A detailed view of the pipeline and surrounding seabed Corrosion, anomalies, free spans, and anode depletion are among the conditions assessed during pipeline inspection.
How 3D Recon collects data 3D Recon combines three machine vision cameras with an inertial navigation system in a compact subsea housing rated to 4,000 meters. The offshore team connects 3D Recon to the ROV as a standalone sensor, with no external positioning solution required.
Positioning sensor data relative to subsea structures Many integrity management surveys, such as contactless cathodic protection, require positioning relative to the structure being surveyed.
Measuring chain-link wear without contact Zupt’s 3D Recon provides contactless mooring line inspection as a more efficient alternative to conventional “go, no-go” wear calipers and basic ROV video footage. How 3D Recon Inspects Mooring Lines Manipulated by an ROV, 3D Recon quickly models the mooring line or individual chain links at a pixel resolution of less than one millimeter.
Connecting inspection data across multiple passes Hull and tank inspections require overlapping swaths of survey data to be tied together.
Automated asset detection and identification subsea Zupt’s asset identification solutions use artificial intelligence to automatically detect and identify specific objects in practical subsea scenarios, reducing the need for additional offshore personnel. How the Software Identifies Objects Zupt develops and deploys software solutions using TensorFlow and YOLOv4 for object identification.
Detailed subsea models for inspection and measurement Assessing subsea assets requires detailed information about their condition and geometry.
Position and attitude monitoring during subsea installation Attaching expensive sensors directly to piles, conductors, and other subsea structures adds cost and risk to installation work.
