Jet pipe swivel 135 provides rotatable connection and the fluid between jet pipe adaptor union 140 and the jet pipe 110 between anchor 100 and the injection lifter 225 to be communicated with.In order to provide anchor 100 with respect to the rotation of spraying lifter 225, jet pipe swivel 135 comprises one or more sleeve pipes 145 of rotatably connecting around jet pipe 110, is used to receive jet pipe adaptor union 140 and connects the tubulose receiver 150 of two parts 140,145 and is connected in two atubular extension parts 152 between two parts 140,145.In this exemplary embodiment, two are sprayed swivel sleeve pipe 145 and rotatably be connected to jet pipe 110 near the upper ends 125 of plate 105 (Fig. 1).And jet pipe swivel 135 and jet pipe adaptor union 140 connect by inside face and the matching thread on the outside face 154 that is respectively formed at receiver 150 and jet pipe adaptor union 140.Yet in other embodiments, jet pipe swivel 135 and jet pipe adaptor union 140 can connect such as but not limited to J groove connecting device by the connecting device of industrial known another equivalent type.
In order to realize that the fluid between jet pipe adaptor union 140 and the jet pipe 110 is communicated with, tubulose receiver 150 comprises two inlets 156, and each atubular extension part 152 comprises the discharge orifice 162 that extends through it.When jet pipe adaptor union 140 inserts and is connected to receiver 150 and makes that the outlet 146 of jet pipe adaptor union 140 is alignd with the inlet 156 of tubulose receiver 150 basically, as shown, between jet pipe adaptor union 140 and jet pipe 110, provide the fluid connection.On the opposite side of port one 44,156, be provided with two containment members 158, with sealed engagement between jet pipe adaptor union 140 and tubulose receiver 150.In some embodiments, containment member 158 is an O type circle.As mentioned above, the fluid of the port one 46 of outflow jet pipe adaptor union 140 is forced through the inlet 156 of the tubulose receiver 150 of jet pipe swivel 135.Fluid 156 flows towards spraying swivel sleeve pipe 145 by discharge orifice 162 from entering the mouth then.When leaving the discharge orifice 162 that sprays in the swivel sleeve pipe 145, fluid is forced through the inlet 170 of jet pipe 110 by the containment member 164 with spraying swivel sleeve pipe 145 and jet pipe 110 sealed engagement on the opposite side that is arranged on each port one 70.In some embodiments, containment member 164 is an O type circle.From entering the mouth 170, fluid passes the discharge orifice 112 of jet pipe 110 to leave anchor 100 via nozzle 130 (Fig. 1).Leave the fluid of nozzle 130 and in installation process, realize spraying into of anchor 100.
Jet pipe adaptor union 140 deployable one-tenth engage with anchor slab 105 and connect, to prevent that anchor 100 is with respect to 225 rotations of injection lifter.Expanded position is the configuration that is presented by jet pipe adaptor union 140 in the process that sprays at anchor 100.In some embodiments, comprise that jet pipe adaptor union 140 deployable one-tenth engage with plate 105, make lower end 148 screw threads of jet pipe adaptor union 140 be screwed in the port one 07 of plate 105 by those embodiments shown in Fig. 2.Jet pipe adaptor union 140 is in its expanded position in Fig. 2.In this position, jet pipe adaptor union 140 prevents that anchor slab 105 is with respect to 225 rotations of injection lifter.Therefore, plate 105 keeps being arranged essentially parallel to injection lifter 225 in the process of spraying into, and prior, is substantially perpendicular to sea bed.This helps the installation of anchor 100, because need less power to implant anchor 100.
Jet pipe adaptor union 140 is gone back regracting to disconnect from anchor slab 105, to allow anchor 100 with respect to 225 rotations of injection lifter.In some embodiments, comprise those embodiments shown in Figure 2, jet pipe adaptor union 140 regractings disconnect with the port one 07 at its lower end 148 slave plates 105.The configuration of this retracted position for after spraying into of anchor 100 finished, presenting by jet pipe adaptor union 140.In this position, anchor 100 can be with respect to spraying lifter 225 rotations, the purpose that is used to describe below.
Refer again to Fig. 1, anchor 100 also comprises many anchor lines 155 and mooring wiring connector 160.Every rope 155 is connected between the zones of different and mooring wiring connector 160 of face 165 of anchor slab 105.Before anchor 100 was installed, the mooring line was connected in by anchor 100 and is fixed between the boats and ships and adaptor union 160 of appropriate location.After anchor 100 has been mounted, from the load of boats and ships subsequently by mooring line, adaptor union 160 with restrict and 155 be delivered to plate 105.The location of rope 155 and length are chosen to make that when the load from boats and ships was delivered to anchor 100 by this way, plate 105 kept being substantially perpendicular to the mooring line.Thereby anchor 100 is oriented provides maximum loading strength with opposing boats and ships load.The location of rope 155 and/or length may be selected to the function as the expectation angle between mooring line when anchor 100 is mounted and the sea bed 230.
Fig. 3-5 illustrates with comprising that the mooring system 205 of anchor 100 is fixed on boats and ships 200 example system and the method for appropriate location.Begin with Fig. 3, boats and ships 200 comprise location drilling well and/or production facilities 210, pump 215 and lifting apparatus 220 thereon.Injection lifter 225 is suspended to the boats and ships 200 on the sea bed 230.Anchor 100 is connected to by jet pipe adaptor union 140 and sprays lifter 225, as described previously.Mooring system 205 also comprises the mooring line 235 between the mooring wiring connector 160 that is connected in lifting apparatus 220 and anchor 100.
Boats and ships 200 are positioned at the position of expectation at first, so that mooring.Anchor 100 descends towards sea bed 230 by spraying lifter 225.The jet pipe adaptor union 140 of anchor 100 extends in spraying swivel 135, to engage and prevent that with anchor slab 105 anchor 100 is with respect to 225 rotations of injection lifter, as mentioned above.And the extension of jet pipe adaptor union 140 makes the port one 46 of jet pipe adaptor union 140 aim at the port one 56 that sprays swivel 135 basically, thereby the fluid path that sprays between lifter 225 and the anchor 100 is provided, also as mentioned above.When anchor 100 during near sea bed 230, primer pump 215 is transported to anchor 100 by spraying lifter 225 with seawater.Seawater is ejected in the jet pipe 110 from spraying lifter 225 by jet pipe adaptor union 140 and injection swivel 135, finally leaves anchor 100 by nozzle 130.
Refer now to Fig. 4, when anchor 100 arrives sea bed 230, leave the path of the seawater cutting of nozzle 130, make anchor 100 be injected into sea bed 230 by surrounding soil.Spraying into of anchor 100 by this way makes anchor 100 be implanted to desired depth with the littler power of coming self-injection lifter 225 that needs than other modes, and is implanted to the bigger degree of depth more possible than other modes.After anchor 100 arrived desired depth, pump 215 was stopped, and stopped seawater being injected into anchor 100 by spraying lifter 225.
Next, jet pipe adaptor union 140 is with respect to plate 105 withdrawals, to allow anchor 100 with respect to 225 rotations of injection lifter.Subsequently, compressive load is applied to anchor 100 by spraying lifter 225, with respect to spraying lifter 225 rotation anchors 100, makes anchor 100 no longer be substantially perpendicular to sea bed 230, but with respect to sea bed 230 angled orientations.In its spin orientation, anchor 100 is preferably oriented in and makes plate 105 be substantially perpendicular to when spraying lifter 225 to disconnect and boats and ships 200 desired locations that mooring line 235 will present when being fixed on the appropriate location by mooring line 235 from anchor 100.
Disconnect from jet pipe adaptor union 140 subsequently and spray lifter 225, as shown in Figure 5.Boats and ships 200 are maintained fixed in position by mooring system 205.Load from boats and ships 200 is delivered to anchor 100 by mooring line 235.Because anchor 100 is substantially perpendicular to mooring line 235 orientations, so anchor 100 provides maximum loading strength to resist the boats and ships load and keeps implantation.Regain after a while in hope under the situation of anchor 100, jet pipe adaptor union 140 provides connecting device, so that anchor 100 can be pulled from its implantation position.
Fig. 6 has described and has sprayed another embodiment of implanting anchor.Anchor 300 structurally is similar to anchor 100, and following difference is arranged.Anchor 300 comprises the plate 305 of non-rectangular shape, and plate 305 has the lower end 315 of band angle, and the lower end 315 of band angle makes anchor 300 can more easily implant sea bed 230.And plate 305 comprises 120 a plurality of brace panels or the ribs 370 across plate 305 from sidepiece 120 to sidepiece.The structure integrity of rib 370 reinforcement plates 305, therefore and strengthen the load-carrying capacity of anchor 300.Anchor 300 comprises a plurality of nozzles 330, and nozzle 330 is the basic atubular extension part that is connected to the lower end 315 of plate 305.In optional embodiment, nozzle 330 can be integrally formed with plate 305.At last, anchor 300 does not comprise anchor line 155 and the mooring wiring connector 160 included as anchor 100.Instead, anchor 300 comprises the substantially perpendicularly plate 375 of face 165 extensions of slave plate 305.Plate 375 comprises makes mooring line 230 can be attached to its port 380.Except these difference, anchor 300 is substantially similar to anchor 100 in structure, installation and operation.
Anchor 100,300 all sprays into sea bed 230 with the orientation with respect to sea bed 230 perpendicular, so that make the required strength of anchor 100,300 implantation desired depth is minimized.After spraying into, anchor 100,300 is rotated subsequently with load direction that is substantially perpendicular to expectation or mooring line 230 position plates 105,305, so that make anchor 100,300 that maximum load-carrying capacity is provided.In spraying other embodiments of implanting anchor, need after spraying into, not rotate the load-carrying capacity that anchor maximizes anchor.Alternatively, load-carrying capacity strengthens with the face area perpendicular to load direction that increases anchor by launching pivotable anchor fluke.
Now turn to Fig. 7 and Fig. 8, described the embodiment that anchor is implanted in the injection with the pivotable anchor fluke that is in punctured position and expanded position respectively.Anchor 400 comprises tubular member or main body 405 and is attached to tubular member or a plurality of pivotable anchor fluke 410 of main body 405.Tubular body 405 comprises lower end 415, upper end 420 and the discharge orifice 425 that extends between top and bottom.Each anchor fluke 410 is connected to tubular body 405 by two pins 430, and each pin 430 is inserted through anchor fluke 410 and main body 405 on the opposite side basically of main body 405, and fixes by for example nut (not shown).Pin 430 makes that each anchor fluke 410 can be with respect to main body 405 pivoting action between punctured position and expanded position, and in punctured position, anchor fluke 410 abuts against main body 405 and shrinks, as shown in Figure 7, and in expanded position, anchor fluke 410 is away from about 90 degree of main body 405 pivots, as shown in Figure 8.
For anchor 400 is installed, anchor 400 is connected to injection lifter 225 and mooring line 235 (referring to Figure 11), wherein each anchor fluke 410 is in its punctured position.Afterwards, reduce anchor 400 by spraying lifter 225 towards sea bed 230.When anchor 400 during near sea bed 230, primer pump 215 is to be transported to anchor 400 by spraying lifter 225 with seawater.Seawater is from spraying the discharge orifice 425 that lifter 225 flows through main body 405, and leaves main body 405 in its lower end 415.In this way, the effect of nozzle is played in lower end 415, and is different with the nozzle 130,330 of anchor 100,300.When anchor 400 arrives sea bed 230, leave the path of the seawater cutting of main body 405 by surrounding soil, make anchor 400 be injected into sea bed 230.Spraying into of anchor 400 in this way makes anchor 400 be implanted to desired depth with the littler power of coming self-injection lifter 225 that needs than other modes, and is implanted to the bigger degree of depth more possible than other modes.And, because anchor fluke 410 is in the punctured position that abuts against main body 405, so anchor fluke 410 provides the minimum drag to the implantation of main body 405.This also reduces implants the required strength of desired depth with anchor 400.
After anchor 400 is implanted to desired depth, stop to spray seawater by anchor 400.By spraying lifter 225 tensile load is applied to anchor 400 subsequently, to open or to launch anchor fluke 410.More particularly, tensile load is applied to sprays lifter 225, causes and sprays lifter 225 " lifting " anchor 400 certain distances.The upward movement of anchor 400 then causes each anchor fluke 410 resistance surrounding soil and is switched to expanded position from its punctured position.In case anchor fluke 410 launches, then anchor 400 is fixed.
Subsequently, will spray lifter 225 disconnects from anchor 400.Then, by the mooring line 230 that is connected to anchor 400 boats and ships 200 are fixed on the appropriate location.Load from boats and ships 200 is delivered to anchor 400 by mooring line 230.Because the face area perpendicular to the load direction that is provided by the anchor fluke 410 that launches of anchor 400 increases, so anchor 400 has realized that maximum loading strength is with opposing boats and ships load.
Describing with reference to figure 7 and Fig. 8 and in the embodiment shown in Fig. 7 and Fig. 8, anchor fluke 410 is connected to main body 405, make and advance from arbitrary end 415,420 that each continuous anchor fluke 410 is offset 45 degree circumferentially with respect to fwd anchor fluke 410 along the length of main body 405.In other embodiments, anchor fluke 410 can circumferentially be located with respect to main body 405 with different deviation angles.For example, anchor fluke 410 can be staggered along the length of main body 405, makes each continuous anchor fluke 410 circumferentially be offset 180 degree with respect to fwd anchor fluke 410, as shown in Figure 9.Alternatively, each continuous anchor fluke 410 can circumferentially not be offset from fwd anchor fluke 410.In other words, anchor fluke 410 can be aligned, as shown in figure 10.
In addition, anchor fluke 410 can have the shape of the variation of an embodiment that is different from following injection implantation anchor.In Fig. 7-10, the shape of anchor fluke 410 is essentially rectangle.But, in other embodiments, comprise those embodiments shown in Figure 11, for example, anchor fluke 410 can be triangle.And anchor fluke 410 can be crooked, as shown in Figure 7 and Figure 8, or is smooth, shown in Fig. 9-11.
And, anchor fluke 410 can between punctured position and expanded position, pivot about 90 the degree scopes, shown in Fig. 7-10, small range perhaps pivots.For example, Figure 11 has described the anchor 400 with anchor fluke 410, wherein each anchor fluke 410 shown in expanded position and punctured position (referring to Figure 12) between about 45 degree that pivot.For the pivot that limits anchor fluke 410 is no more than 45 degree, each anchor fluke 410 is included near pin 430 angular member 505 from its extension.With reference to Figure 12, each angular member 505 is configured as and receives tubular body 405.Therefore, when anchor fluke 410 is pivoted to its expanded position when (as shown in figure 11) around pin 430 from its punctured position (as shown in figure 12), the pivoting action of each anchor fluke 410 stops during in abutting connection with tubular body 405 at angular member 505.According to the desired nature of soil in position that uses anchor, these variablees refer to that anchor fluke size, range of pivot and shape and length and width make the ability of JIP anchor to be optimised.
Implant in the installation process of anchor in injection, may wish that the action that reduces anchor utilizes anchor heavily to help implant anchor by repeating to promote and the anchor that lands is implanted to the degree of depth of the expectation of sea bed 230 with anchor with pivotable anchor fluke.Preferably, arrive at anchor before the degree of depth of expectation, the anchor fluke of anchor remains on its punctured position in abutting connection with the tubular body of anchor, and does not launch when anchor is repeated to promote.For the tubular body that makes anchor can be held against anchor shrinks, some embodiment of anchor also comprises a plurality of blocking devices that are connected to anchor fluke.
Turn to Figure 13 A and Figure 13 B at last, described the embodiment that anchor is implanted in the injection with the blocking device that is connected to each anchor fluke.Anchor 600 comprises tubular body 405, and a plurality of pivotable anchor fluke 410 is attached to tubular body 405.Each anchor fluke 410 is connected to tubular body 405 by two threaded screws 630, each screw 630 is inserted through the hole 636 in threaded hole 634 and the main body 405 of anchor fluke 410 on the opposite side basically of main body 405, and for example fixing by threaded nut 632.Screw 630 with the anchor fluke 410 that is attached to it can pivot in the hole 636 of main body 405.Because the thread connection of screw 630 and anchor fluke 410, anchor fluke 410 do not pivot with respect to main body 405, unless screw 630 rotates in the hole 636 of main body 405.
