Bubble Gun Family Of Ultra-portable Seismic Systems
Falmouth Scientific, Inc. (FSI, USA) is further developing its product line of HMS-620 Bubble Gun seismic systems and has announced two important enhancements. These systems are suited for small-boat, shallow-water surveys. Data collected with the HMS-620 rivals that of much larger, heavier and more expensive air-gun, boomer and sparker systems, and its small size makes it easily deployable without the need for heavy machinery, winches or cranes
Bubble Gun systems utilise a 15 cubic inch air volume to generate narrow band, low frequency acoustic signals. This proven technology provides superior signal penetration through coarse sand, gravel tills, and other difficult to penetrate sediments.
New Dual Source System
By adding a second transmit channel to the existing transceiver enclosure, and by synchronising the two signal generators, FSI has realised higher energy output, which results in deeper signal penetration. The two Bubble Gun source transducers can be mounted together on one tow vehicle, or can be configured as two separate single-source vehicles.
New Battery-powered 24VDC Option
All of FSI’s Bubble Gun systems can be fitted with a 24VDC power option which allows them to be powered by lead-acid marine batteries. This means that you can perform shallow water seismic surveys without the need for a generator or ship’s power. Two deep-cycle marine batteries will allow over ten hours of survey time on a single charge. No generator noise, no fuel, no exhaust, all with no degradation of the data.
The HMS-620 and other FSI products are available in Booth W40 at Ocean Business 2013, to be held from 9 to 11 April 2013 in Southampton, UK.
