A method of installing an offshore construction, includes fabricating platform support columns (30) from a plurality of interconnected column sections (40). The method comprises placing a first column section at the surface of a body of water, at least partly submerging the first column section by a certain amount, placing a second column section on top of the first column section whereby the top of the first column section is joined to the bottom of the second section near the waters' surface, the second column section thereafter being at least partly submerged as was the first column section. Additional column sections are placed on top of and joined to successive partly submerged column sections near the waters' surface, until a finished column of desired height is formed by the joined column sections. A base (10) may be initially connected to the bottom of the first column section. The finished column may then be anchored to the seabed with guys (34) to maintain the finished column in a fixed vertical position. After a number of columns are formed, they may be braced together with braces (32) and the individual anchoring can be removed. The column can be disassembled and the column sections can be re-used. |
