Abstract: In this paper, a new construction technology of transportation and installation for jacket foundation by semi-submersible barge in vertical transportation is proposed, which provides upward buoyancy for jacket foundation through the diving process of the semi-submersible barge, thus reducing the lifting force of crane, and solving the applicability problem of field crane. Based on this new construction technology, the hydrodynamic model of jacket foundation for semi-submersible barge transportation and installation is established by using 3D potential flow theory. Through numerical simulation, the influence of diving depth, significant wave on the movement and force of jacket foundation & semi-submersible barge system is studied. In order to demonstrate the feasibility of transportation and installation of jacket foundation in semi-submersible barge, the risk analysis of diving operation of semi-submersible barge is carried out. The allowable roll angle of diving operation for the jacket foundation of semi-submersible barge transportation and installation is put forward, which limits the safe working conditions of semi-submersible barge and provides scientific basis and technical support for the new construction technology of jacket foundation transportation and installation.
