Parametric Sensitivity Studies for Floatover Installation Analyses of Liwan 3-1 Mega Topsides with a T-Shaped Launch Barge

摘要

This paper details the rational floatover analysis method and itsrnapplication in the successful floatover installation of the LW3-1rnCPP Topsides. The main purpose of the floatover analyses is torndetermine the design loads and operability for each stage duringrndocking, mating, and undocking operations. The findings of thernparametric sensitivity studies ensure the integrity of the megarntopsides and the preinstalled jacket, as well as the T-shapedrnbarge, and therefore enable the challenging floatover installationrnas rapidly as possible coincident with safe practice in the deeprnwater and harsh environment of South China Sea.
