Wärtsilä to supply integrated solutions to three new short-sea vessels

0

The technology group Wärtsilä will supply all the main equipment for the first LNG-fueled short-sea roll-on, lift-off vessels to be operated by Finland-based Bore. Three ships have been ordered and are being built at the Wuhu Shipyard in China.

Wärtsilä has worked in close collaboration with both the owner and the naval architect to develop a vessel-optimized integrated LNG system. As a result it has been possible to locate a 250cbm Wärtsilä LNGPac storage and supply system below deck without compromising the cargo capacity.

The ships will be propelled by a Wärtsilä 34DF dual-fuel engine driving a Wärtsilä controlled pitch propeller (CPP) at variable speed, connected to a Wärtsilä SCV95 gearbox with an integrated power pack. In addition, the vessels will each be equipped with Wärtsilä ProTouch controls and Eco Control to enable accurately synchronized engine speed and propeller pitch. This delivers outstanding engine and propulsion efficiency, while the Eco Control operating mode can be selected for automated fuel savings while in transit.

These integrated technologies will be supported via Wärtsilä’s Data Collection Unit (WDCU) with cloud-based services and remote monitoring to optimize operability, fuel economy, and periodic maintenance.

“Our remote smart services provide state-of-the-art support for the ships’ integrated solution, which is another value-adding feature that we are providing for these vessels,” said Luuk Hijlkema, account manager, sales, Wärtsilä Marine.

“Furthermore, the propulsion efficiency will be optimized using Wärtsilä’s computational fluid dynamics (CFD) Opti Design to tailor the size of the aft appendages specifically to the hull design. This efficiency saves fuel and, therefore, also operating costs.”

“We appreciate Wärtsilä’s support and deep technological know-how, which have played a key role in developing these world-class vessels,” said Jörgen Mansnerus, VP, marine management at Bore. “We are proud to add these environmentally sustainable and fuel efficient ships to our fleet.”
