DECKMA OMD-24 Oil Content Meter (15ppm Bilge Alarm)
Manufacturer
DECKMA Hamburg GmbH
Country of Origin
Germany
Product Type
Oil Content Meter (OCM) / 15ppm Bilge Alarm
Marine Application
Oily Water Separator (OWS) Monitoring & MARPOL Compliance System
Product Introduction
The DECKMA OMD-24 Oil Content Meter is one of the most widely installed and internationally approved 15ppm Bilge Alarm systems used on commercial vessels worldwide.
Manufactured by DECKMA Hamburg GmbH, Germany, the OMD-24 continuously measures the oil concentration in bilge water discharged through an Oily Water Separator (OWS). The system ensures that overboard discharge complies with MARPOL Annex I regulations by monitoring oil content and automatically activating alarms when oil concentration exceeds permitted limits.
Due to its reliability, high accuracy, and worldwide acceptance by classification societies, the OMD-24 has become a standard environmental protection device on tankers, bulk carriers, container ships, offshore vessels, and passenger ships.

What Is the DECKMA OMD-24?
The OMD-24 is a marine-approved oil content monitoring device designed to continuously analyze the oil concentration of water discharged overboard through an Oily Water Separator.
Its main functions include:
- Oil content measurement
- Bilge discharge monitoring
- Automatic alarm generation
- MARPOL compliance verification
- Environmental protection
- Automatic discharge control
The system measures oil concentration in parts per million (ppm) and ensures discharge remains below the internationally accepted 15ppm limit.

Working Principle
The OMD-24 uses advanced optical measurement technology to detect oil droplets suspended in water.
Operating Sequence
- Water exits the Oily Water Separator.
- Sample water flows through the OMD-24 measuring cell.
- Optical sensors analyze oil contamination.
- Internal electronics calculate oil concentration.
- The result is displayed in ppm.
- Alarm outputs are monitored continuously.
- If oil content exceeds preset limits, alarm and control outputs activate.
This process allows real-time monitoring of discharge water quality.
