Description

Technical Field

[0001] The utility model relates to the technical field of offshore rocket launching platforms, in particular to an inclined six-column semi-submersible platform. Background Art

[0002] The most serious impact of the current offshore rocket launch platform on the heave motion under the influence of wind, waves, currents and rocket wakes is mainly the heave motion, so reducing the heave motion has become a very important content. Common ways to reduce heave motion include installing heave plates, increasing the waterline area and other methods. Most of the offshore launch platforms are converted from offshore oil production platforms. At present, someone has proposed a method of inclined columns for self-stabilizing semi-submersible platforms. The existing platform has large resistance when moving at sea and is not flexible. Secondly, the existing device does not have better balance at sea, and at the same time, the existing device does not have a greater load-bearing effect.

[0003] There is an urgent need for an inclined six-column semi-submersible platform to solve the above problems. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an inclined six-column semi-submersible platform, which is achieved through the following technical solutions.

[0005] An inclined six-column semi-submersible platform comprises a building platform, wherein the bottom of the building platform is fixedly connected with an inclined column, one end of the inclined column away from the building platform is fixedly connected with a pontoon, the bottom of the pontoon is fixedly connected with a truss, and one end of the truss away from the pontoon is fixedly connected with a heave plate.

[0006] Furthermore, the building platform and the pontoon are parallel to each other.

[0007] Furthermore, there are two pontoons symmetrically arranged, and the two pontoons are located directly below the building platform.

[0008] Furthermore, two groups of the inclined columns are provided, and each group of the inclined columns is provided with three.

[0009] Furthermore, the inclined column is connected between the building platform and the pontoon in an inclined manner, and one end of the inclined column connected to the pontoon is inclined inwardly by 30°.

[0010] Furthermore, two ends of the buoyancy box form a triangular structure.

[0011] Furthermore, the number of the heave plates is symmetrically arranged, the two heave plates are located directly below the pontoon, and the heave plates and the pontoon are parallel to each other.

[0012] The beneficial effect of the utility model is that the use of six inclined columns connected between the building platform and the pontoon can improve the rigidity of the middle part of the main hull of the large-scale semi-submersible platform, increase the waterline area in the operating state and reduce the migration resistance. The pontoon is wedge-shaped, which can reduce the corresponding movement amplitude of the offshore platform. The two heave plates can be connected to the water through the truss, so as to increase the balance of the pontoon on the water surface. The pontoon and the building platform are connected by inclined columns, so that the building platform has a better draft depth, and the building platform is prevented from being submerged under the water due to excessive load. The pontoon adopts a wedge-shaped design to reduce resistance when moving, facilitate better movement, and have better flexibility. BRIEF DESCRIPTION OF THE DRAWINGS
