SCHOTTEL will deliver a total of ten rudder propellers and two transverse thrusters to the Turkish shipyard Sanmar Shipyards. These are installed in two LNG-powered escort tugs and three battery-operated harbour tugs.
The ships, commissioned by the Canadian HaiSea Marine, a partnership between the Haisla Nation and Seaspan ULC, will provide assistance and towing services for LNG tankers docking at the new LNG export station in Kitimat, British Columbia. All five tugs are scheduled to go into operation in 2023.
Captain Jordan Pechie, Senior Project Manager at HaiSea Marine:
“Choosing SCHOTTEL as the propulsion supplier brings us one step closer to delivering on the promise we made to the Haisla Nation. These ships represent the future; both quality and durability are crucial Every component on the ships has been carefully selected to ensure this project will last for generations. ”
Hakan Tunç, Procurement Manager at Sanmar:
“The cooperation between Sanmar and SCHOTTEL goes back to 2004. Since then we have equipped many of our modern ships with high-quality drive solutions from SCHOTTEL. These new projects raise the cooperation between Sanmar and SCHOTTEL to a new level Level.”
The fleet will consist of two RAstar 4000-DF dual-fuel (LNG and diesel) escort tugs and three ElectRA 2800 electric harbor tugs. Designed by Robert Allan Ltd., the LNG tugs are built at the Sanmar shipyard in Altinova, while the electric tugs are built at the Sanmar shipyard in Tuzla.
Each of the two dual-fuel escort tugs is equipped with two SCHOTTEL rudder propellers type SRP 610 CP with an input power of 3,000 kW and a propeller diameter of 3.2 m. To further improve maneuverability, a SCHOTTEL TransverseThruster type STT 170 (250 kW) will be installed in every ship.
With a length of 40 m and a bollard pull of around 100 t, they will be the most powerful escort tugs on the Canadian west coast. They also have an exhaust after treatment system that meets the requirements of the IMO Tier III emissions standard.
Each of the three battery-operated electric tugs is powered by two SCHOTTEL CombiDrive Type SCD 460 (2,100 kW each) with four-bladed propellers with a diameter of 2.6 m. With this drive configuration you can achieve a bollard pull of approx. 70 t.
The ElectRA 2800 port tugs will be used together at the new LNG export facility and will be the first battery-powered electric tugs in their class. They are designed in such a way that they perform their regular tasks when putting on and taking off with the help of battery power with a capacity of around 5,240 kWh. The ElectRA 2800 port tugs will be 28 meters in length.
Since there is sufficient clean electricity from hydropower available in Kitimat, the port tugs can be charged at their berths between the berthing processes using special shore charging stations, which leads to almost zero emissions in battery operation. The greenhouse gas emissions of the new tugs are expected to be significantly lower (54% and 24% respectively) than with diesel-powered alternatives.
