摘要：The invention relates to a floating structure, e.g. an offshore platform adaptedfor 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 byfootings having buoyancy large enough to keep the platform afloat. Tension wires areextended 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 theportions of the laters between the sea bottom and the points at which the sinkers areprovided may exhibit sags. The sagged portions of the tension wires are expected topresent a buffering effect to diminish the extraordinary large tension in the tension wiresattributable to the movement of the platform. The up and downward movement of theplatform is prevented by a riser pipe extended from the center of the platform. The riserpipe is prevented from being buckled by a provision of a buoyancy body attachedthereto.
