Abstract
A floating marine platform is provided including a central column, at least three peripheral columns circumferentially around the central column, radially extending beams from the central column that connect the peripheral columns with the central column, and structural members spanning between each adjacent pair of peripheral columns. The structural members are pre-tensioned.
Claims18
A floating marine platform comprising:
- a central column;
- at least three peripheral columns circumferentially around the central column;
- and
- beams radially extending from the central column that connect the peripheral columns with the central column,
- wherein the beams are steel hollow cylindrical pipes,
- wherein the peripheral columns comprise a buoyancy air chamber, and
- wherein the marine platform comprises a motion control system comprising a pressurized air tank discharging air in the buoyancy air chamber, which controls airflow in and out of the buoyancy air chambers using actuated valves and is controlled by a computer system that is coupled with motion sensors, and
- wherein the pressurized air tank is formed by an airtight inside volume of one of the beams,
- wherein the floating marine platform further comprises structural members spanning between each adjacent pair of peripheral columns,
- wherein the structural members are pre-tensioned and comprise or are formed with a steel tube,
- wherein the peripheral columns comprise a connector having a passage for one end of each of the structural members, and
- wherein each of the structural members comprises a tension head at an end of the steel tube that is received in the connector, and the steel tube of each of the structural members extends through the passage as from the tension head.
