Zurich, Switzerland / Glasgow, Scotland — Global technology leader ABB has been awarded a contract by Remontowa Shipbuilding S.A. to supply state-of-the-art power distribution and propulsion systems for seven all-electric double-ended ferries owned by Caledonian Maritime Assets Ltd (CMAL) in Scotland. The vessels will be delivered between late 2027 and early 2029, marking a major step toward zero-emission maritime transport in the region.

In addition to onboard systems, ABB will also provide shore connection technology across several CMAL ferry terminals — beginning with Kennacraig and Port Askaig — enabling seamless and energy-efficient charging while minimizing environmental impact and operational costs.

Electrification Advancing Scottish Maritime Sustainability

The new ferries form a cornerstone of CMAL’s Small Vessel Replacement Programme (SVRP), an initiative designed to modernize the Scottish small vessel fleet and upgrade related port infrastructure. Each 50-meter vessel will serve one of nine routes across the Clyde and Hebrides network, carrying up to 200 passengers and 24 vehicles (with one vessel accommodating 250 passengers and 16 cars).

“ABB’s expertise in power, propulsion, and electrification — combined with our excellence in shipbuilding — will deliver a new standard of clean, efficient, and resilient ferry transport across Scotland’s west coast,” said Michal Jaguszewski, Director of Commerce at Remontowa Shipbuilding S.A.

Compact Onboard DC Grid™: Optimizing Power for Space-Constrained Vessels

The vessels will integrate ABB’s Compact Onboard DC Grid™, a distributed power system designed specifically for ships with limited space. This technology simplifies system integration, enhances energy efficiency, and ensures operational flexibility through smart power management and monitoring.

Featuring AXME Marine Motors, the system delivers high power density in a lightweight, compact design — ideal for small to mid-sized electric and hybrid vessels. This comprehensive solution combines reliability, performance, and adaptability, helping shipowners accelerate their electrification and decarbonization goals.

Shore Connection Systems Enabling Zero-Emission Port Operations

ABB’s shore connection systems will allow berthed ferries to connect directly to the local power grid, enabling the complete shutdown of onboard engines. This capability drastically reduces CO₂ emissions, fuel consumption, and noise pollution in port areas — significantly improving air quality and the environmental footprint of ferry operations.

Co-funded by the Scottish Government, this initiative represents a vital milestone in the UK’s strategy to decarbonize ports and achieve net-zero maritime operations.

“These vessels will bring increased capacity and the advantages of clean, all-electric propulsion to Scotland’s island and rural communities,” said Jim Anderson, Director of Vessels at CMAL.
“ABB’s integrated approach ensures efficient cooperation between onboard power systems and shore infrastructure — a critical factor for the success of this program.”

Driving Global Maritime Decarbonization

“This order demonstrates how ABB’s Compact Onboard DC Grid™ meets the specific power and space requirements of short-distance ferries,” noted Juha Koskela, President of ABB Marine & Ports.
“By enabling flexible and efficient electrification, ABB contributes directly to the global decarbonization of coastal and inland shipping while reinforcing our leadership in shore connection solutions.”
