Problems solved by technology

However, the existing oil particle method uses empirical values ​​to estimate the thickness of the oil spill, which has a large deviation from the actual thickness of the oil spill. Using the empirical value of the thickness as the initial value for the iterative calculation of the offshore oil spill trajectory simulation will cause the simulation accuracy to decrease. , and the prediction time of the oil spill trajectory that meets the accuracy requirements is shortened

Abstract

The invention discloses a sea oil spill track simulation method based on thickness information. Firstly, the calculation initial value of the oil spill volume is obtained by using the remote sensing image and the sea oil spill thickness, and then the oil spill volume is updated by using the weathering model, and then the oil spill volume is used to The volume of the oil particles is updated with the update formula, and then the coordinate information of the oil particles is updated by using the hydrodynamic model to obtain the oil spill trajectory. Finally, the oil spill concentration and oil spill volume are calculated by using the discretized numerical calculation method. The invention has no special requirements on the oil film thickness acquisition device and method, has a wide application range, and considers the realizable problem of computer calculation, and has strong practical value and broad market prospect.

Description

technical field [0001] The present invention relates to the simulation of oil spill drift trajectory after marine oil spill accidents, in particular to a method for simulating oil spill trajectory by comprehensively utilizing oil film thickness information acquired by an offshore oil film thickness measuring device and an oil particle method. Background technique [0002] The marine oil spill accident is the most serious marine ecological pollution and ecological disaster, which causes huge economic losses and pollution consequences. Timely and efficient emergency response to oil spill pollution accidents is an effective means to reduce the impact of oil spill disasters. The oil spill trajectory simulation aims to simulate the irregular shape of the oil film, the drift trajectory, and the amount of oil spilled. It plays an indispensable and important role in the decision-making and implementation of the emergency response plan for oil spill accidents. [0003] At present, t...
