Abstract
This paper presents the successful deployment of advanced eddy current array (ECA) probes for the inspection of intergranular stress corrosion cracking (IGSCC) present on the external surface of aboveground in-situ pipelines. During an inspection campaign carried out in 2020 and 2021 mainly on emulsion and produced gas pipelines, more than 20 indications were found over 20 kilometers of pipeline. These indications range from 5 mm to 400 mm long by 1 mm to 12 mm deep. The technology provided the pipeline operator a fast method for IGSCC detection leading to cost-effective inspection and maintenance planning, while preventing the risk of loss of product containment.
