Stema EBP Systems Ultra-high resolution sub-bottom profiling

Stema EBP Systems Ultra-high resolution sub-bottom profiling

The EBP system has been developed to yield optimal results in the area of 3 – 33 kHz sub bottom acquisition range.

Key features are:
• Easy to deploy and operate
• Multiple frequency range 3 – 33 kHz
• Easy to integrate in survey setup

The EBP system can be used in a variety of applications yielding numerous vital deliverables such as:

1. Cable & Pipeline detection at up to 7m depth of cover
2. Nautical depth limitation for safe vessel navigation
3. Object detection for cable route surveys
4. Layer identification in the sea / river bed

The choice of transducers will be recommended by Stema personnel so as to ensure optimal results in the required survey, this will be dependent on a number of environmental factors as well as the desired result which will be discussed with the client.

The EBP System offers the choice of transducers dependent on requirement and processes this via its unique USB-A/D configuration to ensure the highest resolution of your data. With the full digitization
of the analogue signal the system enables full and quick import of the acquired data into the Silas Software Suite, ensuring the high resolution transmission of data for full processing.
