Abstract
Apparatus for connecting at least one pipe-line situated on a sea-bed to a floating or semi-submersible platform which includes a vertical pipe-line section consisting of at least one flexible pipe arranged between a sinker resting on the sea-floor and an air-tank submerged at a sufficient depth to be protected from the action of the swell, the buoyancy of the air-tank being such that it maintains the flexible pipe section vertically under tension, the lower portion of the pipe-line of the section being connected to the pipe-line or lines situated on the sea-bed, while the upper end pipe-line of the section is connected to the submerged body of the platform by at least one additional pipe-line which is flexible along at least certain of its portions.
