The SMART BILGE 15ppm Oil Content Monitor with 15ppm bilge alarm was developed in 2005 for real time oil analysis to meet and exceed the requirements for MEPC.107(49) regulations.
The SMART BILGE+ 15ppm monitor and alarm is made up of 2 key components:
- the SMART BILGE+ ‘Module’
- the SMART ‘CELL’ measuring cell
Developed by Rivertrace, the SMART CELL utilises a unique Detector Array Technology. This enables the OCM to run real time oil analysis of all three oil types (HFO, Diesel and Emulsions) simultaneously without the need for re-calibration.
This innovative design allows for simple routine maintenance of the OCM, while maintaining optimal operating conditions.

The SMART CELL utilises a unique Detector Array Technology, developed by Rivertrace, allowing the OCM to analyse all three oil types (HFO, Diesel and Emulsions) simultaneously without the need for re-calibration. This innovative design allows for simple routine maintenance of the OCM while maintaining optimal conditions.
Optical cell fouling is recognised as a leading cause of monitor malfunction or incorrect reading. A manual cell cleaning device is included as standard to easily enable routine maintenance.
Replacement calibrated measuring cells can be purchased for easy change over on board the vessel and calibration check kits enable the crew to demonstrate the monitor is within factory calibration to PSC Surveyors.
SMART Bilge+ Monitor Key Features
- Digital Certifications
- Automated electronic calibration reminders
- Over 50 approved service centres worldwide for calibration checks and service
- Separate Calibrated SMART CELL to allow easy exchange
- Test button for demonstration of alarm points to port state control
- Real time oil analysis.

SMART Bilge+ Monitor – 15ppm Bilge Alarm Rivertrace Type
SMART Bilge+ Monitor Application
- MEPC.107(49) Bilge Water Discharge
- DNV Clean Design Notation
- Oily Water Separator
- Deck Drains Discharge
- Rig Slop Tank Discharge
- Air Cooler Drains Discharge.
SMART Bilge+ Monitor Flexible Solution
- 5PPM Alarm – The Smart Bilge+ is readily available as a 5ppm version Type Approved to DNV Clean Design Notation.
- Autoclean – our pneumatic autoclean solution has been designed to ensure the measuring cell glass tube his kept free from fouling. Cell fouling is recognised as a leading cause of monitor malfunction. Fitting the autoclean removed the need for the ship’s crew to remember to clean the cell manually.
- Flowswitch – The flowswitch option has been designed to ensure that bilge water is flowing through the measuring cell when in monitoring mode. An error is shown on the display if there is no flow. The flowswitch monitors the flow of water through the cell. This ensures that the flow cannot be shut off accidentally or maliciously. In case of no flow, the Smart Bilge+ will close the overboard discharge valve.
- GPS HARDWARE – SMART BILGE+ can be connected directly with a GPS Input to record the location of every event in the IMO logs and automatically logged in E-ORB via RT CONNECTED
- Overboard Flow Meter – Using an overboard flowmeter the SMART BILGE+ can record the total discharge volume into the IMO logs and automatically logged in E-ORB via RT CONNECTED
- SMART CONNECT – MEPC.107(49) OWS Discharge data can be captured and shared digitally to the cloud which can then be integrated into electronic ORBs.
- Hazardous Environments (Zone 1 & 2) – The SMART BILGE+ can be offered in an explosion proof cabinet.
