Abstract:

As offshore wind power gradually moves towards the deep sea, the size and weight of offshore booster station jackets are also getting larger. The number of cable protectors of the offshore booster station jackets is large, making installation difficult. If use the installation method of traditional oil and gas jacket’s J-tube, the project duration and cranes will be greatly affected. This paper discusses an integration lifting technology of J-tube and structural piece,which lifts the J-tube and structure in place at the same time, and checks the structural strength and local strength of lifting points under different working conditions. Provide technical basis for construction of wind power technology to break through in deep sea areas.

Key words: Offshore booster station jacket, J-tube, integrated lifting, SACS, ANSYS
