Wärtsilä to Supply Technology to New LNG-Fueled German Research Ship

 

Wärtsilä is to supply the engines for a new LNG fueled 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 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 contract was signed with Wärtsilä in June 2017.

The new ship Atair will replace her 30 year old namesake and will be the first German research vessel operating on LNG fuel. Wärtsilä will also supply the engines and SCR systems for three German Federal police boats to be built at the Fassmer yard.

Wärtsilä’s will supply 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, and all the engines will be compliant when operating on diesel because of the Wärtsilä SCR systems. Furthermore, the engines will be double elastically mounted to minimise the noise. This special Wärtsilä technique will enable the ship to fulfil the DNVGL classification society’s ‘Silent R’ rating, thus allowing the sonar equipment to be used without disturbance from underwater radiated engine noise.

The Wärtsilä equipment is scheduled to be delivered to the yard in mid-2018, and the vessel will enter service in early 2020.
