September 24 (Renewables Now) - Danish offshore wind major Ørsted A/S (CPH:ORSTED) has invested in a Scottish developer of a motion compensated lifting system that changes the way technicians access offshore wind turbines.
Specifically, Ørsted has acquired a 22.5% stake in Pict Offshore, a Fife-based spin-off from height safety innovator Limpet Technology. The firm has developed a motion compensated hoist solution, allowing technicians to transfer between small moving vessels and offshore wind turbines in a safe manner.
Ørsted’s goal is to help mature the technology, which is currently in the final stages of development. During the testing process, over 1,600 successful hoists have already been carried out at Ørsted sites.
At present, wind turbine technicians use Crew Transfer Vessels (CTVs) with boat landing and ladder, helicopters or motion compensated gangways to reach the base of a turbine, or offshore structure. Ørsted notes that the latter option is not applicable on all sites, while the use of helicopters is not suitable for all types of troubleshooting tasks and is more expensive. The use of CTVs, in turn, is not as safe and efficient is Pict Offshore’s option.
