Abstract (en)
This invention relates to a method of, and apparatus for, placing a platform on a support structure which, on the one hand, is anchored in the bottom under a body of water surrounding the support structure, in particular in high seas, and, on the other hand, extends to above the water surface. Use is made of a semi-submersible vessel capable of being moved between and/or around the support structure and moored in a position in which the platform is roughly in proper position relative to the support structure. The platform is then arranged to be movable relatively to the vessel in a horizontal plane with relatively light forces by releasing locking means and activating means suitable for the purpose, and accurately positioned relatively to the support structure by automatic steering and correcting means. Thereafter the vessel is submerged until the platform is placed on the support structure.
