Description

Technical Field

[0003] As a key equipment of FPSO, risers play an important role in transferring oil from subsea wells to the upper hull. According to different functional types, they are divided into rigid risers and flexible risers. Riser sleeve equipment varies according to the type of riser it is connected to. With the advancement of technology, the latest rigid riser sleeve equipment needs to reduce the height of the connection between the support structure and the sleeve due to the addition of a hydraulic pinning system at the lower end of its outer wall. At the same time, in order to conform to the angle between the riser and the main hull, the riser sleeve equipment needs to be tilted at a certain angle, reducing the effective support area between the riser sleeve equipment and the support structure. Finally, the matching umbilical cable needs to pass through the riser sleeve equipment for installation and maintenance, and its convenience of operation needs to be considered. The above requirements put forward greater requirements and challenges for the device supporting the riser sleeve equipment. Utility Model Content

[0039] Although the present invention can be easily embodied as embodiments of different forms, only some of the specific embodiments are shown in the drawings and described in detail in this specification. It should be understood that this description should be regarded as an exemplary description of the principles of the present invention and is not intended to limit the present invention to that described herein.

[0040] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0041] In the embodiments shown in the drawings, the indications of directions (such as up, down, left, right, front and back) used to explain the structure and movement of various elements of the utility model are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0042] It should be noted that the FPSO includes a hull, a ship-side pipeline arranged on the outside of the hull, and a support device arranged on the outside of the hull for supporting a riser. The riser comes from an oil well of a seabed underwater production system, and is arranged on the outside of the hull through a riser support device. A sleeve is provided on the outer periphery of the riser, and the sleeve is fixedly connected to the riser. The riser is fixed to the outside of the hull by connecting the sleeve to the support device. A processing module is provided on the deck of the hull, and the processing module has a plurality of processing units, and the outlets of the processing units are connected to the ship-side pipeline. The number of ship-side pipelines can be set according to actual needs.

[0043] The utility model provides a supporting device, which is used for supporting and fixing a riser on the outside of a hull. The supporting device has high strength and good stability, and can also simultaneously install and support a rigid riser and a flexible riser.

[0044] Figure 1 A schematic diagram showing the support device and part of the hull is shown in FIG. Figure 1 The support device 2 includes a fixing member and a support member 22. The fixing member is used to be fixedly connected to the outer side wall of the hull 1, and the size of the fixing member along the vertical direction gradually decreases from the inside to the outside. The support member 22 is arranged on the side of the fixing member relative to the hull 1. The support member 22 is box-shaped, and has a plurality of independent accommodating cavities inside. The plurality of accommodating cavities are arranged at intervals along the longitudinal direction, and the accommodating cavities are connected from top to bottom, and are used for the riser 3 to pass through and accommodate parts of the riser 3.

[0045] The fixing member includes an upper fixing plate 211 and a lower fixing plate 212 arranged vertically at intervals. The upper fixing plate 211 extends horizontally, and the outer end of the upper fixing plate 211 is connected and fixed to the support member 22. The lower fixing plate 212 is inclined upward from the inside to the outside, and the outer end of the lower fixing plate 212 is connected and fixed to the support member 22.

[0046] The inside and the outside are based on the position of the supporting device 2 relative to the hull 1, the direction toward the hull 1 is the inside, and the direction away from the hull 1 is the outside.

[0047] Combination Figure 1 and Figure 2 The upper fixing plate 211 extends in the longitudinal direction of the hull 1, that is, the upper fixing plate 211 extends from the front end to the rear end of the hull 1. The lower fixing plate 212 extends in the longitudinal direction of the hull 1, that is, the lower fixing plate 212 extends from the front end to the rear end of the hull 1.

[0048] The integral structure of the upper fixing plate 211 and the integral structure of the lower fixing plate 212 improve the strength of the fixing member. The inclined setting of the lower fixing plate 212 makes the fixing member as a whole have a thick inner and thin outer structure, thereby improving the structural strength and stability of the entire supporting device 2.

[0049] Specifically, a plurality of upper notches 2111 are spaced apart on the outer side of the upper fixing plate 211. The upper fixing plate 211 has arc transitions at both ends of the upper notches 2111.

[0050] See also Figure 3 The upper notch 2111 is formed by the middle connecting surface 2115, the arc transition surface 2116 connected to the opposite ends of the middle connecting surface 2115, and the two end arc surfaces 2117. The middle connecting surface 2115 extends in the longitudinal direction. The arc transition surface 2116 is arc-shaped, and the concave surfaces of the two arc transition surfaces 2116 are arranged facing each other. The concave surfaces of the end arc surfaces 2117 face the middle connecting surface 2115, and the two end arc surfaces 2117 gradually move away from the middle connecting surface 2115 when approaching each other. There is a gap between the two end arc surfaces 2117.

[0051] One of the top plates 221 corresponding to an upper notch 2111 extends beyond the end arc surface 2117 in a direction toward another adjacent top plate 221 .

[0052] Arranging the upper fixing plate 211 to be continuous on the outside and having a notch on the inside can not only reduce the number of toes and reduce the risk of structural fatigue, but also effectively reduce the hull 1 beam load borne by the fixing parts.

[0053] The upper fixing plate 211 is also provided with a plurality of upper weight-reducing holes 2112 to effectively reduce the weight while ensuring the structural strength. The upper weight-reducing holes 2112 and the upper notches 2111 are preferably arranged alternately along the longitudinal direction. In this embodiment, the weight-reducing holes are elliptical, and their major axes extend along the longitudinal direction.

[0054] Combination Figure 1 and Figure 4 A plurality of lower notches 2121 are spaced apart on the outer side of the lower fixing plate 212 , and the plurality of lower notches 2121 are arranged corresponding to the plurality of upper notches 2111 .

[0055] The lower notch 2121 is similar to the upper notch 2111, and is formed by a middle connecting surface 2115, an arc transition surface 2116 connected to opposite ends of the middle connecting surface 2115, and two end arc surfaces 2117. The middle connecting surface 2115 extends in the longitudinal direction. The arc transition surface 2116 is arc-shaped, and the concave surfaces of the two arc transition surfaces 2116 are arranged facing each other. The concave surfaces of the end arc surfaces 2117 face the middle connecting surface 2115, and the two end arc surfaces 2117 gradually move away from the middle connecting surface 2115 when they approach each other.

[0056] One of the bottom plates 222 corresponding to the lower notch 2121 extends beyond the end arc surface 2117 toward the other adjacent bottom plate 222 .

[0057] A plurality of lower weight-reducing holes 2122 are also formed on the lower fixing plate 212. In this embodiment, the lower weight-reducing holes 2122 and the lower notches 2121 are alternately arranged at intervals along the longitudinal direction.

[0058] Setting the lower fixing plate 212 to be continuous on the outside and having a notch on the inside can not only reduce the number of toes and reduce the risk of structural fatigue, but also effectively reduce the hull 1 beam load borne by the fixing parts.

[0059] See also Figure 8 , the upper fixing plate 211 is aligned with the longitudinal member of the hull 1, and the lower fixing plate 212 is aligned with the longitudinal member of the hull 1. Specifically, the upper fixing plate 211 and the lower fixing plate 212 are respectively aligned in height with the two longitudinal members spaced vertically. Aligning the inner sides of the upper fixing plate 211 and the lower fixing plate 212 with the longitudinal members of the hull 1 can effectively resist the load of the riser 3 transmitted to the hull 1 and provide strong support.

[0060] Continue reading Figure 1 The fixing member further includes a plurality of upper brackets 213 spaced apart in the longitudinal direction of the hull 1 and a plurality of lower brackets 214 spaced apart in the longitudinal direction of the hull 1. The upper brackets 213 and the lower brackets 214 are provided to further improve the structural strength of the fixing member and the supporting strength of the supporting member 22.

[0061] The upper toggle plate 213 is vertically arranged. The upper toggle plate 213 is fixed to the top of the upper fixing plate 211 and extends outward to be connected with the support member 22.

[0062] Specifically, the inner side wall of the upper bracket 213 is in contact with the outer side of the hull 1, and the outer side of the upper bracket 213 is arc-shaped, and the concave surface of the arc faces outward, so that the upper bracket 213 tilts outward from top to bottom.

[0063] The upper bracket plate 213 is provided with a plurality of reinforcing ribs, which effectively increase the rigidity and anti-buckling performance of the upper bracket plate 213 and improve the supporting strength of the supporting member 22 .

[0064] A plurality of reinforcing ribs are arranged at intervals. The plurality of reinforcing ribs may include a first reinforcing rib 215. The first reinforcing rib 215 is arranged on the side of the upper bracket 213 and is inclined outward from top to bottom. Specifically, the first reinforcing rib 215 extends from the upper part to the bottom of the upper bracket 213. The plurality of reinforcing ribs may include a plurality of second reinforcing ribs 216 arranged at intervals along the vertical direction, the second reinforcing ribs 216 extend in the transverse direction and are connected to the inner side of the first reinforcing rib 215. The second reinforcing rib 216 extends from the inner side of the first reinforcing rib 215 to the inner end of the upper bracket 213 and is connected to the outer side wall of the hull 1.

[0065] The lower toggle plate 214 is inclined upward from the inside to the outside, and the top of the lower toggle plate 214 is connected to the bottom of the support member 22. In this embodiment, the lower toggle plate 214 and the upper toggle plate 213 are arranged in a one-to-one correspondence.

[0066] Specifically, the lower bracket 214 is roughly triangular in shape. The inner side of the lower bracket 214 fits the outer side of the hull 1, the top of the lower bracket 214 fits the lower fixing plate 212, and the lower bracket 214 extends outward to be connected and fixed to the bottom of the support member 22. The outer side of the lower bracket 214 is inclined outward from bottom to top, and the lower part of the outer side of the lower bracket 214 is smoothly transitioned.

[0067] Furthermore, the toe ends of the upper bracket 213 and the lower bracket 214 close to the inner side of the hull 1 are set as soft toes, which can effectively reduce the fatigue risk of the structure.

[0068] The upper bracket 213 and the lower bracket 214 are arranged corresponding to the transverse member of the hull 1. At the same time, the upper bracket 213 and the lower bracket 214 also correspond to the bulkhead 225 of the support member 22.

[0069] The support member 22 is located outside the fixing member. Figure 1 , Figure 7 and Figure 8 The support member 22 includes a top plate 221 and a bottom plate 222 arranged in parallel and spaced apart, a side plate 223 connecting the top plate 221 and the bottom plate 222 on both sides, and an end plate 224 connecting the top plate 221 and the bottom plate 222 on both ends. The top plate 221, the bottom plate 222, the side plates 223 and the end plates 224 enclose a box-shaped structure with space inside. The support member 22 includes a plurality of partitions 225 arranged at intervals along the longitudinal direction of the hull 1. The plurality of partitions 225 are located in the box-shaped structure and divide the space inside the support member 22 into a plurality of independent accommodating chambers.

[0070] Each accommodating cavity is used to accommodate a riser 3 respectively, so a support member 22 can support multiple risers 3 at the same time, and can be used to support both rigid risers and flexible risers.

[0071] Specifically, the two side plates 223 are arranged at intervals in the transverse direction, each side plate 223 is arranged vertically and extends in the longitudinal direction. The two end plates 224 are arranged at intervals in the longitudinal direction, each end plate 224 is arranged vertically and extends in the transverse direction.

[0072] See also Figure 5 A plurality of operation holes 2231 are provided on the two side plates 223, and the plurality of operation holes 2231 are arranged at intervals in the longitudinal direction. The operation holes 2231 meet the minimum aperture for construction personnel to pass through, maintain a large effective shear area as much as possible, and increase the shear bearing capacity of the support device 2.

[0073] Figure 1The view at EE (not shown) is similar to Figure 5 The same, that is, the structures of the two side plates 223 are the same.

[0074] In this embodiment, two operation holes 2231 are opened on a box body of a side plate 223. In other embodiments, the number of the operation holes 2231 is set according to actual needs.

[0075] The partition 225 is parallel to the end plate 224. The top and bottom of the partition 225 are fixedly connected to the top plate 221 and the bottom plate 222 respectively. Thus, the support member 22 is divided into a plurality of independent accommodating chambers. In this embodiment, part of the partition 225 is arranged corresponding to the transverse members of the hull 1, and part of the partition 225 is located between two adjacent transverse members.

[0076] An end plate 224, a partition plate 225, a top plate 221, a bottom plate 222 and two side plates 223 are enclosed to form a box, and two partition plates 225, a top plate 221, a bottom plate 222 and two side plates 223 are enclosed to form a box, that is, the support member 22 includes a plurality of boxes. Each box has a containing cavity. Specifically, the containing cavity is arranged in the center of the box. Among them, the length of the box is not less than 2.5m, and the width of the box is not less than 2.5m. The length of the box refers to the dimension along the longitudinal direction, and the width of the box refers to the dimension along the transverse direction.

[0077] By limiting the size of the box as mentioned above, sufficient installation space is left in the box, ensuring that the sleeve has strength reserve at all tilting angles, so that the support member 22 has universality.

[0078] The support member 22 also includes a reinforcement component corresponding to each accommodating cavity. Figure 2 , Figure 3 and Figure 6 The reinforcement assembly includes a plurality of reinforcement elbow plates 226, which are evenly arranged along the circumferential direction. The outer end of each reinforcement elbow plate 226 is connected to the side plate 223 or the end plate 224, and the inner end of the reinforcement elbow plate 226 is used to abut against the riser 3. The top and bottom of the reinforcement elbow plate 226 are respectively connected to the top plate 221 and the bottom plate 222.

[0079] In this embodiment, the reinforcement assembly includes four reinforcement brackets 226, two of which extend in the longitudinal direction and two of which extend in the transverse direction.

[0080] There are multiple support members 22, and the multiple support members 22 are arranged at intervals along the longitudinal direction of the hull 1. That is, the support members 22 are independent of each other.

[0081] The top plate 221 of the support member 22 is formed by the upper fixing plate 211 of the fixing member extending outward in an integral manner. The integrally extended structure improves the structural strength of the entire support device 2 and improves stability.

[0082] The longitudinal interval between two adjacent support members 22 is 300-500 mm, which is used for the installation and maintenance of the matching umbilical cable 4.

[0083] The top plates 221 of the plurality of support members 22 are spaced apart in the longitudinal direction, and the bottom plates 222 are spaced apart in the longitudinal direction, so that the load on the beam of the hull 1 borne by the support members 22 can be effectively reduced.

[0084] Based on the above introduction, the supporting device 2 of this embodiment has the following advantages:

[0085] 1. The upper fixing plate 211 is arranged horizontally and the lower fixing plate 212 is arranged obliquely, so that the support member 22 forms a cantilever beam structure with a thick inner part and a thin outer part, thereby improving the stability and strength of the integrated structure.

[0086] 2. The multiple independent accommodating cavities of the support member 22 can ensure that the rigid riser and the flexible riser sleeve equipment can be installed and supported at the same time.

[0087] 3. The size of the box is limited so that there is enough installation space in the box, ensuring that the sleeve has strength reserve at all tilt angles, and making the support member 22 universal.

[0088] 4. The upper fixing plate 211 and the lower fixing plate 212 are both set to be continuous on the outside and have a notch on the inside, which can not only reduce the number of toes and reduce the risk of structural fatigue, but also effectively reduce the hull 1 beam load borne by the fixing parts.

[0089] 5. The support members 22 are arranged at intervals along the longitudinal direction, which is convenient for the installation and maintenance of the matching umbilical cable 4. Moreover, the support members 22 are arranged in a disconnected manner, which can effectively reduce the load on the hull beam 1 borne by the support members 22.
