strong link is maintained between the ontological description of the modelled concepts and the Java programming language which permitted 3D structure estimation and modelling based on a set of oriented images. A very recently discovered shipwreck acted as a testing ground for this project; the Xelendi Phoenician shipwreck, found off the Maltese coast, is probably the oldest known shipwreck in the western Mediterranean.

Full Text Available The release of hydrocarbons and chemical dispersant in marine environments may disrupt benthic ecosystems, including artificial reefs, formed by historic steel shipwrecks, and their associated organisms. Experiments were performed to determine the impacts of crude oil, dispersed crude oil, and dispersant on the community structure and function of microorganisms in seawater (SW and biofilms formed on carbon steel, a common ship hull construction material. Steel corrosion was also monitored to illustrate how oil spills may impact preservation of steel shipwrecks. Microcosms were filled with seawater (SW and incubated at 4°C. Carbon steel disks (CSDs were placed in each tank, and tanks were amended with crude oil and/or dispersant or no treatment. SW and CSD biofilms were sampled biweekly for genetic analysis using Illumina sequencing of 16S ribosomal RNA gene amplicons. Predicted and sequenced bacterial metagenomes were analyzed to examine impacts of oil and dispersant on metabolic function. Gammaproteobacteria, Alphaproteobacteria, and Flavobacteriia dominated SW and biofilms. Bacterial community structure differed significantly between treatments for SW and biofilms. OTUs affiliated with known (Pseudomonas and potential (Marinomonas hydrocarbon-degraders were roughly twice as abundant in biofilms treated with oil and dispersed oil, and steel corrosion of CSDs in these treatments was higher compared to control and dispersant treatments. OTUs affiliated with the Rhodobacteraceae family (biofilm formers and potential oil degraders were less abundant in the dispersant treatment compared to other treatments in biofilm and SW samples, but OTUs affiliated with the Pseudoalteromonas genus (biofilm formers and proposed hydrocarbon degraders were more abundant in dispersant-treated biofilms. Overall, functional gene analyses revealed a decrease in genes (predicted using PICRUSt and observed in sequenced metagenomes associated with hydrocarbon degradation

TOVALOP and CRISTAL. 2. ed.

International Nuclear Information System (INIS)

1990-01-01

The Torrey Canyon incident in 1967 provided a major stimulus to the development of four international regimes (two voluntary agreements and two international conventions) through which compensation for pollution damage and clean-up costs is available following the escape or discharge of persistent oil from tankers. The two voluntary agreements were set up as a result of the determination of the tanker and oil industries to take constructive action, both to encourage prompt and effective clean-up and to assure adequate and timely compensation, prior to the widespread ratification and acceptance of the two international conventions. The voluntary agreements are the Tanker Owners Voluntary Agreement concerning Liability for Oil Pollution (TOVALOP) and the Contract Regarding a Supplement to Tanker Liability for Oil Pollution (CRISTAL). It should be emphasised from the outset that whilst both TOVALOP and CRISTAL are described as voluntary agreements, it is only the decision on whether or not to participate that is voluntary, since having become a party there is a contractual obligation to meet all the terms and conditions of the applicable agreement. This booklet provides a brief summary of TOVALOP and CRISTAL and their relation to the corresponding international conventions developed under the auspices of the International Maritime Organization (IMO), viz the International Convention on Civil Liability for Oil Pollution Damage, 1969 (CLC) and the International Convention on the Establishment of an International Fund for Compensation for Oil Pollution Damage, 1971 (Fund Convention).

Atlantic Canada, on watch : Canadian Coast Guard sails to rescue of oiled wildlife

Energy Technology Data Exchange (ETDEWEB)

Reid, W.

1999-08-02

The impact that tanker ships have left on the marine ecosystem on Newfoundland`s south coast was discussed. Tankers and container ships have sometimes discharged leftover bunker-C fuel before entering the St. Lawrence Seaway to save on cleaning services. It is estimated that 60,000 to 100,000 of the 30 million seabirds which reside or migrate through the ecological reserve around St. Mary`s Bay, die each year from the effects of oil. Victims are mostly puffins, seagulls and murres. This paper discussed the involvement of the Canadian Coast Guard in the Prevention of Oiled Wildlife (POW) project. POW has compared British Columbia`s shipping practices with those of Newfoundland. Although crude oil shipments along the B.C. coast exceed 250 million barrels annually, seabirds are not being oiled by passing tankers. It was suggested that in order to change attitudes in Atlantic waters, the maximum fine of $1 million against offenders should be imposed. So far, the highest penalty levied by Transport Canada has been $30,000. It was argued that this is not a significant deterrent for most polluters.

A guidance law for UAV autonomous aerial refueling based on the iterative computation method

Directory of Open Access Journals (Sweden)

Luo Delin

2014-08-01

Full Text Available The rendezvous and formation problem is a significant part for the unmanned aerial vehicle (UAV autonomous aerial refueling (AAR technique. It can be divided into two major phases: the long-range guidance phase and the formation phase. In this paper, an iterative computation guidance law (ICGL is proposed to compute a series of state variables to get the solution of a control variable for a UAV conducting rendezvous with a tanker in AAR. The proposed method can make the control variable converge to zero when the tanker and the UAV receiver come to a formation flight eventually. For the long-range guidance phase, the ICGL divides it into two sub-phases: the correction sub-phase and the guidance sub-phase. The two sub-phases share the same iterative process. As for the formation phase, a velocity coordinate system is created by which control accelerations are designed to make the speed of the UAV consistent with that of the tanker. The simulation results demonstrate that the proposed ICGL is effective and robust against wind disturbance.

The LNG Industry - 2010

2011-04-01

In 2010, global energy demand has recovered. Estimates for World Natural Gas consumption show a 7.3% increase compared with 2009 thanks to the economic rally and the cold winter conditions in Western countries. Due to the decline of indigenous productions in mature markets and to the development of new gas markets, international gas flows continued to expand, and total international gas trade increased by 10.9% compared with 2009. In this context, LNG flows recorded the largest growth with a 21% increase in 2010, the operational start-up of new liquefaction capacity in Qatar being the primary reason. By comparison, pipeline trade increased by 7%.

Hannah Arendt og pædagogikken

DEFF Research Database (Denmark)

Korsgaard, Morten Timmermann

Hannah Arendt er en af det 20. århundredes store politiske tænkere. Hovedværkerne Det totalitære samfundssystems oprindelse, Menneskets vilkår og Eichmann i Jerusalem er centrale skrifter i den politiske filosofi og behandler vigtige emner som totalitarisme, menneskelig handling og ondskab. Derfor...... er Arendts ganske vist få og sporadiske ─ men ikke mindre vigtige ─ tanker om pædagogikken også en smule oversete. Og ikke nok med det: De fleste pædagogiske fortolkere af Arendt læser med Arendt mod Arendt i stedet for at følge Arendts tænkning om skole og opdragelse til ende. Det forsøger dette...... lille skrift at råde bod på. Arendts tanker om pædagogikken udgør nemlig et væsentligt alternativ til de tanker om pædagogik, der er fremherskende i dag, og giver et nyt perspektiv på pædagogikken. Bogen argumenterer bl.a. for, at man med ideerne om læringssamfundet og konkurrencestaten helt glemmer...

The frequency of chromosome aberrations (CA) and micronuclei (MN) was investigated in the peripheral lymphocytes of workers occupationally exposed to low or very low concentrations of benzene. The study included 43 exposed workers (all males), namely 19 fuel-tanker drivers and 24 filling-station attendants, and 31 male subjects with no occupational exposure to the toxicant (controls). Benzene exposure was verified by means of environmental monitoring with passive personal samplers (Radiello(®)), and through biological monitoring, i.e. by measurement of urinary trans,trans-muconic acid, S-phenylmercapturic acid and benzene. The frequency of CA and MN in peripheral lymphocytes was determined according to standard procedures. Exposure to benzene was found to be significantly higher for fuel-tanker drivers (median 246.6 μg/m(3)) than for filling-station attendants (median 19.9 μg/m(3)). Both groups had significantly higher exposure than controls (median 4.3 μg/m(3)). No increased frequency of CA and MN was observed in either fuel-tanker drivers or filling-station attendants compared with controls. In all subjects examined as a single group, the frequency of MN was significantly dependent on age. Only in the fuel-tanker drivers was the frequency of MN found to depend not only on age, but also on exposure to benzene. In conclusion, the frequency of MN, but not of CA, could be influenced by exposure to benzene concentrations of up to one order of magnitude lower than the threshold limit value (time-weighted average).

Hatch, Leila; Clark, Christopher; Merrick, Richard; Van Parijs, Sofie; Ponirakis, Dimitri; Schwehr, Kurt; Thompson, Michael; Wiley, David

2008-11-01

In 2006, we used the U.S. Coast Guard's Automatic Identification System (AIS) to describe patterns of large commercial ship traffic within a U.S. National Marine Sanctuary located off the coast of Massachusetts. We found that 541 large commercial vessels transited the greater sanctuary 3413 times during the year. Cargo ships, tankers, and tug/tows constituted 78% of the vessels and 82% of the total transits. Cargo ships, tankers, and cruise ships predominantly used the designated Boston Traffic Separation Scheme, while tug/tow traffic was concentrated in the western and northern portions of the sanctuary. We combined AIS data with low-frequency acoustic data from an array of nine autonomous recording units analyzed for 2 months in 2006. Analysis of received sound levels (10-1000 Hz, root-mean-square pressure re 1 microPa +/- SE) averaged 119.5 +/- 0.3 dB at high-traffic locations. High-traffic locations experienced double the acoustic power of less trafficked locations for the majority of the time period analyzed. Average source level estimates (71-141 Hz, root-mean-square pressure re 1 microPa +/- SE) for individual vessels ranged from 158 +/- 2 dB (research vessel) to 186 +/- 2 dB (oil tanker). Tankers were estimated to contribute 2 times more acoustic power to the region than cargo ships, and more than 100 times more than research vessels. Our results indicate that noise produced by large commercial vessels was at levels and within frequencies that warrant concern among managers regarding the ability of endangered whales to maintain acoustic contact within greater sanctuary waters.

EIA cites importance of key world shipping routes

International Nuclear Information System (INIS)

Anon.

1994-01-01

A disruption of crude oil or products shipments through any of six world chokepoints would cause a spike in oil prices, the US Energy Information Administration (EIA) warns. The strategic importance of each major shipping lane varies because of differing oil volumes and access to other transportation routes. But nearly half of the 66 million b/d of oil consumed worldwide flows through one or more of these key tanker routes, involving: 14 million b/d through the Strait of Hormuz from the Persian Gulf to the Gulf of Oman and Arabian Sea; 7 million b/d through the Strait of Malacca from the northern Indian Ocean into the South China Sea and Pacific Ocean; 1.6 million b/d through the Bosporus from the Black Sea to the Mediterranean Sea; 900,000 b/d through the Suez Canal from the Red Sea to the Mediterranean Sea; 600,000 b/d through Rotterdam Harbor from the North Sea to Dutch and German refineries on or near the Rhine River; and 500,000 b/d through the Panama Canal from the Pacific Ocean to the Caribbean Sea. In today's highly interdependent oil markets, the mere perception of less secure oil supplies is enough to boost oil prices, EIA said. Growing oil and product tanker traffic is increasing the likelihood of supply disruptions through oil arteries because of bad weather, tanker collisions, or acts of piracy, terrorism, or war. What's more, the increasing age of the world tanker fleet and dependability of navigational equipment could increase chances of accidents and, therefore, oil supply disruptions

In aquatic environments, polycyclic aromatic hydrocarbons (PAHs) mostly occur as complex mixtures, for which risk assessment remains problematic. To better understand the effects of PAH mixture toxicity on fish early life stages, this study compared the developmental toxicity of three PAH complex mixtures. These mixtures were extracted from a PAH-contaminated sediment (Seine estuary, France) and two oils (Arabian Light and Erika). For each fraction, artificial sediment was spiked at three different environmental concentrations roughly equivalent to 0.5, 4, and 10 μg total PAH g(-1) dw. Japanese medaka embryos were incubated on these PAH-spiked sediments throughout their development, right up until hatching. Several endpoints were recorded at different developmental stages, including acute endpoints, morphological abnormalities, larvae locomotion, and genotoxicity (comet and micronucleus assays). The three PAH fractions delayed hatching, induced developmental abnormalities, disrupted larvae swimming activity, and damaged DNA at environmental concentrations. Differences in toxicity levels, likely related to differences in PAH proportions, were highlighted between fractions. The Arabian Light and Erika petrogenic fractions, containing a high proportion of alkylated PAHs and low molecular weight PAHs, were more toxic to Japanese medaka early life stages than the pyrolytic fraction. This was not supported by the toxic equivalency approach, which appeared unsuitable for assessing the toxicity of the three PAH fractions to fish early life stages. This study highlights the potential risks posed by environmental mixtures of alkylated and low molecular weight PAHs to early stages of fish development.

1990-07-01

Time-weighted average (TWA) intensity of exposure of workers to benzene vapor during a shift was monitored by diffusive sampling technique in a Japanese petroleum refinery. The subjects monitored (83 in total) included refinery operators, laboratory personnel and tanker-loading workers. The results showed that the time-weighted average exposures are well below 1 ppm in most cases. The highest exposure was recorded in 1 case involved in bulk loading of tanker ships, in which exposure of over 1 ppm might take place depending on operational conditions. The observation was generally in agreement with levels previously reported.

Atlantic Canada, on watch : Canadian Coast Guard sails to rescue of oiled wildlife

Energy Technology Data Exchange (ETDEWEB)

Reid, W

1999-08-02

The impact that tanker ships have left on the marine ecosystem on Newfoundland's south coast was discussed. Tankers and container ships have sometimes discharged leftover bunker-C fuel before entering the St. Lawrence Seaway to save on cleaning services. It is estimated that 60,000 to 100,000 of the 30 million seabirds which reside or migrate through the ecological reserve around St. Mary's Bay, die each year from the effects of oil. Victims are mostly puffins, seagulls and murres. This paper discussed the involvement of the Canadian Coast Guard in the Prevention of Oiled Wildlife (POW) project. POW has compared British Columbia's shipping practices with those of Newfoundland. Although crude oil shipments along the B.C. coast exceed 250 million barrels annually, seabirds are not being oiled by passing tankers. It was suggested that in order to change attitudes in Atlantic waters, the maximum fine of $1 million against offenders should be imposed. So far, the highest penalty levied by Transport Canada has been $30,000. It was argued that this is not a significant deterrent for most polluter00.

Vibration Considerations for Cryogenic Tanks Using Glass Bubbles Insulation

Science.gov (United States)

Werlink, Rudolph J.; Fesmire, James E.; Sass, Jared P.

2011-01-01

The use of glass bubbles as an efficient and practical thermal insulation system has been previously demonstrated in cryogenic storage tanks. One such example is a spherical, vacuum-jacketed liquid hydrogen vessel of 218,000 liter capacity where the boiloff rate has been reduced by approximately 50 percent. Further applications may include non-stationary tanks such as mobile tankers and tanks with extreme duty cycles or exposed to significant vibration environments. Space rocket launch events and mobile tanker life cycles represent two harsh cases of mechanical vibration exposure. A number of bulk fill insulation materials including glass bubbles, perlite powders, and aerogel granules were tested for vibration effects and mechanical behavior using a custom design holding fixture subjected to random vibration on an Electrodynamic Shaker. The settling effects for mixtures of insulation materials were also investigated. The vibration test results and granular particle analysis are presented with considerations and implications for future cryogenic tank applications. A thermal performance update on field demonstration testing of a 218,000 L liquid hydrogen storage tank, retrofitted with glass bubbles, is presented. KEYWORDS: Glass bubble, perlite, aerogel, insulation, liquid hydrogen, storage tank, mobile tanker, vibration.

First Stabilization and Disposal of Radioactive Zinc Bromide at the SRS

International Nuclear Information System (INIS)

Denny, J.K.

2003-01-01

Facilities Disposition Projects (FDP) personnel at Savannah River Site (SRS) implement the Inactive Facility Risk Management Program to drive down risk and costs in SRS inactive facilities. The program includes cost-effective techniques to identify and dispose of hazardous chemicals and radioactive waste from inactive facilities, thereby ensuring adequate protection of the public, workers and the environment. In June 1998, FDP conducted an assessment of the inactive C-Reactor Facility to assure that chemical and radiological hazards had been identified and were being safely managed. The walkdown identified the need to mitigate a significant hazard associated with storing approximately 13,400 gallons of liquid radioactive Zinc Bromide in three aging railcar tankers outside of the facility. No preventive maintenance was being performed on the rusting tankers and a leak could send radioactive Zinc Bromide into an outfall and offsite to the Savannah River. In 2001, DOE-Savannah River (DOE- SR) funded the FDP to eliminate the identified hazard by disposing of the radioactive Zinc Bromide solution and the three contaminated railcar tankers. This paper describes the innovative, cost-effective approaches and technology used to perform the first stabilization and disposal of radioactive Zinc Bromide at SRS

Arctic Islands LNG

Energy Technology Data Exchange (ETDEWEB)

Hindle, W.

1977-01-01

Trans-Canada Pipe Lines Ltd. made a feasibility study of transporting LNG from the High Arctic Islands to a St. Lawrence River Terminal by means of a specially designed and built 125,000 cu m or 165,000 cu m icebreaking LNG tanker. Studies were made of the climatology and of ice conditions, using available statistical data as well as direct surveys in 1974, 1975, and 1976. For on-schedule and unimpeded (unescorted) passage of the LNG carriers at all times of the year, special navigation and communications systems can be made available. Available icebreaking experience, charting for the proposed tanker routes, and tide tables for the Canadian Arctic were surveyed. Preliminary design of a proposed Arctic LNG icebreaker tanker, including containment system, reliquefaction of boiloff, speed, power, number of trips for 345 day/yr operation, and liquefaction and regasification facilities are discussed. The use of a minimum of three Arctic Class 10 ships would enable delivery of volumes of natural gas averaging 11.3 million cu m/day over a period of a year to Canadian markets. The concept appears to be technically feasible with existing basic technology.

Compensation for oil pollution damage caused by oil spills from ships and the International Oil Pollution Compensation Fund

International Nuclear Information System (INIS)

Jacobsson, M.

1994-01-01

Liability and compensation for pollution damage caused by oil spills from laden tankers is governed by two international conventions: the 1969 Civil Liability Convention and the 1971 Fund Convention. The Civil Liability Convention established a system of strict liability for tanker owners and introduced compulsory liability insurance. The Fund Convention created a system of supplementary compensation administered by an intergovernmental organization, the International Oil Pollution Compensation Fund (IOPC Fund), which at present has 56 member states (August 1993). The IOPC Fund pays compensation to victims of oil pollution in member states when the compensation from the ship owner and his insurer is insufficient. (author)

[Correction Notice: An Erratum for this article was reported in Vol 63(5) of Journal of Counseling Psychology (see record 2016-33161-001). The name of author Erika Feinauer was misspelled as Erika Feinhauer. All versions of this article have been corrected.] Individuals' strength of ethnic identity has been linked with multiple positive indicators, including academic achievement and overall psychological well-being. The measure researchers use most often to assess ethnic identity, the Multigroup Ethnic Identity Measure (MEIM), underwent substantial revision in 2007. To inform scholars investigating ethnic identity, we performed a reliability generalization analysis on data from the revised version (MEIM-R) and compared it with data from the original MEIM. Random-effects weighted models evaluated internal consistency coefficients (Cronbach's alpha). Reliability coefficients for the MEIM-R averaged α = .88 across 37 samples, a statistically significant increase over the average of α = .84 for the MEIM across 75 studies. Reliability coefficients for the MEIM-R did not differ across study and participant characteristics such as sample gender and ethnic composition. However, consistently lower reliability coefficients averaging α = .81 were found among participants with low levels of education, suggesting that greater attention to data reliability is warranted when evaluating the ethnic identity of individuals such as middle-school students. Future research will be needed to ascertain whether data with other measures of aspects of personal identity (e.g., racial identity, gender identity) also differ as a function of participant level of education and associated cognitive or maturation processes.

Malaysian coasts are subjected to various threats of petroleum pollution including routine and accidental oil spill from tankers, spillage of crude oils from inland and offshore oil fields, and run-off from land-based human activities. Due to its strategic location, the Straits of Malacca serves as a major shipping lane. This paper expands the utility of biomarker compounds, hopanes, in identifying the source of tar-balls stranded on Malaysian coasts. 20 tar-ball samples collected from the east and west coast were analysed for hopanes and polycylic aromatic hydrocarbons (PAHs). Four of the 13 tar-ball samples collected from the west coast of Peninsular Malaysia were identified as the Middle East crude oil (MECO) based on their biomarker signatures, suggesting tanker-derived sources significantly contributing the petroleum pollution in the Straits of Malacca. The tar-balls found on the east cost seem to originate from the offshore oil platforms in the South China Sea. The presence of South East Asian crude oil (SEACO) tar-balls on the west coast carry several plausible explanations. Some of the tar-balls could have been transported via sea currents from the east coast. The tankers carrying SEACO to other countries could have accidentally spilt the oil as well. Furthermore, discharge of tank washings and ballast water from the tankers were suggested based on the abundance in higher molecular weight n-alkanes and the absence of unresolved complex mixture (UCM) in the tar-ball samples. The other possibilities are that the tar-balls may have originated from the Sumatran oil fields and spillage of domestic oil from oil refineries in Port Dickson and Malacca. The results of PAHs analysis suggest that all the tar-ball samples have undergone various extent of weathering through evaporation, dissolution and photo-oxidation. (Author)

Contrary to previous linear projections of steel corrosion in seawater, analysis of an inert marker embedded in USS Arizona concretion since the 7 December 1941 attack on Pearl Harbor reveals evidence that the effective corrosion rate decreases with time. The secant rate of corrosion, or SRC correlation, derived from this discovery could have a significant impact on failure analysis investigations for concreted shipwrecks or underwater structures. The correlation yields a lower rate of metal thinning than predicted. Development of the correlation is described.

The invention relates to a vessel for offshore loading. The vessel comprises a number of centre tanks arranged in the longitudinal direction of the vessel, and a number of wing tanks located in pairs on either side of respective centre tanks. A loading line is connected to the centre tanks via respective valves, and adjacent centre tanks are connected to each other via bulkhead valves. The method comprises the steps firstly effecting filling of a desired number of the centre tanks. These are substantially narrower and having a correspondingly smaller volume than the wing tanks. Thereafter opening bulkhead valves between a centre tank and an appurtenant wing tank pair and sluicing out oil from centre tanks into the two wing tanks by means of the static pressure from the centre tank. The bulkhead valves between the centre tanks being open, so that the wing tank pair is filled as quickly as possible by suitable operation of the bulkhead valves between the centre tanks and of the valves of the loading line to the centre tanks. Closing the bulkhead valves to the two wing tanks when these and the appurtenant centre tank are filled to a desired level, and repeating the filling process to the steps and successively for additional wing tank pairs after that all centre tanks have been filled again. 10 figs.

Transport woes threaten California production

International Nuclear Information System (INIS)

Anon.

1994-01-01

California oil producers face a loss of production this year because of constraints on pipeline and tanker transportation to Los Angeles area refineries. The potential bottleneck is occurring at a time when Outer Continental Shelf production is near capacity from Chevron Corp.'s Point Arguello project at the same time production is increasing from Exxon Corp.'s nearby Santa Ynex Unit (SYU) expansion. Both megaprojects must compete for pipeline space with onshore crude producers, notably in California's San Joaquin Valley (SJV). Recent development limiting transportation options include: An indefinite shutdown of Four Corners Pipe Line Co.'s 50,000 b/d Line No. 1, damaged by the Jan. 17 earthquake; Loss of a tanker permit by Chevron and partners for offshore Point Arguello production; Permanent shutdown of Exxon's offshore storage and treatment (OST) facility, which since 1981 has used tankers to transport about 20,000 b/d of SYU production from the Santa Barbara Channel to Los Angeles. The OST, the first commercial floating production system in the US -- placed in the Santa Barbara Channel in 1981 after a decade of precedent setting legal and political battles -- was shut down Apr. 4. The paper discusses these production concerns, available options, the OST shutdown, and the troubled history of the OST

Trends in CO2 Emissions from China-Oriented International Marine Transportation Activities and Policy Implications

Directory of Open Access Journals (Sweden)

Hualong Yang

2017-07-01

Full Text Available The demand for marine transportation and its associated CO2 emissions are growing rapidly as a result of increasing international trade and economic growth. An activity-based approach is developed for forecasting CO2 emissions from the China-oriented international seaborne trade sector. To accurately estimate the aggregated emissions, CO2 emissions are calculated individually for five categories of vessels: crude oil tanker, product tanker, chemical tanker, bulk carrier, and container. A business-as-usual (BAU scenario was developed to describe the current situation without additional mitigation policies, whilst three alternative scenarios were developed to describe scenarios with various accelerated improvements of the key factors. The aggregated CO2 emissions are predicted to reach 419.97 Mt under the BAU scenario, and 258.47 Mt under the optimal case, AD3. These predictions are 4.5 times and 2.8 times that of the aggregated emissions in 2007. Our analysis suggests that regulations for monitoring, reporting, and verifying the activities of vessels should be proposed, in order to quantify the CO2 emissions of marine transportation activities in Chinese territorial waters. In the long-term future, mitigation policies should be employed to reduce CO2 emissions from the marine trade sector and to address the climatic impact of shipping.

Improving sustainability of maritime transport through utilization of Liquefied Natural Gas (LNG) for propulsion

International Nuclear Information System (INIS)

Burel, Fabio; Taccani, Rodolfo; Zuliani, Nicola

2013-01-01

Today, most merchant vessels use Heavy Fuel Oils (HFOs) for ship propulsion. These fuels are cost effective but they produce significant amounts of noxious emissions. In order to comply with International Maritime Organization (IMO) rules, Liquefied Natural Gas (LNG) is becoming an interesting option for merchant ships. The aim of the research presented in this paper is to analyse the economic upturn that can result from the use of LNG as fuel for merchant ships and to assess the effects of its utilization in terms of environmental impact. In the first part of the study, a statistical analysis of maritime traffic is carried out in order to identify which merchant ship types could most benefit from using LNG as fuel for ship propulsion. Traffic data of world ships related to the months of May 2008, 2009 and 2010 are analysed. Roll-on/Roll-off vessels (RoRo) and tanker ships spend most of their sailing time in Emission Control Areas (ECA) consequently appear to be the best candidates for LNG use. In particular, the use of LNG is most profitable for tanker ships in the range of 10,000–60,000 DWT (deadweight). In the second part of the study, operational costs and pollutant emission reduction, following LNG implementation, are calculated for a 33,000 DWT tanker ship. Results show that LNG leads to a reduction of 35% of operational costs and 25% of CO 2 emissions. The possibility of improving energy efficiency on board is analysed considering that combustion gases, produced by LNG, are cleaner, thus simplifying the introduction of exhaust gas heat recovery. Two options are considered: simple heat recovery and heat recovery to drive a turbine (ORC). The results show that it is possible to achieve a reduction in fuel consumption of up to 15%. - Highlights: • Ship propulsion accounts for a large amount of noxious emissions in costal/harbour areas. • Today price differential between fuel oil and natural gas is increasing. • The use of Liquefied Natural Gas as fuel

Shuttles set for US Gulf lift off

Energy Technology Data Exchange (ETDEWEB)

DeLuca, Marshall

2002-09-01

The author reports on discussions with two US companies about plans for using shuttle tankers to transport oil from platforms in the Gulf of Mexico to US ports as an alternative to pipeline networks. This follows approval by the US Minerals Management Service for FPSOs in the Gulf. The companies are American Shuttle Tankers and Conoco-owned Seahorse Shuttling and Technology. Because the vessels will enter US ports and operate in US waters, they must conform with the US Jones Act: they must be US-built, US-flagged and manned by US crews. They must also be double-hulled. This increases cost and reduces market opportunities for the vessels outside the US. The article also considers the use of articulated tug barges as another option. (UK)

'Jail break' made by Iraqi oil tankers

Lorenz, A.

2000-01-01

The implications of Iran's policy turn-about of allowing ships smuggling Iraqi crude oil to sail through its coastal waters, out of reach of UN and US ships patrolling the Persian Gulf, are discussed. It is suspected that the change in Iranian policy may be due to the fact that an infusion of Iraqi oil on the international markets would suit Iran's purposes by reducing the need for OPEC to raise production quotas. Iran is known to be opposed to an increase of production by OPEC members. At the same time, developments in US-Iranian relations and in the international oil market also have to be considered as factors influencing the Iranian position on this issue

ASSESSMENT OF THE DEEP SEA WRECK USS INDEPENDENCE

Directory of Open Access Journals (Sweden)

Lisa C. Symons

2016-07-01

Full Text Available As part of ongoing efforts to better understand the nature of shipwrecks in National Marine Sanctuaries which may pose some level of pollution risk, and in this case, to definitively locate what is likely the only shipwreck in a sanctuary involved in both nuclear testing and nuclear waste disposal, NOAA’s Office of National Marine Sanctuaries collaborated with NOAA’s Office of Ocean Exploration and The Boeing Company, which provided their autonomous underwater vehicle, Echo Ranger, to conduct the first deep-water archaeological survey of the scuttled aircraft carrier USS Independence in the waters of Monterey Bay National Marine Sanctuary (MBNMS in March 2015. The presence of the deep-sea scuttled radioactive aircraft carrier USS Independence off the California coast has been the source of consistent media speculation and public concern for decades. The survey confirmed that a sonar target charted at the location was Independence, and provided details on the condition of the wreck, and revealed no detectable levels of radioactivity. At the same time, new information from declassified government reports provided more detail on Independence’s use as a naval test craft for radiological decontamination as well as its use as a repository for radioactive materials at the time of its scuttling in 1951. While further surveys may reveal more, physical assessment and focused archival work has demonstrated that the level of concern and speculation of danger from either a radioactive or oil pollution threat posed may be exaggerated.

Approach to downstream planning for nearshore response and sensitive areas protection outside Prince William Sound, Alaska

International Nuclear Information System (INIS)

DeCola, E.G.; Robertson, T.L.; Robertson, R.; Banta, J.

2004-01-01

This study assessed the need for an oil spill response plan for downstream coastal communities that could be affected by oil spilled from tankers travelling in Prince William Sound, Alaska. For the purpose of oil spill contingency planning, the State of Alaska has been divided into the Kodiak and Cook Inlet sub-areas that are at risk for downstream impacts from a Prince William Sound oil spill. The 1989 Exxon Valdez oil spill provided an example of a worst-case scenario oil spill from a tanker in Prince William Sound, but the oil spill planning system that has evolved in Alaska does not adequately plan for on oil spill that originates in one sub-area of the state, but impacts other sub-areas in the downstream spill path. This study analyzed the gaps that exist in the current response planning system in the Prince William Sound, Cook Inlet and Kodiak sub-areas. A method was proposed to improve the existing response plans so that emergency response teams are better prepared to manage cross-boundary oil spills originating in Prince William Sound. The proposed method focuses on nearshore response and sensitive areas protection for coastlines and communities that are at risk for oil spills from a tanker travelling the Trans-Alaska Pipeline System (TAPS). 11 refs., 3 figs

Traffic at risk in Mediterranean

International Nuclear Information System (INIS)

Bilardo, U.; Mureddu, G.

1993-01-01

The Mediterranean Sea represents only about 0.7% of the planet's total water surface area, yet it is host to as much as one-quarter of the world's total maritime oil traffic. Statistics indicate that from 47 to 77,000 tonnes of crude oil are now being released annually into the Sea through accidental spills; and over the last decade, its tourism dependent coastlines have been fouled by the highest levels of tar contamination in the world. Oil carrier traffic, routed within the Sea's already overcrowded shipping lanes, is intense and this traffic is expected to increase, as a result of rises in world energy demand, to levels of from 7 to 8 million barrels a day. It has been estimated that, at the end of 1992, 90% of all large tankers operating in this area, will have reached a service life of 15-16 years which is very close to the average recommended life cycle limit of 15-20 years. Only 20% of the world's 3,000 tankers are currently equipped with double bottomed hulls. This paper uses these and other facts and figures to argue that the risks of future severe oil tanker accidents in the Mediterranean Sea are high, and that these must be countered with the development of a new set of stricter marine traffic safety regulations at the Italian, national, as well as, European level

This paper presents a new dynamic environmental risk model, with intended use within a new, dynamical approach for risk based ship traffic prioritisation. The philosophy behind this newly developed approach is that shipping risk can be reduced by directing efforts towards ships and areas that have been identified as high priority (high risk), prior to a potential accident. The risk model proposed in this paper separates itself from previous models by drawing on available information on dynamic factors and by focusing on the ship's surroundings. The model estimates the environmental risk of drift grounding accidents for oil tankers in real time and in forecast mode, combining the probability of grounding with oil spill impact on the coastline. Results show that the inherent dynamic risk introduced by an oil tanker sailing along the North Norwegian coast depends, not surprisingly, significantly upon wind and ocean currents, as well as tug position and cargo oil type. Results of this study indicate that the risk model is well suited for real time risk assessment, and effectively separates low risk and high risk situations. The model is well suited as a tool to prioritise oil tankers and coastal segments. This enables dynamic risk based positioning of tugs, using both real-time and projected risk, for effective support in case of a drifting ship situation.

Deposition of oil residues, also known as tar balls, is a seasonal phenomenon, and it occurs only in the southwest monsoon season along the west coast of India. This has become a serious environmental issue, as Goa is a global tourist destination. The present work aims at identifying the source oil of the tar balls that consistently depositing along the Goa coast using multi-marker fingerprint technique. In this context, the tar ball samples collected in May 2013 from 9 beaches of Goa coast and crude oils from different oil fields and grounded ship were subject to multi-marker analyses such as n-alkanes, pentacyclic terpanes, regular steranes, compound specific isotope analysis (CSIA) and principle component analysis (PCA). The n-alkane weathering index shows that samples have been weathered to various degrees, and the status of weathering is moderate. Since the international tanker route passes closer to the west coast of India (WCI), it is generally presumed that tanker wash is the source of the tar balls. We found that 2010/2011 tar balls are as tanker wash, but the present study demonstrates that the Bombay High (BH) oil fields can also contribute to oil contamination (tar balls) along ≈ 650 km stretch of the WCI, running from Gujarat in the north to Goa in the south. The simulated trajectories show that all the particles released in April traveled in the southeast direction, and by May, they reached the Goa coast with the influence of circulation of Indian monsoon system. - Highlights: • Multi-marker approach was effective in identifying the source of tar balls. • n-Alkane DRs show weathering effects even within the core of the tar ball. • Tar balls of the west coast of India since 2012 were derived from Bombay High crude. • Tanker-wash is not the only source of tar balls deposited on the beaches of Goa.

2008-01-01

In this paper, we present a detailed and comprehensive complementarity model for computing market equilibrium values in the European natural gas system. Market players include producers and their marketing arms which we call 'traders', pipeline and storage operators, marketers, LNG liquefiers, regasifiers, tankers, and three end-use consumption sectors. The economic behavior of producers, traders, pipeline and storage operators, liquefiers and regasifiers is modeled via optimization problems whose Karush-Kuhn-Tucker (KKT) optimality conditions in combination with market-clearing conditions form the complementarity system. The LNG tankers, marketers and consumption sectors are modeled implicitly via appropriate cost functions, aggregate demand curves, and ex post calculations, respectively. The model is run on several case studies that highlight its capabilities, including a simulation of a disruption of Russian supplies via Ukraine

Cost-effectiveness criteria for marine oil spill preventive measures

International Nuclear Information System (INIS)

Vanem, Erik; Endresen, Oyvind; Skjong, Rolf

2008-01-01

Oil tanker accidents resulting in large quantities of oil spills and severe pollution have occurred in the past, leading to major public attention and an international focus on finding solutions for minimising the risks related to such events. This paper proposes a novel approach for evaluating measures for prevention and control of marine oil spills, based on considerations of oil spill risk and cost effectiveness. A cost model that incorporates all costs of a shipping accident has been established and oil tanker spill accidents have been further elaborated as a special case of such accidents. Utilising this model, novel implementation criteria, in terms of the Cost of Averting a Tonne of oil Spilt (CATS), for risk control options aiming at mitigating the environmental risk of accidental oil spills, are proposed. The paper presents a review of previous studies on the costs associated with oil spills from shipping, which is a function of many factors such as location of spill, spill amount, type of oil, etc. However, ships are designed for global trade, transporting different oil qualities. Therefore, globally applicable criteria must average over most of these factors, and the spill amount is the remaining factor that will be used to measure cost effectiveness against. A weighted, global average cleanup cost of USD 16,000/tonne of oil spilt has been calculated, considering the distribution of oil tanker traffic densities. Finally, the criteria are compared with some existing regulations for oil spill prevention, response and compensation (OPA 90)

Spatial Pattern and Regional Relevance Analysis of the Maritime Silk Road Shipping Network

Directory of Open Access Journals (Sweden)

Naixia Mou

2018-03-01

Full Text Available Under the strategy of “One Belt and One Road”, this paper explores the spatial pattern and the status quo of regional trade relevance of the Maritime Silk Road shipping network. Based on complex network theory, a topological structure map of shipping networks for containers, tankers, and bulk carriers was constructed, and the spatial characteristics of shipping networks were analyzed. Using the mode of spatial arrangement and the Herfindahl–Hirschman Index, this paper further analyzes the traffic flow pattern of regional trade of three kinds of goods. It is shown that the shipping network of containers, tankers and bulk carriers are unevenly distributed and have regional agglomeration phenomena. There is a strong correlation between the interior of the region and the adjacent areas, and the port competition is fierce. Among them, the container ships network is the most competitive in the region, while the competitiveness of the tankers network is relatively the lowest. The inter-regional correlation is weak, and a few transit hub ports have obvious competitive advantages. The ports in Northeast Asia and Southeast Asia are the most significant. The research results combined with the Maritime Silk Road policy can provide reference for port construction, route optimization, and coordinated development of regional trade, which will help to save time and cost of marine transportation, reduce energy consumption, and promote the sustainable development of marine environment and regional trade on the Maritime Silk Road.

The internal surfaces of crude petroleum tankers are subjected to corrosive environments, therefore it is of great importance to research coatings for the protection of those structures. Ceramic materials generally exhibit characteristic chemical inertness and are shown as material option for this application. In this study alumina-titania ceramic composites have been produced and reinforced with yttria. These composites were produced by thermo-mechanical process, sintered at 1350 ° C for 24 hours, and left to cool down in the oven. The structural and microstructural characterization of the sintered material was tested by X-ray diffraction and scanning electron microscopy. And its mechanical property was studied by Vickers microhardness test. After this characterization, the samples underwent a stability test where they were immersed in crude oil at room temperature for 60 days, during which were periodically subjected to tests related to stability, which was found found that the material was free from cracks, fissures or fractures, presenting for these reasons characteristics of inertia when subjected to crude oil environment.

The complex factor of ecological risk and its application for planning the marine transport of crude oil

International Nuclear Information System (INIS)

Goncharov, V.K.

2004-01-01

Computer-controlled methods for scheduling the routes of ships, port calls, and cargo handling are now commonly used for the marine freight transport. This presentation proposed a method for preventing accidents for tanker fleets. The risk of accidental oil spills increases with weather deterioration, particularly in polar waters. It is therefore necessary to correlate the risk of the fixed costs with compensation for environmental damages and repair to facilities. The profits lost while waiting for favourable weather conditions are also considered. The proposed 'complex factor of ecological risk' is intended to improve ecological safety and economic efficiencies of transporting oil by sea in areas with difficult weather conditions. It requires computer simulation which is based on volumes of statistical data of weather in marine areas, emergency incidents with tankers near terminals and the economic aspects of crude oil transportation

Infectious diseases of livestock have negative consequences for animal production as well as animal health and welfare and can be transmitted between farms via direct (live animal movements) as well as indirect (via physical vectors such as, people, transport vehicles and fomites) contacts. The objective of the study was to examine the travel patterns of professionals visiting Swedish farms (veterinarians, milk tanker drivers, artificial inseminators, maintenance technicians and livestock hauliers). This was done by obtaining records of the farms visited by a sample of professionals in the above categories in one week in January, one week in April, one week in July and one week in October in the Swedish counties Västerbotten, Södermanland, Västergötland and Skåne. There were twelve participating organisations, and data was provided for one to three individuals/vehicles/veterinary practices per professional category and per geographic region (except for dairy service technicians and livestock hauliers who did not provide data from all regions). There was a trend towards larger areas covered and smaller number of farms visited per week in the north, but exceptions occurred and there were regional variations. Generally, the greatest areas were travelled by milk tankers and livestock hauliers, and the profession travelling over the smallest areas tended to be the veterinarians. Milk tankers visited most farms per week, one milk tanker could visit between 23 and 90 farms per week and travel over areas between 717 km² and 23,512 km² per week. Valuable insight into the travel patterns of Swedish professionals has emerged although the implications of the study largely concern highly infectious diseases. Movement of live animals pose the greatest risk for the spread of infectious animal diseases; however indirect contacts are important for many diseases. The results of this study indicate that in Sweden a highly contagious disease might spread over a large area in

LNG - Possibility which can't be neglect, v. 16(64)

International Nuclear Information System (INIS)

Stojanovski, Mirko; Stojanovska Darinka

2008-01-01

liquid natural gas or liquid earth gases one of the shapes in which the gas is being transformed because of an easier transport. Besides the parameters that are being controlled (temperature must under -160°C, pressure under 2,5 bars, density approximately 410-500 kg/m 3 depending on the pressure, the temperature and the structure) , the rest of the characteristic are the same as the earth gas. With its transformation in liquid form, the volume is reduced 614 times in relation with the volume under normal conditions. LPG in this shape is mostly used just for the transport ( in special cooled LPG tanker or auto cisterns) and also storage( also in cooled reservoirs). Practically, he provides transport of earthy gas ( LPG tankers, as substitute for gas lines), where there are no gas lines( or at least where it is not affordable). (Author)

Routing and Scheduling Optimization Model of Sea Transportation

Science.gov (United States)

barus, Mika debora br; asyrafy, Habib; nababan, Esther; mawengkang, Herman

2018-01-01

This paper examines the routing and scheduling optimization model of sea transportation. One of the issues discussed is about the transportation of ships carrying crude oil (tankers) which is distributed to many islands. The consideration is the cost of transportation which consists of travel costs and the cost of layover at the port. Crude oil to be distributed consists of several types. This paper develops routing and scheduling model taking into consideration some objective functions and constraints. The formulation of the mathematical model analyzed is to minimize costs based on the total distance visited by the tanker and minimize the cost of the ports. In order for the model of the problem to be more realistic and the cost calculated to be more appropriate then added a parameter that states the multiplier factor of cost increases as the charge of crude oil is filled.

FPSO - floating production storage and off loading -conversion or new build; FPSO - conversao ou construcao nova

2004-07-01

The FPSO technology over the past years has rapidly evolved from tanker based units with classical mooring system to purpose built vessels equipped with dynamic positioning assistance, sophisticated permanent turrets or disconnectable mooring systems. The growth in the number of FPSO's in the 1980's was largely based converted tankers but new-builds now represent 40% of the FPSO fleet. This paper intends to discuss the main technical and economical aspects to be considered when selecting the project for a FPSO construction, including, among others, general and structural conditions for the takers to be converted, safety considerations, systems to be installed and general analysis of engineering design. The study compares construction schedule and the time schedule influence on project conclusion. The evaluation of the designed life time of each vessel an its implications on the project cost and the importance on the decision is also evaluated. (author)

Al-Sulami, A A; Al-Taee, A M R; Yehyazarian, A A

2013-11-01

This study in Iraq investigated the occurrence of Legionella. pneumophila in different drinking-water sources in Basra governorate as well as the susceptibility of isolates to several antibiotics. A total of 222 water samples were collected in 2008-2009: 49 samples from water purification plants (at entry points, from precipitation tanks, from filtration tanks and at exit points), 127 samples of tap water; and 46 samples from tankers and plants supplying water by reverse osmosis. The findings confirmed the presence of L. pneumophila in sources of crude water, in general drinking water supplies and drinking water tankers. Of 258 isolates 77.1% were serotype 1 and 22.9% serotypes 2-15. All examined isolates displayed drug resistance, particularly to ampicillin, but were 100% susceptible to doxycycline. The prevalence of L. pneumophila, especially serogroup 1, is a strong indicator of unsuitability of drinking water and requires appropriate action.

Liquid Sloshing Dynamics

Ibrahim, Raouf A.

2005-06-01

The problem of liquid sloshing in moving or stationary containers remains of great concern to aerospace, civil, and nuclear engineers; physicists; designers of road tankers and ship tankers; and mathematicians. Beginning with the fundamentals of liquid sloshing theory, this book takes the reader systematically from basic theory to advanced analytical and experimental results in a self-contained and coherent format. The book is divided into four sections. Part I deals with the theory of linear liquid sloshing dynamics; Part II addresses the nonlinear theory of liquid sloshing dynamics, Faraday waves, and sloshing impacts; Part III presents the problem of linear and nonlinear interaction of liquid sloshing dynamics with elastic containers and supported structures; and Part IV considers the fluid dynamics in spinning containers and microgravity sloshing. This book will be invaluable to researchers and graduate students in mechanical and aeronautical engineering, designers of liquid containers, and applied mathematicians.

Micro or macro. A case study of approaches to forecasting based on oil trading, 1970-1974

Energy Technology Data Exchange (ETDEWEB)

Scanlan, T

1984-03-01

This paper attempts to survey the events of 1970-1974 in the oil and tanker trades and to analyse the relative merits of macro and micro approaches at the time. There are several reasons why the turbulent events in the world oil and tanker markets, at the beginning of the last decade, are worth analysing. It is 10 years since the major oil crisis of 1973 changed the pattern of events in both industries - and indeed changed the terms of trade between nations. The implications of these changes are still with us today. There are some for whom this is far from clear and who would argue that we have moved from supply constraints in both industries to chronic surplus, that the forecast of increasing scarcity of oil were simply extrapolatory and have not been fulfilled and therefore that looking back a decade has little lasting value for us today.

Development of a cryogenic flexible pipe for the transfer of liquefied natural gas; Mise au point d'un flexible cryogenique pour le transfert du gaz naturel liquefie

Rigaud, J.; Gerez, J.M.; Dieumegard, C. [Coflexip Stena Offshore, 75 - Paris (France)

2000-07-01

For historical reasons, the liquefaction of natural gas is performed with onshore equipments and LNG tanker-ships are loaded and unloaded using rigid articulated arms. When these operations are performed in harbors, the movement of the ship with respect to the pier are relatively limited. Today, several companies aim at liquefying natural gas using floating facilities. The loading of tanker-ships is performed offshore, and thus movements between the ship and the floating facility are enhanced. The use of a flexible pipe can be an interesting alternative solution to the articulated arm. This article describes the state-of-the-art of the LNG flexible technology developed by Coflexip Stena Offshore and the progress of the program of development of a cryogenic flexible: structure, fittings, safety (leaks detection), thermal calculations, optimization of the corrugated hose profile, pressure drops, fatigue tests and service life, materials development, prototype and real tests.

The physico-chemical and microbial quality attributes of untreated water samples from hand dug wells and treated water delivered by tankers (mobile services) were assessed to determine the susceptibility of Amasaman community to water borne diseases. The physico-chemical parameters of all the water sources for domestic use were within the World Health Organization (WHO) drinking water guidelines and Ghana Standards (GS), with the exception of turbidity and colour which showed higher values for the well waters. With respect to the microbial quality, the waters from the hand-dug wells and tanker services showed presence of both total and faecal coliforms, at levels higher than WHO and GS values of zero counts per 100 mL for drinking water. The poor microbial quality (presence of coliform bacteria) of all the water samples suggested susceptibility and exposure of the community to waterborne diseases on continuously drinking the available water.

Full Text Available La coppia criminale è un fenomeno poco comune nell'ambito dei delitti in quanto la maggior parte dei criminali commette il crimine da solo o coinvolge altri individui solo per caso. Ciò nonostante, la letteratura rivela una serie di coppie criminali che hanno commesso diversi crimini, fino ad arrivare all’omicidio. Alcuni hanno ucciso per denaro, altri per odio, altri ancora per amore, per vendetta, per perversione. Bonnie e Clyde, Olindo e Rosa, Erika e Omar sono espressione di un viaggio nel fenomeno del “crimine di coppia” in cui manifestazioni di follia a due, al di là dell’infatuazione reciproca e della dipendenza psicologica, si svuotano di qualsiasi accezione romantica per concretizzarsi in qualcosa di spaventoso e incontenibile, capace di sfuggire ad ogni tipo di catalogazione e comprensione. Nel presente lavoro, in particolare, si andrà ad analizzare la coppia criminale degli autori della strage di Erba, che verrà esaminata nell’ottica della coscienza intersoggettiva di Stern. Le couple criminel est un phénomène rare puisque la majorité des crimes sont commis par des criminels seuls ou ce n’est que par hasard qu’ils impliquent d’autres personnes. Toutefois, la littérature parle d’une série de couples criminels qui ont commis des différents types de crimes (homicide inclus. Certains d’entre eux tuent pour de l’argent, certains autres à cause de la haine, de l’amour, de la revanche ou de la perversion. Bonnie et Clyde, Olindo et Rosa, Erika et Omar constituent des exemples du phénomène du « crime en couple ». Ce sont des situations de folie à deux qui n’ont aucune acception romantique et qui se traduisent en quelque chose d’horrifiant et d’incontrôlé. Dans cet article, les auteurs vont analyser le couple criminel composé par les responsables du massacre de Erba (Italie du Nord.

Maritime Renaissance: oil begins to make up for lost seals and fish

Energy Technology Data Exchange (ETDEWEB)

Reid, W.

2000-12-04

The economic recovery of Newfoundland as a result of success in the Hibernia oilfield off the coast of Newfoundland is discussed. Oil production and the transport of oil from the Hibernia to the mainland by rugged double-hulled tankers that are about five times bigger than any other ship in Canada in terms of carrying capacity is a welcome event, considering that the seal hunt and the fishing industry that formerly provided sustenance to the people of Newfoundland have died as a result of world-wide pressure by animal rights groups, and indiscriminate overfishing. Transport of the crude oil from the Hibernia field is provided by Canship Ugland, a St. John's-based firm which now operates a fleet of three tankers. Each of the three vessels are capable of carrying 850,000 barrels of oil, or more than four times Hibernia's daily production. The 'Vinland' the latest of the three tankers to be commissioned, was built in South Korea, is 272 metres long and 46 metres wide. The ship is expected to carry oil from the rig 315 kms offshore to the Newfoundland Terminal at Whiffen Head, where the oil is picked up by smaller vessels. The 'Vinland' is equipped with the dynamic positioning feature which lets the ship maintain its maneuverability and position even if half her power is lost. The company employs people from all over the province and puts millions of dollars annually into the Newfoundland economy. 1 photo.

Deposition of oil residues, also known as tar balls, is a seasonal phenomenon, and it occurs only in the southwest monsoon season along the west coast of India. This has become a serious environmental issue, as Goa is a global tourist destination. The present work aims at identifying the source oil of the tar balls that consistently depositing along the Goa coast using multi-marker fingerprint technique. In this context, the tar ball samples collected in May 2013 from 9 beaches of Goa coast and crude oils from different oil fields and grounded ship were subject to multi-marker analyses such as n-alkanes, pentacyclic terpanes, regular steranes, compound specific isotope analysis (CSIA) and principle component analysis (PCA). The n-alkane weathering index shows that samples have been weathered to various degrees, and the status of weathering is moderate. Since the international tanker route passes closer to the west coast of India (WCI), it is generally presumed that tanker wash is the source of the tar balls. We found that 2010/2011 tar balls are as tanker wash, but the present study demonstrates that the Bombay High (BH) oil fields can also contribute to oil contamination (tar balls) along ≈ 650 km stretch of the WCI, running from Gujarat in the north to Goa in the south. The simulated trajectories show that all the particles released in April traveled in the southeast direction, and by May, they reached the Goa coast with the influence of circulation of Indian monsoon system.

Box model of radionuclide dispersion and radiation risk estimation for population in case of radioactivity release from nuclear submarine number-sign 601 dumped in the Kara Sea

International Nuclear Information System (INIS)

Yefimov, E.I.; Pankratov, D.V.; Ignatiev, S.V.

1997-01-01

When ships with nuclear reactors or nuclear materials aboard suffer shipwreck or in the case of burial or dumping of radioactive wastes, atmospheric fallout, etc., radionuclides may be released and spread in the sea, contaminating the sea water and the sea bottom. When a nuclear submarine (NS) is dumped this spread of activity may occur due to gradual core destruction by corrosion over many years. The objective of this paper is to develop a mathematical model of radionuclide dispersion and to assess the population dose and radiation risk for radionuclide release from the NS No. 601, with Pb-Bi coolant that was dumped in the Kara Sea

2010-07-01

We present the first documented case of severe burns, sustained by a diver as a result of auto-ignition of air-activated heat packs at high partial pressure of oxygen and high ambient pressure. Our patient was diving the shipwreck of The Lusitania off the south coast of Ireland. This is a significant wreck, lying 90 metres down on the seabed. Torpedoed by a German U-boat in 1915, its loss prompted American involvement in WW1. Several unlikely events combined in this case to bring about serious and life threatening injuries. Herein we discuss the case and explore some of the physical and chemical processes that lead to these injuries.

Report of the BC [British Columbia] Citizens Advisory Committee on Oil Spill Prevention and Response

International Nuclear Information System (INIS)

1992-01-01

The British Columbia Citizens Advisory Committee on Oil Spill Prevention and Response was established in 1991 to advise the provincial government of public concerns over oil spill prevention, preparedness, and response. The Committee also monitors provincial and joint provincial/western USA initiatives in the area. The Committee notes that the volume of oil tanker traffic through navigationally risky passages along the British Columbia coast is large and that prevention is the most useful method in dealing with oil spills. Committee concerns are summarized in the areas of government committment, design and construction of oil tankers and barges, oil spill issues related to ports, the Low Point Terminal proposal, waste oil collection and disposal, spill response capability, the Strait of Georgia Oil Spill Response Information System, the use of volunteer auxiliaries and the Youth Corps in oil spill response, wildlife rescue and rehabilitation, coordination of response activities, and the future of the Committee. Recommendations to the government are made with respect to the aforementioned areas of concern

The cost of CPO’s transport from one area to CPO’s factory located at the port of destination may affect the level of CPO’s prices and the number of demands. In order to maintain the availability of CPO a strategy is required to minimize the cost of transporting. In this study, the strategy used to select kind of charter ships as barge or chemical tanker. This study aims to determine an optimization model for strategy decision support in selecting kind of CPO’s ship by minimizing costs of transport. The select of ship was done randomly, so that two-stage stochastic programming model was used to select the kind of ship. Model can help decision makers to select either barge or chemical tanker to distribute CPO.

Meteorological aspects of benzene transport, dispersion and personal exposure in Valdez, Alaska

Energy Technology Data Exchange (ETDEWEB)

Murray, D.R.; Ball, R.J. [TRC Environmental Corp., Windsor, CT (United States)

1994-12-31

The Valdez Air Health Study (VAHS) was conducted in Valdez, Alaska to determine the personal exposure of the residential population of Valdez to certain volatile organic compounds (VOCs). The VAHS used the EPA`s Total Exposure Assessment Methodology (TEAM) with continuous meteorology, air quality and intense tracer measurements to monitor personal and indoor/outdoor concentrations of VOCs in the community. The Valdez fjord is the site of the Alyeska Marine Terminal, the largest crude oil loading terminal in the United States, with a maximum capacity of 2.2 million barrels per day. The Alyeska Marine Terminal is the transfer point for Prudhoe Bay crude oil from the pipeline to marine tankers. During 1990, the terminal and marine tankers were estimated to emit approximately 450 metric tonnes/year of benzene to the air at an average throughput of 1.8 million barrels/day while benzene emissions from other sources in the basin were estimated to be approximately 3 tonnes/year.

A guide to contingency planning for oil spills on water. V. 2

International Nuclear Information System (INIS)

1997-01-01

The movement of oil from the dominant production centres of the world to the world-wide market is primarily achieved by the use of tankers and pipelines. The global pattern of marine transport is well established as shown in Figure 1, below. While the environmental priority for all tanker operations is the prevention of spills, it is recognized that marine spills are a factor for which management must plan. This report, which is prepared for those managements in industry and government, describes the elements of the contingency planning process. It stresses the importance of cooperative activity between industry and government. It presents a consensus view of the IPIECA membership which is representative of the international oil industry. It reflects current informed thinking in the light of the extensive individual company and industry organization reviews that have taken place since the Exxon Valdez and other major incidents in 1989/90. This report has drawn freely on many of these reviews, some of which have been published. (UK)

IMCO: Making the seas safer and cleaner

International Nuclear Information System (INIS)

1979-01-01

Since 1959, when the IMCO Assembly met for the first time, the Organization has had two main objectives: the introduction of measures designed to improve safety at sea and to prevent pollution of the sea from ships. But during its twenty-year history IMCO has also adopted a number of Conventions and other measures which are aimed specifically at tankers and the problem of pollution. The 1954 Oil Pollution Convention (for which IMCO became depositary in 1959) was the first major attempt by the maritime nations to curb the impact of oil pollution, but since then the problem has become even more serious today The amount of oil carried by sea has risen by 700 per cent in 20 years - to around 1,700 million tons. The world tanker fleet has increased from 37 million deadweight tons in 1954 to around 340 million deadweight tons today, and the size of the tankers themselves has also grown amazingly. The second Convention deals with liability of the ship or cargo owner for damage suffered as a result of an oil pollution casualty. The Convention is intended to ensure that adequate compensation is available to victims and places the liability for the damage on the shipowner. As a result, another Conference was convened by IMCO in 1971 which resulted in the adoption of a Convention establishing the International Fund for Compensation for Oil Pollution Damage The Convention came into force in 1978 and the Fund has now been established with its headquarters in London These three Conventions all deal with what one might call the legal aspects of oil pollution. But the continuing boom in the transportation of oil showed that more work needed to be done on the technical side as well: the scale of oil pollution was so great in some areas that there was serious concern for the marine environment, not only as a result of accidents but through normal tanker operations, notably the cleaning of cargo tanks. In 1973 a major conference was called to discuss the whole problem of marine

Nuevas aportaciones a la gestión informatizada de derrames de hidrocarburos: su aplicación a “zonas refugio”

Full Text Available The purpose of this paper is to describe most of the procedures to follow in deciding whether you should transfer a tanker wrecked in a "refuge zone". In reaching this decision, it should consider different procedures, in order to objectify the best decision. It is important to know very well the features and infrastructures of the different coastal areas, which can be considered as possible "refuge zones". Based on the foregoing analysis, it has developed a program consisting of several modules to permit compute data of great importance, among which include matrices of environmental and infrastructural values that allow for the calculation of certain factors for transfer actions and preparation of the tanker (transfer time of the tanker, berthing time and connection time to the pumping systems, time of emptying the oil in storage tanks, transfer to another tanker, etc. In addition, this program allows us to estimate the costs of cleaning and restoration, as well as losses in the tourism sector.

An investigation of the stable isotopes, geochemistry and morphology of major streams in Dominica, Lesser Antilles: 2014 - 2017

Science.gov (United States)

Kopas, D. C.; Joseph, E. P.; Frey, H. M.

2017-12-01

The island of Dominica is a recently active (pH and temperature, were recorded and water samples taken and analyzed for alkalinity, major elements (cations and anions), trace elements and stable isotopes (carbon, deuterium, and oxygen). Variations in water chemistry and river morphology were compared to various parameters, including precipitation, landslide locations, and lithology for each of the catchments. Within the study period, on August 27th, 2015, a significant tropical storm, Erika, made landfall in Dominica, depositing more than 500 mm of rainfall in 10 hours. There was little infiltration of the rainwater (over 50-60% run-off), which resulted in significant landslides, flash floods and damage to infrastructure and loss of life. Despite the obvious morphologic changes to the streams and high discharge during the storm event, preliminary analysis has shown little change in major stream geochemistry following the passage of Tropical Storm Erika. The 10-month time gap between the storm and the post-storm field sampling in June 2016 may be a factor of why geochemical changes were not observed. One of the most significant variations of stream composition during the study period was annual shifts in δD between -1.3 to -5.8 ‰ and δ18O between -1.98 to -2.61 ‰. A possible factor influencing the δ18O of surface waters is seasonal variation in rainfall. The dominant control on precipitation δ18O values is the amount effect, whereby rainfall amount and δ18O are inversely correlated. This relationship is a proxy for changes in δ18O values of surface waters. The data also suggest that hydrothermal fluids are not a prominent contributor to Dominican rivers, despite the presence of active volcanism and numerous hydrothermal systems on the island. The exceptions are the White River, which drains the Valley of Desolation and Boiling Lake and the Lamothe River, which drains the Cold Soufrierre.

Full Text Available En noviembre de 2002, un petrolero obsoleto, el Prestige, naufragó y vertió su carga en las costas de Galicia (noroeste de la Península Ibérica. Este accidente originó un "experimento" social indeseado pero valioso para comprender cómo se representa socialmente la experiencia catastrófica de los "riesgos manufacturados". Este artículo analiza la respuesta del sistema educativo regional a la catástrofe desde dos puntos de vista: a su comprensión en el marco de la respuesta social crítica y proactiva ante los intentos oficiales de representar una "no-catástrofe" y, b el papel de la Educación Ambiental (EA como praxis pedagógica cuya dimensión política se revela como indispensable. La tesis que defendemos es que la naturaleza política de la EA, muchas veces sólo implícita y otras negada explícitamente, se redescubre aquí como eje primordial en la respuesta del sistema educativo y de otros agentes educadores. En este sentido, la catástrofe no ha sido sólo ecológica, sino también, y sobre todo, social y política al cuestionar la globalización económica - su causa radical - y poner en evidencia la vulnerabilidad de las administraciones, incapaces de prevenir o mitigar su impacto sobre el ambiente y las comunidades humanas. En este escenario, la EA contribuye a reflexionar sobre el origen de la catástrofe como consecuencia inesperada de la "modernidad avanzada", en sintonía con el análisis que hace Ulrich Beck sobre la "sociedad del riesgo" y sobre el potencial politizador de las sucesivas catástrofes - la punta del iceberg - en las que el nuevo ethos social se manifiesta y construye.In November 2002, the Prestige, an obsolete oil tanker, sank and spilled her cargo offshore Galicia (in the northwest of the Iberian Peninsula.

Review: Rusticle Formation on the RMS Titanic and the Potential Influence of Oceanography

Science.gov (United States)

Salazar, Maxsimo; Little, Brenda

2017-04-01

Meter length iron-rich rusticles on the RMS Titanic contain bacteria that reportedly mobilize iron from the ship structure at a rate that will reduce the wreck to rust in decades. Other sunken ships, such as the World War II shipwrecks in the Gulf of Mexico (GOM) are also similarly covered. However, at the GOM sites, rusticles are only centimeters in length. Minimal differences in water temperature (a few °C) between the two sites and comparable exposure times from wreckage to discovery cannot rationalize the extreme differences in rusticle length. One possible explanation for the observed difference in rusticle size is the differing amounts of dissolved or colloidal iron at the two locations.

Environmental impact analysis; the example of the proposed Trans-Alaska Pipeline

Science.gov (United States)

Brew, David A.

1974-01-01

The environmental impact analysis made as required by the National Environmental Policy Act of 1969 for the proposed trans-Alaska pipeline included consideration of the (1) technologically complex and geographically extensive proposed project, (2) extremely different physical environments across Alaska along the proposed route and elsewhere in Alaska and in Canada along alternative routes, (3) socioeconomic environment of the State of Alaska, and (4) a wide variety of alternatives. The analysis was designed specifically to fit the project and environment that would be affected. The environment was divided into two general parts--natural physical systems and superposed socioeconomic systems--and those parts were further divided into discipline-oriented systems or components that were studied and analyzed by scientists of the appropriate discipline. Particular attention was given to potential feedback loops in the impact network and to linkages between the project's impacting effects and the environment. The results of the analysis as reported in the final environmental impact statement were that both unavoidable and threatened environmental impacts would result from construction, operation, and maintenance of the proposed pipeline system and the developments related to it. The principal unavoidable effects would be (1) disturbances of terrain, fish and wildlife habitat, and human environs, (2) the results of the discharge of effluent from the tanker-ballast-treatment facility into Port Valdez and of some indeterminate amount of oil released into the ocean from tank-cleaning operations at sea, and (3) the results associated with increased human pressures of all kinds on the environment. Other unavoidable effects would be those related to increase of State and Native Corporation revenues, accelerated cultural change of the Native population, and extraction of the oil and gas resource. The main threatened environmental effects would all be related to unintentional oil

The potential for spills and leaks of contaminated liquids from shale gas developments.

Science.gov (United States)

Clancy, S A; Worrall, F; Davies, R J; Gluyas, J G

2018-06-01

Rapid growth of hydraulic fracturing for shale gas within the USA and the possibility of shale developments within Europe has created public concern about the risks of spills and leaks associated with the industry. Reports from the Texas Railroad Commission (1999 to 2015) and the Colorado Oil and Gas Commission (2009 to 2015) were used to examine spill rates from oil and gas well pads. Pollution incident records for England and road transport incident data for the UK were examined as an analogue for potential offsite spills associated with transport for a developing shale industry. The Texas and Colorado spill data shows that the spill rate on the well pads has increased over the recorded time period. The most common spill cause was equipment failure. Within Colorado 33% of the spills recorded were found during well pad remediation and random site inspections. Based on data from the Texas Railroad Commission, a UK shale industry developing well pads with 10 lateral wells would likely experience a spill for every 16 well pads developed. The same well pad development scenario is estimated to require at least 2856 tanker movements over two years per well pad. Considering this tanker movement estimate with incident and spill frequency data from UK milk tankers, a UK shale industry would likely experience an incident on the road for every 12 well pads developed and a road spill for every 19 well pads developed. Consequently, should a UK shale industry be developed it is important that appropriate mitigation strategies are in place to minimise the risk of spills associated with well pad activities and fluid transportation movements.

Factors influencing the development of routes for regular oil transport from Dikson

Many oil and gas companies have increased their exploration efforts in the Arctic where a considerable part of the world's remaining oil and gas resources are located. Several large fields have been discovered in areas far from markets. This paper described the challenge of finding methods for efficient, reliable and economic transport to markets. Traditionally, shipping operations in Arctic waters has taken place by using icebreakers. However, large scale development of oil and gas fields in the Arctic will require large tankers that are designed for operation under severe Arctic conditions. For that reason, Statoil initiated a program in 2005 to study the operation of large tankers in ice infested waters and under Arctic conditions. The primary objective was to demonstrate that large vessels could operate in ice infested waters and to study the effect of using vessels with large beams. Factors influencing the design of the vessels used for reliable year-round oil transportation by ships from the north-western Russian Arctic areas were investigated with special attention to one icebreaker escorting tanker with wider beam than that of the icebreaker; passage through pressurized ice fields; and, passage through ridge fields. The design of the whole transport system was described in this paper along with an investigation of the physics of the above factors. An ice model tank at the Helsinki University of Technology was used to carry out the tests for oil transport from a possible terminal in the vicinity of the port of Dikson to Murmansk. Three types of winter/ice conditions were analyzed, notably mild, average and severe. For each of these conditions, the parameters of the ice cover were determined along the whole route. The average transport speed was determined based on the ice conditions and ship characteristics for the whole route from Dikson to Murmansk and return. 2 refs., 14 figs.

The discharge sites of processed wastewater was reuse (2%, sewer (52% and absorption well (46%. Discharge sites of exiting effluent from pretreatment units in the industrial park, included sewer (85.5%, transport by tanker (7.1% and absorption well (7.1%. The type of pretreatment process in 35.7% of the industries was chemical and in 64.3%, it was septic tank. Conclusion: The results of this study showed that pre-treatment is not done in most industries and wastewater reuse is performed in few industries. The main method of wastewater disposal in industries was by discharge into the sewer and absorbent well.

Exxon Valdez controversy revived

International Nuclear Information System (INIS)

Anon.

1993-01-01

Four years after its occurrence rocked the petroleum industry and revitalized the US environmental movement, the Exxon Valdez tanker oil spill off Alaska continues to stir controversy. Conflicting reports abound over whether there is long term damage to the Prince William Sound ecosystem resulting from the March 24, 1989, spill. Government scientists at recent conferences disclosed studies they contend show long term, significant damage to the sound. Exxon this month launched a counteroffensive, disclosing results of studies it funded that it claims show no credible scientific evidence of long term damage. At the same time, the company blasted as flawed the government's data on assessing environmental damage to the sound and charged that test samples from the sound were mishandled. Meantime, Prince William Sound still shows lingering effects from the Exxon Valdez oil spill. But recovery has been so rapid that there is more controversy over how to use $900 million in natural resource recovery funds that Exxon paid than over how badly species are suffering. The paper describes Exxon's studies; faulty data; lingering damage; and an update on tanker safety

Finland's oil, chemicals, and energy company, Neste, has achieved an enviable standard of logistics serving the markets around the Baltic Rim. Neste's safe and efficient transportation services are handled by its own fleet of tankers, time-chartered vessels, contract road tankers, and rail. Neste's terminals play an important part in the company's logistics network. The company operates four terminals of its own in Finland, and works with other oil companies at three of their terminals. Neste's own terminals are located at the company's refineries at Porvoo and Naantali, and at Kokkola and Kemi on the Gulf of Bothnia. Outside Finland the completion of a new terminal at Riga in Latvia, to enhance the logistics services provided to Neste's network of service stations and direct sales customers in the Baltic countries. This joins a terminal at Muuga near Tallinn in Estonia, which has been operational for some five years. Construction work began on a terminal in St. Petersburg in December 1997 to serve customers in the St. Petersburg and Vyborg areas. Completion is scheduled for autumn 1999

Energy Technology Data Exchange (ETDEWEB)

Nakata, Y.; Otsuka, M.; Ozawa, H.; Konosu, M. [Mitsui Engineering and Shipbuilding Co. Ltd., Tokyo (Japan)

1997-08-01

A compact and lightweight underwater RTV robot (RTV-SHIP) that enables the remote sensing in the double-shell structure of a tanker and the six-freedom motion control was developed based on the technology of the conventional portable underwater robot. The motion performance test in a water tank showed that the RTV-SHIP can freely access the manhole in the double-shell structure of a tanker and completely satisfies the thrust and swing force required for movement and measurement in a tank. The in-tank function confirmation test also shows that the main measurement items such as positioning in the tank, large deflection of panels, and plate thickness have a satisfactory measurement accuracy and that the RTV-SHIP has the same tone discrimination function as for a visual check. The method of inputting the tank shape during measurement and miniaturizing the recording unit should be improved until the RTV-SHIP is put to practical use. This system can be widely used by improving the above points according to the result of a future measurement test for the actual ships. 1 ref., 9 figs.

Comparing sediment quality in Spanish littoral areas affected by acute (Prestige, 2002) and chronic (Bay of Algeciras) oil spills

Morales-Caselles, C.; Kalman, J.; Riba, I.; DelValls, T.A.

2007-01-01

The quality of sediments collected from two areas of the Spanish coast affected by different sources of contaminants has been compared in this study. The areas studied are the coast of Galicia affected by the oil spill from the tanker Prestige (November 2002) and the Gulf of Cadiz which suffers continuous inputs of contaminants from industries located in the area and from oil spills. Contamination by several chemicals (metals, PCBs and PAHs) that bind to sediments was analyzed, and two toxicity tests (Microtox[reg]) and amphipod 10-day bioassay) were conducted. PAHs were identified as the compounds responsible for the toxic effects. Results show differences between an acute impact related to the sinking of the tanker Prestige and the chronic impact associated with continuous oil spills associated with the maritime and industrial activities in the Bay of Algeciras, this being the most polluted part of the two coastal areas studied in this work. - Littoral sediments affected by low or moderated but continuous oil spills are more polluted than those affected by accidental oil spills such as the Prestige

Incident of oil leakage and theft in oil tank often happens. To prevent it, the liquid volume insides the tank needs to be monitored continuously. Aim of the study is to calculate the liquid volume inside oil tank on any road condition and send the volume data and location data to the user. This research use some ultrasonic sensors (to monitor the fluid height), Bluetooth modules (to sent data from the sensors to the Arduino microcontroller), Arduino Microcontroller (to calculate the liquid volume), and also GPS/GPRS/GSM Shield module (to get location of vehicle and sent the data to the Server). The experimental results show that the accuracy rate of monitoring liquid volume inside tanker while the vehicle is in the flat road is 99.33% and the one while the vehicle is in the road with elevation angle is 84%. Thus, this system can be used to monitor the tanker position and the liquid volume in any road position continuously via web application to prevent illegal theft.

Oil spill risk assessment in maritime transportation networks

International Nuclear Information System (INIS)

Yudhbir, L.; Iakovou, E.

2005-01-01

Commercial shippers and regulatory agencies face the challenge of evaluating the merits of various alternative policies for the transportation of crude oil and petroleum products. This paper presented a new risk estimation and assignment methodology that assesses the risk costs for the bodies of water where shipping lanes exist. The methodology is based on historical spills and uses causal data to estimate risk cost between 2 points of reference for numerous products transported by a variety of vessels. In response to public concerns regarding the environmental impacts of accidental spills from tanker ships, laws have been imposed on companies for all costs relating to environmental damage. This measure has prompted the oil industry to take greater responsibility, but a better understanding of tanker re-routing on environmental sensitive areas is needed in order to implement detailed emergency response plans and greater safety precautions. This methodology addressed the need for an efficient maritime transportation system that provides routing for various vessels carrying different petroleum products. The risk estimation methodology successfully modeled a multi-objective, multi-commodity routing problem. 23 refs., 3 figs

The Archaeology of the Nautical Astrolabe: News from a Shipwreck in Namibia

Science.gov (United States)

Pereira, José Manuel Malhão

2015-05-01

Being a sailor, astronomy has always been present in my life and I confess it has been a love affair, but during the last decades of the 20th century something terrible happened. Satellites invaded our lives, and with Navistar and GPS all the romance has gone! Nowadays what remains is history and historians, and fortunately they are here in great number and quality. If we speak about European maritime expansion we will always find the astrolabe as its symbol. This instrument (the adaptation for use at sea of the well known, planispheric astrolabe), although very simple, demonstrates that what is needed at sea is the simplest way to perform the difficult task of knowing the ship's position, or at least its latitude, with sufficient accuracy. Simple as it is, it has been in use for more than a century and a half, and its physical characteristics were known mainly on account of maritime archaeological findings. When David Waters published his work on the mariner's astrolabe (1966), the Department of Navigation and Astronomy of the National Maritime Museum in Greenwich listed 21 astrolabes. But Waters in fact listed only 19 when he read his paper in Coimbra. Some years later, in 1983, in Lagos, Portugal, Alan Stimson read his important paper during the IVth International Reunion for the History of Nautical Science and Hydrography, entitled "The Mariner's Astrolabe, a Survey of 48 Surviving Examples". Five years later his well known book, (that became a classical reference on the subject) already listed 66 instruments, 23 of them being of Portuguese origin. Captain Estácio dos Reis, an internationally accepted authority for the study of the mariner's astrolabe and other instruments has deeply studied this subject and published a vast number of works on it (see, for example, "Medir Estrelas", 1977). He is the person responsible for Portugal being the country that has the largest number of marine astrolabes in its museums. The purpose of my paper is to summarise the situation since that time and, mainly, to call scholars' attention to the importance of marine archaeology for the history of navigation and astronomy applied to navigation. The audience will be informed, in some detail, about a recent finding in Namibia of a wreck of a Portuguese ship, which grounded near the mouth of the Orange River on its way to India. The remains of that ship and its cargo, which have been preserved by the sands of the southwest African coast, are awaiting the investigation of experts. It contains probably the most ancient astrolabes found so far.

Norwegian concern over strongly increased Russian oil transport along the Norwegian coast

International Nuclear Information System (INIS)

2003-01-01

The transport of oil from the northern parts of Russia along the coast of Norway will multiply in a few years. An analysis has shown that the risk of a shipwreck followed by pollution will then increase dramatically. The coastal population of North Norway has begun to demand that measures be taken, and they are backed by the military authorities, who say the preparedness must be considerably improved. Massive oil spills are not the only danger. Spills of ballast water from ships have introduced foreign species that disrupts the local eco systems. A number of bilateral agreements exist between Norway and Russia on prevention and notification of accidents, cooperative rescue work and environmental work. These agreements do not fully satisfy the need for notification and warning, however

In recent years, the number of biotech enterprises in Europe has grown spectacularly, largely fueled by the increasing number of entrepreneurial initiatives from Europe's leading research institutes. The place held on the economic market by these enterprises, is a question that market analysts have been asking themselves since their rapid growth and, more particularly, their over valuation which, at times, has led to the crash of their shares on the stock markets. To be sure, this article does not claim to go into an in-depth financial analysis to explain the details of certain "shipwrecks". Rather, it just would like to provide some useful indications for all those having embarked, or desirous of doing so, in the creation of biomedical enterprises.

Turning round the tanker: oil companies and corporate social responsibility

International Nuclear Information System (INIS)

1999-01-01

This article focuses on the conversion of oil companies to Corporate Social Responsibility (CSR), and their dialogue with charities after their reputations plummeted earlier in this decade, and traces this change in corporate culture and the restructuring of toil company operations to take into account CSR. The growing business for CSR consultants and ethical investment companies, the role of charities such as Oxfam in promoting CSR, the fact that most of the world major oil reserves are in countries with human rights problems, the potency of peer pressure, and the competitive disadvantages now attached to companies having a negative impact are discussed. It is questioned whether the cultural transformation is just another PR exercise, and the unbridgeable gap between environmentally friendly operations advocated by Greenpeace and oil company operations, and the CSR performance of the oil giants are considered. Details of the Nigerian experience, codes for companies, and the views of Greenpeace and Amnesty are given. (UK)
