Abstract: JZ 9-3 CEPD is an 8-leg center platform with a distinctive split-type jacket. According to the topside float-over installation requirements to depth and width of the jacket slot, the jacket of JZ 9-3 CEPD platform is divided into two independent structures. The accuracy control of pile decides whether the jacket installation an is successful or not. Based on actual project, the process is analyzed for the comparison and optimization of the ultra-shallow water split-type jacket installation plan are analyzed. It could be good references to the exploitation of offshore oil in future.
