Vibracorer VC

Superb geological sampling device

Description

Proven operation
The original Vibracorers VC have been succesfully operated for more than 30 years and worked at perfect satisfaction. Operated in the Atlantic Ocean, Baltic Sea, North Sea and Mediterranean Sea also at harsh climates and choppy waters it proves the best return on investment due to its sophisticated design. Well known companies such as Federal Maritime and Hydrographic Agency Germany, MMT Sweden, Fugro and Geo Marine Survey Systems (Geo-Corer), Netherlands, are fully pleased customers.

Optimized vibration frequency
The VC is an electrically driven Vibracorer system, vibrating at around 30 Hz, coring bottom samples up to 250 m (optional 1000 m) water depth with
• optimum cores in fine, middle and grain sands and any mixtures thereof
• good results in peats and sands with silty-argillaceous and/or gravel components, moreover smaller stiff stratums are penetrated too

High quality cores
Variable uploads allows you to optimise the penetration force/speed to some 2 meters per minute. This minimizes a resorting of the sediments as well as any bending of its finestructures/layers.

Operational efficiency
The specific design of cutters, catchers and valves gives you a superb filling of the barrel. The barrel length exceeds the core net length by 150 mm only. Although the runtime of the vibrator unit is unlimited, the typical penetration/retraction time is at around 5 minutes. There is no need to dismantle the core barrel while extracting the core sample. Due to its unique
barrel flip aside design allows an efficient operation with up to
40 cores/sites per day.

Easy handling
The unique design of the VC allows fast and eased assembly and disassembly of the 4 main structural components. This is an USP feature within this class of coring systems.

Reliability
The subtle design and an elaborated manufacturing garanties an outstanding reliability and a minimum of downtime.
