A floating structure which comprises (a) a plurality of floats, each having a flat, polygonal or irregularly polygonal shape, with the upper and lower half parts staggered horizontally a given distance relative to each other, at least one edge forming an overhanging upper extension and the opposite edge a steplike lower extension, said upper and lower extensions being formed with connecting holes which, when the float is arranged to overlap with floats of the same construction in a mutually complementary manner, come in alignment with connecting holes of the lower and upper extensions of the neighboring floats so that said connecting pins are inserted through the aligned holes, and (b) connecting pins adapted to be fitted into the connecting holes formed in the floats.
A floating platform with motion characteristics for offshore deepwater developments with vertical axial symmetry and decoupling of hydrodynamic design features. A motion-damping skirt (120) is provided around the base of the hull (1), which is configured to provide ease of installation for various umbilicals and risers. A retractable center assembly (300) is used in a lowered position to adjust the center of gravity and metacentric height, reducing wind loads and moments on the structure, providing lateral areas for damping and volume for added mass for roll resistance. The center assembly (300) is used to tune system response in conjunction with the hull damping skirt (120) and fins (121). The center assembly (300) also includes separators (350) below the floating platform deck which serve to add stability to the floating structure by shifting the center of gravity downward, the separators (350) capable of being raised and lowered vertical separators alone or as a unit.
