• Q: What types of pipelines are considered “unpiggable” or difficult to inspect, and how does Quest Integrity address these challenges?

A: Pipelines are considered “unpiggable” when their design or operating conditions prevent the use of conventional inline inspection (ILI) tools. Common challenges include complex geometries and physical constraints, such as non-barred tee connections (including hot taps), wyes or modified systems, significant internal diameter changes, tight-radius bends, partially closed valves, and the absence of launch or receive facilities. Low-flow or low-pressure conditions, as well as small-diameter or specialty lines like subsea spools and loading lines, can also limit inspection options.

Quest Integrity addresses these challenges with advanced inspection technologies and specialized access solutions designed for difficult environments. Our tools are engineered to navigate complex pipeline geometries, operate effectively in low-flow conditions, and inspect assets that cannot accommodate traditional ILI systems. For offshore applications, the InVista® Subsea Launch/Receive system enables inspection without the need for topside pigging facilities, making it possible to assess deepwater and remote pipelines that were previously inaccessible.

The result is reliable, high-quality inspection data that empowers operators to make informed integrity decisions across even the most challenging pipeline assets.

• Q: Why is pipeline inspection necessary?

A: Pipeline inspection is essential for ensuring the safe, reliable, and efficient operation of energy and process infrastructure. Over time, pipelines can develop corrosion, deformation, cracking, and other integrity threats that are not visible externally. Regular inspections allow operators to detect these issues early, helping to prevent unplanned shutdowns and reduce the risk of leaks or failures.

By delivering accurate, actionable condition data, inspection supports regulatory compliance, extends asset life, and enables more informed maintenance and investment decisions. The result is improved safety, reduced operational risk, and optimized performance across the entire pipeline system.
