Sustainable propulsion concept for Scottish ferries

摘要

The Scottish Company Caledonian Maritime Assets Limited (CMAL) has selected Imtech Marine to build an ef-ficient propulsion System for two seagoing hybrid ferries. Since the new ferries are meant to emit less CO_2 by using less fuel, alternative energy sources were considered. The ferries, to be operated by Clyde and Hebrides Ferry Services' CalMac Ferries, will be designed for the numerous short routes around the Clyde and Hebridean islands. With a service speed of 9 knots, they will be able to accommodate 150 passengers and 23 cars or two heavy goods vehicles. CMAL's ambitious ideas inspired Imtech to create a new energy management System that controls the power sources in the most efficient way, together with a user-friendly human interface.
