Taking the twin-hull development platform as the research object, this paper proposes the structural modification plan and performs the motion and structural performance research, and introduces the connecting bridge structure design idea for the modification of twin-hull platform. Based on 3D potential flow theory, the SESAM software is adopted to perform numerical analysis on the platform motion and load responses; the spectral analysis method combined with the wave statistical data is used to perform the long-term motion and load response prediction; based on the extreme working condition requirements on the equipment, short-term predictions are performed according to the operating windows of each season; the allowable operating environment range of the equipment is studied, so as to evaluate the feasibility and economical efficiency of the design. Based on the spectral analysis design wave method, the design load of the platform is determined, and the wave load direct strength analysis and verification is performed using finite element method. In order to reinforce the structural strength of key regions such as the connecting-bridge structure, a structural modification plan for the twin-hull platform is proposed, providing an analytical basis for the further design of the platform.
