What happened?
During lifting operations close to an offshore wind turbine generator (WTG), a call came in telling teams in the area to prepare for crew transfer onto the same turbine.
There was a separate team up inside the nacelle of the WTG, unaware of the vessel nearby doing the lifting operations.
Once the crew had transferred to the WTG, lifting operations were resumed with lifting bags being craned onto the transition piece of the WTG.
The crew on board begin to disconnect the load from the lifting bags.
During this process, the main crane boom is hit by the idling blade from the yawing nacelle causing debris to fall from the Blade and a minor hydraulic leakage on the vessel.
-
Why did it happen?
Vessel approach procedure was not initially adhered to by the vessel, crew or the team inside the nacelle.
There was no dedicated crew member on the vessel acting as a spotter for the operations.
No one on the team inside the nacelle was watching the blades or aware of the vessel outside.
-
What did they learn?
Review and, where necessary, update the vessel approach procedure at the site.
Drills and practice exercises to be completed by technicians and crew members to familiarise themselves with the new procedure.
Officer of the watch position to become mandatory on all vessels over 15m (49 ft) long.

Ask yourself or your crew
Are you aware of any operations happening nearby that may affect your own operational success?
Do you have the correct personnel in place to ensure safety and success of the operation?
Are you aware of the positioning of machinery in reference to your own work?
