Embodiment 1

[0048] Embodiment one, such as figure 1 , 2 As shown, a high-load semi-submersible drilling platform sea wave compensation device includes a buoyancy tank 1, a load-bearing pillar 2, a parallel attitude adjustment module 3, a wave recognition module, a data processing module 13, a control and drive module 14, and a drilling platform deck 4.

[0049] The buoyancy tanks 1 are ring-shaped, arranged under the semi-submersible drilling platform and suspended below the sea surface. The function of the buoyancy tanks 1 is to keep the drilling platform floating on the sea surface by buoyancy.

[0050] The load-bearing pillar 2 is cylindrical, and the load-bearing pillar 2 is located above the annular buoyancy tank. The axis of the load-bearing pillar 2 is located on the circumference of a specific circumscribed circle.

[0051] Such as image 3 , 4 As shown in and 5, the parallel attitude adjustment module 3 is located between the supporting pillar 2 and the drilling platform deck...

Embodiment 2

[0068] Embodiment two, such as Figure 11 As another embodiment of the present invention, the number of bearing pillars 2 and parallel attitude adjustment modules 3 is 6, and the sea wave compensation device and its control method for a high-load semi-submersible drilling platform provided by this embodiment are similar to those of Embodiment 1.

Abstract

The invention discloses a high-bearing-capacity semi-submersible type drilling platform sea wave compensation device and a control method. The high-bearing-capacity semi-submersible type drilling platform sea wave compensation device comprises a floating box, a bearing supporting column, a parallel connection posture adjusting module, a sea wave recognition module, a data processing module, a control and driving module and a drilling platform deck, wherein the bearing supporting column is connected to the upper portion of the floating box, and the bearing supporting column is connected with the parallel connection posture adjusting module; the parallel connection posture adjusting module is connected with a drilling platform deck; the number of the bearing supporting columns is equal to that of the parallel connection posture adjusting modules; an acoustic wave tester in the sea wave recognition module is used for measuring sea wave flow parameters, a gyroscope is used for measuring the pose of a buoyancy tank coordinate system relative to a deck coordinate system, a data processing module is used for processing the sea wave motion parameters, and a control and driving module is used for controlling a linear motion unit to move. The device has the advantages of being high in bearing performance and good in stability, and composite motion compensation of the semi-submersible drilling platform on transverse movement, longitudinal movement, heaving, rolling, pitching and yawing of sea waves can be achieved.

Description

technical field [0001] The invention relates to a floating structure, in particular to a high-load semi-submersible drilling platform system and a control method, belonging to the field of marine engineering equipment. Background technique [0002] With the continuous advancement of the national ocean power strategy, all kinds of high-end marine engineering equipment have achieved important development. The exploration and development of offshore oil and gas resources can effectively solve the problem of land oil and gas shortage. The equipment currently used for offshore oil and gas resource exploration mainly includes exploration drilling ships, jack-up drilling platforms and semi-submersible drilling platforms. Among them, drilling exploration ships are usually used for preliminary exploration and scientific investigation of marine resources, and cannot carry out development and production operations of marine oil and gas resources. Jack-up drilling platforms are usuall...
