Considerations from the above event:
- The centre of rotation should not be changed during critical operations.
- Because of the likely increase in length of the lever to control heading, careful consideration regarding power availability and requirements is needed whenever the centre of rotation is changed.
- If wind sensors are being shielded this could have a greater influence on the vessel model when the centre of rotation is changed.
- Whenever possible field entry trials should be conducted with the same system configuration as that required for operations.
