Simulation study on prevention and control of oil spill pollution in the approach channel of Bohai Bay Port

Abstract

Based on the results of tidal current calculation and wind field data analysis, this study uses an oil spill model to predict and analyze the oil film. This model simulates a series of physical and chemical processes such as oil spill drift, diffusion, weathering, and shoreline adsorption, and predicts the trajectory and destination of oil film drift. The oil spill model determines the water and land boundary and the simulation prediction parameter range according to the land and water grid. After inputting the wind and flow fields such as weather and sea conditions data and oil spill accident site data, the oil spill accident is analyzed by a series of mathematical models such as the tidal current model and the destination model. It is needed to carry out simulation prediction, predict its drift trajectory, etc. The calculation results show that when an oil spill occurs at the gate of Nangang Port, the oil film will float out of the Nangang Port, which will have a certain impact on the surrounding environment within a certain range under the action of wind.
