Innomar "deep-36" Sub-Bottom Profiler

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

The Innomar 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 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 SBP data.

The first generation of this model has been launched in 2007 as "SES-2000 deep-36".

Application examples are given in the Deep Water Applications section.
