Description
Technical field
The present invention relates to a kind of standpipe that is used between first member in seabed and second member, carrying liquid on the sea, comprise the upper section that an approximate vertical is extended and is connected with the sea member in the top, at least one part along its length connects the mid portion of standpipe of one or more buoyancy aid elements and its lower end and is connected to bottom part on the member of seabed.
Background technology
Carry to the sea from the seabed that liquid is known many dissimilar standpipes.The common type such as " Lazy S " and " Steep S " that is configured with, they all make standpipe stretch to the seabed by a zone line.At mid portion, standpipe is connected on one or more buoyancy elements, and described buoyancy elements is mentioned the appropriate section of standpipe and formed one to recessed curved surface.
From above-mentioned zone line, in " Lazy S " structure, standpipe to the seabed with mild curve extension, and in " Steep S " structure, standpipe extends with a more straight line to an anchor in seabed, it also comprises a coupler that is used on the pipeline, and described pipeline extends between grappling and the seabed member.
Shortcoming about " Lazy S " structure is that it needs more space, makes it have standpipe mutually near also impaired danger.This makes it be difficult to be used in the bigger structure with many standpipes and big degree of depth.
The solution of grappling " Steep S " has been controlled the vertical direction of standpipe and moving of horizontal direction preferably, and still, in being anchored to the mode in seabed, being of coupled connections is more complicated, and needs special equipment in order to finish to connect.Also have, if grappling is destroyed, standpipe will on float on the sea, it will fundamentally become unstable like this.
A solution between these two selection schemes is presented among the US4906137.In this case, anchor is fixed on the bottom part of standpipe, so that obtain one stretchable section between buoyancy elements that is coupled to mid portion and seabed, makes standpipe obtain a quite clear and compact improvement as " Steep S " scheme.Anchor is connected on the standpipe, makes standpipe have a level and smooth curve transition passage with predetermined curvature from vertical to level.Standpipe can further stretch to the seabed member, or is connected with a pipeline in the seabed in a common mode.Because anchor, if seabed member or anchor are out of joint, this technical scheme also is damaged easily.May be destroyed thereby equally be easy to be subjected to the influence of tensile stress and flexural stress at the Coupling point between the anchor on the standpipe, this is because caused big the moving in riser top of ship or platform.
The shortcoming of above-mentioned United States Patent (USP) is that it is very little with respect to the big mobile flexibility on the standpipe.And it need be connected to anchor on the standpipe on the seabed with the operation of a relative complex.
Summary of the invention
The present invention relates to a simple solution and be similar to the standpipe that " Steep S " constructs in order to obtain one, because in the standpipe installation process, the counterweight element that is fixed on the standpipe can be mounted in the assembling ship across the sea, thereby standpipe is connected to the seabed does not need complicated operations.
The counterweight element is connected to also can be simpler than the described prior art of above-mentioned United States Patent (USP) on the anchor of suitably pre-installing, and this is because anchor chain can be mounted by a relaxed state, has so simplified attended operation.
The invention provides a kind of being used for is in or near the standpipe of carrying fluid between second member on sea member in seabed and one, this standpipe comprises a vertically extending upper member, the upper end of described upper member is connected on the member that is positioned at the sea, the mid portion of a standpipe, on at least a portion of its length direction, connecting one or more buoyancy elements, a lower member, have a lower end that is connected on the member of seabed, it is characterized in that also having one or more counterweight elements to be installed on the lower member of standpipe.
Thus, a technical solution that is obtained, its existing retractility as " Lazy S " structure is almost compact as " Steep S " simultaneously again.
Accompanying drawing is described
The present invention will be described in more detail below in conjunction with accompanying drawing, and accompanying drawing has shown the embodiment that the present invention is possible.
Fig. 1 a shows complete riser configuration.
Fig. 1 b shows the structure that another is relevant with the present invention.
Fig. 2 a and 2b show the details of constructing shown in above-mentioned Fig. 1 b.
Fig. 3 shows the details of the standpipe bottom with counterweight element.
Fig. 4 is one and shows two sectional drawings that are installed in the counterweight element on the standpipe.
The specific embodiment
Among Fig. 1 a, show a floating platform 1.A standpipe 2 is connected with described platform by being installed to a coupling unit on the installation deck.Platform self is unimportant for the present invention, and the top of standpipe may be coupled on other member certainly, as boats and ships, and the particularly loading ship of a diving turntable or extracting boat.
Among the figure, the top 2a of standpipe is substantially perpendicularly hanging from above.Mid portion 2b has many buoyancy elements 8 in known manner, and buoyancy elements is arranged on and is used to make standpipe crooked on this part on the mid portion.
Standpipe also comprises one section bottom part 2c below buoyancy elements.Bottom part 2c reaches the seabed at least downwards, and best coastal end stretch is prolonged.Many counterweight elements 3 are set on the bottom, so that the buoyancy that the balance buoyancy elements produces, it plays the restriction standpipe simultaneously and moves both vertically.Preferably make at least one counterweight element be positioned at the seabed, produce the effect that moves horizontally of a restriction and standpipe quadrature like this, thereby the danger of colliding mutually between standpipe has been reduced.Because the rising of standpipe can make the counterweight element be raised from the seabed, so just increase standpipe and floated in the water partly weight, again standpipe is pulled down thus, this also plays the effect of stablizing standpipe upright position in water.
A special embodiment of the present invention is presented among Fig. 1 b, wherein one or more counterweight element 3b that mentioned from the seabed are connected to a buoyancy aid 12 by first anchor chain or like, and buoyancy aid 12 further is connected to an anchor 14 by one second anchor chain or like 13 and is anchored at the seabed.Provided an additional grappling on the top of counterweight element like this, it is resisting the possibility that moves and reduced simultaneously the curvature changing of standpipe bottom part 2c of standpipe horizontal direction.When the top of standpipe when being pulled with the crooked identical direction of bottom part 2c, as because the drift of platform 1, then described radius of curvature generally is reduced.Described grappling generally can suppress the minimizing of above-mentioned radius of curvature, and this is owing to the anchor chain that is laid on the seabed is upwards drawn from the seabed, and this anchor chain is fixed on the counterweight element, helps to increase gradually horizontal direction like this and resists the power that standpipe moves.The radius of curvature that together helps avoid standpipe bottom part with the rigidity of counterweight element is reduced to below the critical limit like this.
Shown in Fig. 1 b, when the sea member be set at the seabed member directly over the time, additional grappling the 11,12,13, the 14th, particularly advantageous, for example one of them well casing 15 reaches well head 7 from platform 1.If not additional grappling, one makes the standpipe bending along shoving of paper inward-outward direction in the inside or outside direction along paper in the drawings.Above-mentioned warpage may destroy standpipe, and this is because the bending of standpipe has surpassed the critical limit of standpipe and has been arranged on the result that the same area internal riser collides mutually.The anchoring system 11,12,13,14 that the above-mentioned bottom part that is arranged on standpipe 2c is protruded a side can reduce to acceptable degree with above-mentioned warpage.
For keeping the balance of buoyancy elements and counterweight element 3,8 structures, the buoyancy of buoyancy aid 12 is suitable for making only horizontal force of effect on counterweight element 3 of first anchor chain 11.Buoyancy aid 12 and corresponding anchor chain 11,13,14 etc. thereof can be arranged on the seabed respectively and be connected on it like this, and can not influence counterbalance effect, improve outer equilibrium state characteristic simultaneously.Buoyancy aid can be anchored at a selected position and first anchor chain can be connected on one of them counterweight element with a ROV (remote control means of transportation) subsequently.If grappling was lost efficacy, standpipe will keep same vertical position also substantially.With corresponding to the identical mode of known above water craft anchoring system, buoyancy aid provides a ratio directly to be anchored on the softer grappling in seabed, like this before standpipe is impaired, allow more drift to assemble across the sea, and when first anchor chain 11 is connected on the counterweight element 3, limit the weight of being mentioned by ROV simultaneously.
Fig. 2 a and 2b have shown the anchoring members shown in above-mentioned Fig. 1 b, and wherein Fig. 2 a has shown the mode of occupation of the buoyancy aid 12 that is connected to standpipe 2, and Fig. 2 b has shown that correspondingly the anchor chain 11,13 that passes through to be connected is connected to the mode of occupation of two buoyancy aids of standpipe 2.Technical scheme shown in Figure 2 has been improved the stability that horizontal direction moves.
Detailed explicit declaration in Fig. 3 have the bottom part of the standpipe of counterweight element 3, one of them counterweight element 3b comprises the fixture that is used to connect anchor 11,12,13,14.Except that the counterweight element 3b that is anchored, accompanying drawing has also shown a counterweight element 3a that size reduces gradually, and it provides the transition between standpipe and the counterweight element.For the counterweight element that is layered at foot on the seabed, the counterweight element can be uniformly set.
Fig. 3 shows how the counterweight element is installed on the standpipe to keep flexible, and this is because the counterweight element along the standpipe setting, has a distance piece 10 between the counterweight element to make and has certain spacing between them.
A counterweight element is preferably only arranged, and simultaneously preferably nethermost one is fixed on the standpipe, and other only interfix, so that allow the counterweight element longitudinally relative to freely moving.When curvature changing, standpipe can not be subjected to the influence of any additional pulling force like this.
Be the big curvature of avoiding occurring on standpipe owing to crooked, counterweight element and midfeather parts have a level and smooth rigidity.This rigidity reduces so that progressively carry out the transition to the rigidity of standpipe towards its end.
For avoiding curvature to surpass a certain boundary, radially extending of counterweight element 3 can be greater than the distance of 3 of counterweight elements.The radius of selected counterweight element and the relation of the spacing between them make the counterweight element be in contact with one another when standpipe is a certain curvature, stop the further bending of standpipe 2 like this.
As a kind of substitute mode, distance piece 10 can place between the counterweight element, and it can regulate bending rigidity, makes the hardness of operation be not less than the critical bends radius of standpipe 2.If the standpipe with counterweight element is made the counterweight element be in contact with one another by crooked fully, distance piece can bear the tension force that produces in the outside of bending.
Except that the above-mentioned advantage that is obtained by employing counterweight element of the present invention, when be subjected to respect to the seabed move influence the time, it also will make standpipe obtain certain protection of wearing and tearing of preventing.
Fig. 4 has shown the sectional view of structure of the counterweight element 3 of an embodiment.Counterweight element 3 can form an annular, as lead ring, is fixed on the standpipe 2 by certain distance each other.The flexibility of standpipe has been held like this.
In an alternative embodiment, the counterweight element can have hyperbaric liquid, as drilling fluid.If the counterweight element is full of with liquid, they also can have suitable flexibility, when standpipe is crooked, owing to the counterweight element is little by little pressed to together mutually, thereby provide a damping to increase in bending rigidity like this.Liquid can pour into after the counterweight element is mounted in the counterweight element, has simplified operation like this.
Preferably counterweight element 3 is to be screwed in together semicircular feature in the standpipe outside with screw.Annular 3 shown in Fig. 4 is assembled by interior ring 4, and interior ring 4 has the flexible polymer body of the material of rubber and so on.In ring 4 bonded or be vulcanized on the outer shroud 5, outer shroud 5 is by heavy weight material, preferably lead is made, or comprises the heavy-fluid body.In the outside, an O type ring 6 has provided the protection of an outside.
The hardness of counterweight element and the connection between them can provide with other mode, as in the manufacturing process of counterweight element and possible distance piece, adopting different rubber compositions, perhaps be combined in and use the heavy-fluid body in the counterweight element, thereby provide their certain elasticity.
