Measures mud densities between 1.0 T/m³ and 1.5 T/m³ with an accuracy of 0.25%. The technology is based on X-ray and is a direct measurement method. With a sampling speed of 10 Hz, the system supports fast profiling. The X-ray technology does not suffer from strong legislation restrictions like radioactive density measurement systems. The system weighs 70kg and is able to deeply intrude into soft sediment layers.
of density profile, depth, inclination, winch speed and cable tension
Along with the DensX comes a user friendly software that controls a fully automated winch. The software visualizes the density profile, the winch speed, the winch torque and the tilt of the DensX. When several density profiles are taken, the software generates a mud grid and interpolated dredging volume.
The GraviProbe is a free fall impact instrument, characterising the underwater sediment layers during intrusion. Under its own weight it accelerates and penetrates fluid and consolidated sediment layers. The GraviProbe is able to very accurately measure the thickness of the fluid mud and consolidated mud layers, even in gassy environments.
Rheology, Soil and DINO version for every type of soil
The data acquired from on-board accelerometers and pressure sensors is feeding a dynamical model which determines the geotechnical parameters of the intruded soil (depth, undrained shear strength (dynamic and static Su) and dynamic cone penetration resistance).
