Germany’s first newbuild LNG powered seagoing vessel makes maiden voyage
The first ever newbuild liquefied natural gas (LNG) fuelled German seagoing vessel, which is powered by a complete Wärtsilä LNG propulsion solution, had its maiden voyage on December 11. The ship has been built at the Fr. Fassmer shipyard in Germany, Wärtsilä said in its press release.
The passenger ferry, owned by Reederei Cassen Eils GmbH, will operate between Cuxhaven and the island of Helgoland. This route takes the vessel close to the UNESCO World Heritage listed Wadden Sea National Park, an ecologically sensitive area in the south-eastern part of the North Sea. Because of the need to minimise exhaust gas emissions in this area, the ferry will operate primarily on LNG using two 9-cylinder Wärtsilä 20DF medium-speed dual-fuel engines.
In addition to the propulsion machinery comprised of the two engines, two gearboxes and two controllable pitch propellers, Wärtsilä has also supplied its LNGPac fuel bunkering and gas supply system with related safety and automation systems. Of special note is the use of Wärtsilä’s patented Cold Recovery System, which utilises the latent heat of LNG for the ship’s air conditioning systems, thereby reducing the amount of electricity consumed in cooling compressors. This provides significant operational savings and an increase in overall vessel efficiency, while adding to the environmental benefits of the Wärtsilä solution.
Reederei Cassen Eils is a member of the AG EMS group of companies. Wärtsilä earlier retrofitted the company’s “Ostfriesland” car and passenger ferry for LNG operation. The retrofitted vessel had its maiden voyage on June 17.
