1. An offshore floating tower comprisinga vertical cylindrical external enclosure divided by a horizontal slab into two open-ended half-cylinders;
- a lower half-cylinder comprising a ring of buoyancy tanks enclosing a bell-shaped chamber partially filled with air and producing partially pneumatic damping movement of the tower, and being ballasted to the required extent; and
an upper half-cylinder open to the sea with its entire surface comprising a regular pattern of perforations;
said tower including a vertical cylindrical internal enclosure coaxial with the vertical cylindrical exterior enclosure, constituted in the upper half-cylinder, an annular damper chamber and, in the lower half-cylinder, a bulkhead separating the bell-shaped chamber from the ring of buoyancy tanks which are separated from the sea by a bulkhead consisting of the external cylindrical enclosure.

Abstract
An offshore floating tower comprises two coaxial cylindrical enclosures (2 and 11) interconnected by continuous radial bulkheads (10) forming in the upper portion a ring of damping chambers (12) and in the lower portion a ring of buoyancy tanks (4) around a bell-shaped chamber (5) which is partially filled with air to produce pneumatic damping of vertical movement of the tower. The upper portion of the tower is separated from the lower portion by a horizontal slab (3). The upper portion of the internal enclosure is perforated in the vicinity of the horizontal slab.
