[0063] Embodiment of the present invention discloses a method of water offshore platforms, such as Figure 1 - Figure 12 As shown, the water offshore platform comprising the steps of:
[0064] Sl, decentralized legs, so that the submersible pump 22 and pipe 21 with the pump tower legs sneak below sea level;
[0065] S2, operation of the lift assembly 3 gradually increase the pump column pipe 21, so that the pump 21 submersible pump connected to the column tube 22 reaches a predetermined height;
[0066] S3, movement of the drive support assembly 4, the support assembly 4 and the column tube 21 abuts against the pump;
[0067] S4, the water pipe system in communication with the pump 21 column;
[0068] S5, start the submersible pump 22.
[0069] Thus, water offshore platform method of this embodiment, it is possible to achieve water offshore platform, a simple operation of the entire process water. The water offshore platform apparatus and a method comprising the following advantages: submersible pump 22 and a pump column pipe with legs 21 can dive into the sea, without additional lowering apparatus, simplifying the structure and operation; increased gradually by operating the third pump assembly lifting column tube 21, that the submersible pump connected to the column tube 21 of the pump 22 reaches a predetermined height, thereby achieving submersible pump 22 and a pump height adjustment column tube 21 to meet the water needs of different locations; a support assembly 4, the support column with the pump assembly 4 pipe 21 abuts, to achieve the stability limit of the pump tube support column 21, to improve the structure.
[0070] Hereinafter, the steps of the method of offshore platform abstraction particularly described.
[0071] Sl, decentralized legs, so that the submersible pump 22 and pipe 21 with the pump tower legs sneak below sea level.
[0072] Leg marine platform support portion, by the submersible pump 22 and a pump 21 is associated with the column tube legs, so that when decentralized legs, and can be realized decentralized pump 21 submersible pump column pipe 22, simplifying the structure and operation Process.
[0073] Specifically, steps S1 comprising:
[0074] S11, sailing the marine platform to the designated sea area;
[0075] S12, decentralization of legs, and a pump 22 submersible pump column pipe 21 with legs sneak below sea level;
[0076] S13, the pile shoe into the mud fixed offshore platform to enhance the main structure, the main structure height from sea level, there is a certain safety stop after the upgrade.
[0077] When sailing offshore platform to the designated area, the decentralization of the leg boots into the mud pile fixed to achieve the initial fixed for offshore platforms. Offshore platform structure to further enhance the body, the body structure has a certain safety height from the sea level to stop the lift, so as to facilitate marine operations. Meanwhile, the submersible pump 22 and a pump column pipe 21 with the legs sneak sea, without additional lowering apparatus, simplify the construction and operation.
[0078] S2, operation of the lift assembly 3 gradually increase the pump column pipe 21, so that a submersible pump connected to the pump 22 to the column tube 21 a predetermined height.
[0079] The pump assembly 3 by lifting the riser column 21 and submersible pump 22, enables the submersible pump 22 reaches a predetermined height of water, to meet the different needs of water. Incidentally, predetermined height of the submersible pump 22 safety distance from the seafloor, seabed mud entering the submersible pump to avoid damage to 22, for example, may be a predetermined height 4m-6m, according to the specific needs to be set according to the present embodiment is not particularly limited .
[0080] like Figure 5 - Figure 9 Shown, alternatively, the step S2 is lifting assembly 3 comprises a shackle 34, hoist 32 and the shackle 34 and the hoisting ropes 32 are connected to the hoist 33, further, comprising the step S2:
[0081] S21, the shackle 34 on the lugs 211 of the pump 21 is connected to the column tube;
[0082] S22, operation hoist 32, the lifting cord 33 and the pump drive column tube 21 connected to the submersible pump 22 reaches a predetermined height.
[0083] like image 3 with Figure 4 Shown, in this embodiment, the lugs 211 along the longitudinal direction of the tube pump tower 21 is provided with a plurality of spaced, shackle 34 which is selectively connected to a lug 211 on. Click, 32 by operating the hoist, the hoisting ropes 33 drives the pump column pipe 21 upward, when the lug 211 to be connected to the shackle 34 and the hoist 32 is high (i.e., the pump tube 21 can not lift the column node), detached shackles 34 so that shackle 34 211 is connected to a lower lug, lift pump 32 continues to operate hoist tower tube 21, in cycles, until the submersible pump 22 is stopped reaches a preset height.
[0084] S3, movement of the drive support assembly 4, the support assembly 4 and the column tube 21 abuts the pump.
