A sophisticated, electrically driven, vibrating coring system that can extract optimum samples at speed in depths of up to 1000 m or more.

The original Med-C Vibrocorer – VC(VKG) 3/6/9 – has been successfully operating in harsh climates and challenging deep sea conditions for many years. Satisfied clients include Federal Maritime and Hydrographic Agency Germany, MMT Sweden, Fugro and Geo Marine Survey Systems (Geo-Corer) Netherlands, Next Geosolutions Italy and Jan De Nul Belgium.

Our Vibrocorer is available for full purchase including all additional equipment and consumables required. If your operation only requires the Vibrocorer for a set period of time, we can provide the equipment on a rental or lease basis regardless of your project length.

Can come with a measuring device developed specifically for in situ thermal measurements in marine sediments, typical for shallow seas, coastal and continental shelf regions.

Pros & Limitations

Just 5-minute penetration and extraction time ( with unlimited runtime )

Unique decoupling design resulting in minimum vibrational deadweight

Can be operated on smaller vessels with winch/lift capacity of just 20 kN

A standard core barrel length of 3 or 6 m with split barrels of 9 m

All equipment and consumables are manufactured to the greatest quality to ensure less downtime and less operational cost.

Works at depths of up to 1,000m
