UNDERWATER VIBROCORING SYSTEMS

Vibrocoring is an efficient and versatile procedure for obtaining long, well-preserved cores in consolidated water-saturated sediments from wetlands, harbors and lakes to the deep ocean. It allows for deep penetration in a single deployment and a high core recovery where other approaches such as rotary-drilling, dart-coring, or cf-augering prove either inappropriate or impractical.

Vibrocoring on Small Inflatables in Marsh
For a long time, however, a more widespread use of vibrocoring techniques was hampered by the weight and bulk of the few existing vibrocorers with their cumbersome ancillaries and by the resulting high costs of their deployment.

San Diego Bay.
Our SUBMERSIBLE ELECTRICAL VIBROCORERS, developed through years of fieldwork in distant waters, endeavored to correct this problem. They are sturdy and powerful, yet light and compact. They can be airfreighted at minimal cost anywhere in the world to be operated from local vessels-of-opportumity and even from inflatable barges or helicopters. Our patented "buoyant-frame" offers a practical way to set them upright on the seafloor and to guide them. Designed to withstand deep ocean pressures, rough seas and arctic cold, fully enclosed, easy to clean, our Vibrocorers have also become tools of choice for retrieving cores in contaminated sediments and hazardous environments.
