Problems solved by technology
Therefore, the traditional ship shape design is usually achieved by changing the length, width, draft and other indicators of the hull, but these changes can only slightly improve the sailing characteristics of the ship to a certain extent, and the designed hull still has large resistance and power consumption. There are many phenomena, especially when the hull is in the coupling of longitudinal roll and lateral roll, the comfort of the ship is very poor, that is, the seakeeping is not good, and the seaworthiness of the ship is reduced

The invention discloses a method of a manufacturing technology of an ultra-deep large cylinder-shaped drilling platform main hull, which comprises the following steps: division of construction stage of the cylinder-shaped drilling platform main hull, construction of double bottom total stage, manufacturing folding of a cylinder body, folding of deck section, and carry and hoisting of superstructure. The invention is provided with a platform structure for strengthening the whole resistance, can be applicable to various marine environments, is free from changing navigation bearing with the wind, has better stability, and can achieve the safety level of preventing immeasurable wind waves.
Description
Technical field: [0001] The invention relates to the field of marine engineering equipment and large-scale ship product manufacturing, in particular to a manufacturing process method for the main hull of an ultra-deep sea large cylindrical drilling platform. Background technique: [0002] The offshore oil and gas engineering equipment industry is a strategic industry that is directly related to the development of offshore oil and gas resources and affects the country’s energy stability and economic security. Offshore oil and gas engineering equipment has become a new growth point in the profitability of the shipbuilding industry and has become the target of competition for major maritime countries. The structure of the platform is complex, bulky, expensive, and high-tech. The marine environment it is in is very complex and harsh. Wind, waves, ocean currents, sea ice and tides act on the platform structure from time to time, and are also threatened by earthquakes and tsunamis. In ...
