Dutch survey company Deep BV has purchased underwater acoustic technology supplied by Sonardyne International, UK, to support its inshore, harbor, coastal and offshore activities. 

 
Within days of the order, the two Mini-Ranger 2 Ultra-Short BaseLine (USBL) tracking systems and WSM 6+ mini transponders were delivered to Deep BV’s headquarters in Amsterdam and were put straight to work during an operation to search for unexploded ordnance (UXO). 
 
Sonardyne said Mini-Ranger 2 boasts a number of features that makes it suited for underwater operations such as UXO surveys which require high accuracy positioning but without the cost and complexity associated with a deep water USBL solution. It can simultaneously track 10 targets at fast update rates, it is quick to install on small vessels and has a tracking range of 995 meters, extendable to 4,000 meters. 
 
For its first project with Mini-Ranger 2, Deep BV installed one of the systems on board its 15 meter, twin hull research vessel, Deep Volans, and configured it to track a WSM 6+ transponder mounted on a remotely operated towed vehicle (ROTV) Iron Lady. Accurate positioning is paramount for the Iron Lady’s control software in order to ‘fly’ the 6-meter-wide, gradiometer UXO set-up just two meters above the seabed.
 
Klaas Visser, Chief Technology Expert at Deep BV said, “We’ve been a user of Sonardyne’s pre-generation Scout USBL system for several years and pleased with the results it’s delivered. However, now was the right time to replace these systems and upgrade to Sonardyne’s 6G product family with all of its attractive features and performance gains.” 
 
Speaking about the contract, Sonardyne Sales Manager, Alan MacDonald explained that Mini-Ranger 2 is ideally suited to the type of work carried out by Deep BV. “For example, the transceiver that’s used to track transponders can be mounted alongside the multi-beam system in the moon pool of the Deep Volans. Then afterwards, it’s simple to move it to a different vessel. And thanks to its excellent noise rejection properties, the system’s optimized to provide reliable tracking in shallow water, near the surface where vehicles such as Iron Lady operate.”
