The client reached out to PFS to plan and conduct an ILI assessment of an out of service liquid pipeline system, aiming to assess its condition before initiating any restoration efforts following seven years of inactivity.

Scope of Work

Our pipeline pigging Subject Matter Expert (SME) consulted with the client on-site to survey the work areas, pinpoint any obstacles, and worked together, along with the inspection tool vendors, to devise the execution plan for the successful pipeline inspection.

The approach entailed deploying an initial foam disc pig to confirm the line's pigging capability and evaluate the pipeline's cleanliness to determine if additional cleaning was necessary. Subsequently, a gauge pig and two distinct smart tool runs were propelled through the pipeline.

  • The pig launcher was positioned on the premises of another significant fuel terminal owner, requiring simultaneous operations while complying with their specific access protocols.
  • The pig receiver was located within one of the busiest fuel terminals in North America, requiring simultaneous operations amidst a significant volume of tanker truck activity during the scheduled inspection.
  • The uncertainty lingered regarding whether the mainline slab gate valves could hold the nitrogen gas pressures necessary for launching and receiving the two tool runs.
  • Ensuring communication among the client, two construction contractor companies, two ILI tool vendors, the pig tracking vendor, our nitrogen pumping supervisor at the injection site, and our project manager stationed at the receiver, who led the communication.

PFS can help with all aspects of pigging. Keep reading to learn more about the pigging products and services we offer.
