Abstract

1495932 Offshore platforms SUBMERGED BUOYANT STRUCTURES Ltd 12 Dec 1974 [12 Dec 1973] 57596/73 Heading E1H [Also in Division B7] A marine platform comprises a deck supported on a buoyancy chamber 3 secured to an anchor 9, e.g. a hollow concrete ring or piles, by a multiplicity of cables 8 in two groups attached respectively near the top and bottom of the chamber 3, to restrain the chamber from rising in the water, or moving laterally, or rotating. In Fig. 1 additional buoyancy chambers 6 and 7 can support the platform together with chambers 4 on outriggers 5. The chamber 3 is of generally cylindrical form and has the cables 8 secured to the upper and lower peripheries thereof. In plan the cables are crossed in the manner of a spoked wheel. The chamber 3 and anchor 9 can be formed as hollow reinforced concrete structures which can be used for oil storage. Equipment can be provided for trimming and ballasting the chamber 3. The cables 8 can be formed of steel, or, as in Fig. 8, not shown, of synthetic fibre with steel or iron rings (25) therearound. Mechanisms can be provided for sensing and adjusting the tension in the cables 8. In Fig. 4, not shown, a storage tank (14) is placed on the anchor 9. In Fig. 5, not shown, a storage tank (15) is supported below the chamber 3 on guides so as to be vertically movable. The arrangement of Fig. 6, not shown, has a column (18) in tension between the anchor 9 and chamber 3. In Fig. 7, not shown, a floating oil storage breakwater (19) surrounds the platform 1. The chamber 3 can be of square shape, or hexagonal or octagonal or a frustrum of a torus and can contain air, oil, or expanded plastics.
