A buoyancy element (6, 7) for releasable connection to a structure (1) floating in a body of water (W) is characterized by a lower support element (19) and compartments (11 -14) fluidly interconnected via openings (60). One of said compartments is a central compartment (11) which via a control means (11b) and a duct (11a) is selectively fluidly connected with water surrounding the buoyancy element, whereby the buoyancy element (6, 7) is connected to the structure (1) only by means of the hydrostatic pressure exerted by the water onto the buoyancy element (6, 7). A device (8) for increasing the buoyancy and stability of a structure (1) floating in a body of water (W), for releasable connection to said structure is characterized by a wall (24a, 24b) encircling a portion (2a) of the structure and extending upwards from a support region (3; 30) on the structure to a distance above the water and thereby defining a compartment (25) between the wall section and the portion of the structure, whereby the water plane area and buoyancy for the combined device and structure are enhanced. A buoyant compounded structure, capable of being transported in a semi- submersible state in a body of water, comprises a plurality of buoyant individual structures (l a-c) having respective individual water plane areas and connection means (30; 31, 30a-c, 33) and abutment regions (9, 34, 35, 34', 35 '). The connection means are releasably connected between each of said individual structures at a vertical distance from said abutment regions, whereby the compounded structure comprises one, substantially rigid, body having a floating stability which is better than the floating stability of the individual structures when such individual structures are disconnected from each other. |
