Summary
A vessel struck a wind turbine transition-piece platform twice after changing from dynamic positioning to independent joystick control in worsening weather. Thrusters returned to zero pitch during changeover. The flash examines handover awareness and judgement, subsequent system testing, and revisions to procedures, familiarisation and passage planning.
