AYK Energy will deliver the innovative battery system to Turkish shipyard Uzmar, which is building the vessel for global towage provider Svitzer. 

“We’re extremely pleased to have won the contract from Uzmar to work on this project, which is a trailblazer in the sector,” said Chris Kruger, founder, AYK Energy.

“This once again underlines the confidence the marine industry has in AYK to deliver. The combination of battery power and methanol engines is safe, efficient, and reliable – and we’re proud to lead this innovation for the sustainability transition.”

Proven design

The battery-powered tug is based on Svitzer’s TRAnsverse tug design and will rely on its battery-electric powertrain for more than 90% of its operations.

The vessel’s design will also allow the battery-powered tug to operate more efficiently than internal combustion engine powered tugs of a traditional design. 

Dual-fuel methanol engines will serve as a backup, providing extended range and reliability. The vessel, with a gross tonnage of approximately 806 tonnes, will reach speeds of up to 14 knots.

The groundbreaking tug, set for delivery in the second half of 2025, will operate in the Port of Gothenburg and provide zero-emission services across a quarter of Svitzer’s Swedish operations.
