The invention relates to an arrangement in an offshore platform (1a), comprising a deck structure (1) which is supported above the water surface (5) by means of a column structure (14, 2) which in turn rests on and is connected to a foundation (3) on the sea bottom (4). In order to provide a compliant platform structure which is not dependent upon guylines preventing free traffic around and at the platform (1a), the column structure (14, 2) comprises at least one hollow column (2), in the cavity (2a) of which there is provided at least one tension means (7) which at its first end is connected to the foundation (3), and which at the second end is connected to the column (2). The foundation (3) can be preinstalled at the sea bottom (4), or might constitute a part of the offshore platform (1a) such that the latter mounted on the sea bed (4) as a gathered unit.
