<p>A buoyancy device to be clamped around at least one longitudinal element (8). The buoyancy device (1) comprises an assembled clamping device (2, 3, 4, 5, 6, 7) which is to be fastened around the element (8), and at least one buoyancy member (9, 10) connected to the clamping device (2, 3, 4, 5, 6, 7). The buoyancy member (9, 10) is divided longitudinally in at least two sections and is arranged around the element (8) together with the clamping device (2, 3, 4, 5, 6, 7). The buoyancy member (9, 10) is divided in at least tow separate or jointly pivoted buoyancy segments (9 resp. 10) which may be folded around the element(s) (8) and loosely enclose a part of this (these). The clamping device (2, 3, 4, 5, 6, 7) is divided in at least two separate, or hinged together, clamping segments (11, 12), adapted to be folded around the element(s) (8), preferably in a firm and prestressed manner. The buoyancy segments (9, 10) are mechanically interconnected by at least one of the clamping segments (11, 12) by means of radially extending, complementary designed parts (16, 4) of the buoyancy segment (9, 10), and the clamping device (11, 12) respectively; so that the clamping devices (11, 12) and the buoyancy devices (9, 10) are interconnected to an integrated buoyancy device (1), by means of at least one peripheral tension element (5) which is slidably fastened at fastening points (3), farthest out on the radially extending parts of the clamping segments (11, 12), without stressing the buoyancy members (9, 10).</p> |
