For transferring a fluid between at least two floating supports or one floating and one fixed support, a rigid hollow transport line is immersed with a cable suspension system in the sea. A flexible connector links each end of the rigid transport line to one of the supports. The entire rigid transport line including its ends is immersed in the sea at a depth which is greater than the turbulent zone of the sea. Each connector provides continuity of oil flow between the two floating supports via the rigid transport line.

Device for transferring a fluid between at least two floating supports

The invention concerns a flexible tubular pipe comprising, from inside outwards, a web ( ) made of interlocked steel strips, an inner impervious sheath ( ) in polymer material, a short-stepped helical winding of interlocked forming wire ( ) arranged above the internal sheath ( ), at least a hoop ( ) consisting of a short-stepped metal wire winding without interlock, at least a long-stepped tractive armouring layer ( ) wound around the pressure vault and an outer polymer protective and sealing sheath ( ); the sickness (Ef) of the hoop ( ) is greater than the thickness (Ez) of the metal forming wire ( ), preferably by one to three times.

Flexible conduit with high inertia hoop

This one-piece subsea flexible multilayer tubular pipe comprises a carcass ( ) made of interlocked metal strip, an inner sealing sheath ( ) made of a polymer material, a winding of an interlocked metal element ( ) wound in a helix with a short pitch, at least one ply ( ) of tensile armor layers wound with a long pitch around the pressure vault, where appropriate at least one thermal insulation layer ( ) and an outer protective sealing sheath ( ); this pipe has, over its length, sections intended for regions of different use and the physical characteristics of at least one of the layers are modified at manufacture over at least one section of the length of the pipe, without modifying the outside diameter of the said layer, so as to tailor the properties of the pipe in this section to the conditions for the zone in which it will be used.

Subsea flexible pipe of long length and modular structure

A tubular flexible pipe which from the inside outward includes an inner sealing sheath of polymer, a cylindrical pressure vault comprised of a helical wire winding with gaps between the windings, perhaps a wound tensile armoring layer and a scaling outer sheath. The vault includes an elongated masking element, at least partially masking the gaps between the windings of the wire and being at the inner sheath, The masking element is a wire helically coiled in a recess at the inner face of the vault or is an axial extension of the vault wire.

Resistant flexible pipe comprising sealing sleeve with limited creep

A flexible tubular pipe having an internal sheath and a pressure vault around the sheath with a helically would short pitch metal wire. The metal wire has an I-shaped cross-section with a narrowed central web and greater thickness internal and external flanges. Recesses in at least one set of the flanges enable fastening elements to be installed for holding to adjacent wire windings. The ratios of widths of the flanges, height and width of the wire, moments of inertia in the width wise and radial direction are disclosed.
