The law of diffusion and migration of oil spill from submarine pipelines under wave action

In order to minimize the environmental pollution and economic losses caused by the oil spill accidents, the influencing factors of the oil spill diffusion behavior of submarine pipelines were studied. Firstly, a two-dimensional model with wind under wave conditions was established by using hydrodynamics software, and then verified. Secondly, the oil spill simulation was carried out by the model, and the effects of crude oil density, wave length, and wind speed on oil spill diffusion were analyzed and discussed. The research results show that: 1) the simulation results of the established two-dimensional model with wind are more consistent with the experimental values and more reliable than the literature model, which can be used to predict submarine oil spills; 2) the crude oil density significantly affects the time to sea level and the lateral drift distance of oil spill; 3) the wave length has a slight effect on the ascent speed of oil spill, but significantly affects the lateral spread; 4) the wind speed has little effect on the process before the oil spill reaches sea level but accelerates the spreading process after arrival. The research results can provide a scientific basis for the formulation of emergency treatment plans and the recovery and utilization of oil spill.
