Embodiment Construction

[0103] Figure 1A It is a side view of the floating support 1 of the FPSO type 1-1 of the present invention anchored 1a in a gas producing field in the open sea.

[0104] The FPSO has equipment 1b for processing and liquefying gas together with a first tank 11 integrated inside the hull for storing LNG.

[0105] The methane tanker type unloading vessel 2 is positioned approximately in tandem on the axis of the FPSO and is connected to the FPSO by a set of three flexible pipes 3A, 3B and 3C with the aid of means for positioning and guiding the flexible pipe 3 The positioning and guiding device 4 of the present invention is handled, which device is described in more detail below.

[0106] Said flexible pipe 3 is a floating flexible pipe type manufactured and marketed by the French supplier Trelleborg, mainly consisting of metal or composite reinforcements together with thermoplastic or vulcanized elastomers.

[0107] Such pipes for unloading and transporting liquefied gas gener...

Abstract

The present invention relates to a support structure (1) installed at sea and provided with a device (4) for storing and guiding hoses (3, 3a-3b-3c), comprising: a first load-bearing structure (5) supporting a plurality of turntables (4-1) arranged one above the other, wherein hoses are wound or capable of being wound into concentric adjacent spirals having increasingly larger diameters and resting on said turntables; a rotary seal (7) connecting a first end (3-1), closer to the center of the turntable, of a hose pipe on said turntable, to an end (8-1) of a transfer pipe (8) which remains stationary while said turntable is rotated; and a plurality of guide means (10, 10a, 10b, 10c), capable of guiding portions (3-2) of said hoses on the outside (3-2) of said turntables that form a continuation of the remaining portions of the hoses resting on said turntable, such that said hose portions (3-2) exiting said turntables are rectilinearly arranged at different positions in a horizontal direction (Y1Y'1) parallel to said edge and at different heights, and such that the vertical axial planes P1, P2, P3, relative to said horizontal direction (Y1Y'1) parallel to said edge (1d), of said hose portions can have various angles (a1, a2, a3).

Description

technical field [0001] The invention relates to a support mounted offshore, i.e. rested or anchored respectively to the seabed, in a grounded or floating manner, the surface of which support is equipped with equipment for positioning and guiding a flexible pipe, suitable for positioning and guiding a plurality of (preferably at least three) of said flexible pipes for transporting petroleum fluids at sea. [0002] The installation and guiding device of the flexible pipe provided on the support of the present invention is used to handle the flexible pipe in order to place the flexible pipe in a coiled state between two fluid transfers in the flexible pipe between the floating support and the unloading vessel. pipe and for deploying said pipe for performing said fluid transfer between said floating support and said vessel, said vessel preferably being of the methane tanker type. [0003] A more specific technical field of use of the stent of the invention is that of unloading pe...
