Damen introduces a fully electric SOV with offshore charging capabilitiesDamen Shipyards Group has launched a fully electric Service Operations Vessel (SOV), measuring 70 by 17 metres, with offshore charging capabilities.
 
To achieve offshore charging, Damen has partnered with UK-based MJR Power & Automation. MJR has developed a 4MW charger connector, sufficient for a 70-metre vessel. The company is also working on a scaled-up 8MW, version that will enable charging of larger vessels up to 90 metres.

The charging system uses the motion-compensated gangway to create a connection between the vessel and a turbine or substation offshore. The gangway is controlled from the wheelhouse, requiring no manual interaction with charging equipment. Charging is carried out while the vessel is in a low-power, so-called ‘green’ DP mode, requiring less energy than the hotel load. A full charge typically requires energy produced in just a few hours by a single turbine. The system is designed according to internationally recognised safety standards, including IEC/IEEE 80005-1. Additionally, it is about to obtain DNV AIP (Approval In Principle) and is designed in accordance with forthcoming offshore charging standards under collaborative development by DNV UK and Norway.

The SOV 7017 E features a 15MWhr battery, sufficient to power the vessel during a full day of operations. The battery is lithium iron phosphate (LFP). In the event that the vessel cannot access electricity for a short period, the SOV 7017 E features full redundancy and is able to continue operations with conventional diesel propulsion. The vessel has all the storage space, workshops, and deck space to undertake the broad scope of transportation and work expected of it. Its 60 cabins provide accommodation for crew and up to 40 technicians.
