Operations were conducted according to procedures. It was concluded that the procedures for this operation needed to be modified to limit the amount of rope in the water to prevent bow thruster entanglement.
Considerations from the above event:
- Operations were being conducted within limits that allowed for disconnection to be completed in a controlled manner using the redundancy of thrusters.
- All vessel types are reminded to review procedures that might affect DP operations, particularly those covering downlines, hoses, ropes, etc.
