Innomar SES-2000 medium-100 Sub-Bottom Profiler

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 SES-2000 data.

Application examples are given in the Deep Water Applications section.

New version with reduced weight and size released spring 2016 to improve handling for mobile installations.
