A risk assessment method for marine oil spill

Abstract

The invention belongs to the field of marine pollution risk assessment and monitoring, and particularly relates to a marine oil spill risk assessment method. The marine oil spill risk assessment method comprises the following steps of (1) risk source assessment; (2) risk diffusion calculation; (3) sensitivity analysis; and (4) oil spill risk division. The concrete operation of the step (2) is that a climate state marine oil spill risk diffusion model is established based on the marine environment, the hydrodynamic characteristics and the wind field variations of different seasons of the research marine area by using an oil particle drift diffusion simulation method, each oil spill risk source risk diffusion field is monthly calculated and the level of the oil spill risk is determined through superposition calculation. The climate state marine oil spill risk diffusion model is established so that the requirement of high-resolution calculation of the oil spill risk diffusion precision can be met, the calculation burden can also be saved and integrated oil spill risk calculation of the marine area level is enabled to be feasible.

Description

technical field [0001] The invention belongs to the field of marine pollution risk assessment and monitoring, and in particular relates to a marine oil spill risk assessment method. Background technique [0002] With the continuous and rapid development of the global economy, the demand for energy continues to increase, offshore oil exploration and development and offshore oil transportation have increased rapidly, and marine oil spill accidents have also continued to increase. The risks of coastal and inland rivers, water, underwater and land oil spills Significantly increased, a serious threat to the marine and coastal ecological environment. Oil spills mostly occur at sea. As the wind and waves drift to the coastline, oil spills not only cause serious environmental pollution to the sea surface, but also cause environmental quality and biological diversity in coastal waters due to the potential toxicity and bioaccumulation effects of petroleum hydrocarbon pollutants. The ...

Problems solved by technology

In general, compared with foreign countries, my country's oil spill risk assessment started relatively late, and the work in this field is still in its infancy, and there is still a lack of systematic methods and research

In particular, there is a lack of sea area-level, comprehensive, and systematic oil spill risk assessment methods, and the key technologies of the assessment methods need to be broken through
