Observation
Vessel operators should note that this type of event continues to occur and might consider whether additional barriers should be put in place.
Considerations
- This event highlights the possible consequences of deselecting critical DP system buttons. Significant changes to any system should not be made during critical phases of an operation.
- It was considered highly likely that the DPO was performing multiple tasks when the surge button was unknowingly deselected.
- Tools are available within position reference systems to monitor vessel position and alarm if the vessel moves outside a set limit.
- Vessel operators should note that this type of event continues to occur and might therefore consider whether additional barriers should be put in place for critical switches.
