Assessing oil spill risk in the Chinese Bohai Sea: A case study for both ship and platform related oil spills

Abstract 2017-184: Accidental release of pollutants such as offshore oil spills can cause significant negative impacts on the environment and socio-economy, and constitutes a direct hazard to marine life and human health. Particularly, deepwater blowout released spills are more challenging to study because the trajectory and behaviour of oil are difficult to be comprehensively simulated. Although there are many integrated or coupled models available, there still lacks open source deepwater oil spill models to predict not only the trajectory but also the mass balance of oil. It is the objective of this study to fill this gap by coupling the Texas A&M Oilspill Calculator (TAMOC) for nearfield simulation and the advanced oil spill module in the Modelo Hidrodinâmico (MOHID) 3D Water modeling system. In addition, the Weber number scaling approach is also integrated in both the near- and far-field simulation for oil droplet size prediction. The applicability of the proposed comprehensive system is tested by a case study of simulation of oil spills released from a depth of 3,500 m in the Scotian Shelf, Canada. The results demonstrate a high feasibility of the proposed system. By providing comprehensive simulation for oil spills, the developed system should provide significant support to the response to offshore oil spill, especially from deepwater blowout.

An oil pipeline ruptured in May 1994 and 2 700 tons of crude oil leaked into the São Sebastião Channel, affecting several neighboring areas. A program for the monitoring of hydrocarbons in sediments, using the gas chromatography / flame ionization detector methodology, was being undertaken in the area at the time. The data obtained were compared to those of samples collected after the accident to determine the fate of the oil spilled and ascertain its contribution to the environment. The earlier results showed that hydrocarbons were introduced from two different sources: biogenic, mainly from terrestrial plants, and anthropogenic, as oil, in sewage and from shipping. The later data indicated that the site closest to the pipeline rupture had been the most affected. Following that, two stations located at the north entrance of the channel presented the highest n-alkane concentrations, suggesting that the northeasterly wind-driven currents had carried the oil northward. Seven months later, one of these stations, a high-energy site, showed some signs of recovery, but this process was not observed at the other, which seemed to be a low-energy site. In conclusion, the data showed that the aliphatic hydrocarbon analyses were powerful tools for the assessment of the fate of the oil spill and that the northern part of the São Sebastião Channel is more subject to the effects of oil spills.

Oil Particles

A three–dimensional integrated model is developed for simulating oil spills transport and fate in seas. The model contains two main modules, flow and transport-fate module. The transport module uses an unstructured finite volume wave-current coupling model, giving a more accurate result compared to structured model, especially for a region has a complex coastline. In the transport-fate module the oil dispersion is solved using a particle-tracking method. Horizontal diffusion is simulated using a random walk techniques in a Monte Carlo framework while vertical diffusion process is solved based on the Langeven equation. The model simulates the most significant processes which affect the motion of oil particles, such as: advection, surface spreading, evaporation, dissolution, emulsification, and turbulent diffusion, the interaction of the oil particles with the shoreline, sedimentation and the temporal variations of oil viscosity, density, and surface-tension. This model has been applied to simulate the oil spill accident at the strait of Bohai Sea. In comparison with the observations, the numerical results indicate that the model is reasonably accurate.

ABSTRACT The Hazardous Material Response and Assessment Division (HAZMAT) at the National Oceanic and Atmospheric Administration uses the oil weathering software package named Automated Data Inquiry for Oil Spills (ADIOS) to investigate the oil weathering process. This model combines a database of physical and chemical properties of oils with a simulation model computing mass losses, density, viscosity, and water content of an oil spill due to evaporation, dispersion, and emulsification. A first-order sensitivity analysis of the ADIOS evaporation algorithm indicates that it might be possible to provide a taxonomy of oils with respect to the reliability of results generated by the model.

ABSTRACT Governments and industry, both national and international, contend that dispersants are an effective and practical response option under certain circumstances. However, a comprehensive training and education program in dispersant operations used to establish a baseline of understanding among responders and stakeholders is lacking. Dispersant operations have played a positive and significant role on numerous oil spills in both national and international waters, yet a curriculum in dispersant operations remains a minor component of oil spill response course curricula. This may suggest that decision makers, responders and ultimately the public and environment are being shortchanged of alternative response technology training and education, which essentially fails to meet the needs of regional response teams, area committees, natural resource trustees, and the general oil spill response community's future decision makers. Supported through case study analyses and critical argumentation, this paper presents an oil spill dispersant operations curriculum that governments and industry, both national and international, can adapt.

Oil spills near the shore is an important environmental problem. The oil spill has to be contained in the early stages of the accident which otherwise would spread rapidly making it hard to control. The oil gets weathered affecting marine life and can get into the food chain and cause ecological distress. It also affects port and harbour activities. The after effects of the spill are mostly irreversible, so it is essential to follow proper control measures. It is essential to establish the spill forecast and movement for necessary prevention and mitigation measures. To do this, oil spill trajectory forecast models need to develop, that helps to provide the action plans to control the spill. A hydrodynamic simulation is carried out for the Ennore 2017 Chennai oil spill of India and corresponding trajectory analysis is performed. The results of the simulation will aid for effective cleanup measures to be followed in the region.

Fish And Shellfish

ABSTRACT Following the 2007 M/V Cosco Busan oil spill in San Francisco Bay, California, legislation was enacted to provide for the closure of fisheries by the California Department of Fish and Game (DFG) after oil spills in marine waters. This legislation (DFG Code Section 5654) facilitated a partnership between the state's primary oil spill responder, the Department of Fish and Game, Office of Spill Prevention and Response (DFG/OSPR), and the state's Office of Environmental Health Hazard Assessment (OEHHA), the agency responsible for determining whether fish caught in California waters can be safely consumed. A fisheries closure protocol established as a result of the statute stipulates the role of staff at both agencies, from the initial spill responders to data evaluation and reopening of a closed fishery. OEHHA staff is required to assess the need for fisheries closure following a spill event. When a fisheries closure is deemed necessary for more than 48 hours, OEHHA will select species and chemicals for analysis, determine sampling strategies, conduct a risk assessment on the safety of fish and shellfish consumption, and work with DFG/OSPR to modify closure boundaries, if indicated. Relevant case study information from California spills, including the T/V Dubai Star is shown.
