SL1 LiDAR Laser

The World’s First Underwater Commercial LiDAR System Designed for Offshore Oil and Gas

The 3D at Depth SL1 sensor was designed to address the needs of the subsea construction, survey, and inspection industry in terms of range, accuracy, field of view, depth, and integration. The result is a system that integrates a unique optical design, a custom high sensitivity receiver, a sub-nanosecond pulsed high peak power solid state laser, high speed electronics, and patented processing methods to provide the accuracy and ranges required for subsea measurement tasks.

The SL1 has an embedded MEMS motion sensor to calibrate pitch and roll and create real world reference frames.  This overcomes the inability to “level” a subsea sensor.  The system also comes with an onboard computing subsystem and 750GB internal hard drive as well as a 64GB internal solid state drive for fast performance and flexibility.

For real time data QC and data preprocessing, the system includes a computer with 3D at Depth software for collection (3D Collect), viewing (QuickView) and the creation of LAS and 3DC files (3D Cloud).  3DC is a proprietary compression format which allows operators to move data across low bandwidth networks – from vessels to on shore processing teams. An integrated rotational stage provides a 30 degree x 360 degree field of view while mounted on an ROV or tripod. A graphical operator interface provides real time quick views of the results and exports to industry standard point cloud formats instantly. With the SL1, you can significantly reduce the time for standard tasks such as spool piece metrology and other subsea construction survey tasks while dramatically improving data quality

Fast, highly accurate 3D data collection for field surveys, as-builts and metrologies. Each system easily integrates and can be deployed via tripod, ROVs or AUVs, surface vessels and divers systems. The rugged design supports a variety of subsea workflows and environments at depths up to 3000m.
