Leak detection system and method for offshore hose lines

摘要

An oil leak detection device and system (10) is installed in a double carcass hose (16, 18) in communication with a collection space (94) between inner (86) and outer carcass layers (88) of the hose (16, 18). The oil leak detection device (10) communicates information relating to the presence or absence of fluid within the collection space (94) to a remote location (14). The leak detection device (10) is positioned within a chamber (74) within a hose nipple (56). The chamber (74) communicates with the collection space (94) and collects oil leaking through the inner carcass (86) into the collection space (94) between the inner and outer carcass layers (86, 88). The oil leak detection device (10) is preferably an electro-optic sensor (34) having optical detection means for detecting the presence and absence of fluid in the collection chamber (74), and communication means for transmitting information regarding the detected fluid status to a remote display unit (14). The display unit (14) may include visual and/or audible indicia identifying the status and location of a plurality of sensors (34) and thereby identify the location of a specific leak. <IMAGE>
