Lessons learned

  1. Collision by a service operation vessel damaged a turbine, so operators should review approach procedures and exclusion zones around offshore turbines.
  2. Vessel contact with a turbine caused damage, so operators should require structural inspection of the tower and foundation before return to service.
  3. Service vessel collision at an offshore wind farm carries risk of damage, so insurers should check crew training records for close-quarters manoeuvring.
