Vibrocorer

The vibrocorer is an ideal research instrument to study undisturbed cores of a relative large length. VLIZ disposes of an OSIL high-power vibrocorer system that can collect cores up to 3 m long and a diameter of 96 mm. The device is deployed aboard the research vessel Simon Stevin where cores can be taken up to a depth of 100 m.

How does a vibrocorer system work?

The vibrocorer is driven by electrical motors that produce a vibration force of 89 kN. These vibrations drive the barrel, up to 3 m, into the seabed. The vibration force is high enough to sample consolidated sediments. By raising the vibrocorer a core catcher prevents the sediment from leaving the PVC liner. Once back aboard, the vibrocorer is set in horizontal position to recover the core barrel.
