Abstract
A system and method for mating risers or umbilicals extending vertically or near vertically from the ocean floor to a floating offshore system such as a TLP or semisubmersible platform. The risers or umbilicals are suspended vertically above the vessel's keel and are supported laterally near the platform's keel by keel guides or riser receptacles positioned along the submerged perimeter of the vessel's hull, or within the hull by production riser slots disposed in the bottom of the hull. The keel guides or production riser slots each receive a keel joint assembly which laterally supports a. riser or umbilical passing therein while providing a bearing surface for free vertical movement of the riser.
Description
Background of invention
(1) technical field
The present invention relates generally to offshore hydrocarbon production, and relates in particular to and fix a keel guide around the underwater hull at tension leg platform or other coastal waters ship with vertical or near the ascending pipe or the umbilical duct that vertically rise from sea bed in lateral support.
(2) background technology
In offshore boring and production industry, signal, controlling liquid or chemical inject the submarine well of umbilical duct from the surface, and hydro-carbon in ascending pipe from being transported in the sea on float production platform or the ship.Ascending pipe is to be used for connecting under water at the shaft collar in seabed and to be positioned at production of hydrocarbons disposal system on the floating platform that remains on above the well head.The lower end of ascending pipe is connected with the seabed by the structure that is embedded in the seabed, and is coated with grout or cement.For a kind of floating structure, for example tension leg platform (TLP) but or semi-submerged platform, with support platform ascending pipe is hung and descends from floating watercraft usually.
As illustrated in fig. 1 and 2, a kind of representative type TLP (10) forms by being equipped with the one or more decks (20) that produce and handle the device of hydro-carbon.Deck (20) is supported by hull (18), and its immerses or partly immerse in the water and provides buoyancy for platform.Hull (18) provides attachment point (19) for the tendon (12) that is anchored on the sea bed (11).Hull (18) can comprise one or more water-immersed floating drums, usually they is placed to triangle, the square or circular of level, or cross structure as illustrated in fig. 1 and 2.One or more vertical columns (22) extend upward from hull (18) and pass the water surface and be installed on deck (20).
Ascending pipe (14) or umbilical duct reach platform (10) from submarine well (40).Ascending pipe (14) traditionally vertical hanging and in the underwater by the structure that is connected in platform (10) (16) lateral support.Traditionally, ascending pipe and hull are spaced apart, so that be reduced to minimum because of the power of ambient environment is that cause with collision hull and make ascending pipe be easier to stop.For example, Fig. 1-2 discloses a kind of ascending pipe (14) vertical hanging and under water by the TLP of a kind of prior art mooring of the boom foot that stretches out laterally from hull.
In addition, Fig. 3 and 4 shows a kind of by the prior art TLP (10) in attachment point (19) and hull (18) bonded assembly tendon (12) mooring.TLP (10) has the many pillars (22) that support the superstructure that comprises deck (20).As shown in Figure 4, this TPL hull (18) is made of the foursquare a plurality of floating drums that are formed in the criss-cross.The center of a plurality of ascending pipes (14) of rectangular arranged by platform (10), be suspended on the underwater and leave hull to being supported on inside by netted pole (a 16) network side.US Patent 6273018 has provided a kind of coastal waters floating platform of arrangement of the ascending pipe that adopts similarly, passes the platform center and supported by tendon.
For the coastal waters floating structure, the interfacial design between ascending pipe and the offshore structure must and relatively move and pressure and fatigue that the ascending pipe that causes and dividing range will bear are taken into account load.The coastal waters floating watercraft has the structure of extending and can bear the power of the surrounding environment that causes platform motion below the water surface.The top and bottom of all ascending pipes all are subjected to the influence of platform motion.The power that acts on floating watercraft and ascending tube system comprises owing to heave, pitching, rolling, rock or proportion, the departure distance that is installed in floating installation, the distribution of levels current, platform and well on the ascending pipe, the tension force on ascending pipe top, the rigidity of ascending pipe and the caused power of vertical shift of ascending pipe of surging, wave and the height of surging and cycle, current, the liquid that transmits in ascending pipe.
Environmental activity power can produce the side travel of platform with respect to well head, and this displacement meeting causes the difference of platform skew-between the vertical elevation position of the non-loaded vertical elevation position above the well when being shifted under the environmental forces effect.In other words, because the restriction of tendon, side travel has increased the flat-bed draft.The platform skew causes the variation of ascending pipe pulling force and the variation of ascending pipe effective length (unless ascending pipe and anchor bar coaxial arrangement).Like this, in the platform migration process, between the upper end of ascending pipe and platform, vertical motion slide is arranged.This relative perpendicular movement is exactly the stroke of ascending pipe.
Because normally parallel relation between ascending pipe or umbilical duct and the moored tendons, the stroke of ascending pipe also is a function of platform design.Ascending pipe is located the stroke that has reduced potential ascending pipe near hull, ascending pipe then can be increased the stroke of potential ascending pipe away from the hull location.In order to compensate the stroke of ascending pipe, the ascending pipe upper end is connected with platform by ascending pipe clamping system tension force, relative complex that platform is moved in the ascending pipe that keeps again simultaneously requiring with respect to ascending pipe.
Ascending pipe is placed near hull helps not needing roomy pole network for ascending pipe or umbilical duct provide the lateral support that has increased and simplify.In addition, ascending pipe is placed on can be given platform horizontal-shift near hull and bring the ascending pipe load that reduces to reduce and the stroke of the ascending pipe that reduces reduces, it loosens the designing requirement of ascending pipe tensioner and follows expense to save.The size of tensioner and the reduction of capacity requirement can also reduce deck load and deck construction supports requirement.
