Innomar SES-2000 sixpack Sub-Bottom Profiler

Innomar SES-2000 sixpack parametric multi-transducer sub-bottom profiler The Innomar SES-2000 sixpack 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 sixpack 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.

Transducer Configurations

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

Hex beam mode (HBM)
  • line array using single transducers
    → six survey lines per sailed profile
  • highest data density for 3D visualisation
  • transducers pinging subsequently
  • variable transducer separation (equidistant)
Innomar SES-2000 sixpack HBM
Penta beam mode (PBM)
  • line array using two transducers combined
    → five survey lines per sailed profile
  • high data density for 3D visualisation at increased power
  • transducer groups pinging subsequently (overlapping)
  • transducers needs to be close together (equidistant)
Innomar SES-2000 sixpack PBM
Triple beam mode (TBM)
  • line array using two transducers grouped
    → three survey lines; increased power
  • high data density for 3D visualisation
  • transducer groups pinging subsequently
  • variable separation of transducer groups (equidistant)
Innomar SES-2000 sixpack TBM
Dual beam mode (DBM)
  • line array using three transducers grouped
    → two survey lines; increased power
  • high data density for 3D visualisation
  • transducer groups pinging subsequently
  • variable separation of transducer groups (equidistant)
Innomar SES-2000 sixpack DBM
Single beam mode (SBM)
  • all six transducers grouped
    → one survey line; maximum power
  • transducers pinging together
  • highest possible range / penetration
  • transducers needs to be close together
