Marine Oil Spill Hazard Risk Assessment And Its Preventive Measure

With the booming development of the offshore and gas exploration, offshore operations become into the deepwater and ultra-deepwater era, engineering equipment to large-scale, intensive, complicated, automation and the development of the subsea production system, and the resulting oil spill risk grow with each passing day, oil spill accidents in an endless stream. Therefore employing appropriate method to assess the risk of offshores’ oil spill, then finding key risk factors and forecasting the harm degree correctly, makes great sense not only for the risk Prevention but also for the emergency treatment.This paper first reviews the major oil spill at home and abroad in recent years offshore oil platform, and combined with national experts in the offshore oil spill risk assessment field research, by comparing the technique characteristics of various risk assessment method, the author select Fuzzy Comprehensive Evaluation(FCE) and analyzes five factors may result in offshore oil platform of oil spill accident harm degree (hydrological factors, meteorological factors, oil properties, oil spill position. oil spill clean-up situation), Then established the evaluation index system.Then analytical hierarchy process(AHP) was used to calculate the weights of evaluation indexes and the membership function and the membership degree, establishing an offshore oil platform of oil spill accident harm degree FCE model, using FCE method for the assessment of calculation, and combined with the offshore oil platform. oil spill accident hazard degree influence factors of serious analysis and research, proposed the corresponding prevention measures.
