OPV Sentinels

Sonardyne delivers first two ship-fit SENTINEL diver detection sonars

Sonardyne International, a maritime security company, has tested and delivered two ship-fit SENTINEL diver detection sonar as part of a wider contract to equip a fleet of Offshore Patrol Vessels (OPV), currently under construction in the Far East, with a fully integrated force-protection capability. Working with MARSS Group’s NiDAR long-range maritime surveillance system, the SENTINELs, of which more are to follow, will provide complete underwater domain awareness by detecting unauthorised divers and subsurface vehicles approaching the OPVs and the assets they protect.

Ross Gooding, Business Development Manager for Maritime Security at Sonardyne, said “This has been an exciting project for us and our partners at MARSS to be involved with; reaching this latest milestone demonstrates our combined commitment to supply, install, commission and support this important new OPV fleet in the region for many years to come,”

For this contract, MARSS through-hull technology will be used to fit SENTINEL sonar head onto the OPVs while minimising footprint within each hull. NiDAR will control and monitor the sonars that can be lowered automatically to establish an instant, 360 degree monitored zone around large naval ships at anchor, or the entry to a port or harbour.

SENTINEL detects, tracks and classifies underwater threats at up to 1,200m range, thus facilitating the rapid deployment of a perimeter intrusion capability to help safeguard commercial harbours, naval vessels, private yachts, critical national infrastructure (CNI) and waterside residences. The ability to reliably detect underwater intruders or vehicles in real-time at long range is essential to provide ample time for ship security officers to react to a security breach. Vital minutes can make the difference between successful threat interception and divers and vehicles being able to deliver their attack.
