PIPELINE DEPTH OF COVER DETERMINATION METHOD AND APPARATUS

A method for determining depth of a conduit below a ground surface includes moving an inline tool along and within the conduit and collecting pipeline elevation data of the conduit. The method also includes placing a plurality of aircraft targets on the ground surface above the conduit and collectin...

Beschreibung
Zusammenfassung:	A method for determining depth of a conduit below a ground surface includes moving an inline tool along and within the conduit and collecting pipeline elevation data of the conduit. The method also includes placing a plurality of aircraft targets on the ground surface above the conduit and collecting, by an aircraft, surface data of the ground surface. The method includes receiving, at a controller, survey data of the ground surface. The method includes determining, based on the surface data and the survey data, an ellipsoidal height of the ground surface and determining a depth of cover of the conduit based on the ellipsoidal height and the pipeline elevation data.
