Products Sonardyne Ranger 2 Chosen for Russian Salvage Vessel Sonardyne?s Ranger 2 acoustic positioning technology has been selected by Transas for use on two new build ice-class multi-purpose salvage ves- sels (MPSVs, the project is developed by Marine Engineering Bureau) commissioned by the Russian Ministry of Transport. The vessels are cur- rently under construction at Nordic Yards in Germany and will each be  tted with dual Ranger 2 Pro systems. In conventional Ultra-Short Base- Line (USBL) operating mode, Ranger 2 calculates the position of a subsea target, such an ROV or tow sh, by measuring the range and bearing from a vessel-mounted transceiver to an acoustic transponder  tted to the target. By interfacing it to a dynamic positioning system, Ranger 2 can be used to simultaneously help maintain the vessel?s own position. In Pro con gura-tion, Ranger 2 adds support for Long and Ultra-Short BaseLine (LUSBL) acoustic positioning. The technique uses a network of transponders de- ployed on the seabed to offer precision and repeatability and is widely used for applications where maintaining a reliable vessel position is a critical operational requirement. Underwater Cutting Rod Broco Underwater offers the new ad- vanced design Broco Ultrathermic Cutting Rod PLUS. Based on a new patent-pending design, Broco said its new underwater cutting rod deliv- ers 20% more cutting and burn time than the same size prior generation rod. According to the manufacturer, the new Broco Ultrathermic Cutting Rod PLUS increases burn time 20%, on average, for a 3/8? diameter by 18? long rod. Broco Underwater Ultra- thermic Cutting Rod PLUS rods are currently available in 3/8? diameter by 18? length, and will be available in 3/8? diameter by 36? length later this year. Engineered Syntactic Systems Expands High-Performance Buoyancy Offering Engineered Syntactic Systems (ESS), a supplier of foam buoyancy solutions, announced plans to extend its line of syntactic products to support more traditional oceanograph- ic implementations. The addition of modular product options enables ESS to supply more customers with great perfor- mance in a wider range of densities. The team at ESS has been serving the oceanographic industry for more than 30 years. As a supplier of ß otation technologies for advanced customer applications, ESS combines engineering, design and manufacturing know-how to deliver the best depth performance in the business - from the surface to depths of 11,000m. ESS syntactics are lightweight, engineered foams designed to withstand signi Þ cant hydrostatic pressure while delivering optimum performance. ?We are expanding our product offering to provide custom- ers with a one-stop-shop for best-in-class buoyancy prod- ucts,? said Thomas Murray, managing partner at Engineered Syntactic Systems. ?We recently discovered that there is a need for readily available, off-the-shelf products such as cable ß oats and Acoustic Doppler Current Pro Þ ler (ADCP) buoys. We are nimble enough to respond quickly and work closely with customers to provide cost-effective solutions that will address these needs.? Sonardyne?s Ranger 2 Pro will be installed on new build MPSVs, like the one modeled above, for complex underwater positioning and DP sta- tion keeping operations.
