The Oil Discharge Monitoring Equipment (SMART ODME) is a slop water monitor for tankers.
The SMART ODME has been designed to provide means of monitoring, recording and controlling the ballast discharge for crude oil, product and chemical tankers including ICE class vessels.
This system is modular in construction and does not require the usual pump/motor bulkhead penetration as used on older systems.
The SMART ODME includes all components required to meet MEPC 108(49) and the latest MEPC 240(65) for bio fuels, effective 1 January 2016.

The SMART ODME incorporates a ‘simulation mode’ to aid system demonstration to PSC surveyors and is designed for ease of retrofitting, operation, installation and maintenance. Discharge limits are set at 30 litres of oil per nautical mile or 1/30,000 of the previous cargo for slop and wash water discharges.
Oil discharge monitoring
Oil discharge monitoring is a crucial component for efficient operation on board ships, ensuring compliance with the stringent MEPC.108(49) marine environmental regulations. These guidelines mandate the use of advanced Oil Discharge Monitoring and Control Systems on tankers. This oil discharge monitoring equipment is essential for tracking the oil content in slop water discharged into the sea.

By maintaining precise monitoring, ships can efficiently manage oil discharge, minimising environmental impact and adhering to international pollution standards.
The integration of these systems supports automatic data recording, which aids in regulatory audits and reporting processes. Furthermore, by preventing any discharge above regulated limits, these systems help avoid costly penalties, thus preserving the vessel’s operational integrity.
Efficient oil discharge monitoring not only safeguards marine ecosystems but also aligns with sustainable shipping practices, contributing to the overall operational efficiency and eco-friendliness of maritime activities.
