... analysis and correction, considering the high penetration rates involved. The FFCPT is an acceleration-based system, that is robust enough to survive impact on a hard seafloor. Whilst the FFCPT will not replace existing cone penetration test (CPT) methods, it can yield reliable supplementary data...

... penetration rate of the cone probe. Therefore, application of FFP observations to geotechnical parameters estimation requires a strain-rate correction according to some strain-rate laws. The commonly employed procedure requires matched (i.e., closely located in space and time) quasi-static and FFP...

... with this paper is to introduce an approximate method for determining the soil stiffness of sand regarding large-diameter monopiles by modifying the initial stiffness of the API p-y formulation. The modification introduces both a stress level and a strain level correction derived on basis of sound theoretical...

... as for the piezocone) results in nearly equal overburden stress above and below the penetrometer body, reducing the overburden correction to 10% of the correc- tion required for the piezocone (CPTu). The correction for the imbalance of overburden stress on measured penetration was initially assumed to be insignificant...
