The estimation of regional oil recovery capacity based on marine oil spill response scenario in Vietnam

ABSTRACT The oil spill recovery capacity-OSRC plays a vital role in setting up national or regional response capability to combat the big risk of marine oil spills from oil transportation activities around Vietnam. However, in preparedness for marine oil spills, it is not known how much the amount of OSRC Vietnam should have. In this study, the criteria of marine developed countries for the establishment of marine OSRC are reviewed, and Vietnamese current conditions based on oil transportation and offshore activities are examined. In addition, Vietnamese marine oil spill recovery scenario is created, and therefrom Vietnamese regional oil spill recovery demand-OSRD and regional OSRC are estimated quantitatively through the calculations with the main factors such as the maximum amount of oil spill, the percentage of oil quantity remaining on water, emulsification factor, mobilization factor, total nominal throughput rate of all oil recovery devices. This contribution is necessary to improve and reinforce the areal, regional, and national OSRCs or aOSRCs in conformity with the corresponding areal, regional, and national OSRDs or aOSRDs in Vietnam and to balance properly the allocations of OSRCs or aOSRCs by area, by region, and nationwide in Vietnam, on the basis of the scientific and quantitative estimation results.
