NYK Celebrates Japan's 1st Environmentally-Friendly Tugboat in Yokohama
March 28, 2013
Yesterday, Wing Maritime Service Corporation held a ceremony in Yokohama Port to mark the entry into service of the NYK Group’s tugboat "Tsubasa"(Gross Tonnage: 256 tons) featuring a hybrid propulsion system. A preview of the “Tsubasa” was also held on the same day and was attended by Yokohama deputy mayor Nobuya Suzuki and a number of other guests. At the ceremony after the preview, the vessel was presented with a video provided by the tugboat builder Keihin Dock Co. Ltd. and Niigata Power Systems Co.,Ltd.
Since March 15, "Tsubasa" has been used in towing operations which help large vessels get into and out of ports, mainly at the port of Yokohama and Kawasaki. She is equipped with a motor generator and high-performance rechargeable batteries in addition to conventional diesel engines. Capable of operating solely on her diesel engines and/or on her electric-motors depending upon the operating power needed, a fuel-efficient and low CO2 emission performance is achieved. In addition, the batteries can be charged not only by the onboard power generator, but also via electric-power from land. With these environmentally-friendly features, the new tugboat is expected to emit 20 per cent fewer CO2 emissions in port.

(head office: Chiyoda-ku, Tokyo ; president Junichi Saikawa). Niigata Power Systems developed and manufactures the hybrid propulsion system.
