PCT No. PCT/NO83/00037 Sec. 371 Date Jun. 5, 1984 Sec. 102(e) Date Jun. 5, 1984 PCT Filed Sep. 9, 1983 PCT Pub. No. WO84/01592 PCT Pub. Date Apr. 26, 1984.An offshore platform structure (1) comprising a deck superstructure (4) which is supported at least by three inclined lower supporting columns (5) which are arranged apart and extend convergingly upwards towards an intermediate structure (6), and one or more upper columns (7), extending upward from the intermediate structure, supporting the deck superstructure. At least the lower supporting columns (5) have varying diameter, the columns having their largest diameter in the area of the towing water line during the towing-out of the platform structure from the construction site. Slipforming means intended for slipforming inclined, hollow columns of reinforced concrete, comprising a slipform platform (14) including the form work (28,29), which is supported by and may be lifted/lowered by means of a climbing rod system (12) which is fixed to the already cast, cured portions of the column (11). The form work is by means of a number of yokes (26,27) suspended from the slipform platform and comprises inner and outer formsheets (28,29 extending in circumferential direction. The yokes are adjustable in radial direction with respect to the slipform platform while the form sheets are adjustable in tangential or circumferential direction with respect to each other. One of the form work walls is radially adjustable with respect to the other. The slipforming means is intended for slipforming hollow, inclined columns having increasing and/or decreasing diameter.
