Sub-Bottom Imager™
The Sub-Bottom Imager™ (SBI) is a 3D imaging tool. This tool is an evolution of the Acoustic Corer™ technology to advance conventional acoustic applications.
The SBI interfaces with an ROV and its technology is a unique fusion of beam forming, synthetic aperture sonar (SAS) processing, parametric and chirp transmission. The SBI is used for site assessment prior to pipeline laying to identify geo-hazards and debris lying in, or near, the pipeline route. It will be employed to determine the as-laid burial position of the pipeline and to conduct routine depth of burial and out-of-straightness re-surveys.
The SBI has applications for imaging buried high voltage direct current (HVDC) cables to provide cable position and depth of burial.
The SBI delivers:
- High-resolution volumetric images 5m wide with a 5m swath
- Real-time data processing
