Sentinel Sonar Order

The US Naval Underwater Warfare Center (NUWC) in Rhode Island (USA) has placed a contract with Sonardyne Inc., Houston (TX, USA) for the supply of an additional Sentinel Intruder Detection Sonar system.     The announcement follows the completion of rigorous acceptance and readiness trials by NUWC in 2008 when Sentinel was shown to meet the US Navy's performance requirements for diver detection. The latest contract adds an additional Sentinel to the new Integrated Swimmer Defence System. This is being led by the Program Executive Office, Littoral Mine Warfare (PEO-LMW - PMS480) and the first Sentinel was delivered to NUWC... (read more)

Versatile Side-scan Sonar

JW Fishers developed a side-scan towfish with adjustable transducers. The angle of the transducers can be changed by rotating the tail section of the towfish. This allows the sonar to scan the hull of a ship for attached contraband compartments and inspect the face of a dam, bridge, or oil platform for explosive devices. Already several departments have purchased these side scans with the new adjustable transducers including the Escambia Sheriff’s Office in Pensacola (FL, USA) and the Washington County Sheriff’s Office in Stillwater (MI, USA).  Jim Anderson of Washington County’s Water Recovery Unit says to be impressed with the...

‘Killer’ AUV Sonar System

In January 2001, C&C Technologies (C&C), a company based in Lafayette (Louisiana, USA), introduced the first commercially successful autonomous underwater vehicle (AUV) to the offshore industry. The AUV’s survey sensor suite, which included an EdgeTech side-scan sonar and sub-bottom profiler, performed well in the Gulf of Mexico and Brazilian offshore environments. However, West Africa proved more challenging – particularly for the sub-bottom profiler. C&C soon began searching for alternative technologies to provide better sub-bottom profiler penetration and higher resolution side-scan sonar imaging.Jim Chance, C&C Technologies (USA) Art Kleiner, EdgeTech (USA)<P> Narrator: Fast forward to the early autumn of 2004… C&C...

Obstacle Avoidance Sonar

Sonardyne International, UK, has announced the launch of its new Navigation and Obstacle Avoidance Sonar, NOAS, at NAVDEX 2013 in Abu Dhabi. Designed for use on submersible vehicles, NOAS enables faster, safer and more efficient navigation by detecting and classifying potentially hazardous underwater obstacles in its path. Unveiled on the first day of the exhibition, NOAS provides a unique combination of very long range 2D navigation performance, 3D object detection and class leading intruder detection in a single compact sonar. In 2D mode NOAS provides the crucial long range navigation information enabling underwater vessels to steer a safe course. When... (read more)

Side-scan Sonar Demonstration

GeoAcoustics has launched Sonar 2094 Digital. A series of seminars and demonstrations were held by Simrad Spain, the local Kongsberg office, in November and December of the past year for their naval, scientific and industry customers. The capabilities of this technology for environmental mapping, engineering and archaeology surveys as well as object detection and classification were shown in various places along the Mediterranean coast.   Sonar 2094 Digital is the successor of the Dual Frequency Side-scan sonar, which was first launched in 1996 and developed into an industry standard, with over 1,000 units sold worldwide. Sonar 2094 Digital combines the... (read more)
