Abstract
Semi-submersible platform structures for drilling for natural resources in pelagic areas may be equipped with so much fixed equipment at deck level that their stability becomes insufficient. In order to improve the stability, such a platform is provided with one or more stabilizing elements (6) which are placed aft on the platform. The stabilizing element (6) extends between a submerged buoyancy body (1) of the platform and its deck (4) and has a constant cross-section up to the deck (4). For example, it can comprise a cylinder (7) with a tapering lower portion (9). The connection between the lower portion (9) of the element (6) and the buoyancy body (1) can have a connection (13) which is arranged to rupture before the buoyancy body can be damaged should the stabilizing element (6) be subjected to strong collision forces. The stabilizing element (6) can be connected at the top to the deck (4) of the structure by means of a connecting link (8) which permits a certain resilient rotation about horizontal axes. <IMAGE>
