Maine ferry operator Casco Bay Lines has committed to an integrated hybrid-electric power and propulsion solution from ABB for its new vessel, in a technology step change along one of the longest-established ferry routes in the United States
The new ferry is expected to cut up to 800 tons of carbon dioxide per year, significantly improving air quality in Portland, Maine.
The new 50-metre ferry will feature ABB Marine & Ports’ hybrid power, propulsion and a shore charging system, supporting diesel-electric and zero-emissions battery-powered modes, as well as a combination of both. With the ferry operating in zero-emission mode, the passengers will benefit from a smoother, cleaner and quieter ride.
In line with US governmental commitments to reduce the environmental impact of public service transit systems nationwide, the ferry project has been partially funded by federal and state grants, with a 15-vehicle and 599-passenger capacity vessel to replace an existing diesel-powered ferry for the Portland–Peaks Island service along the coast of Maine.
“This contract is an important milestone for ABB Marine & Ports hybrid-electric propulsion in the US ferry market,” says Bruce Strupp, Senior Account Manager, New Build, ABB Marine & Ports. “Momentum for lower carbon footprint ferry operations continues to grow worldwide, and ABB is honoured that its integrated electric, digital and connected solutions are being considered integral as more and more US operators replace obsolete vessels to match regulatory and societal demands.”
“Hundreds of thousands of passengers ride the Casco Bay Lines ferry between Portland and Peaks Island each year,” says Hank Berg, General Manager of Casco Bay Lines. “Increasingly, ferry passengers prioritise sustainability as a service expectation, in addition to reliability and comfort. The ability to switch to zero-emission battery power in port is also a clear environmental benefit for residents in Portland and Peaks Island. We look forward to a close collaboration with ABB and we can’t wait to see the end result.”
Within its integration, engineering, automation and equipment supply roles, ABB will deliver the award-winning Onboard DC Grid™ power distribution system to give full control over when and how the vessel uses its diesel generators, the 904-kWh battery energy storage system or a combination of the two to optimise energy consumption at any load. ABB is also supplying an automated shore charging system for installation at the Port of Portland, which automatically connects at the dock and will not require any additional port time to charge the vessel.
Smooth running, remote monitoring and predictive maintenance will be supported through the inclusion of the ABB Ability™ Remote Diagnostics System in the vessel.
Hybrid and electric solutions for ferries are on the rise, with over 130 battery-powered ferries already in operation and more than 90 on order, according to the Maritime Battery Forum. ABB’s complete, integrated solutions for hybrid and electric vessels are increasingly selected by ferry operators worldwide and in the US Recent successes have included a fleet renewal project for Washington State Ferries, the largest ferry system in the country, while ABB also supplied power and propulsion package for the latest “Maid of the Mist” Niagara Falls tour ferries – the first fully-electric vessels built in the US.
