ROSON-ST 100

This compact and easy to handle ROSON-ST 100kn marine cone penetration test (CPT) system combines AP van den Berg’s patented SingleTwist-Rods (ST-Rods) with its ROSON seabed system. The ST-Rods provide performance equal to a string of CPT rods, but they can be easily folded onto a reel. This allows deep penetration – up to 50 metres – without the need for external CPT string support, enabling fast deployment and high productivity.

We also have Datem Neptune 3000 and 5000 CPT Systems, a frequency converter, and various winches that are suitable for deploying the ROSON-ST and other CPT systems, available for hire.
