Wärtsilä has won contracts to power Canada’s most environmentally advanced escort tugs
It secured contracts to supply the main engines and LNG fuel gas supply systems for two LNG-fuelled escort tugs being built to support gas carriers at a new export facility in British Columbia.
The two escort tugs are being built to a Robert Allan design for Canada’s HaiSea Marine, a joint venture between the Haisla Nation and Seaspan Marine Transportation.
Sanmar Shipyards in Turkey placed the orders for main engines, selective catalytic reduction (SCR) systems and LNG packages with Wärtsilä in April 2021.
Each escort tugboat will be powered by Wärtsilä 34DF dual-fuel engines operating with LNG fuel which will be fitted with Wärtsilä’s SCR equipment to restrict emissions of nitrogen oxides. Wärtsilä will also supply its LNGPac fuel storage, supply and control system to Sanmar’s shipyard in 2022.
“This project aligns closely with Wärtsilä’s efforts to develop and promote environmentally sustainable technologies, and to support the global decarbonisation of shipping,” said Wärtsilä Marine Power general manager for sales Mark Keneford.
Wärtsilä has previously delivered similar equipment for two in-service ferries operated by Seaspan Ferries in Canada.
Sanmar is building these escort tugs to RAstar 4000-DF design, each with an overall length of 40 m and a bollard pull of 100 tonnes.
The dual-fuel tugs will escort and assist carriers at the LNG Canada export facility in Kitimat, east of Prince Rupert, British Columbia. This LNG production and export plant is the largest private sector investment in Canadian history and is scheduled to open in 2023.
Sanmar is also building electric-driven harbour tugs at its Altinova shipyard for HaiSea Marine’s operations in Kitimat to a new design, ElectRA 2800. These 28-m tugs will have a bollard pull of 70 tonnes and batteries with capacity of 6,102 kWh.
Designed for ship docking and unberthing missions on battery power, they will recharge from dedicated shore-charging facilities supplied from clean hydroelectric power at their berths between jobs, effectively resulting in zero emissions when running on batteries.
