For the first time in the country!Shandong Port Qingdao Port realizes 400,000 tons of large ship cleaning shore electric energy applications

Qingdao Daily/Guanhai News, September 6th. Recently, the world's largest 400,000 -ton large ship "Ming Qing" wheel of 400,000 tons of large ships in Qingdao Port Mining Company, Shandong Port, successfully connected to the pier shore and realized the grid grid grid grid. Operation marks the first time that Dong Mining Company has achieved clean shore electricity in the country in the country in 400,000 tons of ore vessels.

For a long time, high -voltage shore electrical equipment and shipping equipment come from different manufacturers. The voltage fluctuation processing techniques are different. The excitement flow generated by the gates cause voltage fluctuations, which can easily cause equipment failures and cause hidden safety hazards. When the ship is connected to the shore electricity for the first time, the technician needs to log in to the wheel on the spot. Due to the prevention and control of the new crown epidemic, the outer ship ships are not allowed to enter the cabin debugging, resulting in the 400,000 -ton large ships without the application of the dock shore power worldwide.

In response to this situation, Dong Mining Company organized technical personnel, and the opposite shore power system was fully upgraded and transformed, and the anti -wave rushing device and load control system were developed. Technically ensured the successful connection of the joint ship.

In order to solve the problem that the electrical engineer cannot board the ship, the maritime department of Dongjiakou provides a remote communication system for equipment debugging, and uses advanced technologies such as 5G and AR to solve the problem of limited contact with the technical personnel on the shore. The joint ship has successfully provided service guarantee. Under the cooperation of various departments, Dong Mining Company finally achieved the nationwide of the world's largest 400,000 tons of ships in the world for the first time.

The 400,000 -ton -class large ship realizes the shipping of the ship's shore. It provides rich operating experience and technical support for the research of the brothers port to carry out the research of ship coast electricity. It will also greatly increase the coastal power access rate of the nationwide coastal ports, effectively reduce the environment for the environment Pollution.

According to statistics, a 400,000 -ton cargo ship is used in Hong Kong to use shore electricity, which can reduce fuel consumption by about 12 tons, reduce carbon dioxide emissions by about 37.4 tons, and reduce sulfur oxide emissions by about 0.1 tons. All 400,000 tons of large ships are all connected to shore electricity. The nation's coastal ports will reduce carbon dioxide emissions by about 5,500 tons each year, and about 15 tons of sulfur oxide emissions. Zero pollution and zero noise ", promoting the construction of a low -carbon transportation system, and helping to achieve the goal of" carbon peak, carbon neutrality ", is of great significance.
