ROPOS (Remotely Operated Vehicle for Ocean Sciences) is a modular Work-class ROV which can be reconfigured to operate at different depths and from different size vessels depending on the science mission. In the setup Syrinx has been chosen to support, ROPOS is a free-flying 4,000 meter rated vehicle equipped with HD cameras, powerful lighting and a comprehensive suite of environmental probes, sampling skids and sensors.
Sonardyne’s Syrinx differs from other DVLs through its use of fully linear signal processing, low noise electronics and adaptive bottom lock. These features enable Syrinx to operate at altitudes up to 50 percent higher than conventional 600 kHz DVLs with the high resolution performance of a 1200 kHz DVL, all whilst navigating over undulating and challenging terrain of any type.
Alongside its class-leading precision and accuracy, Ethernet and serial output means that Syrinx can be employed as a standalone DVL, as part of an integrated navigation system, or perform both functions at once, allowing both vehicle pilots and science teams to simultaneously share the output from Syrinx. Syrinx has been designed to be easy to install, set-up and use, and can make use of existing DVL mounting arrangements on host vehicles. Available in depth ratings up to 6,000 meters, CSSF selected the 4,000 meter rated, corrosion resistant titanium model for ROPOS. It will be fitted to the vehicle’s dedicated navigation instrument skid which keeps any offset errors between sensors to a minimum.
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 said, “We’re delighted that CSSF is the latest scientific organization to recognize 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.” She added, “And given the strength of international currencies against Sterling at the moment, our UK-manufactured Syrinx represents excellent value for money.”
