Abstract: The maintenance process of the marine large equipment is very complex. The equipment extraction scheme is usually designed relying on the personal experience, resulting in the problems in the practical production, such as the insufficient space for the equipment extraction, missing operation and redundant operation. A simulation based method is proposed for the design and optimization of the equipment extraction scheme aiming at these issues. The extraction process of the generator rotor of a ship has been examined to analyze the specific procedure and the key points of the simulation of the extraction process for the marine large equipment, achieving the visual analysis and optimization for the simulation of the extraction route. The results show that the feasibility and rationality of the extraction scheme can be proved by using this method, and the potential problems of the equipment extraction scheme can be exposed in advance. The extraction scheme can be improved through the process of “analysis, simulation and optimization”, in order to further shorten the design time and improve the maintenance efficiency.
