Abstract: L28.00002 : Doing More with Less – Advanced Sensing enabling uROV, a Next Generation Inspection, Maintenance, and Repair Platform for Subsea Assets
IMR service providers currently utilize remotely operated vehicles (ROV) tethered to a surface vessel and piloted in real-time. Recent progress in underwater perception, maritime autonomy, and artificial intelligence can disrupt this old method and allow developing a leaner service model that significantly reduces the costly vessel and personnel support while improving data quality. uROV (untethered ROV) is unique in its approach to this problem. Around producing subsea fields, a higher level of supervision than “launch and forget” is needed. Thus, the uROV platform is based around supervised autonomy wherein a “person in the loop” has real-time feedback from onboard sensors and is then able to update the operation.
This talk will present the novel sensor architecture embedded on the uROV platform to enable this vision. Results include a first demonstration of remote acoustic visualization and control of subsea LiDAR during a high-resolution scan of a P-38 wreck. Extensions under development will enable remote mapping of infrastructure surface temperatures as well as detection and localization of potential hydrocarbon leaks. I will lastly present progress towards utilizing the data generated by these sensors for localization and cluttered environment navigation to safely approach high value assets.
