An operator's perspective on the highs and lows of hybrid ferry operations

CalMac Ferries have been operating three hybrid diesel / electric / battery ferries for eight years resulting in 23 years of operational experience. These ferries operate across Scottish Lochs and plug in and charge the batteries overnight which provides approximately 20% of the propulsive power during the timetable operations. This presentation will cover lessons learnt from operating hybrid ferries, the positives and challenges faced. It will review the commercial aspects and will also look to the future to discuss what may be coming next and how this experience is being used to prepare for all electric Scottish ferries.
