The pair of dual-fuel 95-ton bollard pull escort tugs ordered by HaiSea Marine at Turkey’s Sanmar Shipyards will feature Wärtsilä engines and LNG fuel gas supply systems.
The Robert Allan Ltd RAstar 4000-DF design escort 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 (SCR) 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.
Wärtsilä has previously delivered similar equipment for two in-service ferries operated by Seaspan Ferries, like HaiSea Marine another Seaspan affiliated company. The successful performance of these ferries and Wärtsilä’s life cycle support capabilities in Canada, were cited as being important considerations in the award of the escort tug contract.
“This project aligns closely with Wärtsilä’s efforts to develop and promote environmentally sustainable technologies, and to support the global decarbonization 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,” says Mark Keneford, General Manager, Sales, Wärtsilä Marine Power.
