Abstract

A structure for use in supporting a platform (13'') above a body of water. The structure includes a leg (21) extending between the bed of the body of water (345), the seabed (39), and the platform. The overall cross-sectional area of the leg is greatest near the seabed and decreases moving upwardly away from the seabed.
