Understanding the technique

Deploys an inspection platform through a pipeline to collect condition data along its route. Solutions are selected for piggable and non-piggable assets according to geometry and operating constraints.

Where it adds value

Transmission and process pipelines requiring internal condition assessment.

The purpose is to provide evidence that supports a defined asset decision: prioritizing maintenance, investigating degradation, assessing serviceability or documenting equipment condition. The examination is planned around the asset's operating context and the information needed by the owner.

Inspection outputs

Anomaly listings, location references and data for prioritizing verification and integrity assessment.

Planning considerations

Tool selection depends on pipe diameter, bends, valves, access and the defect types of interest. Relevant anomalies require assessment and, where needed, field verification.

From scope to decision

Review the asset

Provide equipment identification, drawings, material details, operating conditions and previous inspection records where available.

Agree the examination plan

Confirm the inspection objective, accessible locations, coverage, acceptance basis, site arrangements and reporting requirements.

Document and evaluate

Review recorded findings against the agreed scope, identify any coverage limitations and define the need for further inspection or engineering assessment.

Project questions

What information helps define a quotation?

Share the asset type, location, quantity, inspection objective and desired schedule. Drawings, previous reports and access information help the team prepare a realistic scope.

Can this technique be combined with other services?

Yes. Complementary examination or engineering assessment may be needed to characterize relevant findings. The combination depends on damage mechanisms, material, geometry and the decision required.
