ABSTRACT:
An offshore double cone structure for operation on an ocean foundation has a double-cone concrete shell having a neck ring at the top of the shell and a base caisson that supports the double-cone shell. The caisson rests on the ocean foundation. The environmental loads, topside weight, and self weight of the double-cone shell are transferred by double-cone shell action through the base caisson to the foundation. The base caisson's exterior wall can be either vertical or sloping. The neck ring is at an elevation sufficiently high that the wave and ice interactions with the neck ring do not increase global ice loads acting on the structure. The neck ring has sufficient area to provide room for facilities through the neck.
