Definitions

  • 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 ships is the Anglo-Saxon term “Floating Production Storage Offloading” (meaning “floating medium of storage, production and unloading") which one will use the abbreviated term "FPSO” as a whole of the following description, or "FDPU” or “Floating Drilling & Production Unit” (meaning “floating means of drilling and production”), when the floating support is also used to carry out drilling operations with deviated wells in the height of the slice of water.
  • 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 vessel 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 present invention relates more particularly to a floating support for submarine oil production in the Arctic or Antarctic zone equipped below its hull with a disconnectable drum from which anchor lines extend to the seabed and pipes.
  • bottom-surface connection link said hull having in its longitudinal direction substantially plane and vertical side edges, and possibly, with, in known manner, the prows (front part of the ship) and, preferably stern (rear part of the ship), inclined relative to the horizontal and preferably profiled to form a reinforced pointed bow, capable of breaking the pack ice by simple bending when said pack ice engages force under said reinforced bow.
  • 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 which, among other means, have curved or angled curved planks to promote ice breakage, as is the case with the known bow ship profiles with bow inclined relative to the horizontal.
  • the rolling bearing is either located at the level of the floating support bridge or located in the lower part in a wet zone, that is to say that the bearing is immersed, or else in combination of the two previous configurations.
  • Embodiments in which the rolling bearing is located exclusively at the level of the bridge are valid only for floating supports of relatively low height, especially less than 15 m. Beyond that, for the floating supports, in particular of 20 to 25 m high, the horizontal force on the drum resulting from the rotation of the floating support creates a bending on the structure of the drum in its length, which stresses the mechanical resistance of the bearing higher rolling and therefore affects the mechanical reliability of operation. On the other hand, when the rolling bearing is immersed in the lower part of the drum, this immersion affects the reliability of operation and durability of said rolling bearing and in addition creates difficulties in carrying out maintenance operations.
  • the object of the present invention is to provide a new type of floating support defined above with disconnectable mooring system comprising an improved rotary drum, more particularly whose reliability and maintenance of the rolling bearings used to make the reel rotary relative to the floating support is improved, especially simpler and less expensive to achieve and implement.
  • This arrangement of the mooring system and the rolling or friction bearing according to the present invention is particularly advantageous with respect to the prior art, since said rolling bearing is dry, and accessible from the inside of the internal structure and / or external structure without having to work in submerged conditions, both for the intervention personnel and for the equipment.
  • Rolling means for example, can thus be easily maintained, in particular lubricated regularly, which drastically reduces friction and facilitates the rotation of the FPSO on its drum.
  • the rolling elements can be easily changed in all conditions, especially in storms and not only in calm weather.
  • said floating support comprises at least one lower rolling bearing said support interposed between the bottom wall of said tubular outer tubular structure and the lower end of said internal structure.
  • said rolling bearing is located above said bottom of the drum and below said internal structure.
  • said internal structure consists of a tubular structure of circular section at its lower end, said bearing is interposed between said bottom of the outer structure and the circular edge of the lower end circular section of said structure internal.
  • said bearing (s) is (are) constituted by rollers or rollers.
  • rollers or rollers are arranged with their axes of rotation in a substantially vertical position interposed between said internal structure and external structure in the case of said lower and upper lateral guide bearings; and, in the case of said lower support bearing, said rollers or rollers are arranged with their axis of rotation in a substantially horizontal position.
  • said guide rollers or rollers are arranged circularly around said internal structure, preferably evenly spaced in the annular space between said inner structure and outer structure, circularly, preferably evenly spaced on said bottom of the outer structure disposed in circle.

  • said upper plate is supported at a redan at the upper end of said cavity, preferably so that the upper plate does not exceed the height of the bridge of the floating support.
  • said internal structure encloses a bearing structure, preferably in the form of a central shaft, preferably of circular section, resting on said bottom wall of said outer structure, being tubular and extending to the level of the floating support bridge.
  • said support structure now in position supporting said second conduits passing through the inner structure, and said rotary joint fitting resting over said supporting structure at the deck of the floating support.
  • said buoy comprises an upper tubular wall, preferably of circular section, delimiting a so-called chamber chamber valves when the upper edge of the tubular upper wall of the buoy is applied against the bottom wall of the drum, said valve chamber enclosing the upper ends of said first pipes passing through the bottom wall of said valve chamber, the upper ends of said first pipes being equipped with valves and / or male or female automatic connector part, supported by said bottom wall of the valve chamber, and said buoy having in the lower part an annular box constituting a float on the underside of the bottom wall of the chamber of the valves valves.
  • an FPSO type floating vessel or support 10 anchored on a 1,2,3 disconnectable mooring system drum anchored by anchor lines 13 and connected to wellheads under -marines, not shown, by flexible pipes 14 in the form of plunging chain 14a to a subsurface float 15 supporting said hose, said float being held by a cable 15a connected to a dead body 15b at the bottom of the sea, then said flexible pipe 14a is extended in chain configuration 14b to the bottom of the sea 40, then to said wellheads.
  • the FPSO is in cold waters in which icebergs or large, large ice sheets floating on the surface of the sea can move. 32 In extreme situations, such as storms or in the case of sea ice.
  • the lower part 1 of the mooring system commonly called “spider buoy”, that is to say “spider buoy” is in fact an annular mooring buoy 1 which can be disconnected, so known to those skilled in the art, generally at the bottom of the FPSO, which allows to release said FPSO so that it can get away.
  • the mooring buoy 1 and the first submerged lines 14 are connected to said bottom wall 2c of the drum on the underside of the bottom wall 2c by automatic connectors 7.
  • the internal buoyancy of the ring buoy mooring 1 being adjusted in such a way that said buoy stabilizes at a depth H above the seabed, corresponding for example to a distance of 100 m from the surface of the sea 32, thereby putting all the lines anchorage and hoses at the shelter, as shown on the same figure 1 .
  • the second conduits 14c pass through the bottom wall 2c of the drum from a female part 7b of automatic connector on the underside of the bottom wall 2c at the lower end of the second pipes.
  • These female portions 7b of automatic connector cooperate with male portions 7a of automatic connector at the upper end of the first conduits 14 supported and moored to said buoy 1, thus allowing the connection of the first and second lines.
  • the upper part of the mooring buoy 1 is constituted by an upper tubular wall 1a, preferably of circular section, delimiting a chamber 30 enclosing the upper ends of the first conduits 14 passing through the bottom 30a of the chamber 30, said upper ends of the first ducts 14 and lower ends of the second ducts 14c being equipped with valves 8a and 8b respectively and male part 7a and female part 7b of automatic connectors 7.

  • the mooring buoy 1 comprises a lower portion 1c forming an annular box constituting a float on the underside of the bottom wall 30a of the chamber 30 of the valves.
  • the rotary joint connection 3 is articulated freely in rotation, so as to allow the rotation of said floating support without causing the rotation of said coupling and the pipes which are connected to it at the level of the floating support.

  • the drum 2 is installed in a cavity 4, preferably circular, vertically traversing the FPSO 10 over its entire height, from the deck 1 to the bottom of its hull.
  • the upper part of the cavity 4 has a redan 10a at the upper part 2a 1 of the drum. Seawater is present inside said cavity 4 of the FPSO and the drum naturally floats in said cavity because the buoyancy is exerted on an external structure 2b of the drum 2.
  • guide and support bearings consisting of rollers in contact, on one side with the outer structure 2b, and on the other with the internal structure 2a, but it will be advantageous to use casters rotating about an axis, said casters being in direct contact with one of the structures, for example the external structure 2b, the support of the axis of said caster being integral with the opposite structure, therefore of the internal structure 2a .
  • Said bearings 5 1 , 5 2 , 5 3 are friction or rolling bearings, preferably rolling bearings.

  • the tubular internal and external tubular structures have a substantially vertical axis of rotation ZZ, thanks to the lateral guide bearings 5 2 , 5 3 which allows the FPSO to rotate freely about the same axis ZZ, whereas the ring buoy of mooring 1 secured to the external structure 2b has an orientation along said axis ZZ substantially fixed with respect to the seabed.
  • the upper lateral guide bearings 5 3 and lower 5 2 then allow a rotation of the FPSO around the substantially vertical axis ZZ with a minimum of friction and wear when the FPSO is subjected to horizontal forces due to the sea ice, the swell, wind or current.
  • 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.
