Untethered Vehicle Tech Continues to Advance Autonomy

is pioneering a networked systems approach for ocean data collection. Their approach aims to extend mission duration with high power payload capacity while limiting offshore personnel through autonomous data collection and quality assurance. They also aim to reduce staffing onshore with autonomous data processing. A key in this vision is efficiency with scale of operations and reliability from many interchangeable vehicles, which they term AxVs.The Terradepth Concept of Operations (CONOPS) includes: 1) surface and subsurface capability, 2) two or more identical vehicles, 3) launch from shore or

principles,” says Ecotone CEO, Oddbjoern Roedsten, adding that tweaks to the equipment to 2016 have led to today’s first commercial uses. “There has been development on the data analysis side with a higher degree of automation to cut down on the time and work involved in data processing and analysis, and it allows us to deliver an effective and accurate service for mapping and inspection.”Vital speedWhile pipeline inspection continues to see the introduction of new UAVs and ROVs that move down the survey track faster, they’re nothing without their sensors.

New AI Tool for Sonar Noise Cleanup

focus more time on other important aspects of the survey and processing workflow.This new approach to clean sonar noise is powered by the CARIS Mira AI engine, a new cloud-based platform to host current and future AI solutions. CARIS Mira AI also provides a flexible package capable of scaling with data processing needs. All data directed to the CARIS Mira AI platform is anonymized, randomized and encrypted before transmission. For additional security, no data remains stored on the cloud following the AI classification process.“By leveraging deep learning techniques, Teledyne CARIS is poised to

ADCPs & DVLs: Recent Tech Developments

of operations and decrease the cost of current measurements they recently introduced the ECO platform. ECO, Nortek’s mini-ADCP for shallow water profiling was announced for sale in late 2019. It features a handheld, wirelessly charged 1MHz ADCP, programmed with a smartphone app.  Data processing and quality assurance is provided through an automatic cloud-based service. In addition to these adaptations for the instrument itself Nortek took the development one step further and designed a compact buoy and timed-release system to simplify deployment in shallow waters.ADCPs and DVLs are

data that’s then processed to show where fish are.  And the results have been good, says Malik, avoiding issues fishing vessels can have with vessel noise in the water because it’s able to dip the sonar further away from the vessel. The next step is edge analytics – i.e. data processing on the drone so fisherman know faster where fish are.But, Birdview see other opportunities, including dipping a modem to gather data from underwater sensors or even to provide a communications link to remote control ROVs or mobile underwater platforms, so they don’t have to stay within
