Innomar SES-2000 deep-36 Sub-Bottom Profiler

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

The Innomar SES-2000 deep-36 parametric sub-bottom profiler is designed for offshore applications down to 6,000m water depth.

This model is available in two versions. The basic version features heave and roll compensation while the "POD" version offers additional pitch compensation.

The Innomar SES-2000 deep-36 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.
