Incat and ABB to Develop Lightweight Hybrid-electric Ferry

Australian shipbuilder Incat Tasmania will work with technology company ABB to explore building an electric ferry with hybrid-electric propulsion which could transition to battery power as shore charging becomes available.

Seeking a transitional route to zero-emission operations for the ferry segment, Incat and ABB will evaluate the suitability of the ‘Incat 148E’ - a 148-meter-long roll-on roll-off passenger (RoPax) catamaran for operating in hybrid mode as well as adapting to full battery operation at a later stage.

Conceived by Revolution Design, Incat’s in house design office, the 148E would be built in Australia to DNV class, operating at speeds of up to 21 knots. It would feature ABB’s Onboard DC Grid power distribution, ABB Ability Power and Energy Management System (PEMS), 800xA distributed control systems, a remote diagnostic system, and two Azipod propulsion units.

The hybrid-electric propulsion solution envisioned for the Incat 148E will involve the vessel’s diesel engine charging a shipboard battery, whose output provides the flexibility in power management to improve fuel efficiency and cut emissions. When shore charging facilities are available, Incat-built electric ferries would make greater use of batteries, with project goals envisaging installed battery power of up to 30MWh.

Robert Clifford, Founder and Chairman of the Board, Incat Group of Companies, said, “Lightweight Incat ships use up to 40% less power than an equivalent steel ship, which means up to 40% less emissions. We’ve done extensive work in applying our excellence in ferry design to the specifics of electric propulsion. ABB is the ideal partner to help Incat realize our ambition to lead the shortsea shipping industry into a more sustainable future.”

"There is no single solution where shipping’s emission challenges are concerned and we have to be imaginative in this transition to more sustainable ferry operations,” said Palemia Field, Global Segment Manager, Ferries, ABB Marine & Ports. "Considerations of what a future ferry could or should look like and how it would operate are bringing bold thinking to market. ABB’s innovative electric solutions are an enabler for forward-looking companies like Incat.”
