Wartsila delivers low-noise propulsion for Canada’s OFSVs

(HELSINKI) — The technology group Wartsila has supplied specialized propulsion solutions for three offshore fisheries science vessels (OFSVs) built for the Canadian Coast Guard at Seaspan Shipyards in British Columbia. Low-noise propulsion is very important for the vessels’ primary mission, which is to carry out fisheries research. As such, Wartsila designed the propellers to deliver a high-cavitation inception speed to comply with these low underwater radiated noise requirements. Delivery of the third of these new OFSVs took place on Oct. 8.

Wartsila’s depth of experience in designing and producing low-noise, highly efficient propeller solutions, as well as its leading market position in technologies for research vessels, were key factors in the award of the contract.

“Wartsila is proud to have been selected as the propulsion technology partner to Seaspan Shipyards for this important project, which has now culminated with delivery of the third vessel. In addition to enabling quiet propulsion, our fully integrated solutions also reduce both fuel consumption and emissions. The 120 Wartsila Canada employees are also proud of the more than $7 million in industrial regional benefit offsets we have thus far brought to the Canadian economy during this project,” said Mark Keneford, general manager, Wartsila Marine Power Sales, United States and Canada.

“These OFSVs showcase Seaspan Shipyard’s capabilities as a world-class builder of state-of-the-art vessels for the Canadian Coast Guard. Wartsila has been a trusted supplier throughout the OFSV program. Their equipment is key to enabling these vessels to effectively carry out their fisheries science missions with minimal environmental impact,” said Paul Thomas, vice president, Coast Guard programs, Seaspan Shipyards.

The Wartsila scope of supply for each of the three vessels includes the propulsion solution, comprising the custom-designed fixed pitch propeller, the shaft line assembly, plus seals and bearings, and the transverse thruster with e-motor and variable speed drive.

Wartsila equipment is installed in approximately 85 percent of all Canadian Coast Guard vessels. This includes the major propulsion and engine-related solutions in some 50 percent of the fleet.
