New long-life sparker

Applied Acoustics introduced its evolutionary new sparker at Ocean Business in Southampton. The Dura-Spark 240, the latest in a long line of seismic sound sources manufactured by the company, offers high resolution sub-bottom data, up to 25cm, in water depths up to 1000m.

The new Dura-Spark has been designed to provide a stable, repeatable sound source for sub-bottom geophysical surveys. Its new features include long life, durable electrodes that produce a consistent pulse signature and keep operational maintenance to a minimum. This provides increased equipment reliability and survey efficiency as the sparker tips rarely need replacement.

Flexibility is achieved by having 3 arrays of 80 tips allowing the operator to tune the source from the vessel to its application. In addition, a selectable source depth allows the sparker to be used in both shallow and deep waters.

The new Dura-Spark is based on the CAT300 catamaran that provides a stable platform whilst under tow and is easily deployed from all survey vessels. Its seismic power is supplied by the Applied Acoustics CSP-N, an industry leading design with exceptional safety standards, offering 2000J/s peak discharge rate.

The Dura-Spark 240 is ideal for high and ultra-high resolution geophysical surveys for both single and multi-channel data acquisition. Now with long life, durable electrodes the Dura-Spark 240 will set new standards for quality and reliability together with unparalleled operational cost savings.
