Maintenance needs to be carefully managed during DP operations and avoided whilst the vessel is operating on DP.
Comments
-
At approximately 15:55, the ETO came to the bridge and asked the Senior DPO permission to enter the electronics room to check the UPS batteries.
-
The SDPO gave permission, not knowing the detailed work scope of the ETO.
Considerations
- Both planned and unplanned work on DP equipment should be subject to a permit to work system.
- Maintenance routines need to be carefully managed during DP operations and planned maintenance of any DP equipment should be avoided whilst the vessel is operating on DP.
