Oil Content Meter & Bilge Alarm Calibration
in Sohar.
Request oil content meter & bilge alarm calibration at the Port of Sohar in Oman. vslSafety reviews the scope, location, schedule, and relevant qualification requirements before coordinating suitable independent service options.
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 vessel’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.
Local planning
Attendance at Sohar
Sohar is a deep-water industrial port handling container, bulk, liquid, and project cargoes. Marine attendance should be aligned with terminal safety requirements, access approval, equipment delivery, survey witnessing, and the vessel’s working schedule.
Availability, final scope, attendance method, and certificate acceptance are confirmed against the vessel’s dates and technical requirements. Submit the berth or anchorage, local agent, ETA and ETD so access and logistics can be checked before mobilisation.
