The technology group Wärtsilä will supply the engines for a new LNG-powered research vessel being built for the German government. Wärtsilä will also supply exhaust cleaning systems based on selective catalytic reduction (SCR) technology and the LNGPac system for complete fuel gas handling. The SCR technology will be needed when the engines are running on conventional marine diesel fuel if the vessel exhausts its supply of LNG on long voyages.
The vessel is under construction at the Fassmer shipyard in Germany and will be owned by Bundesamt für Seeschifffahrt und Hydrographie (BSH), the Federal Maritime and Hydrographic Agency. The new 75-meter ship, the ‘Atair’ will replace her 30 year old namesake, and will be the first German research vessel operating on LNG. The Wärtsilä equipment is scheduled to be delivered to the yard in mid-2018, and the vessel will enter service in early 2020.
The full scope of Wärtsilä’s supply for the ‘Atair’ is two 6-cylinder Wärtsilä 20DF dual-fuel engines capable of running on either LNG or conventional liquid fuels, one 6-cylinder Wärtsilä 20 engine, two exhaust cleaning systems, and a Wärtsilä LNGPac fuel storage, supply, and control system. The engines will have Tier III classification since the dual-fuel engines comply with this classification when running in gas mode. Furthermore, the engines will be double elastically mounted to minimize the noise.
“Our dual-fuel technology is unique when it comes to small bore medium speed engines, and the extended service intervals and economic fuel consumption of the Wärtsilä 20DF engine enable lower operating costs than is possible with high speed engines. We have worked closely with the Fassmer shipyard and are proud to have once again been selected to supply the machinery and equipment for this important project,” said Lars Anderson, Vice President, Engine Sales, Wärtsilä Marine Solutions.
