Svitzer has contracted Uzmar shipyard in Turkiye to build a first of its kind methanol-battery tug for delivery in the second half of 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.
The tug will be based on Svitzer’s TRAnsverse tug design and will 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 80% of its operations using its battery-electric powertrain and conduct up to 25% of Svitzer’s work in the port of 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 Canadian naval architect, Robert Allan Ltd, the tug will feature an overall length of 34.9m, providing stability and capacity. It will deliver bollard pull ahead of 85t and utilise escort steering and braking forces rated at 150t and 200t, respectively, measured at 10 knots. With a gross tonnage of around 806t it 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 safe, efficient and reliable operations in a location with the right availability of these two power sources. Aiming to become the world’s most sustainable port, the Port of Gothenburg was considered the right 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.
Gareth Prowse, Head of Decarbonisation, Svitzer, said: “The launch of a first-of-its-kind newbuild project with our partners at Uzmar Shipyard is a significant milestone for our decarbonisation ambitions. We are proud of the work we have done with our technology suppliers and engineering consultants to develop the tug to this point. The battery electric tug will mean we can deliver our services to customers in the Port of Gothenburg with significantly lower carbon emissions, and still to the highest operational and safety standards.”
Kasper Nilaus, CEO Svitzer, said: “Applications for battery solutions are expanding at an unanticipated pace, and we see it becoming an important power option in the sustainability transition. This battery tug will bring a new dynamic to our operations. There will not be a one-size-fits-all solution for us to meet our ambitious decarbonisation targets, and equipped with this new power technology we have yet another option for how to significantly reduce emissions across the many global ports and terminals we operate in. In this way, we continue to develop our strategies for fleet-wide decarbonisation while constantly ensuring safe, reliable marine services to Svitzer customers.”
A Noyan Altug, CEO Uzmar, concluded: “Our close working partnership with Svitzer on planning and developing this newbuild project will see our shipyard deliver one of the most advanced tugs in the global fleet using new technologies and specifications. At Uzmar, we recognise the importance of reducing carbon emissions in the maritime sector, and we are fully aligned with Svitzer’s ambitious decarbonisation strategy. This project represents a significant step forward in that journey. By integrating cutting-edge technologies and sustainable practices, we are not just building a tug; we are helping to shape the future of green maritime operations. For Svitzer, our expert team will continue to deliver sustainable building excellence.”
