Fig. 5 is the hanging chair type lifting pipe supporting according to one or more embodiment of the present disclosure.
Fig. 6 is the hanging chair type lifting pipe supporting according to one or more embodiment of the present disclosure.
The specific embodiment
When flexible hanging chair type lifting pipe supporting is connected to floating loading and unloading ship time (" carrier "); The flexible hoisting pipe receives axial high pressure; And because of the higher curvature near the stretched wire of access area makes it exceed minimum bending radius, this access area is meant the zone of said pipe near sea bed.Because the dynamic bending waveform that the ocean current of depths and hydrodynamics form possibly make and exceed being worse off of minimum bending radius.
In order to alleviate compression load and to avoid exceeding minimum bending radius, ballast distribution perhaps is applied on the part riser near sea bed in (in the knee of dangling of said pipe) on the access area near riser.The ballast weight application, and prevent the formation of dynamic bending waveform or the dynamic bending waveform is minimized the influence of flexible hanging chair type lifting pipe supporting.
Therefore,, strategically ballast is arranged in the knee of dangling of flexible hanging chair type lifting pipe supporting, is making said pipe under extreme dynamic change situation, form wavy curve according to one or more embodiment of the present disclosure.Likewise, the dynamic bending waveform that forms in the flexible hanging chair type lifting pipe supporting can be controlled because of the layout of ballast and/or minimize.
. the flexible hanging chair type lifting pipe supporting of about-face is machine-processed to the hydrokinetic dynamic response in depths greatly in the distribution of ballast.The distribution of ballast can make ad-hoc location form predetermined wavelength crooked waveform.Therefore, for flexible hanging chair type lifting pipe supporting, can control the dynamic bending waveform and remain under the exercisable state.When flexible pipe receives axial compression because of the fluctuation that loads and the navigation of carrier, the axial compression that the waveform that causes because of the distribution of ballast can make flexible pipe receive minimizes.When receiving axial compression, the amplitude of fluctuation can strengthen.In other words, the direction varicose that flexible pipe can occur towards fluctuation earlier, and do not appear at the axial compression that produces compressive stress in the tube wall.
The amplitude of crooked waveform is controlled by the relative magnitude of the ballast that the bending of dangling along flexible hanging chair type lifting pipe supporting distributes.Further, crooked waveform is controlled by the distributing position of the ballast that is positioned at riser.Therefore, can control weight, the length of each ballast fragment and be distributed with the pipe range of ballast.Ballast can be carried on the half-wave section, and thus, the ballast of certain-length (half-wavelength) is fixed on the flexible pipe, and the back does not have ballast (being naked pipe) with the flexible pipe of certain-length (half-wavelength) on it.Along the knee of dangling of riser, the ballast of available identical or different weight of the configuration of half-wave and/or identical or different length is replacing and repeats to realize shape in wave shape.Preferably, the length of waveform is unified, and each half-wave segment length is unified.Therefore, weight can be distributed on the half-wave section that preestablishes wavelength.
It is the composite soft tube described in 6,491,779. the United States Patent (USP) that the lightweight flexible of here using can be the patent No..Flexible pipe can be nonmetal fully or be essentially nonmetallic.In addition, flexible pipe can be the circulus or the configuration of standard.Flexible pipe can bundle or separate, and is described like standard ISO 13628-2/API17J or ISO 13628-10/API 17K.Perhaps, flexible pipe can be the clad pipe described among the DNV-RP-F202 or name is called the compound riser of describing in the air transport composite material white paper of " thermoplastic composite riser ".Flexible pipe can comprise the interior pressure shell of carrying current, and it is surrounded by composite consolidation layer and shell.Said pipe can be in top ends (perhaps installing on the carrier) accessory place exhaust, and this is because gas possibly gather at the annular region place of interior pressure shell and shell.
According to one or more embodiment of the present invention, dynamically riser analysis (or modeling) can be used for judging the Optimal Distribution position of ballast.Dynamically the riser analysis can judge in advance that the weight of the interval of ballast fragment and length, ballast, length, number of fragments and/or the ballast of waveform install other parameters of distribution before on pipeline.Therefore, according to embodiment of the present disclosure, best configuration can be set before any application-specific of ballast.
Dynamically the riser analysis can be explained the extreme case that is positioned at specific or precalculated position, as, can set century-old environment, be used to explain century-old waveform and 10 years current.Dynamically the riser analysis also can be explained the skew of near-end or far-end.Said skew is meant the lateral separation with respect to the mean place skew of junction, riser top on the carrier.Therefore, riser design and ballast distribution can be in the specified limit environment optimization, thus, can in installation and/or operating process, estimate the load capacity that loads on riser.
Referring now to Fig. 1,, shows the lateral view of hanging chair type lifting pipe supporting.In Fig. 1, show carrier 100 (can be ship, platform or other any riser braced structuress) with two hanging chair type lifting pipe supportings.First riser 101 can be the tubulose or the umbilical of conventional steel, and it is can not be floating, therefore, and when it dangles at carrier 100 last times formation stretched wire shape.Second riser 102 can be lightweight flexible, as stated, is what can float when dangling as hanging chair type lifting pipe supporting in seawater.
As shown in Figure 1, the stretched wire shape of second riser 102 can not normally form because of the buoyancy of flexible pipe.Weight is loaded into flexible pipe with formation tension force in pipe, thereby stability is provided under current intelligence, like U.S. Patent number 7,073, described in 978.According to one or more embodiment of the present disclosure, weight is loaded on the predetermined waveform along the flexible pipe near sea bed.As stated, in the position of said pipe formation stretched wire shape, the knee of promptly dangling, weight can increase tension force and stability is provided this pipe.
According to Fig. 2, show the lightweight flexible that is furnished with ballast now according to embodiment of the present disclosure.On lightweight flexible 202 can be dangled sea bed from carrier 200.Ballast fragment 220,221,222,223 and 224 can be distributed on the pipe 202, shape in wave shape, and wherein, each ballast fragment is corresponding to half-wavelength.Each ballast fragment 220,221,222,223 and 224 weight and/or length are different, preestablish like the additive method of being known by dynamic riser analytical method and/or this area.
As shown in Figure 2, the naked pipe section that ballast fragment 220,221,222,223 and 224 is positioned at the knee of dangling separates, and forms the waveform of ballast distribution thus.Further, as shown in the figure, naked pipe part can have certain curvature because of the buoyancy of said pipe, and on have the pipe of ballast can allow certain controlled curvature in the knee of dangling.
As shown in Figure 2, ballast fragment 220,221,222,223 and 224 is distributed on five half-wave sections.But those skilled in the art will understand ballast half-wave section and have variation more or less.Further, the ballast fragment can inconsistently distribute, and its length can be unified.Further, the weight of ballast fragment can be unified or disunity.As stated, the length of ballast fragment, weight and/or quantity can be determined by dynamic riser analysis.
Fig. 2 shows the flotation tubes lifting process between ballast half-wave section.But it is shown in Figure 2 wavy in order to stop flotation tubes to form that the distributed and arranged in advance of ballast becomes.For example, with reference to Fig. 3, pipe 302 can dangle from carrier 30 as one kind 0, and arranges that above that enough ballasts are to form smooth stretched wire shape.Ballast fragment 320,321,322,323 and 324 distribution can make stretched wire smooth.As stated, the weight of each ballast fragment can be inconsistent, can form conceivable stretched wire shape like this.
