Innomar SES-2000 deep-15 — full ocean depth SBP

Innomar SES-2000 deep-15 parametric sub-bottom profiler (one transceiver unit)

The Innomar SES-2000 deep-15 parametric sub-bottom profiler is designed for offshore applications down to 11,000m water depth.

This model features full motion compensation for heave, roll and pitch vessel movements.

The Innomar SES-2000 deep-15 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.
