A UNIVERSAL FOOTING WITH JETTING

This paper presents a footing technology that uses a novel internal jetting system to quickly install jackup footings on any type of seafloor. A universal footing consists of three parts: (1) a solid cone spike (to support footing on hard soils, coral or rock), (2) a hollow spud can (for support on soft clayey soils), and (3) an internal jetting system (to assist with penetration and removal on sandy/silty soils). The footing technology is one of many technologies that are being developed at the Naval Civil Engineering Laboratory for the US Navy's Advanced Cargo Transfer Facilities (ACTF) sponsored by the Naval Facilities Engineering Command.
