Abstract: In recent years,the huge energy demand prompted a blowout development of marine oil transport and oil production activities in China,but also significantly increased the risk of oil spill accidents.A serious oil spill may bring irreversible harm to the marine environment,and will cause an immeasurable loss of economy.Therefore,it is necessary that the study on numerical prediction technology of marine oil spill behavior and fate and can provide technical support for oil spill response.This paper briefly introduced the development and achievements of the numerical prediction technology of oil spill behavior and fate,including the oil spill spreading model,the oil spill drift and diffusion model,the weathering model and the oil spill prediction model system,which provide the theoretic criterions for the future work on oil spill response.
