In September 2016 MTU had presented its mobile MTU gas engines for marine propulsion applications for the first time at the SMM International Maritime Trade Fair. The engines meanwhile have successfully completed well over 5,000 hours on the test bench. The first pre-production marine engines of this type will be delivered at the end of 2017 to Strategic Marine’s shipyard in Vietnam, which will install them in catamarans for the Netherlands-based shipping company Rederij Doeksen. The first certified series-production gas engines are scheduled to leave the factory as of 2018. Damen Shipyards are to equip a new harbour tug with the new engines and the local public utility in Constance, Stadtwerke Konstanz, will take delivery of the first engines of the 8-cylinder version for a new Lake Constance ferry at the end of 2019.
