SCHOTTEL RECEIVES LARGE ORDER FOR CANADIAN TUGS

SCHOTTEL RECEIVES LARGE ORDER FOR CANADIAN TUGS

Wednesday, July 28, 2021 

Schottel of Germany has been contracted to deliver a total of 10 rudder propellers and two transverse thrusters for five tugs ordered by HaiSea Marine in Canada which are to be built at Sanmar Shipyards in Turkey.

 

The propulsion units will be installed in two LNG-fuelled escort tugs and three battery-powered harbour tugs, which will provide ship assist and towing services to LNG carriers stopping at a new LNG export facility in Kitimat, British Columbia. The vessels were ordered by HaiSea Marine, a partnership between the Haisla Nation and Seaspan, and are scheduled to enter service in 2023.

Capt Jordan Pechie, Senior Project Manager, HaiSea Marine, said: “Choosing Schottel as our propulsion supplier brings us one step closer to delivering on the promise we made to the Haisla Nation. These vessels represent the future; both quality and longevity are key. Every component on these vessels was carefully selected to ensure that this project will be generational.”

Hakan Tunç, Procurement Manager, Sanmar, said: “The collaboration between Sanmar and Schottel dates back to 2004. Since then we have equipped many of our state-of-the-art vessels with quality propulsion solutions from Schottel. These new projects are taking the cooperation between Sanmar and Schottel to a new level.”

The fleet will consist of two RAstar 4000-DF dual-fuel (LNG and diesel) escort tugs and three ElectRA 2800 electric harbour tugs. Designed by Robert Allan Ltd. (RAL), the LNG tugs will be built in Sanmar Shipyards Altinova while the electric tugs will be built in Sanmar Shipyards Tuzla.

Each of the two dual-fuel escort tugs will be equipped with two Schottel SRP 610 CP RudderPropellers featuring an input power of 3,000kW with a propeller diameter of 3.2m. To further enhance manoeuvrability, each vessel will be fitted with a 250kW Schottel STT 170 TransverseThruster. Measuring 40m in length and providing around 100t of bollard pull, they will be the most powerful escort tugs on Canada’s west coast. In addition, they will feature an exhaust after-treatment system in full compliance with IMO Tier III emissions standards.

Each of the three battery electric tugs will be propelled by two 2,100kW Schottel SCD 460 CombiDrives with four-bladed propellers of 2.6m diameter. This thruster setup enables the harbour tugs to achieve a bollard pull of approximately 70t. The ElectRA 2800 harbour tugs will operate in unison at a new LNG export facility and will be 'first-of-their-class' battery-powered electric tugs. They are designed to perform their regular ship-berthing and unberthing missions using onboard battery power with a capacity of around 5,240 kWh. The ElectRA 2800 harbour tugs will be 28m in length.

With an ample supply of clean hydroelectric power available at Kitimat, the harbour tugs will be able to recharge from dedicated shore charging facilities at their berths between dockings, effectively resulting in near-zero emissions when running on batteries. GHG emissions from the new tugs are expected to be significantly lower (54% and 24% respectively) than diesel-powered alternatives.
