【 摘 要 】

The paper takes the real jacket offshore platform as an example. The structural finite element software structural analysis was used to establish the structural section optimization, shape optimization and shape optimization model based on component reliability. The results reflect that the shape optimization efficiency based on component reliability is high under the premise of guaranteeing the reliability of the structure. Therefore, preference should be given to the structural shape optimization considering reliability in the engineering.
