With a total length of 39 meters and width of 10.5 meters, Yungang Electric Tug No. 2 has a maximum navigational speed of 13 knots and a bollard towing force of more than 65 metric tons.
The tugboat can be fully charged within two hours of fast charging and the battery capacity is enough for a whole-day's operation.
The tugboat is equipped with high-performance direct current (DC) power distribution electric propulsion system and core devices with independent intellectual property rights such as a high-security lithium battery system, a two-megawatt highly-efficient vertical hollow shaft permanent magnet motor, a new-generation high-performance DC power distribution center, and an automation system as well as remote operation and maintenance systems.
The total capacity of the tugboat's lithium battery is nearly 8,000 kilowatt-hours, exceeding the total capacity of 200 electric vehicles. Compared with conventional tugboats, Yungang Electric Tug No. 2 consumes about 400 tons less fuel.
What's more, the tugboat has an outstanding performance in pollutant and noise emission as well as energy consumption.
It is estimated that the tugboat can reduce emissions of about 900 tons of carbon oxides and 12 tons of sulfur oxide annually, with huge environmental benefits, high safety coefficients, zero operational risks and low operating costs.
It will be used to assist berthing and departing of large ships in the Lianyungang waters and is expected to support construction of the smart and green port.
