Abstract
The invention relates to a floating structure, e.g. an offshore platform adapted for use in exploitation of submerged oil fields and the like purposes at offshore areas. The structure has a platform from which extended downwardly are columns carried by footings having buoyancy large enough to keep the platform afloat. Tension wires are extended through the footings for connection to the sea bottom in a diverging manner. Sinkers are provided at intermediate portions of respective tension wires so that the portions of the laters between the sea bottom and the points at which the sinkers are provided may exhibit sags. The sagged portions of the tension wires are expected to present a buffering effect to diminish the extraordinary large tension in the tension wires attributable to the movement of the platform. The up and downward movement of the platform is prevented by a riser pipe extended from the center of the platform. The riser pipe is prevented from being buckled by a provision of a buoyancy body attached thereto.
