Integrity management of subsea pipelines

About the course

Highly recommended for anyone involved in the maintenance and integrity of assets and pipelines, this course offers a thorough understanding of the engineering principles behind successful integrity management.

With case studies and worked examples, this course covers assessments to DNVGL-RP-F105. This course also includes a site visit to a manufacturer. You will have the opportunity to see subsea inspection tools and advanced inspection techniques being demonstrated on pipe samples, reinforcing what you have learned.

*Integrity management courses held in Aberdeen also include a site visit to a manufacturer.
