Innomar SES-2000 medium-100 SBP

Innomar SES-2000 medium parametric sub-bottom profiler (top side unit and pole-mount transducer)

The Innomar SES-2000 medium-100 parametric sub-bottom profiler is designed for offshore applications down to 2,000m water depth. The transducer can be either mounted over-the-side or in the hull.

The Innomar SES-2000 medium-100 SBP acquires full-waveform data that can be processed with any seismic software (SEG-Y format). Innomar also provides the ISE post-processing software specialized on the Innomar SES-2000 SBP data.

Application examples are given in the Deep Water Applications section.

A new version with reduced weight and size has been released in 2016 to improve equipment handling for mobile installations.
