any intervention on the joystick. It is the machine vision recognition software tied into the control and inertial navigation systems that allows it to perform those tasks consistently. This is still an emerging technology, and it takes a little time to dock autonomously. Finally, he notes that the telemetry, control systems, and communication links for ROVs have come a long way, too.Last, but certainly not least, McDonald points to the development of Oceaneering’s “Empowered ROV” – or E-ROV – as an indicator of its view on the future of subsea robotics. “E-ROV is

and field support campaigns in Asia and Australia.Pat Fournier, General Manager, Neptune, says, “Sonardyne came to see us in Perth late last year, as part of their Fusion 2 and 6+ launch tour. The in-water demos they ran were impressive to say the least - particularly the display of combined data telemetry and range updates and real-time INS-aided LBL SLAM (simultaneous localisation and mapping) calibration. This new Sonardyne equipment will continue to allow Neptune to remain at the forefront of technology and demonstrates Neptune’s commitment to supply its clients with the latest subsea technology

Searching for Shipwrecks

team assessed and prioritized these areas of interest in real-time during the project, adjusting which areas they were targeting as needed depending on weather and other factors. In addition to searching for shipwrecks, the expedition gave researchers and engineers the opportunity to test BEN’s telemetry range and refine its performance capabilities for future expeditions.Surveying in these waters can be challenging, but it can also be fruitful. In 2017, Thunder Bay National Marine Sanctuary, University of Delaware, and Michigan Technological University discovered and identified the wooden freighter

;Our system will be providing valuable integrity data and important real-time monitoring of the mooring system to enhance operational safety.”Stephen Auld, Global Business Manager, Subsea Asset Monitoring, Sonardyne, says, “Our SMARTs use fast burst and highly energy efficient acoustic telemetry, as well as ultra-low power electronics, reducing through-life costs for customers, and that was a real positive for SOFEC. For this project, we’ve also increased the time between battery replacement to in excess of six years, so it’s a long-life, easy to use system to ensure integrity

As a consequence, clients globally will benefit from a combined offering of technology for seismic data gathering, seabed deformation monitoring and tsunami detection, as well integrated acoustic positioning and telemetry for remote data access.At the heart of the cooperation is Güralp&rsquo

DOLPHIN: Enabling Technology for Acoustic Systems

Laboratory (OSL) have developed DOLPHIN - a patented method using analog cancellation that eliminates receiver saturation and enables simultaneous transmit and receive.  Figure 1 describes this concept.Figure 1: The basic concept of DOLPHIN. Image: QinetiQ North AmericaApplication to Underwater TelemetrySince the beginning of acoustic communications, the state of the art technology has been limited to half-duplex signals: transmit with the receiver off and then turn the transmitter off and receiver on and wait to receive, because the direct transmission at the source saturates the receiver electronics

However, the payload is flexible and it could also work within long baseline (LBL) arrays or with a USBL system where required, with a Sonardyne AvTrak 6, providing a transducer, transceiver and telemetry link in one”, says Ward.In 2017, the company performed demonstrations and trials and the HAUV was ready for commercial operations in 2018.  In one of the trial projects in 2017, the HAUV was launched from a quayside at a lake close to Saab’s Facility in Sweden to perform a &ldquo

today is that a really good pilot could do it quicker, but not necessarily consistently and repeatedly. The technology is evolving, but I expect that auto docking and intervention operations will become faster and more consistent in the near future, providing more efficient and reliable operations.The telemetry, control systems, and communication links for ROVs have come a long way as well. Faster communication and reliable telemetry, control systems, and software advancements have enabled us to get to where we are today and will help us get to where we’re going.Does Oceaneering develop its software
