Worlds first hybrid tug

The port of Long Beach in California is sponsoring a new hybrid engine tug project to reduce emissions. “This is exactly the kind of innovation we are looking to help fund with our technology programme,” said Harbour Commission President James C. Hankla. The port will contribute $500,000 to the $8 million project, with the tug to be built by Seattle-based Foss Maritime.

The vessel’s hybrid engine will use diesel power for normal operations but switch to an electric engine during idling, much like a hybrid car, and will be “the first of its kind in the world”, according to the port authority. Emissions from the hybrid engine will be reduced by at least 44% and fuel economy improved by 30%.

The tug will cost around $3 million more than a conventional configuration and the Port of Los Angeles may also contribute to the project. Construction is expected to begin this year and the new tug to enter into operations in 2008.
