Pathfinder Foam Caliper Proving

The Pathfinder® Foam Caliper Tool is a pipeline inspection device with a high level of mechanical compliance,

which is capable of negotiating severe restrictions in a pipeline with minimal risk of blockage or damage.

Pathfinder has been developed for the first stage assessment of operational pipelines prior to the use of metal-bodied pigs.

It can be used in conjunction with standard foam cleaning pigs to prove the bore of pipelines with unknown internal conditions, including: 

• New and operational pipelines which have not previously been pigged
• Operational pipelines which have suffered damage due to external interference but are inaccessible for external inspection
• Operational pipelines with unknown levels and distributions of wax or scale deposits. 

Information from the tool is used to identify the location and the size of localised bore restrictions in the line, allowing informed decisions to be made on the appropriate types and configurations of pigs to be deployed to clean or gauge the line. 

AOGV Technoloy - Mechanical Isolation Tool

The AOGV Mechanical Isolation Tool can insert and remove an isolation spade/skillet on any live flange pair to create a zero-energy zone where inspection, modification and maintenance work can be performed safely and efficiently whilst production is maintained.

 Value and Applications of the AOGV  

• Change out gaskets
• Reduction in TAR / Maintenance Schedule
• Tie-ins of new plant modules
• Decommissioning / Spool replacement
• Valve replacement or repair
• Allow process flow and cashflow, to continue.
• Execute work outside of a turnaround, increasing asset uptime.
• Positive isolation- vessel entry
• No requirement for “hot work”
• No permanent modifications to plant/piping
