By integrating these values, the ODME's computer unit calculates the amount of oil being discharged per nautical mile. If the IRD exceeds , or if other MARPOL criteria are not met, the system automatically triggers an alarm and operates a series of valves to stop the overboard discharge. Key Components and Operation

According to , any oil tanker of 150 gross tonnage and above must be fitted with an ODME to ensure that the discharge of oil does not exceed regulatory limits (typically 15 parts per million for machinery space bilges, and specific flow rates for cargo tank washings). odme working principle

A tanker is deballasting in a special area. ODME reads 12 ppm, flow = 150 m³/h, speed = 12 knots. Instantaneous oil discharge = (12 × 150) / 12 = 150 liters/nm → alarm triggers, valve closes automatically, discharge stops until speed increases or flow reduces. By integrating these values, the ODME's computer unit

The ODME is not just a single sensor; it is a complex integrated system. The working process involves four distinct stages: A tanker is deballasting in a special area

Based on these inputs, the computer calculates the Instantaneous Rate of Discharge (IRD) in liters per nautical mile. If the IRD exceeds permitted limits, the system automatically closes the overboard discharge valve and redirects the oily water back to the slop tank. 2. Key Components
