Overview
The Conrad Vibracorer P291 is an installation for taking samples of underwater bottom and
seafloor for geological / geotechnical investigation to a depth of 45 meters. Because the
complete installation is galvanized it can be used in seawater conditions without problem.
Based on experience with development of the Geodoff 1 and 2 and the Vibracorer the current
Vibracorer P291 is capable of taking samples with a recovery rate of more than 90% under right
circumstances.
Operator convenience & comfort / Advantages
The design and operation of the Vibracorer P291 has been kept simple and due to only a few
moving parts it requires little maintenance.
For operation of the pneumatic hammer a compressor of 5 m3/min at 7 - 8 bar is required. The
total weight of 800 kg makes it possible to use the installation from a variety of smaller ships.
On the rig an electronic depth measurement sensor has been mounted to measure the penetration
depth which can be monitored on a display in the control panel on deck of the ship. With the
depth indicator and core barrel pressure gauge the progress of sampling can be clearly
monitored.
The complete installation, consumables and tools are stored in a 20ft container. Because of
this the transport is made easy.
