Study on quantitative risk assessment and inspection of offshore pressure vessels

Quantitative risk assessment of pressure vessels for offshore oil and gas production is beneficial for controlling risks,optimizing design,reducing production costs,guiding the implementation of risk mitigation measures and formulating inspection cycles and inspection plans.A quantitative analysis method is used to calculate the damage coefficient,probabilities and consequences of failure of the pressure vessel.The risk grade of the pressure vessel is divided in accordance with the established risk acceptance criteria,and the future inspection cycle and inspection plan are guided.The research results can accurately and quantitatively evaluate the risks of pressure vessels,and formulate inspection cycles and inspection plans for the risks.This method has been successfully applied to offshore and FPSO in China's seas and can be used as a reference for other projects.
