The Study of Risk Assessment on the Ship Oil Spill Diffuseness

Ship oil spill is one of the most serious marine pollutions. By assessing the risk of oil spill’s diffuseness, revealing the complex rules of its occurrence and taking appropriate preventive and emergency measures, we can minimize the pollution. With Yangshan’s waters in Shanghai as the background, this paper, using hierarchic analysis, gives a model of risk assessment on the oil spill’s diffuseness in Yangshan and a risk assessment on the oil spill’s diffuseness on the real ship, providing a scientific basis to effectively avoid pollution caused by oil spill diffuseness.
