The inter-regional incidents associated with the oil spill is increasingly a serious problem to the industrial developing countries, like Vietnam. In this study, a multi-criteria analysis process was proposed to identify petroleum depots that represent potential inter-regional oil spill incidents in Ho Chi Minh City and the neighboring provinces. The criteria for determining the inter-regional inccidents asscociated with oil spill comprise of a number of criteria sets such as oil spill hazard criteria, inter-regional hazard criteria, oil spill damage criteria. Hierarchical analysis (AHP) has been applied for identifying the importance factor of the criteria. The total risk of inter-regional oil spill incidents are then estimated to provide effective support to the risk management and response plan.

ABSTRACT Every nation faces the possibility of a major natural disaster and few plans are in place to deal with the massive consequences that follow. When Hurricane Katrina reached landfall, the human toll and extent of damage made it the worst natural disaster in American history. The news headlines were filled with the images of desperation and the efforts of the thousands of heroes across the spectrum of government who worked tirelessly to help the citizens of the Gulf Coast of the United States recover. Less visible to the American public was the vast environmental impact caused by millions of gallons of oil released by hundreds of individual oil spills. The total oil volume lost to the environment is estimated at over 8.2 million gallons, making it the second largest oil spill in United States history. Moreover, this spill was the first major environmental disaster managed under the newly published National Response Plan, a plan developed following the tragic events of the terrorist attacks of September 11, 2001. This paper will describe how response managers overcame the incredible challenges of managing multiple oil spills in an enormous area devoid of the support infrastructure, human resources and the logistics network normally present in major spills within the United States. The authors will offer a first hand account of the strategies employed by the response management system assembled to combat the spills. They will describe key lessons learned in overcoming competition for critical resources; the importance of combining scientific, legal and other support in determining response options such as burning and debris removal; and the methodology employed in creating a Unified Area Command that included multiple responsible parties. Finally, this paper will provide insights to processes within the Joint Field Office, an element of the National Response Plan, and how well it performed in supporting response efforts.

ABSTRACT The Humber is one of Britain's major estuaries, the water catchment area being some 20 percent of England, including a major proportion of British industrial activity. Despite this the Humber is not severely polluted, indeed large areas of the shoreline are designated sites of scientific interest while other areas are nature reserves. The extensive mudflats and salt marsh areas within the Humber estuary are of international importance for a number of bird species, particularly during the winter months. In addition there are areas of high amenity value. Two main oil terminals are operated within the estuary, the Tetney Monobuoy and the Immingham Oil Terminal. Both receive crude oil from tankers while the latter exports petroleum products. Both these sites are potential sources of oil spills, as was highlighted by the Sivand incident in September 1983. The paper identifies the sensitive areas of the Humber in terms of biological and amenity/commerical values, to produce an environmental contingency/oil spill response plan. The basis of the plan was to obtain samples for the assessment of sediment chemistry and biology if an incident occurred, prior to oil beaching, with a view to updating the present data base. The updated assessment can then be used to produce a detailed appraisal of any damage to the Humber environment. The paper includes an overview of the response plan structure.

ABSTRACT The Coast Guard's oil spill removal organization (OSRO) classification process underwent significant revision in late 1995. The revision was necessary to strengthen the program into a more credible and useful tool for facilitating preparation and review of vessel and facility response plans. The revised process is more closely linked to the response planning criteria that vessel and facility owners and operators are required to meet under the Oil Pollution Act of 1990. As a result, the process provides a better indication of an OSRO's capacity and potential to respond to and recover oil spills of various sizes. Data provided by each OSRO are being included in the computer-based national Response Resource Inventory (RRI). The paper describes the important features and limitations of the revised classification process and gives an interpretation of what the new classifications mean to response plan holders and reviewers. It also describes the method by which plan holders can use the computer-based RRI as a tool to conduct their own analysis of an OSRO's capacity to meet their specific planning requirements.

International experience of oil spill response in the sea defines the priority of coastal protection and the need to identify as most valuable in ecological terms and the most vulnerable areas. Methodological approaches to the assessing the vulnerability of Arctic coasts to oil spills based on international systems of Environmental Sensitivity Index (ESI) and geomorphological zoning are considered in the article. The comprehensive environmental and geomorphological approach allowed us to form the morphodynamic basis for the classification of seacoasts and try to adapt the international system of indexes to the shores of the Kara Sea taking into account the specific natural conditions. This work has improved the expert assessments of the vulnerability and resilience of the seacoasts.

A field study was carried out involving seven fixed sampling stations. The sampling locations were selected to cover the distribution of pollutants in the Shuaiba Industrial Area (SIA), which was contaminated with oil released from oil wells and broken pipelines and with a vast amount of burnt and unburnt crude oil from the burning and gushing oil wells. The samples were collected biweekly between July 1993 and July 1994. The concentrations of V, Ni, Cr, Cd and Pb were determined and compared with the previously collected baseline data to assess the degree of environmental damage caused due to the oil spills during the Gulf war. The average concentrations (mg/kg) of various elements in the marine sediment were 17.3 for V, 30.8 for Ni, 55.5 for Cr, 0.02 for Cd and 1.95 for Pb. Our results show that even after the heavy spillage of oil, associated metal concentrations were not very high compared with previously reported base line values.

The Baltic Sea is a unique and sensitive brackish-water ecosystem vulnerable to damage from shipping activities. Despite high levels of maritime safety in the area, there is a continued risk of oil spills and associated harmful environmental impacts. Achieving common situational awareness between oil spill response decision makers and other actors, such as merchant vessel and Vessel Traffic Service center operators, is an important step to minimizing detrimental effects. This paper presents the Next-Generation Smart Response Web (NG-SRW), a web-based application to aid decision making concerning oil spill response. This tool aims to provide, dynamically and interactively, relevant information on oil spills. By integrating the analysis and visualization of dynamic spill features with the sensitivity of environmental elements and value of human uses, the benefits of potential response actions can be compared, helping to develop an appropriate response strategy. The oil spill process simulation enables the response authorities to judge better the complexity and dynamic behavior of the systems and processes behind the potential environmental impact assessment and thereby better control the oil combat action.

A set of open-source routines capable of identifying possible oil-like spills based on two random forest classifiers were developed and tested with a Sentinel-1 SAR image dataset. The first random forest model is an ocean SAR image classifier where the labeling inputs were oil spills, biological films, rain cells, low wind regions, clean sea surface, ships, and terrain. The second one was a SAR image oil detector named “Radar Image Oil Spill Seeker (RIOSS)”, which classified oil-like targets. An optimized feature space to serve as input to such classification models, both in terms of variance and computational efficiency, was developed. It involved an extensive search from 42 image attribute definitions based on their correlations and classifier-based importance estimative. This number included statistics, shape, fractal geometry, texture, and gradient-based attributes. Mixed adaptive thresholding was performed to calculate some of the features studied, returning consistent dark spot segmentation results. The selected attributes were also related to the imaged phenomena’s physical aspects. This process helped us apply the attributes to a random forest, increasing our algorithm’s accuracy up to 90% and its ability to generate even more reliable results.

AbstractIn order to assess the potential impact from oil spills and decide the optimal response actions, prediction of population level effects of key resources is crucial. These assessments are usually based on acute toxicity data combined with precautionary assumptions because chronic data are often lacking. To better understand the consequences of applying precautionary approaches, two approaches for assessing population level effects on the Arctic keystone species polar cod (Boreogadus saida) were compared: a precautionary approach, where all exposed individuals die when exposed above a defined threshold concentration, and a refined (full-dose-response) approach. A matrix model was used to assess the population recovery duration of scenarios with various but constant exposure concentrations, durations and temperatures. The difference between the two approaches was largest for exposures with relatively low concentrations and short durations. Here, the recovery duration for the refined approach was less than eight times that found for the precautionary approach. Quantifying these differences helps to understand the consequences of precautionary assumptions applied to environmental risk assessment used in oil spill response decision making and it can feed into the discussion about the need for more chronic toxicity testing. An elasticity analysis of our model identified embryo and larval survival as crucial processes in the life cycle of polar cod and the impact assessment of oil spills on its population.

Marine oil spills occur suddenly and pose a serious threat to ecosystems in coastal waters. Oil spills continuously affect the ocean environment for years. In this study, the oil spill caused by the accident of the Sanchi ship (2018) in the East China Sea was hindcast simulated using the oil particle-tracing method. Sea-surface winds from the European Centre for Medium-Range Weather Forecasts (ECMWF), currents simulated from the Finite-Volume Community Ocean Model (FVCOM), and waves simulated from the Simulating WAves Nearshore (SWAN) were employed as background marine dynamics fields. In particular, the oil spill simulation was compared with the detection from Chinese Gaofen-3 (GF-3) synthetic aperture radar (SAR) images. The validation of the SWAN-simulated significant wave height (SWH) against measurements from the Jason-2 altimeter showed a 0.58 m root mean square error (RMSE) with a 0.93 correlation (COR). Further, the sea-surface current was compared with that from the National Centers for Environmental Prediction (NCEP) Climate Forecast System Version 2 (CFSv2), yielding a 0.08 m/s RMSE and a 0.71 COR. Under these circumstances, we think the model-simulated sea-surface currents and waves are reliable for this work. A hindcast simulation of the tracks of oil slicks spilled from the Sanchi shipwreck was conducted during the period of 14–17 January 2018. It was found that the general track of the simulated oil slicks was consistent with the observations from the collected GF-3 SAR images. However, the details from the GF-3 SAR images were more obvious. The spatial coverage of oil slicks between the SAR-detected and simulated results was about 1 km2. In summary, we conclude that combining numerical simulation and SAR remote sensing is a promising technique for real-time oil spill monitoring and the prediction of oil spreading.

AbstractMicrobiomes of freshwater basins intended for human use remain poorly studied, with very little known about the microbial response to in situ oil spills. Lake Pertusillo is an artificial freshwater reservoir in Basilicata, Italy, and serves as the primary source of drinking water for more than one and a half million people in the region. Notably, it is located in close proximity to one of the largest oil extraction plants in Europe. The lake suffered a major oil spill in 2017, where approximately 400 tons of crude oil spilled into the lake; importantly, the pollution event provided a rare opportunity to study how the lacustrine microbiome responds to petroleum hydrocarbon contamination. Water samples were collected from Lake Pertusillo 10 months prior to and 3 months after the accident. The presence of hydrocarbons was verified and the taxonomic and functional aspects of the lake microbiome were assessed. The analysis revealed specialized successional patterns of lake microbial communities that were potentially capable of degrading complex, recalcitrant hydrocarbons, including aromatic, chloroaromatic, nitroaromatic, and sulfur containing aromatic hydrocarbons. Our findings indicated that changes in the freshwater microbial community were associated with the oil pollution event, where microbial patterns identified in the lacustrine microbiome 3 months after the oil spill were representative of its hydrocarbonoclastic potential and may serve as effective proxies for lacustrine oil pollution.
