A flexible structure of controlled yieldability for use as a hydrocarbon drilling and production platform in deep seas, or as a mooring point for oil tankers, constituted by a foundation base assembly, a vertical cylindrical tubular element placed under tension by a buoyancy chamber disposed at its top in proximity to the water surface, and an overlying lattice which at its top supports the plant platform. The tubular element is connected at its lower end to the base and at its upper end to the buoyancy chamber by means of suitable profiled tapered terminal elements able to withstand the bending loads which are generated at said connections. The entire structure is constituted by four separate pieces, namely the foundation base assembly with the lower terminal element, the lower half of the cylindrical tubular element, the upper half thereof, and the upper buoyancy chamber which is connected at one end to the upper terminal connection element and at the other end to the top lattice. For transportation purposes, these four pieces are assembled telescopically in pairs. On final on-site installation, the telescopic tubular parts are connected together and to the respective profiled terminal elements by mechanical clamps which restore complete structural continuity along the entire axis of the structure.

Slender flexible marina structure for hydrocarbon production and ship

A system for mooring tankers to an emergent fixed structure, constituted by an articulated connection structure using an equalizer hinged to the tanker deck by hinges able to isolate said articulated structure from the tanker rolling motion.

System for mooring tankers to a fixed structure

An apparatus for reducing environmental forces on a mooring system for tanker ships, wherein a fixed structure comprising a hinged arm rotatably movable with respect to the mooring system is provided with a rocker assembly which is pivotally connected to said arm and universally connected via lateral connecting ties to ballast chambers.
