Ultralarge seaborne steel structure floating body capable of autonomously navigating and manufacturing method thereof

Abstract

The invention discloses an ultralarge seaborne steel structure floating body capable of autonomously navigating and a manufacturing method thereof. The steel structure floating body comprises a bottom floating body, a middle supporting frame structure and a top platform structure, the middle supporting frame structure is fixed to the upper surface of the bottom floating body, and the top platform structure is fixed to the middle supporting frame structure. The ultralarge seaborne steel structure floating body has the advantages that the technology of making the single floating body enter the water is adopted, water entrance of the large-diameter overlength floating body becomes simple and easy, the water entrance process is safe and controllable, and water entrance cost is smaller than that of other methods; the position of the floating body and the like in the state of water surface floating is more easy to adjust, and the investment for constructing a large-scale dockage and crane is avoided; the green codeless assembly patent technology is comprehensively adopted in the whole assembly process, a series of unnecessary auxiliary assembly work such as compression code assembly welding, cutting and polishing is omitted, the assembly efficiency is improved by 3-5 times or more compared with existing ship assembly and construction, and the construction cycle of the whole project is substantially shortened.

Description

technical field [0001] The invention relates to an offshore steel structure and a manufacturing method thereof, in particular to a large steel structure capable of autonomous navigation and a manufacturing method thereof. Background technique [0002] The offshore floating platform has good stability in the operating wave environment, and can provide a large-span operating space at sea, such as: floating airports, integrated offshore bases, etc. Due to the limitation of the manufacturing method, the floating platform of the prior art has a small construction area. For an ultra-large offshore floating platform, such as: a super-large offshore floating platform with a length of 1000 meters and a width of 100 meters, the existing technology cannot complete the construction at one time, and Large docks and hoisting equipment need to be utilized during the construction process, resulting in low work efficiency and high production costs. Contents of the invention [0003] In or...
