The invention relates to an undersea connector for connecting an oil installation to the sea bottom, the connector being of the type presenting a first tubular element forming a female portion for fastening to the ocean bottom and a second tubular element forming a male portion for connection to the oil installation, wherein the connector comprises at least one anti-disconnection device for the connector, the device being housed in the female portion and comprising means for positioning the device in a first position in which the connector is capable of being disconnected, or else in a second position in which the connector cannot be disconnected.

Undersea connector for connecting an oil installation, the connector being provided with an anti-disconnection device

A connection device for connecting a submerged tubular structure to a floating support structure. The connection device includes first and second tubular connection elements that connect the submerged tubular structure to the floating support structure. The first tubular connection element cooperates with the second tubular connection element to form a first axial abutment in a pulling direction in which the submerged tubular structure is pulled, and a second axial abutment in a direction opposite from the pulling direction. The device further includes a locking and tensioning device that includes at least one actuator secured to the floating support structure and is mounted to pivot on the second tubular connection element about a hinge axis and against the effect of a return spring surrounding the pin so as to enable the first tubular connection element to snap-fasten onto the second tubular connection element.

Device for connecting a submerged fluid-transporting line

The invention relates to a steering device for a vehicle bogey fitted with wheels having pneumatic tires that run on a pair of runways forming a track along which the vehicle travels. The device comprises a steering caster whose mean plane is parallel or substantially parallel to that of the wheels of the bogey and which is capable of rotating about its own axis when engaging in a guide groove installed between the above-mentioned runways of the track ahead of each branch point. The caster is carried by the frame of the bogey via laminated link blocks that confer to the caster and relative to the bogey a small amplitude degree of freedom in rotation about a vertical axis passing through the center of the caster, and a similarly small amplitude degree of freedom in translation along the axis of the caster, but prevent the caster from moving relative to the bogey in the vertical direction.
