Wärtsilä is to fit a German car and passenger ferry with dual fuel engines as part of a retrofitting contract awarded by German shipyard, Brenn-und Verformungstechnik Bremen GmbH (BVT).

Wärtsilä will convert the MV Ostfriesland, owned by Aktien-Gesellschaft EMS, so that it can use liquefied natural gas (LNG) as a fuel.

Matthias Becker, general manager, sales, Wärtsilä Ship Power, told The Motorship: “The main reason for the conversion was the lengthening of the vessel to increase its capacity and the need for the vessel to operate in the SECA and NECA sulphur and nitrogen controlled areas.”

It will be fitted with two 6-cylinder Wärtsilä 20DF dual fuel generating sets and a Wärtsilä LNGPac. The engines will run on LNG as the main fuel, but have the capacity to switch to conventional liquid fuels if needed.

The LNGPac comprises onboard LNG bunkering, storage tanks and handling equipment with related safety and automation systems.

“The ship will also get a new aft ship with optimised hull lines to improve the efficiency of the ship. This will increase cargo capacity by 20% on deck,” Mr Becker added.

The new engines will significantly reduce its environmental footprint as LNG reduces CO2 output by 20%, NOx by 85% and SOX and particles to almost 100%.

This will allow it to sail on the Lower Saxon Wadden Sea National Park, an ecologically sensitive UNESCO World Heritage listed area in the south-eastern part of the North Sea.

The retrofitting will be carried out during the second quarter of 2014 and is expected to be completed within seven weeks.
