Abstract: A rotary joint device of an installation for exploiting energy includes a first annular part that is secured to a fixed mooring turret of the installation, a second annular part rotatably movable about an axis of rotation and in relation to the first fixed annular part and that is secured to a movable ship of the installation, and at least one dynamic sealing member housed inside a gap space located between the first fixed annular part and the second movable annular part and provided with a body portion and with at least one first lip that projects from the body portion. Also described is an energy exploitation installation including such a rotary joint device.

Abstract: Disclosed is a process for producing a blank from an item that is configured to equip a rotating-joint device of an installation for mining fluids, in particular on an offshore platform, including 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 the at least one strip of a predetermined material around the production support until a predetermined thickness is obtained; and removing the production support to obtain the item blank that has a predetermined cross-section.

Abstract: An electrical connection assembly (70, FIGS. 4-7) connects a cable conductor (82) of stiff material such as a copper wire, to a deformable electrode (34, FIG. 5) that lies at the surface of a sheet of elastomeric material (74). The connector assembly includes deflectable elastomeric walls that form a cavity (76) that holds an electrically conductive fluid (84) such as an electrolyte that surrounds and engages the stiff conductor (82) and that engages the elastic electrode (34) as it deflects.
