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

Holding position, losing references
While approaching a turret-moored, weather-vaning offshore installation (FPSO), in preparation for cargo operations, a DP equipment class 2 vessel experienced significant rolling of up to 15–20° due to a long-period swell close to the vessel’s natural roll period, resulting in a resonance effect
