Sonomatic and sister company Geo Oceans planned and executed a complex Mini-ROV advanced NDT scope on riser turret mooring J-tubes. The scope included high-pressure water cleaning of 20-year-old marine growth, CVI inspection, advanced NDT ACFM inspection of welds, and circumferential C-scan corrosion mapping of the J-tubes, all within the splash zone.
Bespoke ACFM actuator and ROV attachment systems were engineered, tested, and demonstrated in Geo Oceans’ R&D test tank facility and in a 3D computer model prior to mobilisation offshore.
