On the lower bell mouth and the compliant riser gap is provided between the bend limiter of least significant end.
The compliant riser is located at top more than sea and is connected on control capstan winch and around pulley, the control
Capstan winch and pulley are fixed in production vessel.
The bend limiter is made of the first semicolumn and the second semicolumn, is led between the first semicolumn and the second semicolumn
It crosses screw rod connection to fix, is formed with standpipe channel on the contact interface between the first semicolumn and the second semicolumn, described is soft
Property standpipe by standpipe channel pass through the bend limiter.
The standpipe channel is positioned away from the position in the center of circle of bend limiter.
Pin groove is additionally provided on first semicolumn, is connected between adjacent bend limiter by pin, pin
One end be inserted into top the pin groove of bend limiter in, the other end of pin is inserted into the pin groove of the bend limiter of lower section.
The standpipe channel is taper, and the diameter of the upper top surface of standpipe channel is more than the diameter of the bottom surface of standpipe channel.
Technical scheme of the present invention has the following advantages that：
Compliant riser armor products in seabed of the present invention are rational in infrastructure, and the rigidity of gradual change is provided using bend limiter, is carried
The moment of flexure transition rigidly fixed between end of compliant riser and compliant riser has been supplied, compliant riser is prevented to occur in use
Bigger flexural deformation avoids compliant riser and generates overbending.
Description of the drawings
Fig. 1 is the overall structure diagram of compliant riser armor products in seabed of the present invention.
Fig. 2 is the cross-sectional view of the bend limiter.
In figure, including：Compliant riser 1, multiple bend limiter 2, guiding tube 3, upper bell mouth 4, lower bell mouth 5, bump joint
6th, sub-sea drilled wells 7, sea bed 8, gap 9, production vessel 10, pulley 11, control capstan winch 12, the first semicolumn 200, the second semicolumn
205th, standpipe channel 210, screw rod 217, pin groove 220 and upper top surface 230.
Specific embodiment
The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention..
As shown in Figure 1, compliant riser armor products in seabed of the present invention include compliant riser 1, multiple bend limiter 2,
Guiding tube 3, upper bell mouth 4, lower bell mouth 5 and bump joint 6, the compliant riser 1 sequentially pass through guiding tube 3, upper bell
Mouth 4, multiple bend limiter 2 and lower bell mouth 5, the guiding tube 3 are fixedly connected on the bottom of production vessel 10, the upper bell
Mouth 4 is fixedly connected on the end of guiding tube 3, and multiple bend limiter 2 are sequentially sleeved at along the length direction of compliant riser 1
On the periphery wall of compliant riser 1, the lower bell mouth 5 is fixedly connected on bump joint 6, and the compliant riser 1 passes through
Lower bell mouth 5 is simultaneously connect with bump joint 6, and bump joint 6 is fixedly attached on sub-sea drilled wells 7, makes compliant riser 1 and seabed oil
Well 7 connects.
Sub-sea drilled wells 7 are arranged on sea bed 8.
On the lower bell mouth 5 and the compliant riser 1 gap 9 is provided between the bend limiter of least significant end.Gap 9
Effect be that the underwater maintenance jacilities such as remote-controlled vehicle is enable to be in direct contact underwater compliant riser, without will be entire soft
Property standpipe, which is moved to, more than the water surface to be repaired.
The compliant riser is located at top more than sea and is connected on control capstan winch 12 and around pulley 11, described
Control capstan winch 12 and pulley 11 are fixed in production vessel 10.The control capstan winch 12 and pulley 11 are described for controlling
Compliant riser 1 gos deep into connecting below sea and finally with sub-sea drilled wells 7.
As shown in Fig. 2, the bend limiter 2 is made of the first semicolumn 200 and the second semicolumn 205, the first semicolumn
200 and second are connected between semicolumn 205 by screw rod 217 and fix, between the first semicolumn 200 and the second semicolumn 205
Standpipe channel 210 is formed on contact interface, the compliant riser passes through the bend limiter 2 by standpipe channel 210.
The standpipe channel 210 is positioned away from the position in the center of circle of bend limiter 2.
Pin groove 220 is additionally provided on first semicolumn 200, is connected between adjacent bend limiter 2 by pin
It connects, one end of pin is inserted into the pin groove 220 of the bend limiter of top, and the other end of pin is inserted into the pin of the bend limiter of lower section
It follows closely in groove 220.
On the one hand the effect of pin makes adjacent bend limiter 2 not lead to standpipe channel 210 due to the rotation of itself not
On the same line, on the other hand the bending angle allowed between adjacent bend limiter can be adjusted by adjusting the length of pin
Degree, the length of pin is longer, and the bending angle of permission is bigger, and the length of pin is shorter, and the bending angle of permission is smaller.
The standpipe channel 210 is taper, and the diameter of the upper top surface 230 of standpipe channel 210 is more than standpipe channel 210
The diameter of bottom surface.
Although above having used general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention belong to the scope of protection of present invention.
