EBP Cable & Pipeline Subbottom Detection


The new STEMA EBP Cable & Pipeline detection system is a seismic system, which is able to detect linear objects as (power)cables and pipelines and gives the depth of burial.
It is a passive system which does not require any physical connections to the cable, assuring full operational functionality of the cable during detection.

The EBP-15 cable detection system consist of the following components:
Transducer array:
The signal source consists of 2 transducers which will be used in a dedicated frequency setup (3-8 kHz), configuration and geometry which optimal for cable detection.

Transceiver & STEMA USB AD Card:
The transceiver actually generates and sends the seismic signal to the transducer array. The STEMA USB AD Card receives the amplified seismic signal from the transceiver and transfers it in a high resolution digital form to the seismic acquisition PC or laptop.

STEMA Silas Software:
This high resolution seismic package consist of Silas acquisition software and Silas processing software with a specifically designed cable/pipe line detection module.

The contacts when that are registered by the EBP – 15 translates this via the Ultra High resolution processing software SILAS in a display of a clear hyperbola, this hyperbola is read by the software to be the probable top edge of an object, SILAS recognizes these contact points and presents the user with a marking of the object.as can be seen on the right.
The STEMA Silas Cable Processing package enhances the high resolution data acquired from the EBP-15 system by integrated processing techniques and applies an automated contact recognition technique.

The contact recognition consists of the automated determination of two parameters
• Semblance of apex of hyperbola (top of contact).
• Power of hyperbola.

These parameters are quality figures which also enable a more objective classification of detected contacts. Plan view with track lines, contacts and multi-beam data.
The contact data and its parameters can be managed and inspected in several displays:
• Plan view with Geotifs
• Contact display from
• Navigation Vie

The STEMA Silas Cable Processing package can be interfaced with DXF-files and contacts from other data sources such as:
• Multibeam
• SSS
• Magnetometer
• GPR

This integration permits the user to present a full cable passport, with multiple data sources to illustrate the exact cable lay.
