Geo-Corer 6000
Available Configurations
3m ● 6m
Key Features
  • Proven performance & high quality cores
  • 30 kN impulse at 30 Hz for fast penetration
  • Reliable, lightweight & cost effective
  • Modular construction (cores of 3 m or 6 m)
  • Pivoting core barrel for horizontal retrieval
  • Water injection for deep cores of 12 m and applications onshore & in transition zone
  • Optional pre-pressured or compensated model for deep water operation
High Frequency Vibration
The Geo-Corer 6000 Vibrocorer is a high frequency (28 Hz), electrically-driven vibrocoring system. It can penetrate fast (thereby enhancing the quality of the core) into all common unconsolidated sediments, including compact sands and stiff clays, and structureless chalk.

Deep Water Operation
The Geo-Corer, new models built after 2010, is rated to a maximum water depth of 300 m. It can be upgraded to the pressure-compensated version for operation in water depths down to 600 m and more.

Variable Coring Parameters
The two standard configurations are designed to take high quality cores of 3 m or 6 m length, in ordinary PVC liners with an internal diameter of 106mm. The penetration force can be adjusted by varying the deadweights on the vibrator head.

Lightweight Structure & Small Vessel Operation
This modular vibrocorer system can be assembled manually in less than 2 hours (a crane is required to bring it upright) and can be deployed from a relatively small vessel. Given its lightweight construction and smart pull-out system, it requires a limited hoisting power of maximum 5 tonne. Its low overall weight minimises transportation costs.

Pivoting Core Barrel Head
The pivoting corer head allows rapid change-out of the core barrel and easy retrieval of the core liner, while the vibrocorer remains in the upright position.
