JAPAN'S FIRST HYBRID TUG ENTERS INTO SERVICE

摘要

Japan's first hybrid tug, the Tsubasa, has entered into service for the NYK Group. Developed and manufactured with support from ClassNK, the tug is equipped with a motor generator, high-performance batteries and conventional diesel engines. Depending on what power is needed, the tug can operate solely on its diesel engines or electric-motors, making it fuel efficient and lowering CO_2 emission. CO_2 emissions are expected to drop by 20% in port. The tug is performing ship assist towing operations at the Port of Yokohama and Kawasaki.
