ABSTRACT:
Infrared scanning equipment and video cameras are used in an airborne survey of a pipeline while recordings are made of the information collected. Simultaneously, information is recorded to identify the locations of the collected information. The recorded IR tapes are then examined for portions containing temperatures which exceed established threshold temperatures. These extrathreshold temperature areas are then examined in the comparable visual tapes for reasons other than pipeline leaks to account for the anomalies. Other available information pertaining to the pipeline may also be referred to for posible explanations. Those areas for which analysis provides no explanation are then visited to repair leaks or find nonleak explanations. A record is made for future use which identifies all areas having explained anomalies in order to avoid the need for future repeat visits to these areas.
