Rivertrace.
Oil content monitoring and 15 ppm bilge alarms for MARPOL Annex I discharge control. Supplied, commissioned and serviced by Green Marine across the Gulf of Mexico.
Overview
Discharge monitoring
you can defend.
Rivertrace builds oil content monitors and 15 ppm bilge alarms — the instruments that decide whether bilge water goes overboard or back to the tank, and that produce the record proving which happened.
Green Marine supplies the monitors, carries the cells, sensors and sample-line components most often needed, and services the units aboard: calibration, function testing and fault diagnosis.
What we supply
Rivertrace equipment
and the parts behind it.
Green Marine supplies the equipment and carries the components most often needed on the units we support.
15 ppm bilge alarms
Alarm units meeting the MARPOL Annex I discharge limit for machinery-space bilge water.
Cells and sensors
Measuring cells, optical components and sensors held for the units we support.
Calibration & testing
Scheduled calibration, function testing of the automatic stopping device, and written records.
Typical applications
Where it goes
to work.
01
Engine room bilge systems
Machinery-space bilge water discharge monitoring and control.
02
Offshore support vessels
Units working in areas with strict discharge control.
03
MARPOL Annex I compliance
Vessels required to demonstrate discharge below 15 ppm.
04
Retrofit and replacement
Replacing obsolete or failed monitors on existing separators.
Green Marine support
The manufacturer
relationship, on the Gulf Coast.
Working directly with Rivertrace means parts, documentation and technical answers come from the source rather than a guess. Green Marine specifies the range, holds the parts most commonly needed on the vessels we support, and escalates to the manufacturer when a fault needs engineering input.
Every service visit is documented, so the next person to open the equipment knows what was found and what was done.
- Supply and replacement
- Commissioning and start-up
- Troubleshooting and repair
- Calibration and function testing
- Parts identification and sourcing
- Written service reporting
How to start
From nameplate
to a written quote.
Green Marine works from whatever information you have aboard — a spec-out for a newbuild or a replacement part for a running unit.
- 01
Tell us the vessel
Vessel name or hull, the system aboard, and whether it is a supply, replacement or service enquiry.
- 02
Send what you have
Make, model, serial number, part number — or a photo of the nameplate. Whatever you have is enough to start.
- 03
We spec and price
Written quote against the correct build and revision, with lead times and any commissioning support quoted separately.
- 04
Delivered and documented
Shipped where you need it, with the paperwork you need to close it out.
Start here
Request a
quote.
Every quote is answered by an engineer, not a form email. Send the vessel, the system and anything you have off the Rivertrace nameplate — that is enough to price against.
Field service, spare parts and commissioning can all be quoted from the same request.
- Sized and priced against the actual unit aboard
- Written response with lead time and options
- Direct manufacturer support if engineering input is needed

Next step
Have a nameplate
but no model?
Send us a photo of the plate and the vessel it is on. We identify the correct build, revision and part number from there.
