The vessels will hit the waters from October 2013, operating along the west coast of Norway.
The award-winning Environship concept offers ships a wave piercing bow design powered by gas engine and the Promas propulsion system that improves fuel efficiency, according to Rolls-Royce.
The environmental benefits include the virtual elimination of SOx and a reduction of CO2 emissions of more than 40% compared to similar vessels.
“The Environship is a real game changer for the merchant shipping market, offering significant reductions in fuel burn and emissions as well as enhanced performance at sea,” said Oddbjørn Eliassen, president – merchant, at Rolls-Royce.
The contract includes an option to build an additional two vessels of the same design. Rolls-Royce has already developed the Environship concept to a wide range of ship types including passenger ferries, chemical tankers, gas tankers, bulk carriers and superyachts.
