Schottel has secured contracts to supply propulsion for ive tugs Sanmar Shipyards is constructing to support a new LNG export terminal in Canada
This tugboat-building project consists of two LNG-fuelled escort tugs and three battery-powered harbour tugs to be constructed in Turkey which will be used to assist LNG carriers into a new export facility in Kitimat, British Columbia from 2023.
HaiSea Marine, a partnership between the Haisla Nation and Seaspan ULC, will operate these tugs, which are designed by Robert Allan Ltd.
Schottel will supply RudderPropellers (SRP), CombiDrives (SCD) and transverse thrusters (STT) for these tugs.
The fleet will consist of two RAstar 4000-DF LNG dual-fuel escort tugs and three ElectRA 2800 electric harbour tugboats. For the RAstar 4000-DF escort tugs, Schottel will supply two SRP 610 thrusters with controllable-pitch propellers and one STT 170 unit. SRP 610 CP has an input power of 3,000 kW with a propeller diameter of 3.2 m. An STT 170, with 250 kW of input power, will provide enhance manoeuvrability to each vessel.
These 40-m tugs will have 100 tonnes of bollard pull to become the most powerful escort tugs on Canada’s west coast. To reduce their environmental footprint further, they will feature an exhaust after-treatment system in full compliance with IMO Tier III emissions standards.
Schottel is also supplying two SCD 460 CombiDrives for the three battery-electric tugs. They each have power input of 2,100 kW and four-bladed propellers of 2.6 m diameter. Propulsion units will enable these 28-m ElectRA 2800 harbour tugboats to achieve a bollard pull of 70 tonnes. Battery power on board will have 5,240 kWh capacity and will be charged from renewable power ashore.
With an ample supply of clean hydroelectric power available at Kitimat, the harbour tugs will recharge from dedicated shore charging facilities at their berths between dockings, resulting in near-zero emissions when running on batteries.
“These vessels represent the future; both quality and longevity are key,” said HaiSea Marine senior project manager Captain Jordan Pechie. “Every component on these vessels was carefully selected to ensure this project will be generational.”
HaiSea’s LNG tugs will be built in Sanmar’s shipyards in Altinova while the electric tugs will be built in Sanmar’s shipyard in Tuzla.
