OIL DISCHARGE MONITORING CONTROL SYSTEM
The Oil Discharge Monitoring Control System (ODME) is a key part of marine environmental protection. It helps ships monitor and manage oily water discharge to meet international regulations like MARPOL Annex I. This system checks oil content in water before discharge and ensures only clean or permitted levels go overboard.
The ODME system includes several main parts. These are a sampling unit, oil content meter, flow meter, data recorder, control unit, and overboard valve. All components work together to measure oil content, flow rate, and discharge location using GPS.
When operating, the system automatically records every discharge event. It keeps track of oil levels, time, date, ship speed, and position. This data is saved and used to prove compliance during inspections.
In tankers and large vessels, ODME is a legal requirement. It prevents accidental or illegal discharges of oily water into the sea. New systems offer digital displays, touch screens, alarms, and even remote monitoring options.
Modern ODME units are compact, reliable, and easy to maintain. They are installed in the engine room or near the oily water separator. Some popular models include brands like PSM, Rivertrace, or Jowa, each offering high-accuracy monitoring and automatic record-keeping.
Regular testing, calibration, and crew training ensure the system works correctly. With proper use, ODME systems protect marine life and help vessels avoid heavy fines or detentions.
FAQs
1. What does ODME stand for?
Oil Discharge Monitoring Equipment.
2. Why is ODME important?
It helps ships follow environmental laws by tracking oil discharge.
3. Is ODME mandatory on all ships?
It is required for oil tankers above 150 GT and other ships above 400 GT.
4. What data does ODME record?
It logs oil content, date, time, ship location, and discharge volume.
5. Where is ODME installed?
Usually in the engine room or near the oily water separator.
6. How does ODME detect oil?
It uses an oil content meter that measures parts per million (ppm).
7. What is the maximum allowed oil discharge?
Usually, it must not exceed 15 ppm.
8. Can ODME records be used in audits?
Yes, they provide proof of legal operation.
9. How often should ODME be calibrated?
At least once a year or as per manufacturer guidelines.
10. What happens if ODME fails?
Manual discharge is not allowed; repairs must be made before discharging.
