New product
A 15 PPM Bilge Alarm, also known as an Oil Content Monitor (OCM) or bilge-water oil monitor, is a key pollution-prevention instrument installed in connection with a ship's Oily Water Separator (OWS).
Its purpose is to continuously measure the oil content of treated bilge water before discharge overboard. Modern type-approved systems are designed around the 15 ppm discharge-control requirement associated with MARPOL Annex I and IMO Resolution MEPC.107(49). Rivertrace describes its current SMART BILGE as a 15 ppm oil-content monitor for bilge-water discharge, while JOWA states that SeaGuard monitors separator effluent and is approved to MEPC.107(49).
SM MARINE SERVICE™ supports complete 15 ppm bilge alarms, Oil Content Monitors, calibrated measuring cells, controllers, sensors, PCBs, valves and replacement components from multiple manufacturers.
Rivertrace Engineering's SMART BILGE family continuously monitors bilge-water oil concentration. Rivertrace states that the system is designed for OWS discharge monitoring under the 15 ppm requirement and uses SMART CELL detector technology.
Important replacement requirements can include the control unit, calibrated measuring cell, SmartCell wiper, manual-clean assembly, controller PCB components and related sampling hardware. Rivertrace's current support documentation identifies calibrated measuring cell part 109171, SmartCell wiper 109039, manual-clean assembly 109857, and controller PCB main fuse 109167.

The DECKMA OMD-24 belongs to the well-known DECKMA marine Oil Content Monitor / bilge alarm family.
DECKMA Hamburg specializes in 15 ppm Bilge Alarm Monitors and related marine oil-monitoring equipment.
Older OMD-24 installations remain important in the marine spare-parts market because vessels may need:
• Complete monitor
• Measuring cell
• Control electronics
• Sampling components
• PCB assemblies
• Solenoid valves
• Cables and connectors

The DECKMA OMD-2005 is a bilge-water Oil Content Monitor used for monitoring OWS discharge.
For SEO and technical accuracy, this product should be described as a 15 ppm Bilge Alarm / Oil Content Monitor, not as an engine-crankcase Oil Mist Detector.
Typical legacy requirements include:
• Complete OMD-2005 unit
• Measuring cell
• Monitor/controller
• Sampling equipment
• Valves
• Electronic components

The Brännström BilgMon 488 is a compact 15 ppm Bilge Alarm designed for marine OWS discharge monitoring.
Brännström states that the BilgMon 488 is type-approved to meet IMO Resolution MEPC.107(49), and its compact size makes it suitable for retrofit installations. A particularly useful feature is its detachable measuring cell, which can be replaced with a calibrated cell when required.

The DECKMA OMD-2008 is a modern DECKMA Oil Content Monitor / Bilge Alarm system.
The system is intended to monitor oil content in treated bilge-water discharge. Common configurations include OMD-2008, OMD-2008 EV, EVA and EVFC, depending on valve, cleaning and flow-control arrangements.
DECKMA OMD-2008 Oil Content Monitor / 15ppm Bilge Alarm
The operating principle is straightforward:
JOWA describes this same basic arrangement: the bilge alarm monitors separator effluent and the discharge is stopped when oil content exceeds the permitted limit.
The 15 ppm threshold is associated with machinery-space bilge-water pollution-control requirements under MARPOL Annex I.
Rivertrace explains that 15 ppm means 15 parts of oil per million parts of solution by mass, and that the OCM is used to verify treated bilge water before discharge.
This means the Bilge Alarm is not simply a convenience instrument—it is an important part of a vessel's pollution-prevention and discharge-control arrangement.
Depending on model, a system may include:
• Main Control Unit
• Oil Content Monitor / Controller
• Measuring Cell
• Optical Detector / Sensor
• Sample Chamber
• Sample Flow Assembly
• Solenoid Valve
• Three-Way Valve
• Auto-Flush Arrangement
• Flow Switch
• Cleaning Brush / Wiper
• Filters
• Relay Outputs
• Data Logger
• Power Supply
• PCB / Electronic Boards
• Cables & Connectors
Different manufacturers use different cell and sampling technologies, so compatibility must always be verified by exact model and part number.
The measuring cell is one of the most commonly requested 15 ppm Bilge Alarm spare parts.
Typical reasons for replacement include:
• Contaminated optics
• Calibration failure
• Damaged sensor electronics
• Age-related deterioration
• Incorrect or unstable PPM reading
• Repeated detector fault
• Regulatory calibration requirements
Rivertrace provides a replaceable calibrated SmartBilge measuring cell, while Brännström specifically promotes the BilgMon 488's detachable measuring cell for easy calibration-by-replacement.
First verify whether the Oily Water Separator is actually producing compliant water.
Possible causes include:
• Separator malfunction
• Excessive oil contamination
• Dirty or contaminated measuring cell
• Air bubbles in sample water
• Incorrect sample flow
• Sensor/calibration problems
Never assume a high PPM alarm is false without checking the actual discharge condition.
Inspect:
• Sample quality
• Measuring cell cleanliness
• Alarm setpoint
• OWS performance
• Cell calibration
• Sample-line contamination
Possible causes include:
• Blocked sample pipe
• Closed valve
• Failed sample pump
• Clogged filter
• Flow-switch fault
• Solenoid-valve problem
Check:
• Incoming power
• Fuse
• Power supply
• PCB
• Terminal connections
• Display/control unit
Typical causes include:
• Dirty optical cell
• Air bubbles
• Contaminated sample chamber
• Incorrect flow rate
• Calibration drift
• Electronic sensor fault
Inspect:
• Fresh-water connection
• Solenoid valve
• Cleaning sequence
• Valve coil
• Flow condition
• Controller output
JOWA, for example, specifically includes automatic flushing to keep the sensing section clean.
Bilge Alarm accuracy is critical because discharge decisions rely on the measured PPM value.
Depending on manufacturer and regulatory/service requirements, calibration may involve:
• Onboard verification
• Certified calibration
• Factory-calibrated measuring-cell exchange
• Calibration certificate replacement
• Zero/check procedure
• Functional alarm test
Rivertrace SMART BILGE stores calibration-related information and IMO-required operational data, while Brännström's BilgMon 488 supports replacement of the detachable measuring cell with a calibrated unit.

These systems are widely used aboard:
• Container Ships
• Bulk Carriers
• Oil Tankers
• Chemical Tankers
• LNG/LPG Carriers
• Cargo Ships
• Offshore Vessels
• Passenger Ships
• Workboats
• Merchant Vessels
They form part of the ship's:
Oily Water Separator System • Bilge Water Treatment System • Pollution Prevention System • Overboard Discharge Monitoring Arrangement
A reliable Bilge Alarm helps:
• Detect non-compliant oily-water discharge
• Initiate alarms before overboard discharge continues
• Support automatic discharge shutoff
• Provide monitoring data
• Support inspection and compliance requirements
• Protect the marine environment
• Verify OWS performance
Rivertrace notes that modern monitoring arrangements can also record operational and alarm information required for compliance records.
A 15 PPM Bilge Alarm is an Oil Content Monitor that measures oil concentration in treated machinery-space bilge water before overboard discharge.
In this application, the terms are commonly used together. The Oil Content Monitor performs the measurement, while the system provides alarm and discharge-control functions.
No. In this context, OMD-2008 is an Oil Content Monitor / 15 ppm Bilge Alarm, not a crankcase Oil Mist Detector.
