Wärtsilä has been contracted to supply a range of equipment for the first LNG fuelled short-sea Ro-Lo (roll-on, lift-off) vessels to be operated by Finland based Bore Ltd, with the supply package to include a comprehensive data collection and analysis platform for remote support of operations.
Three ships have been ordered and are being built at the WuHu Shipyard in China. The ships will be propelled by a Wärtsilä 34DF dual-fuel engine and will employ a Wärtsilä controlled pitch propeller (CPP) and gearbox with an integrated power pack.
In addition, the vessels will each be equipped with Wärtsilä ProTouch controls and Eco Control to synchronise engine speed and propeller pitch, with users able to select the Eco Control operating mode for automated fuel savings while in transit.
These integrated technologies will be supported by Wärtsilä’s Data Collection Unit (WDCU), which connects to Cloud-based services and remote monitoring applications to help in optimising voyage performance, 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 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.”
The 120m ships will be chartered to Finnish forestry company UPM, and will operate in the Baltic and North Seas. They will have Finnish/Swedish Ice Class 1A classification and are scheduled for delivery starting from mid-2021.
