Sonardyne Asia Pte. Ltd has announced the signing of a major contract in China for its Sentinel Intruder Detection Sonar (IDS) system. Designed to protect vessels, ports and waterside installations from intrusion by divers, swimmers or surface vehicles.

Sentinel uses innovative sonar technology and intelligent software to automatically detect, track and classify an underwater threat at long ranges. The order, valued at over US$1.5M, is for the protection of an undisclosed infrastructure project in China and includes the provision of multiple, linked sonar heads to provide wide area underwater security coverage. Delivery and installation of the system is scheduled to occur during the summer of 2009.

Sentinel systems are now deployed and operational in America, Europe, Africa, the Middle East and Asia where they are protecting commercial property, strategic infrastructure, coastal zones, ports and harbours, VIPs and military installations. The system has shown a 100 per cent success rate in detecting targets at long ranges and in differentiating between divers, surface swimmers and non-threats such as pleasure craft, large fish and cetaceans.

Sonardyne attributes this high level of performance to the fact that unlike other diver detection systems, Sentinel is a not a hybrid of an existing sonar. It has been specifically designed to meet the challenge of tracking underwater targets in a wide range of marine environments reliably and cost-effectively.

Small and lightweight, the system’s sonar head can be easily deployed from a vessel or harbour environment. Capable of providing 360 degrees of sonar coverage, it can operate as a stand-alone portable system or configured with multiple, networked sonar heads so that very wide areas, such as large ports and entire water-front locations, can be permanently protected.

“This contract is the result of significant teamwork with local representatives and technical authorities in China to provide a solution that matched the customer’s rigorous requirements. It represents a major step forward in the recognition of the need for reliable underwater security and how the latest sonar technology can be used to achieve it.”
