Project Overview
Emergency troubleshooting and overhaul of a main sea water pump while the vessel remained afloat, with the objective of restoring cooling-water circulation and avoiding an unplanned off-hire period.
Operational Challenge
The vessel reported abnormal vibration, reduced discharge pressure and leakage from the mechanical seal of the main sea water pump. Because the pump served critical cooling consumers, prolonged operation in this condition created a risk of overheating and interruption of vessel operations. The repair had to be completed onboard and within a restricted operational window.
Technical Assessment
The MGQ technical team attended the vessel, reviewed operating records and carried out visual, dimensional and mechanical checks. Initial inspection indicated bearing wear, seal deterioration and possible shaft misalignment. The pump was isolated in coordination with the vessel crew and a safe dismantling plan was agreed before work commenced.
Detailed Scope of Work
- Emergency onboard attendance and job planning
- Isolation, draining and dismantling of the pump
- Inspection of casing, impeller, shaft, bearings and seal components
- Shaft run-out and dimensional checks
- Replacement of bearings, gaskets and mechanical seal
- Cleaning and correction of mating surfaces
- Reassembly, alignment and controlled tightening
- Operational testing and monitoring of pressure, temperature, leakage and vibration
Execution Methodology
The pump was dismantled in a controlled sequence and all components were tagged for traceability. The shaft and impeller were cleaned and inspected for scoring, corrosion and distortion. Bearings and sealing elements were renewed, mating faces were prepared, and the unit was reassembled with attention to shaft freedom and coupling alignment. After reinstatement, the system was gradually returned to service and monitored under operating load.
HSE Controls
Work was performed under vessel permit-to-work procedures, including machinery isolation, lockout/tagout, safe lifting, housekeeping and use of appropriate PPE. Open flanges and pipe connections were protected to prevent contamination and accidental ingress.
Quality Assurance and Inspection
Inspection findings, replaced components, alignment checks and final operating readings were recorded. The completed pump was accepted after stable discharge pressure, normal bearing temperature, no visible leakage and acceptable vibration were confirmed.
Project Outcome
Cooling-water circulation was restored within the available operational window. The vessel avoided an extended delay and the pump returned to stable service after completion of the overhaul and onboard performance test.
