Underwater Laser Based Measurement
Interest and applications are growing for laser-based underwater measurements systems that can provide sub-millimetre accuracy. UVS partner, OceanTools, has completed a number of Offshore Oil& Gas tasks measuring cracks, gaps and corrosion on FPSOs and caissons. New applications may include mounting multiple systems onto a crawler.
OceanTools products include:
• C-Gauge: Measurement of cracks, gaps, lengths, diameters, radii and angles
• C-Profiler: Alternative to mechanical acoustic profilers for cross-sectional profiles, free- span measurement and structural deformation
• C-Scan: Internal rotational scanning of caissons, pipelines etc. External scanning of anchor chains and anodes.
• C-Gauge: Measurement of cracks, gaps, lengths, diameters, radii and angles
• C-Profiler: Alternative to mechanical acoustic profilers for cross-sectional profiles, free- span measurement and structural deformation
• C-Scan: Internal rotational scanning of caissons, pipelines etc. External scanning of anchor chains and anodes.
The laser has a very low power consumption and draws just 250mA at 24VDC. Because the power of the laser is below 70mW they are classed as ‘Laser class III-a’ meaning no special training is required to operate them.
