Optimization Analysis on Steel Module Lifting System

The tower of the lifting system is the key equipment which ensures the modules being lifted and installed on the deep sea oil extraction platform. As the important bearing structure in the lifting system, the tower has complex force conditions and its quality has great influence on the working performance of the whole lifting system. In terms of the designed gantry tower structure, this paper will use the length and wall thickness of the steel pipe of the gantry tower system as the design variables, the minimum total weight of the tower system as the objective function, the strength and stiffness of the tower system as the constraints. The gantry tower structure is the direct load-bearing structure of the lifting system. Conducting optimization analysis on the gantry tower structure will significantly reduce its weight, make its structure simpler and more reasonable, thus increasing its dependability.
