Facts about the operational hub
Some components needed to maintain wind turbines will be stored in a warehouse on hub site. Other equipment will arrive from manufacturers on a ‘just in time’ basis to be loaded onto the new vessel.
Once mobilised, the SOV will spend up to 28 consecutive days on station at the wind farm, where it will be able to service six to eight wind turbines each day. Crews of technicians from DONG Energy and turbine supplier Siemens will work on a two weeks on, two weeks off, shift pattern.
With the SOV in position, technicians will walk safely to work from the vessel’s open deck to work on the wind turbines using an innovative motion-compensated gangway. This gangway will remove the need for climbing up and down vertical access ladders as happens when traditional crew transfer vessels push on to the foundation of a turbine.
The bespoke SOV’s are expected to set the blueprint for the way in which offshore wind farms are maintained in future, offering significant safety and operational efficiency benefits. They will incorporate a containerised warehouse for the storage of equipment spares, tools and consumables.
