If wind sensors are being shielded, this could have a greater influence on the vessel model when the centre of rotation is changed.

DPE 16.01 – Change of a vessel centre of rotation – Flowchart

Considerations

  • 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.
