Inspector Detail
▸
Common issues
- Wash water pH or turbidity readings drifting outside compliance limits
- Spray nozzle or tower packing fouling from soot/particulate build-up reducing SOx removal efficiency
- Wash water circulation pump wear or cavitation from particulate-laden water
- Corrosion of scrubber tower and ducting internals from acidic wash water
- CEMS sensor fouling or calibration drift affecting SO2/CO2 ratio compliance readings
- Bypass/exhaust routing damper faults affecting gas flow control
Inspection checklist
- Check CEMS calibration status and compare readings against reference gas
- Inspect wash water pH/turbidity monitoring and the compliance log
- Open tower manholes to inspect for scale, soot and corrosion where access allows
- Inspect spray nozzles and demister for fouling
- Check wash water pump seals and bearings for leakage or vibration
- Verify bypass damper operation and position feedback
- Confirm the exhaust gas cleaning system record book is up to date
- Inspect exhaust ducting and expansion joints for corrosion
Service intervals
| CEMS calibration | per class/maker requirement, typically quarterly with an annual full calibration - confirm against maker manual |
| Wash water pump seal/bearing check | annually or at first sign of leakage/vibration |
| Tower internal inspection | annually or opportunity-based at dry-docking |
| pH/turbidity sensor cleaning | monthly or per observed fouling rate |
Critical spares
- Wash water circulation pump seal kit
- Spray nozzle set
- pH and turbidity sensor probes
- Bypass damper actuator
- CEMS sample line filters
Safety
- Acidic or caustic wash water contact hazard during sampling and maintenance
- Confined space entry for tower internal inspection - verify gas-free before entry
- Hot ducting and tower surfaces near the exhaust connection
- Chemical dosing system hazards where caustic soda is used for pH control
Class survey
Class reviews the EGCS Onboard Monitoring Manual, wash water discharge and CEMS calibration records against MEPC.259(68); confirm current survey scope and EGCS certificate validity with the vessel's class notation.
