Oil Content Meter & Bilge Alarm Calibration

Calibration and functional verification of 15 ppm oil content monitors, bilge alarms, recorders, and automatic stopping devices.

15 ppm bilge alarm and oil content monitor calibration

The oil content monitor (OCM) is a critical part of the oily-water separator discharge arrangement. It measures oil content, records operating data, activates the 15 ppm alarm, and initiates recirculation or automatic stopping when discharge water exceeds the permitted limit. Calibration and functional testing help demonstrate that the monitor, sample line, alarm, recorder, and stopping device operate together rather than as isolated components.

MARPOL survey context

MARPOL Annex I regulation 14 and IMO resolution MEPC.107(49) govern 15 ppm bilge separators and alarm arrangements on applicable ships. The calibration status may be reviewed during IOPP surveys and Port State Control inspections. MEPC.107(49) equipment should retain calibration and service records onboard, and many administrations and makers apply a calibration validity period not exceeding five years, with checks after repair or replacement. The vesselโ€™s approved equipment documentation, flag instructions, and maker procedure determine the exact requirement.

Typical calibration scope

  • Identify monitor, measuring cell, software version, recorder, separator, and automatic stopping arrangement
  • Inspect sample flow, flushing, cleanliness, seals, electrical connections, and alarm outputs
  • Apply maker-approved reference methods or calibration tools and verify indicated values
  • Function-test the 15 ppm alarm, time delay, three-way valve, recirculation, data recording, and position feedback
  • Issue a service and calibration certificate recording serial numbers, standards, readings, and next due date

Information to provide

Send the vessel, port, OCM and separator maker, model and serial number, type-approval reference, last certificate, current alarm or fault details, spare-cell status, and survey deadline. Advise whether the separator can be operated during attendance and whether class or flag witnessing is required. Calibration does not correct a contaminated sampling system or defective stopping device, so allow for troubleshooting and spares when faults are already known.
