Wartsila 31 engines will power Mols-Linien RoPax

SEPTEMBER 28, 2016 — The 158 m car and passenger ferry ordered at Finnish shipbuilder for Rauma Marine Constructions (RMC) by Danish operator Mols-Linien, (see earlier story) will be powered by two eight-cylinder Wärtsilä 31 main engines.

Introduced last year, the Wärtsilä 31 has been recognized by Guinness World Records as the world’s most efficient four-stroke diesel engine. Additionally, its modular design that enables a significant reduction in maintenance requirements and costs, with the first major overhaul is scheduled at 32,000 running hours.

“The selection of this particular engine was based on the unique efficiency for the required output, and also the favorable maintenance intervals it allows,” says Flemming Kristensen, Technical Director, Mols-Linien A/S.

Wärtsilä has worked closely with Mols-Linien for a number of years , providing waterjets to all of its fast ferries.

“We have a strong track record in supplying waterjets to Mols-Linien for powering their fleet of high speed catamarans. With the introduction of the Wärtsilä 31, we are now extending this cooperation to include the engines for their vessels,” says Jens Karlsson, General Manager, Sales, Wärtsilä Marine Solutions.

The Wärtsilä engines are scheduled to be delivered to the shipyard in July 2017, and the ship is due to enter into service in summer 2018. It will sail on Danish waters between Rønne on the island of Bornholm and Køge, and between Rønne and Sassnitz, Germany.
