Semi-submersible platform

摘要

An uncrossed-braced, column stabilized semi-submersible and improved methods of operation of the same are disclosed. The semi-submersible vessel provides necessary strength to resist hydrodynamic forces via a unitized support system. Improved elliptically shaped columns (23, 24, 31, 32), haunch supports (25, 26, 33, 34) and reinforcing members (54, 55, 56) provide stability and resist transverse forces. A skirt (72) design minimizes the reduced stability at the transition point Improved deck (28, 29) designs reduce environmental impacts and provide additional support against transverse forces. <IMAGE>
