Innomar SES-2000 ROV Sub-Bottom Profiler

Innomar SES-2000 ROV parametric sub-bottom profiler (subsea housing and transducer) for operation on remotely operated vehicles (ROV) The Innomar SES-2000 ROV model performs like a Innomar SES-2000 standard SBP and is intended to be used on ROVs working up to 2,000m below sea level.

The high ping rate, a small footprint and the possibility of transmitting sound pulses over a wide frequency range ensure echoprints with excellent resolution and very good sediment penetration. Electronic beam stabilization along track (pitch) is used to compensate movements when the ROV follows the seabed.

A user-friendly Windows data acquisition and system control software (SESWIN) is used for remote (Ethernet) operation. The Innomar SES-2000 ROV model 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.

This model has been substantially upgraded in 2013 to reduce size and weight and improve handling during mob/demob. One unit is available for renting.
