- Floating stand equipped with drum with bearings running out of water.
- the present invention relates to a floating support anchored on a disconnectable drum.
- the technical sector of the invention is more particularly the field of underwater oil production in extreme weather-ocean weather zone and more particularly in the Arctic and Antarctic, from floating supports.
- a floating support for oil production generally includes anchoring means to remain in position despite the effects of currents, winds and waves. It also generally comprises means for drilling, storage and treatment of oil and means of unloading to removing tankers, the latter occurring at regular intervals to perform the removal of production.
- the usual name of these floating supports or vessels is the Anglo-Saxon term “Floating Production Storage Offloading" (meaning
- the FPSO When the ocean-weather conditions, ie swell, wind and current are important, even extreme, in the case of storms, it is preferable to anchor the FPSO at a reel, usually located at known manner in the forward third of the ship and in the axis, the ship being free to turn around said drum in the wind, the current and the swell.
- wind, current and waves exert specific forces on the hull and the superstructures, the FPSO because of its degree of freedom of rotation around the vertical axis ZZ, coming naturally to the position of least resistance.
- the pipes connecting the wellheads are generally connected on the underside of the drum and connected to the FPSO via a rotary joint integrated in the axis of said drum.
- weather conditions can become extreme, such as in the North Sea, in the Gulf of Mexico or in the Arctic or Antarctic zone, the FPSO is generally disconnectable so that it can be sheltered waiting for acceptable operational conditions.

- the floating supports advantageously have a hull with longitudinal edges substantially vertical to give them optimum oil storage capacity, and better behavior in case of high sea. But a hull with vertical edges is particularly disadvantageous in terms of behavior. facing the pack ice.
- floating supports are proposed which, inter alia, have curved or angled curved planks to promote ice breakage, as is the case with the known ship bow profiles with bow inclined to the horizontal.

- a safety device is advantageously added so as to avoid the downward fall of the external structure 2c, in case, for example , invasion of the drum by the water following a valve rupture or a leak in the sealed structure of said outer structure 2b.
- a series of stops and latches 2di-2d 2 arranged in a circular manner between said external structure and said internal structure prevents said external structure from falling down in case of invasion.
- a stop 2di is fixed on the structure of the outer portion 2b, while the latch 2d 2 is movable in horizontal translation and disposed within the internal structure 2a below the corresponding stop 2di.
- Said latch 2d 2 is shown in the retracted position on the left part of FIG. 2A, and in the extended position of retaining the abutment 2di on the right side of Figure 2A when the outer structure 2b has a tendency to flow.
- a similar latch is advantageously used to block the rotation of the drum during maintenance operations.
- FIGS. 3A and 3B show a bearing structure in the form of a central shaft with a circular section 6 resting on the bottom 2c of the outer structure 2b of the drum and serving both to support the pipes 14 passing through the cavity 4 to join the rotary joint connection 3, and supporting the rotating joint connection 3 itself at its top, substantially at the level of the floating support deck 10.
- the invention has been described with a support bearing 5i located between the bottom of the internal structure 2a and the bottom of the sealed outer structure 2c, but according to a variant of the invention, said support bearing is located at the level of the top the sealed outer structure 2b, between the latter and the internal structure, at the underside of the peripheral plate 2ai.
