Inlet station

  • Is above ground section of pipeline in good condition and free of corrosion?

  • Is the area around the inlet station in a clean and safe condition?

  • Are markers and signs in good condition, visible and correct and are adequate to remain in situ until next inspection?

  • Are all pipe supports for above ground portion providing adequate support and free of corrosion?

  • Is anti-corrosion coating at ground interface in good condition and free of signs of damage or deterioration?

Route surveillance

  • Is surface in good condition and free of any evidence of variation to surface conditions? E.g. Erosion or earth movement along route.

  • Is route free of any indication of leaks? E.g. Dead vegetation

  • Is route unchanged? E.g. is there any evidence of construction activity or impending construction activity on or near the route?

  • Is rout accessible? E.g. Are there any impediments to access of the route, valve station, pressure regulator stations, compressor stations, pump stations, catholic protection sites, communication installations, and the like?

  • Are markers and signs in good condition, visible and correct and are adequate to remain in situ until next inspection?

  • Does route appear secure? E.g. Is there any evidence of unauthorized entry?

  • Is vegetation being adequately managed along route? (vegetation shall be restricted to allow free passage along the pipeline route and vegetation who's roots may damage the anti corrosion coating of the pipeline shall not be permitted in the vicinity of the pipeline.)

Metering station

  • Is area around the station clean and in safe condition?

  • Are fences and gate maintained in good condition to ensure the protection of the public?

  • Are markers and signs in good condition, visible and correct and are adequate to remain in situ until next inspection?

Additional items

  • Have all outstanding actions identified in previous inspections or assessments been closed out?

  • Is the risk assessment for the pipeline still valid? E.g. Are there any factors that may change the risk assessment for the pipeline such as urban encroachment or new developments?
