Abstract

Abstract A floating platform having a plurality of float units which are interconnected together in end to end relation with their top surface portions being substantially flush with each other, each of the interconnected units having a predetermined buoyancy which is sufficient to float the platform in a flotation medium, such as water, wherein at least two of the units have a different relative predetermined buoyancy with respect to each other and the flotation medium prior to external loading thereof. The platform is arched along at least a predetermined portion of its length prior to external loading thereof. The arched portion may be either convex or concave or a combination thereof, depending on the relative buoyancy of the interconnected units and the intended use of the platform. Furthermore, if desired, the buoyancy of the various units may be chosen so as to float the platform below the surface of the flotation medium or to float the platform with at least a portion thereof above the surface of the flotation medium. The units are preferably interconnected by means of tension elements, such as rods or cables which are posttensioned during the assembly of the platform. A floating platform may also be formed from a plurality of such float units which are interconnected together in side to side relation with their top surface portions being substantially flush with each other, in addition to having the units interconnected together in end to end relation. The relative buoyancies of the side to side interconnected units may also be different so as to provide a side to side arched portion as well as an end to end arched portion for the complete structure, or any combination thereof. The units are preferably interconnected in side to side relation by transverse tension elements in the same manner as the longitudinal end to end interconnections.
