Svitzer has contracted Uzmar shipyard to build a first of its kind battery-methanol tug for delivery in H2 2025. The 6MWh battery-powered tug will be deployed in Gothenburg and provide zero-emission services across a quarter of Svitzer’s operations in the port.
Svitzer, a leading global towage provider, has today announced that it has signed a contract with the Turkish shipyard Uzmar to build a world-first battery-methanol tug. The tug will be based on Svitzer’s innovative TRAnsverse tug design and feature a 6MWh battery supported by dual fuel methanol engines for back-up and range extension.
The escort duty tug is expected to conduct more than 90% of its operations using its battery-electric powertrain and conduct up to 25% of Svitzer’s work in the port of Gothenburg. Svitzer’s innovative TRAnsverse tug design will allow the battery-powered tug to operate more efficiently than internal combustion engine powered tugs of a traditional design.
Designed in collaboration with naval architect, Robert Allan Ltd, the tug will feature an overall length of 34.9 meters, providing substantial stability and capacity. It will deliver an impressive bollard pull ahead of 85 tonnes and utilise escort steering and braking forces rated at 150 and 200 tonnes, respectively, measured at 10 knots. With a gross tonnage of approximately 806 tonnes and powered by a 6MWh battery system, the tug will be capable of achieving speeds of up to 14 knots.
Continuing developments in alternative power technologies convinced Svitzer that the combination of battery power and methanol engines can ensure both safe, efficient and reliable operations in a location with the right availability of these two power sources.
With an aim to become the world’s most sustainable port, the Port of Gothenburg was considered the perfect location for the new tug. The port is making significant investments to provide the necessary shore power charging options, and methanol is already being bunkered at the port. As such, Gothenburg has all the ingredients for safe and stable operation of the tug for many years to come.
