Abstract
An offshore platform includes a buoyant hull comprising three or more interconnected pontoons and a plurality of support columns. The support columns support a deck or structure that supports equipment and/or payloads above a water surface. The support columns extend upwardly from respective ends of the pontoons to the deck or structure supported above the water surface. Anchoring members anchor the platform to the seabed.

A buoyant hull for supporting an offshore platform above a water surface, said hull comprising:
- a) a base node;
- b) at least four pontoons extending outwardly from said base node at right angles to each other;
- and
- c) upwardly extending support columns fixedly secured proximate a distal end of each of said pontoons.
An offshore floating platform, comprising:
- a) a buoyant hull, said hull including three or more support columns interconnected by pontoons having a proximal end and a distal end, each of said support columns having an upper end and a lower end;
- b) a deck supported above a water surface on said upper ends of said support columns;
- c) wherein said support columns are battered inwardly toward a center vertical axis of said hull and extend upwardly from proximate said distal ends of said pontoons to said deck;
- and
- d) one or more anchoring members having one end connected to said hull and an opposite end anchored to the seabed.
An offshore floating platform, comprising:
- a) a buoyant hull, said hull including horizontally disposed pontoons intersecting at angles between 60 to 120 degrees to each other, said pontoons having proximal and distal ends;
- b) upwardly extending support columns fixedly secured proximate said distal ends of said pontoons;
- c) a deck supported above a water surface by said support columns;
- and
- d) one or more anchoring members having one end connected to said hull and an opposite end anchored to the seabed.
