Rolls-Royce Provides Electric Propulsion System for Vehicle-Hauling Ferry


Luxury automaker Rolls-Royce is tackling the high seas with its latest electrified propulsion system.

Rolls-Royce Electric Ferry System

Rolls-Royce Electric Ferry System Called Azipull

Rolls-Royce will supply the Fjellstrand electric ferry with its Azipull (azimuthing pulling propeller) propulsion system.   The ferry will be operated by Norled and will transport vehicles and passenger between Lavik and Oppedal, Norway at speeds of up to 25 knots (29 mph).

The Rolls-Royce Azipull propulsion system, which utilizes pulling propellers, will pull the aluminum catamaran ferry with power coming from a 800 kW, 11-ton battery pack.

The trek between Lavik and Oppedal will take approximately 20 minutes and charging will take place while vehicles (up to 120)  and passengers (up to 360) are loading the ferry.  This provides only a 10-minute timfeframe to charge the massive vessel, which may seem to short to be possible, but high-capacity batteries, located at each port, will perform what’s called a “dump charge” to get the ferry ready for its next crossing before it departs.   While the ferry is en route, the batteries will be recharged at a rapid, but grid-acceptable rate.

Amazingly, this electric ferry, which will replace the current 2,000-hp diesel ferry, will eliminate the annual need for 264,000 gallons of fuel.

Correction: the Rolls Royce responsible for this propulsion system is not the “luxury automaker”. The car brand was sold to Volkswagen and then BMW some years ago.

The Rolls Royce you’re referring to is the global engineering conglomerate, who make jet engines, marine systems and defence equipment. The two Rolls Royces have not been part of the same company since 1998.
