Float-Over Installation Analysis of Semisubmersible Production Platform Topside
View through CrossRef
Compared with split lifting by floating crane, the float-over is less time-consuming and has larger lifting capacity, especially suitable for large and medium sized offshore platforms. Float-over installation process of a deepwater semisubmersible platform topside is analyzed in this paper. And the multi-floating coupling calculation is carried out in the typical loading conditions of mating process between topside and column top structure. The motion response of leg mating unit in position of barge is received. The calculation results show that the float movement condition meets float-over installation requirements of topside. The analysis can provide a reference for the project of the float-over installation in the future.
