ABSTRACT:
An offshore complex comprises a substantially ring-shaped structure (1) which is intended to rest at its lower end on the sea bottom with the upper end of the complex located above the surface of the water. The structure incorporates water-filled ballast chambers to an extent such that the structure can be caused to float by pumping water from the chambers. The upper ring-shaped end of the structure (1) supports an aircraft take-off and landing strip (3), which rises helically along a part of the perimeter of the ring-shaped structure (1). The area of water (5) enclosed by the ring-shaped structure (1) can be used as a harbor, into which sea-going vessels can enter through an opening (6) provided in the wall of the ring-shaped structure (1) at its upper end. An advantage is gained when the ring-shaped structure (1) is made substantially of concrete, and the structure may incorporate a large number of interconnected, upstanding cylindrical concrete bodies (2).
