Abstract: A fluid leak detector is provided for a double carcass hose line segment and includes a sensor housing defined by sidewalls externally mounted to the hose line segment and having an internal housing chamber in communication with the collection space. An optical sensor is mounted through at least one sensor housing sidewall and positions an optical sensing element means within the sensor housing chamber for detecting a presence of fluid in the hose collection space. The optical sensor further includes analysis element means connecting to the optical sensing element means and positioned outside of the sensor housing one, wall, the analysis means generating data indicative of the fluid status within the hose collection space; and transmitter element means connecting to the analysis means for receiving data from the analysis element means and transmitting the data to at least one remote receiver.

Abstract: The present invention is directed to a method of making a flexible hose, comprising the steps of extruding a first poly(vinyl chloride) compound to form a tube, the tube having an inner cylindrical cavity coextensive with the tube; a) applying a textile reinforcement over the tube; b) extruding a second poly(vinyl chloride) compound over the textile reinforcement to form a cover layer, said tube, reinforcement and cover defining a hose composite; c) inserting a rigid mandrel into the inner cylindrical cavity; d) wrapping a fabric wrap around the outside of the cover of the hose composite; and e) processing the wrapped hose composite at a temperature in a range of 130 to 160° C. and a pressure of 30 to 70 psig for a time ranging from 5 to 40 minutes.

Abstract: A flexible seawater suction hose is configured to include a tube body of flexible rubber material reinforced by textile fabric and steel wire. Opposite ends of the tube body are terminated to a respective connector. A steel cable is incorporated within the tube body and extends longitudinally between the opposite tube body ends and attaches to the opposite end connectors. The flexible hose connects at one end to a rigid conduit by means of one connector and extends downward therefrom to a prescribed depth to facilitate extraction of seawater at a desired temperature.

Abstract: An oil leak detection device and system is installed in a double carcass hose in communication with a collection space between inner and outer carcass layers of the hose. The oil leak detection device communicates information relating to the presence or absence of fluid within the collection space to a remote location. The leak detection device is positioned within a chamber within the hose nipple. The chamber communicates with the collection space and collects oil leaking through the inner carcass into the collection space between the inner and outer carcass layers. The oil leak detection device is preferably an electro-optic sensor having optical detection means for detecting the presence and absence of fluid in the collection chamber, and communication means for transmitting information regarding the detected fluid status to a remote display unit.
