State-of-the-Art Multibeam Sounding Equipment

Category:

Surveying

Description:

The SeaBat 9000 series are small, lightweight, and highly accurate multibeam echo sounders that

can be installed over the side or through the hull of a small vessel, dredge, ROV, or ocean going

vessel. The transducers can be mounted at various angles, providing the ability to look out to the

side, either under moored vessels or areas that would obstruct a surface vessel. The current range

of SeaBats offer swath angles of 90 to 180 deg.

Other Features:

1. Complies to IHO accuracy.

2. Narrow beams.

3. Lightweight and portable.

4. Vessel and ROV mountable.

5. Multibeam imagery upgradeable.

6. Uses high accuracy bottom detection method.

7. Real-time quality control.

Using sonar, each beam looks at the seafloor and provides information on what it sees. With the

SeaBat Systems being able to update all the beams simultaneously, up to 30 times per second,

any object moving through the beams can be seen and recorded. The SeaBat can be installed on a

moving platform (boat, submarine, underwater vehicle) and any movement will not interfere with

the SeaBat's performance.

The Seabat can be used to obtain more accurate and faster bathymetric data for dredge surveys,

and can also be mounted on the dredge itself to indicate "real-time" dredge survey information to

the operator prior to moving ahead.
