Abstract: The dual submarine leak detection system provides for controllable in-pipe leak detection. The dual submarine leak detection system includes first and second submarines joined to one another by a tether. Each of the submarines includes a housing and at least one leak detector mounted thereon. A communication transceiver is mounted in the housing for remotely communicating the leak condition and a location of the leak condition, as well as receiving control and communication signals. Each submarine further includes at least one selectively retractable leg mounted on the housing and selectively extending therefrom, and a motor mounted within the housing for driving a propeller to propel the submarine through a fluid-filled pipe. A control system further allows for controllable or programmable steering of the submarine through the fluid-filled pipe and any pipe joints associated therewith.
