DECKMA OMD-2008 EV FC MCU

Overview

DECKMA OMD-2008 EV FC MCU | 15ppm Bilge Alarm with Flow Control & Manual Cleaning Unit

The DECKMA OMD-2008 EV FC MCU is an advanced version of the OMD-2008 15ppm Bilge Alarm, designed for continuous monitoring of oil content in treated bilge water discharged from approved oily water separator systems. It incorporates an Electric Valve (EV), Flow Control (FC), and a Manual Cleaning Unit (MCU) to improve operational reliability, simplify maintenance, and help prevent unlawful overboard discharge caused by insufficient sample flow. The system supports compliance with MARPOL Annex I and IMO Resolution MEPC.107(49) for marine pollution prevention.

At Ship Care Service, we supply genuine DECKMA OMD-2008 EV FC MCU systems, measuring cells, flow sensors, electric valves, spare parts, accessories, calibration support, and technical assistance for commercial vessels, offshore platforms, shipyards, and marine engineering companies worldwide.

What is the DECKMA OMD-2008 EV FC MCU?

The DECKMA OMD-2008 EV FC MCU is a marine 15ppm Bilge Alarm Unit installed downstream of an approved oily water separator. In addition to continuous oil content monitoring, this model includes three enhanced functions:

• EV (Electric Valve) – Automatically controls the clean water flushing process.

• FC (Flow Control) – Monitors sample flow and places the instrument into alarm if adequate sample flow is not maintained.

• MCU (Manual Cleaning Unit) – Allows the measuring tube to be cleaned quickly without opening the measuring cell, reducing maintenance time.

These features help improve system reliability while reducing the possibility of incorrect measurements caused by interrupted or insufficient sample flow.

Why a Bilge Alarm with Flow Control is Important

Accurate oil content measurement depends on maintaining a continuous representative sample through the measuring cell.

The integrated Flow Control (FC) system continuously checks the sample flow. If flow becomes too low or stops completely, the instrument generates a "Flow?" status alarm, preventing operation with an invalid sample and reducing the risk of accidental non-compliant discharge.

This provides additional protection for:

• Environmental compliance

• Safe vessel operation

• Accurate oil content monitoring

• Port State Control inspections

• Oily water separator performance verification

How the DECKMA OMD-2008 EV FC MCU Works

The system continuously monitors treated bilge water during oily water separator operation.

Step 1 – Bilge Water Sampling

A representative sample of treated bilge water flows through the optical measuring cell.

Step 2 – Optical Oil Content Measurement

The measuring cell continuously measures oil concentration using DECKMA's optical sensing technology, providing real-time monitoring of treated bilge water.

Step 3 – Flow Control Monitoring

The integrated flow sensor continuously monitors sample flow through the measuring cell.

If sufficient sample flow is not maintained, the system automatically enters alarm status and displays a Flow warning, helping ensure only valid measurements are used.

Step 4 – Alarm & Automatic Discharge Protection

When oil concentration exceeds the configured alarm value or an insufficient sample flow condition is detected, the system can:

• Activate visual alarms

• Activate audible alarms

• Operate the Automatic Stopping Device (ASD)

• Stop or divert overboard discharge

• Record alarm events for future inspection

DECKMA OMD-2008 EV FC MCU – Technical Information, Operation, Maintenance & Troubleshooting

Technical Overview

The DECKMA OMD-2008 EV FC MCU is an advanced 15ppm Bilge Alarm Unit designed for continuous monitoring of oil concentration in treated bilge water discharged from approved oily water separator systems. This model combines the proven OMD-2008 oil content monitoring system with three additional functions: Electric Valve (EV), Flow Control (FC), and a Manual Cleaning Unit (MCU) to improve operational reliability, simplify maintenance, and enhance measurement accuracy.

Installed downstream of the oily water separator, the system continuously measures oil concentration before overboard discharge. The integrated Flow Control verifies that a sufficient sample flow is maintained, while the Electric Valve manages flushing operations and the Manual Cleaning Unit allows quick cleaning of the measuring tube without dismantling the measuring cell.
