Doppler Velocity Log (DVL) technology from Sonardyne Inc., Houston, has been selected to help navigate Canada’s flagship undersea research vehicle, ROPOS. The order for a 4000 metre depth rated, 600 kHz Syrinx DVL was placed by the Canadian Scientific Submersible Facility (CSSF), the not-for-profit corporation who operate ROPOS, following a trial to evaluate its capabilities. This concluded that Syrinx was able to maintain, and regain bottom lock over a wide range of altitudes and seafloor terrains including soft fine sediment and rugged steep slopes close to hydrothermal vents.
Vincent Auger, IT and Navigation Manager at CSSF said: “Our first dive with Syrinx installed on ROPOS was on an active hydrothermal vent site in the Indian Ocean. The bottom there is very rugged; essentially as rugged as it gets, but Syrinx coped with the challenge very well and demonstrated reliable bottom lock throughout the mission.”
Kim Swords, Senior Application Engineer with Sonardyne in Houston added: “We’re delighted that CSSF is the latest scientific organisation to recognise the ownership benefits offered by our new Syrinx. It takes away the need for DVLs of different operating frequencies, it is deeper rated than its rivals and it has lower servicing costs thanks to innovations such as individually replaceable transducer capsules. And given the strength of international currencies against Sterling at the moment, our UK-manufactured Syrinx represents excellent value for money.”
