Innomar Device / Instrument
"quattro" SBP
Four-transducer parametric SBP for very high data density in extremely shallow water, e.g. pipeline, cable, site-risk and archaeological surveys.
Description
The Innomar "quattro" uses four transducers to deliver very high data density in extremely shallow water. Innomar provides a gridding tool and third-party visualisation software for 3D display of the sub-bottom data, and the system can run in quattro mode or single beam mode. It was launched in 2015 as the "SES-2000 quattro"; the latest generation was introduced in 2021.
Key features
- Water depth 0.5 – 600 m; sediment penetration up to 50 m
- Frequencies 4 – 15 kHz
- Ping rate up to 15 Hz (quattro mode) or 60 Hz (single beam mode)
- Heave compensation; roll and pitch in post-processing
- Power consumption <300 W
Applications
- Pipeline and cable surveys
- Risk mitigation at offshore building sites
- Archaeological surveys
Software and data
- Full-waveform data, exportable as SEG-Y for any seismic software
- Operated with Innomar SESWIN acquisition software
- Post-processing with Innomar ISE
