Crude oil leakage from a tanker is usually a serious disaster to the ocean. Predicting the behaviors of leaked oil is of great significance to the quick response and decision for the early stage of such disasters. The simulations of such flows are usually difficult by the conventional grid methods because there are three types of interfaces (water-air, water-oil, oil-air) required to be tracked. In this paper, the spreading of the spilled oil are investigated by a multiphase particle method, which is developed based on the Moving Particle Semi-implicit method (MPS). The multiphase MPS method and simulated results are briefly presented in this paper.
