Acoustic Coring
3D acoustic sub-seabed survey producing a 14 m diameter acoustic core to more than 50 m depth, identifying boulders down to 0.2 m.
Description
The Acoustic Corer bridges geophysical and geotechnical site investigation by building a high-resolution 3D acoustic volume below the seabed, in which geohazards are identified and geological units interpreted. It combines a high-frequency chirp, a low-frequency chirp and a multi-frequency parametric transceiver.
Key features
- 14 m diameter acoustic core
- Penetration of more than 50 m below seabed, depending on lithology
- High-frequency chirp 4.5-12.5 kHz and low-frequency chirp 1.5-6 kHz
- Detects boulders down to 0.2 m
Applications
De-risking offshore installations such as wind farm foundations and substations.
