Abstract: A method of installing and implementing a rigid tube (10) referred to as a “main” tube, wherein the following steps are performed: a) lowering an end of the main tube from a floating support or vessel (13) on the surface (14) to below sea level (14) to be connected to undersea equipment (16) that is immersed (17); and b) maintaining the main tube as immersed in this way for a given period of time. The said main tube (10) is caused to pass through a cylindrical orifice (4) of circular section in a stress limiter device, the orifice having a slippery internal coating (3) secured to a support structure (9) secured to the floating support or vessel, the service tube thus being suitable for sliding in contact against the slippery coating during steps a) and b).

Abstract: A device for transferring fluid from a support installed at sea and fitted with a device for storing flexible pipes having the first ends of a plurality of flexible pipes fastened thereto, the pipes preferably extending between said support and an offloading ship. The pipe device having a first connection and valve device, the pipes being connected to one another at their seconds ends by a the first connection and valve device having n first pipe portions and suitable for being connected to a second connection and valve device, preferably installed on board an offloading ship.

Abstract: A support installed at sea and fitted with a storage and guide device for storing and guiding flexible pipes, the support has a first carrier structure supporting a plurality of turntables arranged one above another, flexible pipes being wound in concentric juxtaposed spiral turns of increasing diameter resting on said turntables, a rotary joint enabling coupling to be established between (1) a first end closest to the center of the turntable of a flexible pipe on said turntable, and (2) an end of a transfer pipe that remains stationary while said turntable is being driven in rotation; a plurality of guides suitable for guiding portions of the flexible pipe outside the turntables.
