Abstract
A subsea pipeline leak is located by: (1) introducing sonic energy into the line; (2) deploying an array of hydrophones in the vicinity of the line; (3) knowing the orientation of the array; processing the signals from the array so as to identify the location of the sonic anomaly at the pipe rupture created by the sonic energy introduced into the pipe.
