Oil & Gas (Pipeline)

Inspection of pipelines occurs both at time of their construction and while in service.

The US Office of Pipeline Safety (OPS) within the Department of Transportation (DOT) and Canada’s Natural Energy Board (NEB) prescribe requirements for testing of welds associated with the construction of new pipelines. Pipelines are inspected using radiography or ultrasonic methods.

In-service inspections associated with pipeline integrity programs include both in-line inspection and direct assessment. Direct assessment involves analysis of data from in-line inspections and other information, above ground inspection, selecting digs for visual and non-destructive inspections, and post assessments. 

Acuren provides pipeline owners with inspection and materials engineering services to support their construction, maintenance and integrity management programs. Inspection work is focused on identifying corrosion and cracking in pipelines. By deploying inspection crews from offices throughout the US and Canada, we can mobilize efficiently for construction weld inspection, station work, bridge inspection and verification digs within North America. Our materials engineering group performs failure analysis examinations and provides assistance in the development of weld procedures and integrity plans.

Acuren RoleProviding inspection for corrosion and cracking of the pipeline at direct assessment at sites identified by the client’s pipeline integrity program.

Services may follow in-line inspection tool runs, pressure tests, other direct assessment programs, or result from leaks/catastrophic failures.

Direct Assessment is a structured, multi-step evaluation, including excavation to examine and identify potential problem areas relating to internal corrosion (ICDA), external corrosion (ECDA), and stress corrosion cracking (SCCDA).
Methods UsedFor integrity work, we use MT, UT and VT to inspect pipeline dig ups and evaluate both the condition of the pipe and surrounding area, plus correlate the actual condition with the in-line inspection tool report data.
