Abstract
A readily portable seabed penetration system for conducting cone penetrometer tests or the like from a support disposed above the water over the portion of the seabed to be penetrated. The system includes a casing string connected at its upper end to the support and at its lower end to a suction anchor. A string of push rods encased within the casing string is provided at its lower end with a penetrometer cone. With the suction anchor evacuated, the lower end of the casing is securely anchored to the seabed. Upward tension is then applied to the casing while downward force is applied to the rod string to drive the penetrometer cone into the seabed. The rod string is supported against buckling by the tensioned casing string.
