Abstract

The invention provides a comprehensive safety assessment method for an ocean platform, which comprises ocean platform safety risk identification, ocean platform safety risk assessment and ocean platform safety risk control, and can reduce the risk of the platform during working and avoid the occurrence of safety accidents. According to the invention, a risk evaluation matrix comprising multiple risk factors is established, and comprehensive assessment of various risks of the ocean platform is realized. The risk factor is simplified through target decomposition; A comprehensive assessment modelinfluencing platform safety is built, a risk assessment matrix is built, the relative weight of each level is calculated, weighted synthesis is carried out to obtain a combined weight, risk responsemeasures are formulated, the comprehensive safety risk assessment capability of the ocean platform is improved, and therefore risks are effectively reduced in time, and safety accidents are avoided.

Description

technical field [0001] The invention belongs to the technical field of ocean engineering, and in particular relates to a safety assessment method, in particular to a comprehensive safety assessment method for ocean platforms. Background technique [0002] With the continuous discovery of my country's offshore oil and gas fields and the country's demand for offshore oil resources, the scale of offshore oil exploration and development is increasing. As an important tool in offshore operations, offshore platforms have been used more and more in recent years. The production and operation of offshore platforms in the marine environment needs to face very harsh natural environments. Increase its safety hazards; the collision of other ships or the platform’s grounding or grounding will change the structure of the platform; on the other hand, the long-term use of the platform and the corrosion of seawater will have a certain impact on the structural strength and fatigue life of the ...
