Wesmar's Navigation and Security Sonar on Display

press release
Thursday, February 09, 2012
Wesmar NS860 sonar.

For cruise ships and excursions vessels, the NS860 sonar offers both open water and shallow water protection. In open water it is a tool for avoiding objects near the surface such as icebergs or lost containers. In shallow water, it is used to locate large rocks, reefs, shoals and objects sunken in shipping lanes or navigable channels.

 

WESMAR’s NS860 features precision beam stabilization for maximum range performance in hazardous close-to-shore and shallow-water situations. The NS860 paints a sonar picture of the underwater, 360 degree around and beneath the vessel, giving captains a clear picture of suitable depth and obstacles to avoid.

 

  • Narrow Beam

WESMAR’s NS860 design uses a large multi-element array that provides the narrowest, most highly concentrated 110 kHz sound beam ever developed. It projects a narrow sound beam that substantially improves detection ranges of near-surface and shallow-water hazards never before achieved.

 

  • Stabilized Beam

 

To keep the beam focused the transducer array itself is stabilized with WESMAR’s next generation advanced gyro-electric stabilization. This stabilization provides finite alignment of the sonar array in rough sea conditions and stops the sonar sound beam from encountering the surface or seabed when the sonar is scanning at long ranges ahead of the vessel.

 

  • Deeper Deployment
     

The NS860 incorporates a three position long-stroke M18 hoist. The LS-M18 will deploy the sonar dome down to a maximum depth of 160 cm below the vessel’s hull. This extended deployment capability keeps the sonar dome away from vessel-generated cavitations and noise and allows the sonar to provide a clear picture.
