Hydraulic Vibrocorer (3m-9m)



OSIL’s Hydraulic Vibrocorer has been designed as an easy to use, easy to transport modular system capable of collecting cores up to 9m in length. 

 

Two large hydraulic rotary vibrators produce the necessary vibration with variable force. The sealed Vibrocorer head housing for the motors is designed to operate in water depths of up to 600m.
 

The modular system is easily assembled dockside or on the vessel itself into either a 3m, 6m or 9m system before deploying over the stern.

 

Once the unit is on the sea floor the hydraulic 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.

 

The Hydraulic Vibrocorer is a modular system that can be quickly and easily deployed, delivering a well defined sample of 96mm diameter.

 

Depending on the depth of operation, a suitable winch is delivered which contains the umbilical between the vibrocorer and the control unit. This ruggedized control unit is designed to operate in all weather conditions, and in salt water environments.
