Inspector Detail
▸
Common issues
- Oil content meter (OCM) sensor fouling or drift causing false 15 ppm alarm trips or, worse, missed exceedances
- Sample line or strainer blockage from sludge/emulsified oil affecting sensor readings
- Automatic overboard discharge valve failing to close fully on a high-oil signal
- Optical/measuring cell window contamination requiring cleaning
- Control unit alarm or data logging fault, which is a MARPOL record-keeping problem, not only a nuisance alarm
- Water dosing or humidification control instability on the NOx-reduction side affecting reduction performance
Inspection checklist
- Verify oil content meter calibration against the maker's reference/check fluid
- Function-test the automatic overboard discharge valve on a simulated high-oil alarm and confirm it shuts
- Confirm alarm and discharge recording (OCM data logger) is functioning and storing records correctly
- Inspect sample lines and strainers for blockage
- Clean optical cell/window per maker procedure and re-check zero reading
- Verify the DNV type-approval certificate is valid and the installed configuration matches the approved arrangement
- Check control unit firmware/software version against any outstanding service bulletins
Service intervals
| Oil content meter calibration | typically annually, per the equipment's approved test procedure - confirm interval on the type-approval certificate |
| Sample cell/optical window cleaning | as fouling requires, commonly every few weeks in continuous service |
| Discharge valve function test | at each periodical survey |
Critical spares
- Oil content meter sensor/cell (sealed unit, no generic substitute)
- Sample pump
- Discharge valve solenoid/actuator
- Sample line strainer elements
- Control unit power supply/fuses
Safety
- Bilge water can carry hydrocarbon vapour - treat sample point work as a potential flammable atmosphere
- Incorrect calibration risks an illegal discharge and a MARPOL Annex I non-compliance
- Live electrical work at the control panel during function testing
Class survey
Note on this record: the catalogued type 'Radar Level Gauge' / category 'Cargo Level & Temperature Gauging' does not match this equipment family - the listed products (PureNOx, PureBilge, PureBilge Compact, Flex) are Alfa Laval NOx-reduction and bilge water treatment systems, not level gauges; the content above addresses the actual equipment. Bilge water treatment/oil content monitoring equipment is normally subject to an annual function test and calibration record to satisfy MARPOL Annex I discharge requirements; NOx-reduction equipment is tied to the vessel's EIAPP certificate and NOx Technical File. Only limited technical detail is available for this specific EPC70 catalogue entry (DNV TA certificate TAA00003BY only) - confirm model-specific figures against Alfa Laval's own documentation before use.
