Wärtsilä is to provide a full propulsion package for a new passenger vessel being built by Fr Fassmer for Germany-based Reederei Cassen Eils.

The new ferry will run on liquefied natural gas (LNG) using two nine-cylinder Wärtsilä 20 dual-fuel (DF) medium-speed engines.

It will operate between Cuxhaven and the island of Helgoland in Germany, where it must minimise exhaust gas emissions due to its proximity to Lower Saxon Wadden Sea national park.

AG EMS is the parent company of Reederei Cassen Eils. Chairman Dr Bernhard Brons said its operations need to be ecologically friendly with the lowest possible emissions, as the vessel must fulfil the IMO regulations regarding SOx and NOx emissions in the North Sea’s Emissions Control Area.

"The vessel can operate very efficiently and without restrictions in the emissions regulated areas."

"At the same time, perfect manoeuvrability and reliability are most important. Thanks to Wärtsilä’s dual-fuel technology with its built-in redundancy, the vessel can operate very efficiently and without restrictions in the emissions regulated areas," Brons added.

Wärtsilä will supply its LNGPac fuel bunkering and supply system with related safety and automation systems, in addition to propulsion systems.

The ferry will feature Wärtsilä’s patented Cold Recovery System, which uses the latent heat of LNG in the ship’s air-conditioning systems to reduce the amount of electricity consumed by cooling compressors, saving operational costs and increasing overall efficiency.

Wärtsilä Ship Power sales general manager Matthias Becker said the over-riding priorities for this new ferry are environmental performance, energy efficiency and the reliability of the propulsion machinery, as the ferry will be in daily service.

The vessel is scheduled for delivery in the first half of 2015.
