The "Innomar deep-36-RP" parametric sub-bottom profiler is designed for offshore applications down to 6,000m water depth. This model features heave compensation as well as roll and pitch beam stabilisation for improved data quality in bad weather. The "Innomar deep-36-RP" 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 "Innomar deep-36-RP" SBP is similar to our "Innomar deep-36" model, but with additional pitch beam stabilisation.
