Abstract

A gravity base structure for an offshore platform includes a caisson having a bottom slab, a top slab, and inner and outer concentric walls which extend between the bottom and top slabs, and partition walls that form a lattice structure of triangular prisms between the concentric walls, and a plurality of teeth elements which extend outwardly of the outer wall of the caisson for absorbing the force of iceberg impacts and transmitting such force to the caisson.
