Innomar "deep-36" Sub-Bottom Profiler

Innomar "deep-36" SBP

Innomar "deep-36" SBP

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 "RP" 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", the latest generation was introduced in 2021.
