1. A process for producing at least one rotating-joint device configured to equip an installation for operating energy, the at least one rotating-joint device having at least one dynamic sealing element housed inside a separating space located between a first annular part that is secured to a stationary mooring turret of said installation and a second annular part that rotates relative to said first annular part and that is secured to a mobile ship of said installation, with at least one among the dynamic sealing element, the first part, and the second part that is obtained from an item blank obtained by implementing the production process which comprises the following steps:
providing at least one strip of a predetermined material;
providing at least one production support that is at least partially annular and that has a predetermined outer diameter;
arranging said at least one strip of a predetermined material around said production support until a predetermined thickness is obtained;
removing the production support to obtain said item blank that has a predetermined cross-section; and
installing the produced item blank in the rotating-joint device of the installation for operating energy.
