Abstract

The paper analyzes the mechanism of the spilled oil being chemically dispersed and the main factors that determine the effectiveness of the dispersant, and introduces the method of spraying dispersant in deepwater environment used in the “Deepwater Horizon” oil spill accident. Numerical methods are developed to track the oil spill trajectory after applying dispersants in deepwater by improving a three-dimensional deepwater oil spill model (DOSM). The improved model is used to predict the oil spill trajectory with and without spraying dispersants to the spill source in deepwater environment. Simulation results show that the chemical dispersed oil droplets of diameter less than 0.5 mm be diffused in the underwater environment and move to the sea surface slowly, of which the oil droplets of diameter less than 0.1 mm tend to form a suspended oil plume in deepwater.

Key words： deepwater oil spill; chemical dispersant; transport and diffusion; numerical modeling; trajectory prediction
