About the course

This course enables learners to assess the acceptability of corrosion defects identified on their pipeline assets. Throughout the course, a range of defect assessment approaches will be explored, along with their capabilities and limitations. This course will enable learners to make informed decisions when performing defect assessments, or reviewing the work of others.
