Is your pipeline ready for ILI?
What happened
Pipe Tek explains that accurate inline inspection depends on thorough pipeline preparation and that inadequate cleaning commonly leads to reruns and delays. The article highlights pigging debris volumes and required tool speed windows as concrete readiness checks; insist on pigging logs and debris metrics before tool mobilisation
Buyer takeaway
Require pigging reports, debris thresholds and speed‑window confirmation as pre‑mobilisation deliverables to reduce rerun risk
Cost / money
Directional: insufficient cleaning directly increases contractor days and rework budgets due to reruns
Supplier / commercial
Inspectors may push staged acceptance and shorten quote validity if demand for tools rises; capture readiness as a contractual gating item
Safety / operations
Incomplete cleaning increases onsite handling tasks and confined‑space exposure; require safe cleaning methods and certification
What to watch
Watch pigging return logs and insist on defined speed windows and debris thresholds in the SOW; absence is a red flag for reruns
Key facts
- Pigging debris volume is the primary field indicator of readiness
- Inspection tools must operate within defined speed ranges to collect accurate data
- Poor prep commonly forces re‑cleans and reruns

These conditions not only increase operational risk but can also affect tool performance and data resolution
“Consistent speed during preparation runs is one of the strongest indicators of inspection readiness. ” Pressure fluctuations during pigging are often a result of partial blockages or debris in front of the tool
“If cleaning pigs can’t travel smoothly, an ILI tool is unlikely to perform optimally,” said Brannelly. “Consistent speed during preparation runs is one of the strongest indicators of inspection readiness
