ABB has secured a contract with Polish shipyard Remontowa Shipbuilding to supply power distribution and propulsion systems for seven new all-electric double-ended ferries being built for Caledonian Maritime Assets Ltd (CMAL).
The vessels, due for delivery between late 2027 and early 2029, will be equipped with ABB’s Compact Onboard system and are part of CMAL’s Small Vessel Replacement Program, which aims to modernize the company’s fleet and improve sustainability across Scotland’s West Coast ferry network.
Under the agreement, ABB will also provide shore power systems for multiple CMAL terminals, starting with Kennacraig and Port Askaig, enabling vessels to draw energy directly from the local grid while berthed, and eliminate emissions from idling engines.
Each 50m vessel will serve routes in the Clyde and Hebrides region, carrying up to 200 passengers and 24 cars – except one, which will accommodate 250 passengers and 16 cars. The ferries are co-funded by the Scottish government and represent a key milestone in the UK’s push to decarbonize port and ferry operations.
“We appreciate ABB’s expertise in power, propulsion and electrification,” said Michal Jaguszewski, director of commerce at Remontowa Shipbuilding. “Combined with our shipbuilding capabilities, we will make this a great set of vessels to advance low-emission transportation across the western Scottish ferry network.”
ABB’s Compact Onboard DC Grid has been designed for vessels with limited space, offering a distributed configuration that simplifies integration while improving efficiency. The system features a short-circuit-tested marine DC switchboard and HES880 inverters, combined with ABB’s AXME Marine Motors – compact solutions offering high power density and reduced weight.
Power and energy management, alarm and monitoring functions are built into the same platform, allowing for streamlined operation and greater efficiency across propulsion and onboard systems.
Once in service, the ferries will use ABB’s shore connection systems to power hotel loads while docked, cutting fuel use, CO2 emissions, and noise pollution in port communities.
“These ferries will bring increased capacity and the benefits of clean, fully electric propulsion to island and rural communities in Scotland,” said Jim Anderson, director of vessels at CMAL. “ABB’s experience in integrating ship electrification and shore connection systems is well placed, and we look forward to taking delivery of the vessels.”
Juha Koskela, president of ABB Marine & Ports, added, “This order confirms the capability of our Compact Onboard DC Grid to meet the power needs of smaller vessels. By enabling efficient and flexible electrification of inland and coastal ships, the system contributes directly to maritime decarbonization.”
