Innomar "deep-15" Sub-Bottom Profiler

Innomar "deep-15" SBP

Innomar "deep-15" SBP

The Innomar "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. For best data quality the sound beam is electronically stabilized at transmit and receive.

The picture shows the topside electronics (one transmitter unit and one receiver unit) and one of eight transducer sections.

The Innomar "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 SBP data.

This model has been launched in 2019 as "SES-2000 deep-15".
