Innomar medium-100 SBP

The Innomar medium-100 sub-bottom profiler acquires full-waveform data in water depths from two meters down to 2,000 metres. The layer resolution is better than 10cm and seabed penetration is up to 70 meters, depending on the sediment type and noise level. Main applications are in coastal and shelf areas, the built-in active beam stabilisation significantly improves data quality in rough weather conditions.

Description

The Innomar medium-100 sub-bottom profiler acquires full-waveform data in water depths from two meters down to 2,000 metres. The layer resolution is better than 10cm and seabed penetration is up to 70 meters, depending on sediment type and noise level. Main applications are in coastal and shelf areas, the built-in active beam stabilisation significantly improves data quality in rough weather conditions.

The system is portable to be used on vessels of opportunity with very fast and easy mob/demob. The transducer can be pole-mounted or deployed in a moon-pool. For permanent hull-mounting a mounting frame with optimized shock absorbers is available.

The Innomar medium-100 data can be processed with any seismic software (SEG-Y format), but Innomar also provides the ISE post-processing software specialized on the Innomar SBP data.

Included features:

Heave compensation and Roll beam stabilization (external sensor required)
24 bit SLF full waveform data acquisition (sub-bottom data)
Multi-ping mode for maintaining a high pulse rate in deep waters
Multi-frequency signals
CW pulses with user selectable centre frequency (3.5 ...15kHz) and bandwith
LFM chirp (5 – 15 kHz)
