1 de jun. de 2020 · Free Fall Penetrometer (FFP) testing consist of a torpedo-shaped body freefalling into a soil target. The use of this type of device is becoming popular for the characterization of shallow sediments in near-shore and off-shore environments because it is a fast, versatile, and non-expensive test capable of recording acceleration and ...

12 de mar. de 2024 · Underwater free fall penetrometers (FFP) are increasingly used in nearshore and offshore geotechnical site investigations [4, 55, 83, 103, 104]. In recent decades, a variety of FFPs with different sizes, shapes, and instrumentation have been developed and tested in the field and laboratory [ 46 , 97 ].
29 de may. de 2013 · Abstract. This paper presents the results of a series of laboratory model free-falling penetrometer (FFP) tests in kaolin clay. A thin-shafted FFP has been allowed to free fall and has also been pushed at a relatively slow constant rate into clay beds.
Free fall penetrometers (FFP) can improve the efficiency of deepwater geotechnical site investigations. This study investigates the derivation of geotechnical properties from piezocone FFP measurements in the upper 4 m of the seabed at a clayey site with water depths of ∼1500 m.
21 de mar. de 2019 · Free fall penetrometers (FFP) are designed to address this need, and to facilitate geotechnical in situ testing in subaqueous areas in a cost-effective manner. Soil parameters are deduced from different sensor suites, and in the case of small-scale, portable devices, often using only acceleration sensors and a pore pressure transducer.
