Offshore oil spill quick prediction system based on tide periodicity and self-similarity

Abstract

The invention discloses a quick offshore oil spill prediction system based on tide periodicity and self-similarity. The quick offshore oil spill prediction system comprises an oil product leakage information feedback platform, a tide real-time observation platform, a real-time tide level database, a historical tide level database, a flow field information search module, a flow field information database and an oil spill diffusion simulation module. Various possible flow fields are calculated in advance according to local historical tide level data and are stored in a flow field information database; after an oil product leakage accident occurs; the current real-time tide level data can be used; quickly searching the calculated flow field closest to the current flow field by means of a flowfield information search algorithm; flow field data is directly read; according to the method, the ocean current field simulation part which consumes the most time in oil spill diffusion simulation can be skipped, the oil spill diffusion area is directly calculated, the time required by oil spill diffusion simulation can be shortened to several hours from several days, precious time is bought forcoping with oil product leakage accidents, and serious economic losses and ecological environment damage are avoided.

Description

technical field [0001] The invention relates to the field of prevention and control of marine disasters, in particular to a set of systems and technical methods for quickly predicting the spread of oil spills at sea. Background technique [0002] In recent years, with the improvement of my country's industrialization level, my country's demand for marine crude oil exploitation and transportation has also increased. At the same time, the risk of my country's offshore oil product leakage has also increased. For example, the CNOOC Bohai Bay oil spill accident in 2011 not only caused great economic losses to my country's oil companies, but also caused a huge threat and damage to the ecological environment of Bohai Bay. Therefore, it is very important for the pre-disaster prevention of oil spill accidents and the timely prediction of oil spill diffusion areas after disasters. [0003] Among them, the main method to predict the oil spill spread area is to establish an oil spill ...
