SAUDI ARABIA - Mapping of pipelines


- used for mapping existing older pipelines  ...

is used for mapping existing older pipelines, particularly
 
where original maps may have been lost or are suspected of being inaccurate
if new construction work is being planned for the vicinity
to check that new pipelines have been installed within the legal ‘right of way’
to check on depth of cover, especially in conditions where erosion is thought likely
to identify the precise location of faults, branches, CP cross-bonds and anodes for repair or replacement with the minimum of excavation.
