Hydrophone equipment recovery off Oregon coast performed with microROVThe situation facing scientist Joe Haxel of Oregon State University's Hatfield Marine Science Center was grim. His unique hydrophone array - with its irreplaceable data - was 175 feet (53 meters) deep, six miles offshore. Its acoustic release mechanism which should have released a buoy had responded to its commands, but the buoy was nowhere to be seen. Something had gone wrong. The Northwest Marine Renewable Energy Center was counting on the data that had been collected over several months for a study of environmental impacts at the site.


Investigation by human divers at that depth was possible - but expensive and dangerous. Joe contacted the team of Water Works Resources, LLC (WWR) and Submerged Recovery & Inspection Services (SRIS) for a better solution. Using two VideoRay LLC VideoRay Pro ROVs, the equipment was recovered in less than five hours, including two hours transiting to and from the site in Oregon State University's research vessel Elakha.

Commenting on the recovery by Dennis Lancaster of WWR and Craig Thorngren of SRIS , Mr. Haxel said: "I had doubts going in, but your confidence and proven capability made a quick believer out of me. You guys delivered BIG TIME! I would not hesitate to recommend your services to any of my colleagues". Speaking for SRIS, Craig responded "I've used the techniques we deployed here several times, and taught them in several of my ROV piloting classes. I was fairly confident of our success." Thorngren and Lancaster also attributed their success to their VideoRay ROVs. "Having the most robust and reliable gear on the market today makes all the difference. Time and time again, my VideoRay has performed brilliantly. I have never had to scrub a mission because of the VideoRay."
