The offshore booster station generally adopts modular installation, integral installation and floating installation due to large total weight. The modular installation mainly comprises the steps that the booster station is divided into a plurality of different modules, such as a transformer module, a high-voltage module, a low-voltage module, a control protection room module and the like, and after installation and debugging of the modules are independently completed on the land, the modules are respectively transported to the site to be hoisted, installed and connected.

The integral installation mainly comprises the steps of welding, manufacturing and assembling the upper blocks of the booster station on land as a whole, installing and debugging equipment, transporting the integral booster station to the site, and installing the booster station by means of a large-scale offshore crane ship. The integral installation mode puts higher requirements on offshore hoisting construction. At present, the number of offshore construction vessels capable of hoisting 2000 tons of modules is large in China, and the rent is relatively low. However, the number of large offshore construction vessels capable of hoisting modules of 4000 tons or more is very small, and the rent is also increased by several times. In addition, the large construction ship is difficult to obtain, and the installation period of offshore construction is seriously prolonged.

The float-over installation is mainly to install the upper block of the booster station by a large barge. However, the floating installation method is more difficult and costly to install.

Based on the above, for solving the whole construction difficulty of large capacity marine booster station to and the great problem that jacket main column increases of traditional modularization installation work volume, reduce installation construction cost, this patent provides a marine booster station of modularization large capacity.

The offshore booster station of the present embodiment. Referring to fig. 1, the offshore booster station includes a support block 11, a transfer block 12, and a platform block 13. The support block 11 is located at the bottom for securing with the seabed. The adapting block 12 is arranged above the supporting block 11. The stage block 13 is used for carrying a booster station, and the stage block 13 is arranged above the transfer block 12. The supporting block 11 is in supporting connection with the platform block 13 through the switching block 12. The booster station has a large capacity, and the weight of the booster station can reach more than 4000 tons.

The bottom of the support block 11 is fixedly arranged on the seabed. The support block 11 may be a truss structure formed by welding round steel pipes. Specifically, the support block 11 includes a plurality of longitudinally disposed vertical columns 111, transversely disposed horizontal conduits 113, and obliquely disposed oblique conduits 115. A rectangular frame is formed between the horizontal guide pipe 113 and the upright 111, and the inclined guide pipe 115 is obliquely arranged in the rectangular frame to enhance the supporting strength of the supporting block 11.

The horizontal duct 113 is provided with two layers. The horizontal pipes 113 of each layer are spliced with each other and distributed in a rectangular square frame.

The bottom of the column 111 is fixed to the sea floor. The upright column 111 is fixedly connected with the seabed through a steel pipe pile on the seabed, and the upright column 111 and the seabed steel pipe pile are usually fixed through an underwater grouting technology. The steel pipe pile and the jacket are connected through grouting, and the grouting connection between the upright column 111 and the steel pipe pile is a weak point of the structure because the underwater grouting quality is difficult to detect and monitor.

As the capacity of the offshore booster cells increases, the number of columns 111 of the conventional offshore booster station increases correspondingly for booster stations with weights of more than 4000 tons, and the number of the conventional columns 111 can be increased to 8, 12 and the like. The number of the upright columns 111 is increased, the number of the steel pipe piles is increased, weak points are increased, and accordingly offshore construction difficulty and cost are increased.

Specifically, in the present embodiment, six columns 111 are provided. Six uprights 111 are distributed along a rectangular box formed by horizontal ducts 113. Wherein, four upright posts 111 are respectively positioned at four top corners of the rectangular square frame. Two upright posts 111 are respectively arranged in the middle of the two long sides of the square frame. Namely, three upright posts 111 are respectively distributed on two sides of the rectangular frame in the long side direction. The support block 11 formed by the six columns 111 has a stable structure, can realize stable support, and can bear a heavy load.

In the present embodiment, the support block 11 can support a large-capacity booster station of 4000 tons or more. The use of as few upright posts 111 as possible can reduce the difficulty of operation of fixed installation of a plurality of upright posts 111 and seabed piles on the one hand, and can reduce the material cost for manufacturing the upright posts 111 on the other hand. The number of the columns 111 is not limited herein, and it is sufficient that a small number of columns 111 are used and stable support can be achieved.

The switching block 12 is provided on top of the support block 11. The switchover block 12 realizes switchover to the platform block 13 by the support block 11. The bottom of the switching block 12 is in fit connection with the top of the supporting block 11, and the area of the top of the switching block 12 is larger than that of the bottom of the switching block 12. Specifically, in the present embodiment, the transfer block 12 includes a first horizontal support layer 121 and a second horizontal support layer 122, the first horizontal support layer 121 is located at the bottom of the transfer block 12, the second horizontal support layer 122 is located at the top of the transfer block 12, and the second horizontal support layer 122 provides a support surface for supporting the platform block 13. That is, the area of the second horizontal support layer 122 is greater than the area of the first horizontal support layer 121.

The adapter block 12 includes a plurality of adapter columns 123 and a plurality of braces 124. The adapter post 123 is disposed longitudinally between the first horizontal support layer 121 and the second horizontal support layer 122. The adapter post 123 is butted against the upright post 111, and the upright post 111 supports the adapter post 123. Since the upright 111 and the adapting column 123 need to be accurately butted when the adapting block 12 is installed above the supporting block 11, the process needs complicated debugging and is difficult to operate. Specifically, in the present embodiment, the number of the adapter columns 123 is equal to the number of the columns 111. A smaller number of columns 111 are used, so that the number of the adapter columns 123 can be reduced, the butt joint operation between the adapter columns 123 and the columns 111 can be reduced, and the difficulty in mounting the adapter block 12 can be reduced.

The diagonal brace 124 is obliquely supported between the first horizontal support layer 121 and the second horizontal support layer 122. The inclined strut 124 and the adapting column 123 are supported between the first horizontal supporting layer 121 and the second horizontal supporting layer 122. The brace 124 may distribute pressure, enhancing the strength of the adaptor block 12.

The adapter block 12 of the present embodiment uses fewer adapter columns 123, and avoids complicated docking operations between too many adapter columns 123 and the column 111. Moreover, the adapter block 12 uses fewer adapter columns 123, and simultaneously enlarges the supporting surface on the top of the adapter block 12. The supporting surface is large and can carry a heavy stage block 13.

The bottom of the platform block 13 is connected with the top of the adapting block 12 in a matching way, and the area of the top of the platform block 13 is larger than that of the bottom of the platform block 13. The top of the platform block 13 is used to support the booster station. The booster station may include a transformer device and a utility.

The platform block 13 includes a plurality of longitudinally disposed platform columns 130, and the distribution area of the plurality of platform columns 130 is larger than that of the plurality of columns 111. The plurality of platform pillars 130 are distributed in a first rectangle, and the plurality of upright posts 111 are distributed in a second rectangle, so that the area of the first rectangle is larger than that of the second rectangle. Therefore, the area of the stage block 13 is increased.

Because the area of the platform block 13 is larger, the number of the platform columns 130 is larger than that of the upright posts 111, and the plurality of platform columns 130 ensure the stability of the platform block 13. Although the number of the platform columns 130 is large, the corresponding number of the upright columns 111 is not required to be correspondingly arranged to support the platform block 13, and the large number of the platform columns 130 is not required to be butted with the upright columns 111. Therefore, on the basis of increasing the area of the bearing surface of the platform block 13, a large number of upright columns 111 do not need to be correspondingly arranged, the manufacturing cost of the upright columns 111 is saved, and the complex operation of fixedly installing the upright columns 111 and the seabed is reduced.

The platform column 130 may also include a base 1301 and an insert rod 1302. The base 1301 is provided with an insertion hole, and the insertion rod 1302 can be directly inserted into the insertion hole and connected with the base 1301. The base 1301 may be welded directly to the second horizontal support layer 122. The insertion rod 1302 is fixedly arranged at the bottom of the platform block 13, so that when the insertion rod 1302 can be directly inserted into the base 1301, the platform block 13 and the adapter block 12 can be stably connected. Moreover, the insertion rod 1302 is provided with a tip which can be accurately and conveniently aligned with the insertion hole, so that quick installation is realized.

The stage block 13 includes a plurality of stages, which are spliced to each other. Referring to fig. 3, two adjacent platforms are connected by a steel grid to form a channel 15 for communication between the platforms.

By dividing one stage block 13 into a plurality of stages which are joined to each other, the weight of each stage is greatly reduced relative to the weight of the entire stage block 13. Therefore, if a large capacity booster station having a weight of 4000 tons or more is installed on two stages, respectively. The weight of the installed platform is approximately 2000 tons. Then to the hoist and mount work of this platform, can rent comparatively common hoist and mount construction ship, not only conveniently rent to rent also reduces.

Specifically, the platform block 13 includes a first platform 131 and a second platform 132. The first and second stages 131 and 132 are joined to each other to form a stage block 13 having a rectangular shape.

Each platform comprises a plurality of spaced apart decks. The first and second platforms 131 and 131 each include a first deck layer and a second deck layer. The first deck level is located at the bottom of the platform block 13 and the second deck level is located at the top of the platform block 13. The first deck level and the second deck level are all equipped with ladder way 14 and connect upper and lower deck level. And an inclined support is also arranged between the first deck and the second deck layer, so that the support strength of the platform can be enhanced.

The first deck level is used for laying out utilities. The public facilities mainly comprise auxiliary modules such as an oil tank module, a heating and ventilation equipment module, a fire pump room module, a temporary rest cabin module, a living water tank module, a water mist module and an accident oil tank module. The utility may be shared by multiple platforms. The public facilities can be integrated module devices, the occupied volume of each module is small, and the space occupation of the public facilities is reduced.

Referring to fig. 2, in the present embodiment, a water mist module 1313 is disposed on the first deck layer 1311 of the first platform 131. The first deck layer 1321 of the second platform 132 is arranged with an oil tank module 1320, a domestic water module 1323, a storage room and work break room module 1324, and a heating and ventilation equipment module, a fire pump room module and the like. The utilities provided on the first deck 1311 of the first platform 131 and the first deck 1321 of the second platform 132 may be shared by the first platform 131 and the second platform 132. Thus, the first deck level 1311 of the first platform 131 and the first deck level 1321 of the second platform 132 provide redundant arrangements that are duplicated and take up less space for utilities. Therefore, the area of the first deck layer is smaller, and the weight and the occupied space of the booster station are reduced.

The second deck layer is used for arranging the transformer equipment. The area of the second deck layer is larger than that of the first deck layer, so that the arrangement of the transformation equipment can be facilitated. The second deck layer can be its area of high efficient utilization, avoids setting up multilayer deck layer. Moreover, the transformer equipment is arranged on the same deck layer, so that control operation among the equipment is facilitated, and maintenance is facilitated. And, the equipment that steps up sets up in the deck layer of two differences with the public facilities differentiation, can be convenient for work and the differentiation of operation such as other life, be convenient for rationalize the management.

Therefore, the weight of the platform block 13 according to the present embodiment is greatly reduced, the weight of the platform block 13 is prevented from being increased, the weight of the entire offshore booster station is prevented from being increased, and the manufacturing cost of the platform block 13 is reduced.
