In addition, Alpine has over 40 years of experience as a leader in the manufacturing and use of Vibracore sediment sampling equipment. Alpine developed and produced the first Vibracore in response to the Sand Inventory Program, which was initiated in 1964 by the U.S. Army Corps of Engineers’ Coastal Engineering Research Center (CERC). The Vibracore, and the techniques developed by Alpine for its use, have now become a key element in determining suitability of sand for replenishment material.
Today, Alpine provides Vibracoring services worldwide to companies and government organizations engaged in activities ranging from diamond mining to channel dredging, from pipeline and platform installations to environmental monitoring. Alpine manufactured Pneumatic Vibracores range from compact units capable of being deployed from small platforms in shallow water, to powerful larger units capable of taking forty (40) foot cores in challenging sediments.
Alpine manufactured Electric Vibracores are designed to offer up to forty (40) foot coring capability in deep waters. In addition, all Alpine Vibracores can also be outfitted with a high pressure Jetting System and a Corelog System:
● The Jetting System uses high pressure water to virtually guarantee achieving
target sample recovery in the most sediments when conducting multiple runs.
● Corelog is a proprietary logging and processing system capable of recording in
real time a variety of important data on the Vibracore’s progress through
sediment. The data can then be immediately processed into graphical format
for review or stored for later analysis.
