Abstract: Crane is one of the important equipment for cargo hoisting and personnel getting up and down in offshore operation facilities. Generally,the crane adopts diesel engine or motor as the power drive system. The crane with dieselengine as the power system not only consumes diesel during operation,but also needs regular shutdown for maintenance. However,cargo hoisting and personnel getting up and down in offshore operation facilities are relatively frequent,and the crane does not have the conditions for long-term shutdown. In order to ensure the normal use of the diesel engine driven crane during shutdown maintenance or failure,the single drive system of the diesel crane is upgraded to a diesel electric dual drive system,and the control operating system and safety protection device are upgraded,so as to achieve the maintenance of the diesel engine when the crane is not out of service and the continuous and reliable operation of the crane.

Key words: power system, diesel electric dual drive, energy conservation and emission reduction
