ODME measurement and alarms are verified onboard.

The Marsen ODME-2000 is an advanced Oil Discharge Monitoring Equipment system designed to ensure ships comply with international discharge regulations while protecting the marine environment. This system continuously measures the oil content of ballast and slop water before overboard discharge, accurately tracking discharge quality and automatically managing control actions based on real-time data.

Built around a robust controller and oil content meter paired with a hydraulic package, sampling pump and motor, the ODM-2000 uses differential pressure flow measurement and GPS input to calculate and regulate oil discharge. Its self-cleaning design and intrinsically safe components reduce maintenance needs, while fast response and vibration-insensitive operation support reliable performance even in challenging sea conditions.

In line with IMO and MARPOL Annex I requirements, oil discharge must meet strict limits (oil content below regulatory thresholds and proper recording of discharge data such as rate, time and ship position). Continuous records must be kept onboard and presented during port state control and classification surveys. Regular calibration and verification of the oil content meter are necessary to maintain accuracy and compliance. Classification societies typically require calibration at renewal surveys, and industry practice recommends annual checks with full recalibration every five years for optimal performance.

Our ODME services are available on board vessels calling at major ports across Spain, Gibraltar, Netherlands, France, Germany, Italy, Bulgaria, Turkey and Romania, with port stops including Algeciras, Valencia, Barcelona, Marseille, Rotterdam, Hamburg, Genoa, Piraeus, Varna, Izmir and many others. Whether you need commissioning, functional testing, calibration, or verification support, we help ensure your Marsen ODM-2000 meets inspection standards and operates reliably throughout your voyages.
