3d High resolution Sub bottom Object detection

GEOxyz offers  industry-standard tools for pipeline and cable tracking, GEOxyz are also able to offer the revolutionary Silas 3D system for cable tracking. The Silas 3D system is a unique linear sub-bottom profiler with multichannel receiver array which can be used for accurately locating buried all types of subsea cables.

The Silas 3D system we use at GEOxyz is a complete data acquisition, processing and interpretation system, that covers a wide range of tasks and shows live line tracking in the helmsman display.
The  Silas 3D system is a passive cable detection system which uses an acoustical pinger source. The sound source consists of an array of transducers which are mounted in a frame over the side of a vessel, on a ROV or depressor. 

This sound source in turn is connected to a transceiver which actually sends the signal.  Reception of the signal is executed by an array of hydrophones mounted on a frame. 
Pipeline and cable contacts are detected by sailing longitudinal lines over and parallel to the object. The beam pattern of the S3D cable detection system is approximately elliptical. The system combines high penetration with to ultra-high resolution, allowing for detailed interpretation and object detection.


Deliverables

• Real time Depth of Burial (DOB)
• Depth of Cover (DOC)
• Site investigation / Layer detection
• Object / Cable / Pipeline detection / UXO

As well as being able to offer industry-standard tools for pipeline and cable tracking, GEOxyz are also able to offer the revolutionairy Silas 3D system for cable tracking. The Silas 3D system is a unique linear sub-bottom profiler with multichannel receiver array which can be used for accurately locating buried all types of subsea cables.
