ABERDEEN, UK - OceanTools has released its laser-based optical 3D scanning system, C-Scan.
Encased within subsea housings and providing an operational depth rated at 3000 m (9,842 ft), the C-Scan system comprises a 360° rotary encoder plus a laser triangulation system capable of taking measurements 15 times per second and generating 700 discrete data points per scan. It has a range of up to 5 m (16 ft) and a resolution down to 0.5 mm.
Measurements are detected, analyzed, and processed by software, enabling the user to visualize the target object and take measurements of specific suspect anomalies within moments of the scan taking place.
Data generated by the system may also be exported to an external CAD package, where supplementary tools, such as the color contouring of heights and distances, may be rendered for additional analysis and reporting.
Already field tested on several projects, C-Scan performed inspection activities related to internal caisson integrity, external caisson clamp play and FPSO block bearing wear.
