A SYSTEMATIC PROCESS OF EVENTS IN DECOMMISSIONING A BOP CONTROL UNIT WOULD BE:
- Hazard and Risk assessment conducted.
- Permits prepared.
- System removed from service and proven inert:
- Prime mover electric driven pump and air operated pumps permanently isolated.
- Nitrogen accumulators bled down to atmosphere and bladder valves removed.
- Oil reservoir drained and lines bled down to lowest point.
- Lines split and fluids drained.
- Tagged as “out of service” and in “decom state”.
- Components and spare parts identified for retention.
EQUIPMENT CAN BE EVALUATED WITH CONSIDERATION TO:
- Retaining in storage
- Breaking down into spare parts
- Transfer to another facility.
- Re-sale value
These mud pumps were dismantled and critical components retained in storage
On completion, systems and equipment are formally handed over to the principal decommissioning contractor
