The seabed Cone Penetration Test (CPT) system is a common method for investigating offshore soil. This paper focuses on new subsea CPT assessing physical and mechanical properties of marine sediments. enables automatic docking dismantling the probe rods underwater. constant-rate penetration mechanism basis core component CPT, allowing rod cone to penetrate seafloor sediment. Double hydraulic cy...

Dynamic Cone Penetration Test (CPTu) profile offshore sediments by impact penetration. To exploit their results in full, the measured data are converted to obtain a quasi-static equivalent profile. CPTu conversion requires calibrated correction models. Calibration is currently done using paired (i.e., very close) and dynamic tests. It shown here that test data, which may be inconvenient acquire...

The Standard Penetration Test (SPT) is the most popular example of dynamic probing, a large category soil testing techniques. Understanding and interpretation these tests hampered by difficulties reproducing them under controlled laboratory conditions. virtual calibration chamber technique, based on Discrete Element Method (DEM), may supplement or substitute this complex experimentation. In pap...

In-situ testing techniques have proven to be successful in improving the speed and reliability of geotechnical investigations. One of the most common in-situ methods in engineering geology and site investigation is Cone Penetration Test (CPT), which is mainly used for characterization of soils, as it is a robust, simple, fast, reliable and economic test that can provide continuous soundings of ...
