The Electric Driven Vibrocorer has been designed as an easy to use, easy to transport modular system capable of collecting cores up to 6m in length. Two large electrical motors mounted side by side power two concentric weights, which produce the necessary vibration. The sealed and waterproof Vibrocorer head housing for the motors is designed to operate in water depths of up to 120m.
The modular system is easily assembled dockside or on the vessel itself into either a 3m or 6m system before deploying over the stern. Once the unit is on the sea floor the high power vibrator motors are engaged and drive the core barrel with PVC liner into the bed. The cutting shoe and core catcher have been specifically designed to minimise the sample disturbance. The unit has been designed for easy horizontal recovery on to the vessel and then easy recovery of the core barrel once back on deck.
