Oil Discharge Monitoring Equipment (ODME)

Oil Discharge Monitoring Equipment (ODME) is an essential system used on tankers to regulate and control oil discharge in compliance with MARPOL Annex I regulations. The ODME system continuously monitors the oil content in ballast or slop water, ensuring that discharges meet permissible limits before being released overboard.

What is Oil Discharge Monitoring Equipment (ODME)?

Oil Discharge Monitoring Equipment (ODME) is a device used to measure and monitor the discharge of oily water from ships. The oil discharge monitoring system is crucial for ensuring that oily water discharge, particularly from oil tankers, stays within permissible limits to prevent marine pollution. After discharging crude oil at a port, oil tankers often take in ballast water for stability. Before loading new cargo, this ballast water must be discharged, and ODME ensures operation in oil tankers.

How does ODME Work?

ODME manages the discharge process through two valves: the slop valve and the overboard valve, which operate in opposite states—when one is open, the other is closed, and they never operate simultaneously. To calculate the Instantaneous Rate of Discharge, ODME uses three key parameters: the oil content in parts per million (PPM), the flow rate in cubic meters, and the ship’s speed in knots. These values are displayed in the cargo control room. If the discharge rate of oil content remains below 30 liters per nautical mile and the total amount discharged does not exceed 1/30,000 of the total cargo quantity, the overboard valve opens to allow discharge. If these conditions are not met, the overboard valve closes, and the slop valve opens, ensuring compliance with MARPOL Annex 1 regulations.

What are the MARPOL Regulations Regarding ODME?

MARPOL Annex 1 mandates that oil tankers with a gross tonnage of 150 tons or more must be equipped with an ODME system approved by the relevant administration. This oil discharge monitor must include a recording device that provides a continuous record of the discharge rate in liters per nautical mile, the total quantity discharged, or the oil content and discharge rate. These records must be time-stamped, dated, and retained for at least three years. Additionally, a proper oil record book must be maintained to document all oil discharge activities.

Routine Maintenance and Inspections

Regular maintenance and inspections of your ODME system are crucial. Swift Marine Tech Services Pte Ltd offers comprehensive maintenance and inspection services to identify any issues that could affect the system’s performance, replace faulty components such as the oil content meter, oil discharge monitor, or flow meter, and ensure that the Oil Discharge Monitoring System consistently meets regulatory standards. These efforts help minimize system malfunctions, reduce downtime, and ensure compliance with the latest regulations, including MEPC resolutions and MARPOL Annex 1. Keeping the appropriate spare parts on hand is essential to minimize potential downtime during maintenance.

Installation and Commissioning

Swift Marine Tech Services Pte Ltd provides professional installation and commissioning services for your ODME system, ensuring it meets industry regulations and vessel specifications. We are equipped to install and commission various brands of Oil Discharge Monitoring and Control Systems, including Rivertrace. Our expert team ensures your system operates optimally and delivers accurate readings. Additionally, we offer remote support to address any challenges during installation or commissioning. For new tankers, meeting these installation requirements is essential for obtaining their initial certification.

Repairs and Upgrades

Swift Marine Tech Services Pte Ltd offers expert support for repairs and upgrades of your ODME system. We provide prompt, optimal solutions for any ODME brand, including the integration of Rivertrace systems. Our team uses genuine manufacturer spare parts and follows best practices to extend your system’s lifespan and ensure compliance with relevant regulations. We also maintain a stock of spare parts for various ODME systems to minimize downtime during repairs. For older tankers, upgrades may be necessary to meet current MEPC resolutions and other international standards.

Calibration and Testing

To maintain the precise operation of your Oil Discharge Monitoring Equipment system, Swift Marine Tech Services Pte Ltd conducts annual calibrations. Our certified technicians rigorously test various ODME brands to verify accuracy and alignment with regulatory standards. After successful calibration, a calibration certificate is issued, confirming your vessel’s compliance with oil discharge monitoring requirements. Regular testing also ensures the continued accuracy of the bulk oil tank monitoring system and measurements during ballast water discharge.
