The JME portable X-Ray Betatron 7.5MeV is designed to produce high energy ionising radiation for industrial radiographic non-destructive testing. It can penetrate 30 centimeters of steel or 1 metre of concrete. Case study provided by JME Advanced Inspection Systems.
PROJECT OVERVIEW
In January 2016, a client approached Oceaneering for a nondestructive testing (NDT) method that would be suitable for use on two risers in the North Sea. Each of the risers had significant external corrosion scale, also known as scabs – prompting the need for verification of the risers’ integrity. The goal was to extend the production timeline for the main oil line (MOL), which has a 24inch outside diameter (OD), and the gas producer, with a 20inch OD. The client required another year’s service from the risers in order to align the completion of its necessary repairs with the next planned turnaround.
