Undesired event
After an event such as this, planned maintenance routines should be checked to ensure they are adequate.
Comments
The vessel was working in an open water situation and there was no loss of position.
Considerations
- Useful reporting of an undesired event that did not result in a loss of position.
- After an event such as this, planned maintenance routines should be checked to ensure they are adequate.
- Particulars of the vessel are unknown however it might have been possible to power the two remaining bow thrusters from either side of the switchboard and therefore maintain redundancy with just two bow thrusters.
- This was a well executed operation that ensured full thruster redundancy options were made available prior to operations resuming.
