Description
The Deep Ocean RIC Series is a heavy duty hydraulic vibracoring system that can operate at depths up to 2000 meters. The unit can produce 5,500 ft/lbs of impact force at a frequency of 2000 vibrations per minute (vpm). Multiple options of the system can be provided including autonomous or surface control. Cores can be collected to 8 meters penetration depth. The standard system comes with dual safety controls, penetrometer and altimeter. Custom systems can be built for full ocean depth, with imaging systems, or with a Cone Penetrometer tool package integrated.

Category Description
Vibracoring is a technology and a technique for collecting core samples of underwater sediments and wetland soils. The attached core tube is driven into sediment by the force of gravity, enhanced by vibration energy. The vibrations cause a thin layer of material to mobilize along the inner and outer tube wall, reducing friction and easing penetration into the substrate. The liquid spaces in the matrix allow sediment grains to be displaced by the vibrating tube. Vibracoring works best on unconsolidated, heterogeneous sediments and soils.
All Ocean Instruments Vibracore systems include a proprietary control system to adjust the force output frequency of the vibrohead. Our Vibracorer systems can also be provided with Ocean Instruments SMRT unit providing real-time depth monitoring and optional video and CTD outputs.
