Digital X-Ray Camera DXr1

Global Marine present the first digital submarine cable X-ray Camera, DXr1, developed in conjunction with leading UK Radiography company, JME. This state-ofthe-art camera will supersede the Type 13 cameras and eliminate film technology & wet chemical processing. The light bulb x-ray illustrates the clarity, detail & flexibility of radiographs obtained from the DXr1 camera.

Digital X-Ray and Assessment Development for Subsea Cable Jointing

The DXr1 is the successor to the Type 13 Mk III X-Ray Camera for submarine cable use and has the same rugged marine construction and radiation safety. As the camera is fully digital, system repair time is reduced by eliminating the film processing stage and allowing image assessment to commence as soon as the first image is available. The digital images can be stored in a dedicated folder on the vessel server and therefore immediately available for the assessor to assess them with special software, incorporating a range of drop-down tools such as wall-thickness and inclusion gauges. Image defects can be marked-up and stored together with comments. When all images have been assessed, a summary sheet is produced giving an overall result for the joint. The advanced software contains noise reduction features, brightness/contrast adjustment and identifies 16,000 levels of greyscale.
