"The operation page shows normal. The sockets of the shore power piles have good contact, no water accumulation and the lines have no abrasion, so they can be used normally!" Staff member He Jianjie said as he conducted a comprehensive "physical examination" on the shore power pile facilities. He checked the pile body, the insulating layer of the charging cable and other parts, and used an infrared thermometer to detect key parts such as the gun head, gun body, cable and grounding of each charging pile, so as to discover and dynamically eliminate potential faults of offline shore power facilities in a timely manner and ensure that the availability of the facilities reaches 100 percent. According to estimates, after berthed ships use high-voltage shore power, on average, each berth can save 1.2 tons of fuel oil per year and reduce the emissions of various air pollutants by about 0.5 tons.
