On behalf of Stena Line, Stena RoRo has designed and ordered two hybrid cargo ships from the Chinese shipyard CMI Jinling in Weihai. The ships can be powered by methanol or conventional fuel and have been developed in line with future environmental requirements, for example by using batteries as a future means of propulsion. Major emphasis has been placed on optimizing the cargo capacity, which has been increased by 80%.The 147-meter-long vessels have been specially designed for Stena Line's route between Belfast and Heysham on the Irish Sea and therefore have enhanced maneuverability.
