Abstract: A bridge for crossing a passage of a navigation channel includes a section in the form of a single span, which may be displaced by vertical translation between a base position spanning the passage, in which the span rests on fixed support sections of the bridge, and a raised position, for opening the passage, and a support structure for the span on displacement of the span, and a drive for lifting the span. The bridge has only one support structure, with the drive, located on one side of the passage to be spanned.

Abstract: A swivel joint system for a cryogenic liquid transfer line, such as a liquefied natural gas line, and for return of cold gas associated with the cryogenic liquid transfer. The system includes a swivel joint for the passage of the cryogenic liquid and a swivel joint for the return of the cold gas. Each swivel joint includes a conduit with a fixed conduit portion and a rotating conduit portion, rotating relative to the fixed conduit portion, and a rotational guide interposed between the fixed and rotating conduit portions. The swivel joint device for the passage of the gas return is integrated in the swivel joint device for the passage of the cryogenic liquid.

Abstract: The invention relates to a pivotal connecting device of the kind forming a universal Cardan joint coupling in particular for a compliant or articulated column of a sea-bed working structure, said column being pivotally connected to a base member, wherein said universal Cardan joint coupling is associated with one or more rigid connecting ducts for conveying the flow of at least one fluid between said base member and said column.

Abstract: This invention relates to a rotary joint device with multiple piping passages and piping 3,4 eccentric to the axis of rotation X--X of the rotary joint, comprising stationary 1 and rotary 2 portions as well as a coaxial rotary member 7 interposed between the stationary 1 and rotary 2 portions and traversed by conduits 8,9 communicating permanently with the stationary conduits 3a, 4a of pipings 3,4 and with the rotary conduits 3b, 4b of pipings 3,4 through a connecting path 10,11.
