Abstract：In order to solve the problems of high energy consumption and high emissions of offshore platform cranes and improve energy efficiency,considering the cost of power batteries and the irreplaceable typical advantages of diesel engines in safety and reliability,a hybrid power scheme for offshore platform cranes is proposed,which monitored the state of charge(SOC)of batteries and the dynamic load of the crane,the collaborative control strategy is designed,and the simulation verification under the typical working conditions of the crane is carried out.The results show that the fuel consumption and CO2 emission of the heavy duty diesel engine driven by the diesel engine-lithium battery hybrid system are significantly reduced.After 8 h typical operation cycle,the fuel consumption of the traditional diesel engine crane and the hybrid crane are 141.0 kg and 120.2 kg,with the CO2 emissions are 435.7 kg and 371.3 kg,respectively,both the fuel consumption and CO2 emissions are reduced by 14.8％.
