Summary
Two related Walk-to-Work gangway incidents occurred during offshore wind personnel transfers. Hydraulic stiction caused uncontrolled slewing and a collision with the vessel crane. Subsequent modifications introduced an automation logic error that prevented retraction during connection preparation. The flash describes hydraulic adjustments, revised operating procedures and manufacturer testing; neither incident caused injury.
