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: 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.
