The Finnish company will supply all the main equipment for the also Finnish shipping company whose ro-los are being constructed at the Chinese WuHu Shipyard.

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. The company's LNGPac storage and supply system will be located below deck in order to preserve cargo space.

In addition, the vessels will be equipped with Wärtsilä's ProTouch controls and Eco Control to enable accurately synchronised engine speed and propeller pitch. These integrated technologies will be supported via the company's Data Collection Unit (WDCU) with its cloud based services and remote monitoring to optimise 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. Furthermore, the propulsion efficiency will be optimised 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," Luuk Hijlkema, Account Manager, Sales, Wärtsilä Marine, added.

Bore's 7,000 dwt-big brand-new ships will be 120 m-long and will have the highest 1A ice class. They'll ply in the Baltic and North seas on behalf of the Finnish forest company UPM. The first ro-lo is scheduled for delivery in mid-2021, while the last in 2022.

"We appreciate Wärtsilä's support and deep technological know-how, which have played a key role in developing these world-class vessels. We are proud to add these environmentally sustainable and fuel efficient ships to our fleet," Jörgen Mansnerus, VP, Marine Management, Bore, commented.
