To deeply implement the national “dual carbon” policy,promote the improvement of shore power utilization rate during ship berthing,and further reduce air pollutant emissions during ship berthing,this paper introduces the background and significance of shore power construction in ships and ports,analyzes the current development status and trends of shore power technology at home and abroad,and briefly describes the shore power construction situation of major domestic ports and shipping enterprises.Based on the current situation of shore power usage in key domestic ports and shipping enterprises,this paper analyzes the main influencing factors that restrict the improvement of shore power usage rate.Focusing on the lack of unified hardware standards for shore power equipment and facilities,isolated islands in information system construction,and temporary equipment failures,the paper proposes multiple suggestions and countermeasures,including unifying equipment standards,strengthening organizational scheduling,promoting intelligent construction,balancing charging policies,and policy guidance.The government needs to strengthen policy planning and services,port and shipping enterprises need to actively play a leading role,and industry departments need to extensively collaborate and participate to form a working force,jointly promote the improvement of the utilization rate of shore power at ship terminals,and contribute to high-quality development.
