The Caspian Pipeline Consortium (CPC) has completed an inline inspection of two sections of the Tengiz-Novorossiysk oil pipeline. The sections inspected were 275 and 206 kilometers long.
To complete the project, three types of smart pigs were used. A multichannel geometry tool was used to check for faults in pipeline geometry (dents, corrugations, ovality) and verify bend radiuses. High-resolution magnetic inspection pigs were used to determine locations and assess the extent of defects oriented across the pipeline. Finally, ultrasonic inspection tools were used to look for such defects as corrosion, stratification, and scratch marks.
In early Q3 2017, CPC performed a similar inline inspection on a more than 250 km section of the Tengiz-Novorossiysk pipeline.
According to the consortium, a technical report and an industrial safety expert opinion will be prepared based on the inspection results, and any defects identified will be fixed as part of scheduled repairs.
