Innomar SES-2000 quattro Sub-Bottom Profiler

Innomar SES-2000 quattro parametric sub-bottom profiler The Innomar SES-2000 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 SES-2000 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 SES-2000 SBP data. For three-dimensional visualization of the sub-bottom data, Innomar provides a gridding tool and third-party visualization software.

Four highly portable transducers can be assembled in different ways to provide optimal solutions for different survey tasks:

  • Single beam mode (SBM): square array for best sediment penetration (one survey line),
  • Dual beam mode (DBM): two transducers combined (two survey lines),
  • Triple beam mode (TBM): line array using two transducers combined (three survey lines),
  • Quad beam mode (QBM): line array using single transducers for highest data density (four survey lines).
