Finnish technology group, Wärtsilä, have been chosen to supply the main engines and LNG fuel gas supply systems for two new LNG-fuelled escort tugs.
The tugs are being constructed in Sanmar Shipyards, Turkey for Canadian company HaiSea Marine, a joint venture between the Haisla Nation and Seaspan Marine Transportation.
Designed by Robert Allan Ltd. Naval Architects and Marine Engineers, the ships are expected be two of the most environmentally advanced escort tugs operating in the coastal waters of British Columbia in Canada.
About the project, Mark Keneford, General Manager, Sales, Wärtsilä Marine Power, said, “This project aligns closely with Wärtsilä’s efforts to develop and promote environmentally sustainable technologies, and to support the global decarbonisation of shipping.”
“We are pleased to continue our strong relationship with Seaspan Marine, and are proud to have our solutions included in the Robert Allan RAstar design for this project.”
Wärtsilä 34DF dual-fuel engines will power the vessels. Operating with LNG fuel, the engines will be fitted with Wärtsilä’s NOx selective catalytic reduction (SCR) system to restrict nitrogen oxide emissions.
Delivery to the shipyard is scheduled in 2022 and will also include Wärtsilä’s LNGPac fuel storage, supply and control system.
A factor in Wärtsilä being awarded the contract was its previous successful equipment delivery for two in-service ferries operated by SeaSpan Ferries, another Seaspan affiliated company.
