Abstract

Evaluating physical and mechanical properties of sediments in the marine realm has long been an important scientific and applied challenge. In-situ techniques such as the Cone Penetration Test (CPT) have paved the way for answering many marine geotechnical problems. This paper presents the design and first data example of the Geotechnical Offshore Seabed Tool (GOST) CPT unit. The tool uses a 5 cm2 cone and measures tip resistance, sleeve friction and pore pressure in the u2 position, acceleration and inclination (x,y,z). The primary focus of GOST is offshore investigations in of up to 4000 m water depth but it is also equipped for on-land measurements. GOST can perform static, vibratory penetration, dissipation and remolding tests.
