Description

technical field

[0001] The invention relates to a risk assessment method, in particular to a risk assessment method for a self-elevating ocean platform. Background technique

[0002] As a very important tool in offshore operations, jack-up drilling platforms have been used more and more in recent years. Reducing the risk of platform use and avoiding safety accidents is an important aspect to ensure the stable and reliable use of the drilling platform. However, so far, the development of risk assessment methods for jack-up offshore platforms in my country has been relatively slow. Although there has been some technical research, a complete system has not yet been formed. Therefore, the current domestic risk assessment of jack-up offshore platforms There is still a gap in the evaluation method, so the operation safety and reliability of the self-elevating offshore platform cannot be well guaranteed from this aspect.
