Definitions

  • the present invention essentially relates to a single simplified device for mooring and loading or unloading tankers from an underwater fluid supply or evacuation pipe, as well as a method for setting up underwater driving and simplified mooring.
  • a device for mooring on multiple buoys is known, according to which the ship is in an approximately fixed position on six anchors.
  • One of its median manifolds is connected to the underwater supply or evacuation pipe by a flexible tube, resting on the bottom when not in use, and the vessel's sin at the start of each loading or unloading operation.
  • This device however has the major drawback to apply only to sites where, once moored, the ship is permanently in the bed of the prevailing wind, the current and the strongest swell. If the direction of these elements varied, it could be subjected to transverse forces exceeding the capacity of its anchors.
  • the buoy is, on the other hand, connected to the end of the underwater pipe by one or more hoses also underwater as well as to a Pipe End Module, generally provided with remote-controlled valves from the surface.
  • Permanent mooring of the buoy is carried out by means of four to eight anchored chains, each of which must be able to withstand the full pull of the vessel.
  • the device comprises relatively complicated mechanical elements subject to wear and fatigue, such as the single or multi-pass rotary joint and the rotating head for mooring the ship, which constitutes a major drawback.
  • Another mooring device is known on a single mono-anchored buoy which comprises a single vertical and taut chain which ensures the multidirectional anchoring of the buoy to a gravity base, or based on piles.
  • Another major drawback of this known buoy device consists in the fact that a collision of the ship with the buoy, whether due to a wrong maneuver or a reverse current can, not only damage the body of the buoy but also cause the breaking of the anchor chains, the submarine hoses, or even cause the displacement of the Pipe End Module when it is not firmly anchored.
  • this includes a fixed mooring tower which however has the disadvantage of being relatively expensive, this price increasing with the depth of the seabed and these towers must in any case also be provided with appropriate defenses against drifting vessels.
  • the present invention therefore aims to provide a simple solution for the mooring and loading or unloading of tankers in order to lower the cost of supplies, reduce the cost of their installation, eliminate any underwater rotating joint. fast wear, also eliminate the anchor chains, whose durability at sea is unpredictable and always limited; and above all completely eliminate the risk of ships colliding with the mooring-loading point.
  • This solution consists, according to the present invention, in a single simplified device for mooring and loading or unloading of tankers of the type comprising an underwater supply or evacuation fluid line to which is connected at least a flexible tube resistant to torsional forces by means of a Pipe End Module resting on the seabed, comprising an orifice for connection to the flexible tube; the free end of said flexible tube being provided connectable to conduits or manifolds for loading or unloading provided on said ship, characterized in that said end-of-pipe module comprises means for mooring the tanker and is provided for 'a mass sufficient to support the traction of the ship; and the flexible tube is connected at least temporarily to the loading or unloading conduits or manifolds provided on the vessel by means of a Flexible End Module comprising at least one rotary joint rotated during the ship's pivoting or drifting under the effect of external elements such as prevailing winds, currents and swells.
  • the Hose End Module is fixed to the ship, preferably at its bow, the flexible tube comprising at its free end a simple shutter and the Hose End Module comprising a quick coupler associated with its rotating joint.
  • the Hose End Module is reduced to a rotating joint.
  • the Pipe End Module essentially consists of a closed hollow structure comprising internal watertight transverse partitions defining independent ballastable compartments.
  • the pipe end module can have substantially the shape of an "L” or a "T".
  • the Pipe End Module can comprise a rear part fixed to the underwater pipe and comprising a orifice for communication with the underwater pipe and for connection with the flexible tube, and a front part articulated to the rear part to be pivotable relative to said rear part, either in a vertical plane passing through the axis of the underwater pipe, or in a vertical plane perpendicular to the axis of the underwater pipe, ie both.
  • the present invention also relates to a method of fitting the underwater pipe and the aforementioned simplified mooring device according to the invention, characterized in that the non-driving end module is mounted on the ground. ballasted on the underwater pipe, the non-ballasted Pipe End Module thus having its raised front part underwater, the whole underwater pipe-Driving End Module module is hauled by the rear part of the Driving End Module comprising an at least temporary hauling means, and arriving on site, the Driving End Module is ballasted quickly or instantly to cause dynamic self-anchoring of the Driving End Module.
  • the Pipe End Module is also equipped on the ground with its flexible tube and the aforementioned Flexible End Module.
  • a first embodiment of a device according to the single simplified invention for mooring and loading or unloading of a tanker is of the type comprising an underwater pipe 1 of supply or discharge of fluid to which is connected at least one flexible tube 2 resistant to torsional forces by means of a Pipe End Module 4 resting on the seabed 5, comprising an orifice 6 for connection to the Flexible Tube 2; the free end 8 of the flexible tube 2 being provided connectable to conduits or manifolds 10, 12 for loading or unloading provided on the tanker 14.

  • the flexible tube 2 is connected at least temporarily to the loading or unloading ducts or manifolds 10, 12 provided on the ship 14 by means of a Flexible End Module 18 comprising at least one rotary joint 20 rotated during the ship's pivoting or drifts 14 under the effect of external elements, such as prevailing wind, current and swell, thanks to the quasi-torsional deformation of the flexible tube 2.
  • the flexible tube 2 is partially submarine and comprises in its submerged part floats 22 provided to give it an apparent weight almost zero in water, while for its emerged part the flexible tube 2 comprises floats 24 certainly positive buoyancy.
  • This flexible tube 2 must naturally be of length and have sufficient bending properties to allow deformation in harmonious curves and of radius compatible with the torsional stiffness of the flexible or flexible tube 2 which is therefore generally made of reinforced rubber. This deformation without wrinkling or crushing is further facilitated by the close state of weightlessness in which the submerged part of the hose 2 is located.
  • the Flexible End Module 18 is shown moored laterally to the ship 14 using hawsers 26, 28 and therefore the End Module of Flexible 18 includes means 30, 32 for mooring hawsers 26, 28, such as rings.
  • the Flexible End Module 18 has the rotary joint 20 which is incorporated in its mass.
  • the free end 8 of the flexible tube 2 is connected to a part of the rotary joint 20 while the Flexible End Module 18 is connected to the other part of the rotary joint 20 or forms an integral part of this other part, that is to say, in fact the flexible tube 2 is rotatably mounted relative to the Hose End Module 18.
  • the Hose End Module 18 is essentially constituted by a hollow structure which can be metallic and closed at its free end 18a opposite the side where the rotary joint 20 is located.
  • the Hose End Module 18 can include compartments forming integrated floats to ensure positive buoyancy.
  • the Hose End Module can serve as a manifold and be equipped with one or more stop valves 34, 36 from which a flexible tributary flexible tube 38 , 40 which generally has a smaller diameter than the main flexible tube 2 and individually leading to the conduits 10, 12 of the ship 14.
  • the Flexible End Module 18 includes flexible defenses 42, 44 avoiding deterioration during contact with the ship 14.
  • the Flexible End Module can be reduced to a rotating joint 20 which it is then possible to lift out of the water to connect it directly to one of the pipes 10, 12 of the ship 14.
  • connection orifice 6 of the End Pipe Module 4 with the flexible tube 2 is not necessarily located in the extension of the subsea pipe 1 and can be located at the rear of the Module Pipe End 4 being located in a vertical plane, as shown in 50, and then the flexible tube 2 has the position indicated in phantom lines 2 '.

  • a hawser 52 has one of its ends permanently fixed to the mooring means 16 and is provided so as to have its free end of positive flotation which can end with a marking float facilitating fishing of the hawser 52 as for the Hose End Module 18.
  • Pipe End Module 4 can also serve as a manifold and include one or more valves such as 54.
  • the Flexible End Module 18 can be in an advantageous embodiment fixed on the vessel 14 and preferably at its bow, as shown in Figures 3 and 4.
  • the flexible tube 2 comprises at its free end a simple shutter and the Flexible End Module 18 includes a quick coupler associated with its rotary joint 20.
  • the hawser 52 and the flexible tube 2 both terminate at the bow of the ship 14 at neighboring points but with the Flexible End Module 18 slightly away from the 'axis XX of the ship 14 which is necessarily reserved for the fixing of the hawser 52.
  • This arrangement is particularly advantageous in the case of rough seas, on an underwater oil field served by ships which would be specially affected.
  • the flexible tube is advantageously shorter than in the more frequent case of a connection to the standard median manifold of the ship, as shown in FIGS. 1 and 2.
  • hawsers 52 which are generally made of nylon or polypropylene, are subject to fatigue caused by variations in tension and end up breaking if they are not replaced in time.
  • a hawser 52 which leads directly to the End of Driving Module 4 requires to be connected to the mooring means 16 or to be disconnected from it, by plunger.
  • This drawback can be eliminated by modifying the Pipe End Module as shown in FIGS. 5 to 7, so that it includes a rod 60 articulated at 62 at its base on the body 63 of the Pipe End Module 4 resting on the seabed.
  • This rod 60 is advantageously provided with a float 65 so as to have its free end, when a ship is not moored to the End of Driving Module 4 flush with or exceeding the surface of the water so as to be easily locatable and accessible, said free end comprising the aforementioned mooring means 16 of the hawser 52 which is advantageously provided floating and with a locating buoy to facilitate fishing.

  • FIG. 8 to 11 there is shown one of the currently preferred embodiments of the Driving End Module according to the invention which here has substantially the shape of a "T” with preferably the leg of the " T "located in the extension of the underwater pipe 1.
  • the Pipe End module is essentially constituted by a closed hollow structure comprising transverse partitions such as 70, 71, 72 internal watertight defining independent compartments such as 73, 74, 75 , 76 ballastable.
  • the Pipe End Module 4 comprises a rear part 80 fixed to the underwater pipe 1 and comprising an orifice 82 for communication with the underwater pipe 1 and for connection with the flexible tube 2 and a second front part 84 articulated by an articulation 86 to the rear part 80 to be pivotable relative to the rear part 80 either in a vertical plane passing through the axis of the underwater pipe 1, or in a vertical plane perpendicular to the axis of the underwater pipe 1, or both.

  • the flexible pipes and the hawsers tend to s '' wrap around the buoy due to changes in the direction of the current or wind, which causes them damage by friction and requires the presence of a service speedboat at the terminal, in order to untangle these lines before use. This often requires in known devices to anchor them in a fixed direction by means of dead bodies that the service speedboat must go up to the surface when a ship arrives and then the speedboat directs the hawser and the floating pipe in the direction of the ship .
  • the device according to the present invention avoids the presence of a service speedboat because it is easy to fish from the ship to the grapevine marker floats which line the toulines leading to the hawser and the floating hose as is well conceived from figure 18.
  • the device according to the invention has the considerable advantage of not using an underwater rotating joint which is inaccessible from the surface for monitoring and maintenance and / or directly or indirectly subjected to mooring pulls.
  • the flexible pipe goes directly and quite naturally from the underwater pipe 1 to the ship without having to pass through a buoy.
  • the single simplified device for mooring and loading or unloading of fluid according to the invention makes it possible to significantly reduce the installation cost and its cost increases significantly less with the depth of the water than in the case of anterior buoy devices.
  • the invention naturally includes all the means constituting technical equivalents of the means described as well as their combinations.
  • the various embodiments described and shown, and in particular for the Pipe End Module and the Hose End Module can be combined with one another.
  • the Driving End Module 4 can have other shapes and in particular an "I" shape.
