Innomar "quattro" Multi-Transducer Sub-Bottom Profiler

Innomar "quattro" SBP

Innomar "quattro" SBP

With its four transducers, the Innomar "quattro" multi-transducer sub-bottom profiler is designed for applications which need very high data density in extremely shallow waters. These applications include pipeline and cable surveys, risk mitigation at offshore building sites or archeological surveys.

The Innomar "quattro" 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 SBP data. For three-dimensional visualization of the sub-bottom data, Innomar provides a gridding tool and third-party visualization software.

The first generation of this model has been launched in 2015 as "SES-2000 quattro", the latest generation has been introduced in 2021.
