Abstract

An oil leakage detector for detecting the leakage of e.g. diesel or fuel oil in an engine room of a vessel comprises a conduit (102) for an airflow therethrough, and a screen (108) in the conduit. The screen (108) is meshed to prevent oil particles or droplets from passing therethrough. A sensor (110) determines a pressure loss across the screen, and a control system (114) operatively connected to the sensor is configured to output an oil leakage warning signal if the pressure loss exceeds a predetermined threshold value. A fan (104) may be provided for generating the airflow through the conduit. A gas sensor (112) for determining the presence of hydrocarbon, carbon monoxide or carbon dioxide is optionally provided.
