Kongsberg Maritime has selected AYK Energy to provide battery systems for four new fully electric Svitzer tugs
Marine battery manufacturer AYK Energy has announced further growth in the workboat sector after securing a new contract with Kongsberg Maritime to supply battery systems for four new fully electric Svitzer TRAnsverse tugs.
The agreement builds on AYK Energy’s previous involvement in five Svitzer hybrid-electric tug projects and further strengthens the company’s position in the growing market for battery-electric harbour vessels.
The four new tugs are being built at Cochin Shipyard in India and will each be equipped with an ABS-certified 4,838kWh OrionAN+ battery system. The contract also includes an option for a further four vessels.
AYK’s batteries will integrate into Kongsberg Maritime’s system, which includes the complete electrical and automation architecture of the tugs, including DC and AC switchboards, permanent magnet propulsion motors, K-Chief control systems and shore charging equipment.
AYK founder Chris Kruger said: “This is such an exciting moment for AYK. I’ve been working on this technology since 2012 with Svitzer’s four diesel electric hybrid tugs on the west coast of Australia. AYK is incredibly proud to be continuing our work with the visionary teams at Kongsberg Maritime and Svitzer on these highly advanced green powered TRAnsverse tugs”
“It’s only possible to bring technology to the mass market when the biggest operators invest in, and believe in, the battery systems ROI. The passion from all parties to change the industry for the better is really there.”
Mr Kruger said the guiding principle for AYK is always to listen to industry and keep design simple. “Vessel operators and integrators have told us they want more energy density and greater power without compromising safety.
“This is what we’ve worked so hard to achieve. Marine batteries, electric ships, are not an easy technology. The rugged conditions of the sea make it much more challenging than electric road vehicles.
“If a vessel suffers battery failure you cannot simply step out onto the road. That is why we’ve worked so closely with class and innovators like Kongsberg Maritime and Svitzer to bring lithium-iron-phosphate (LFP) chemistry to the market at scale.
The latest Svitzer link follows another major deal with the company after AYK supplied its ABS-certified AriesA 6MWh battery system for Svitzer Balder, built by Uzmar shipyard in Türkiye. The Balder is the world’s most powerful electric escort tug.
