Inspection, Repair and Maintenance

Most subsea assets require periodic inspection for corrosion and cathode protection, leak detection, scour, depth of burial, out of straightness surveys (OOS) or general video inspection (GVI) to comply with statutory regulations. There are various external inspection techniques involving sensors such as multibeam, sonar, profilers, electromagnetic induction, photogrammetry and video cameras mounted on towed vehicles such as ROTV, DROV or conventional ROVs. Internal inspection of pipelines is often conducted using pigging equipment but there are other techniques for non destructive testing (NDT) such as ultrasonic thickness measurement, MPI and magnetic flux leakage.
