A method of installing and implementing a rigid tube () 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 () on the surface () to below sea level () to be connected to undersea equipment () that is immersed (); and b) maintaining the main tube as immersed in this way for a given period of time. The said main tube () is caused to pass through a cylindrical orifice () of circular section in a stress limiter device, the orifice having a slippery internal coating () secured to a support structure () 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).

Method for installation and implementation of a rigid tube from a ship or floating support

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.

Device for transferring fluid from a marine mounting

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.
