- Model SES-2000 Medium-100 - Parametric Sub Bottom Profiler

0

The 'Innomar SES-2000 medium-100' parametric sub-bottom profiler is designed for offshore applications down to 2,000m water depth. The transducer can be either mounted over-the-side or in the hull. The 'Innomar SES-2000 medium-100' 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 SES-2000 data. Application examples are given in the Deep Water Applications section. New version with reduced weight and size released spring 2016 to improve handling for mobile installations.

Included Features

  • Roll beam stabilization
