Device and process for making penetrate into the seabed, in particular at great depths in excess of 1000 meters.A tool for collection of soil samples or measure of caracteru00ecsticas this soil ".The invention relates to a device to penetrate into the seabed, in particular at great depths in excess of 1000 meters.A tool for collection of soil samples and measure the characteristics of the soil.According to the invention the tubular tool (1) that you want to do penetrate the seabed is fixed to a base plate for positioning on the sea bottom.And the device comprises at least one hydraulic jack (16) which can be actuated from the surface.It is fixed to the base plate comprising a piston (4) which moves in an annular cylindrical chamber (3) directed parallel to the shaft axis (y 'y) of penetration of the tool (1),Engaging the tool (1) in the light of the evacuation or admission of fluid that is held in said chamber (3),The said piston (4) being subjected to hydrostatic pressure prevailing in the depth of up to where it was lowered the device being placed in communication with the marine environment from its external side to the actual cu00e2maRa (3).
