Estonian shipbuilder Baltic Workboats has released details of its latest electric ferry offering, the Ferry 22 Electric.

The company states that the electric propulsion system, supplied by Danfoss Editron, is half the size of a conventional diesel-electric system, thanks to the use of compact propulsion motors. It notes that power can be automatically switched from the battery energy store to a backup genset in the case of failure, which can also be used to charge the batteries if there is a lack of shore power.

When docked, the vessel is charged via a tower and pantograph located on a floating pontoon. The vessel is secured with fixed length mooring lines and small amount of thrust is used, coupled with an automated positioning system to keep it located during charging.

Solar panels are installed in addition to hybrid grid and general service batteries. For optimum efficiency, the panels are connected to the system via a micro converter, and are located on an open roof section to allow for easy cleaning. According to Baltic Workboats, the solar panels provide sufficient energy to cover the entire energy needs of the vessel except the propulsion system.

The vessel will have a maximum speed of 16km/h and will be capable of sustained cruise at 14km/h, while carrying a crew of two and up to 100 passengers, including 40 seated. Stowage will also be provided for up to 40 bicycles.
