The technology group Wärtsilä will supply the main engines and LNG fuel gas supply systems for two new LNG-fuelled escort tugs being built for Canada’s HaiSea Marine, a joint venture between the Haisla Nation and Seaspan Marine Transportation. The ships have been designed by Robert Allan Ltd. Naval Architects and Marine Engineers, and are under construction at Sanmar Shipyards in Turkey. They are expected to be two of the most environmentally advanced escort tugs operating in the coastal waters of British Columbia in Canada. The order with Wärtsilä was placed in April 2021. The two vessels will each be powered by Wärtsilä 34DF dual-fuel engines operating with LNG fuel. The engines will be fitted with Wärtsilä’s NOx selective catalytic reduction system to restrict emissions of nitrogen oxides. Wärtsilä will also supply its LNGPac fuel storage, supply and control system. The Wärtsilä equipment is scheduled for delivery to the shipyard in 2022.
