Abstract:This article has a successfully put into operation example of a separated lifting topsides of eight legs central production platform in Bohai sea。According to the idea of integrated design, in the detailed design phase through the marine lifting optimization of separated lifting topsides of eight legs central production platform, it not only reduces the occupation of key production resources such as large floating cranes and the input of labor costs, but also by shortening the offshore construction time to reduce the uncertainty risk of offshore construction. In addition, the redundancy of the structure can be effectively used to achieve the optimization of the structure and achieve the purpose of reducing cost and increasing efficiency. Through the analysis and demonstration of professional computing technology, this article proves the feasibility of this optimization scheme
