AMSA Requirements for 15 ppm Bilge Alarms – Is Your Smart Bilge System Ready?

The Australian Maritime Safety Authority (AMSA) has published guidance for Port State Control inspections of oily water separators and 15 ppm bilge alarms under MEPC.107(49).

For Rivertrace customers, there are two key areas to consider:

  • OCM response time – the response time must not exceed 5 seconds.
  • Sample flow monitoring – the installation must operate fail-safe if sample flow to the Oil Content Monitor (OCM) is disrupted.

Not every Smart Bilge system needs upgrading. What you need depends on the version and configuration already installed onboard.

What does my system need?

Smart Bilge+ with flow switch

No upgrade required for these AMSA inspection points.

The Smart Bilge+ control module meets the required response-time performance, and the flow switch provides sample-flow monitoring.

Smart Bilge+ without flow switch

STD SMART BILGE+ - 230V,115V, 24V

Control module has the orange + after SMART BILGE = No changes needed
Flow switch: Add where suitable sample-flow monitoring is not already provided.

Optional Flowswitch

Depending on the age and configuration of your system, you may need:

  • an upgraded control module to meet the required response time; and/or
  • a flow switch where suitable sample-flow monitoring is not already fitted.

Check the serial number before ordering an upgrade.

Part numbers would start with: 109073 or 109158 or 109159

Not sure which system you have? Send Rivertrace:
  • a photo of your Smart Bilge unit;
  • the serial number;

Our team can confirm what equipment is already installed and whether any additional components are required.

AMSA Marine Notice 2025/06 – Testing and inspection of oil filtering equipment (MEPC.107(49))

Note: AMSA compliance relates to the complete onboard OWS installation and its operation. This guide specifically explains the Rivertrace Smart Bilge equipment that may be relevant to the inspection points highlighted by AMSA.
