Complies with IMO Resolution MEPC. 60 (33) requirements.
The Deckma OMD-11 is a high-precision 15 ppm bilge alarm monitor designed to improve the reliability and operation of oily water separator (OWS) systems. Meeting the requirements of IMO Resolution MEPC.60(33) , the OMD-11 utilizes advanced solids suppression technology to distinguish between oil particles, solid particles, and water turbidity.

Per MEPC regulations, the unit must be calibrated and certified by an authorized Deckma service agent or replaced every 5 years. The calibration date is recorded on a certificate kept on board for Port State Control (PSC) inspections. deckma omd11 manual
Connect the sample inlet to the vertical section of the OWS overboard discharge line. Ensure the sample stream flows upward through the measuring cell to prevent air bubbles from trapping inside.
The Deckma OMD-11 is a legacy 15ppm (parts per million) bilge alarm monitor widely used in the maritime industry to comply with MARPOL regulations. Finding a comprehensive operational guide can be difficult since the manufacturer now focuses on newer models like the OMD-2005 and OMD-24.
What is the of your specific model (24V, 115V, or 230V)?
uses the to detect oil particles. A light source passes through the sample water; if oil is present, the light scatters. Highly sensitive sensors measure this scattered light and convert it into a digital ppm reading on the front panel. 3. Installation Guidelines Complies with IMO Resolution MEPC
To ensure accurate readings and prevent "false alarms," follow these manual-recommended installation steps:
utilizes light-scattering technology to distinguish between oil particles, solids, and water turbidity : 0–30 ppm (with trend indication up to 50 ppm). : Meets IMO MEPC.60 (33) standards.
Accessing, understanding, and correctly applying the is not just a maintenance task; it is a legal and safety imperative. This article breaks down everything you need to know about the manual, from where to find it to how to interpret its most complex sections.
The system ensures that no bilge water containing more than 15 parts per million (ppm) of oil is discharged into the ocean. Meeting the requirements of IMO Resolution MEPC
