dotOcean designed an innovative geotechnical profiling system for deep sea waters, the Deep Sea GraviProbe. The system’s cone is lowered in the underwater sediment layer, analyzing those layers during intrusion. Under its own weight it penetrates loose and consolidated mud layers and measuring dynamic tip resistance as a Qc value. The data acquired from the cone, on-board accelerometers, inclinometers and pressure sensors is determining the geotechnical parameters of the intruded medium (Qc over depth and Su over depth). The system is capable of collecting data at 5500 m depths and has a measurement resolution of 100 Pa.
Developed to capture high quality geotechnical profiles of fluid and consolidated mud layers at maximum depth of 5500 meter.
