Energy Sources, CSP Units
Model
The CSP-NP is a compact, lightweight seismic power supply. Recently upgraded, it incorporates reverse voltage technology that allows compatibility with the Dura Spark compact high resolution sound sources. The CSP-NP is ideal for small vessel coastal geophysical surveys.
The CSP-Nv incorporates microprocessor control and configuration for greater flexibility and reliability, whilst retaining a fail-safe logic design. It is the driving force behind applied acoustics’ Dura-Spark range of sound sources, and is also suitable for use with the S-Boom and single plate boomer systems.
The CSP-SNv has been engineered for use with the dual deck Dura-Spark UHD 400+400 catamaran, providing flip-flop and fire delay modes of operation. It offers a solution to the industry requirement of acquiring UHR seismic data in challenging environments with a ≤1m shot point interval.
The CSP-S12000 is a compact ‘all-in-one’ power source for marine sparker applications, specifically the applied acoustics Delta Sparker. The high charge rate allows for fast, high-energy sound pulses from the sparker that is used in deep water geohazard surveys
