| With the continuous development of modern society, the development and utilization of marine resources is increasingly urgent.Our country has vast territorial water, which contains rich marine resources. In the field of deep sea, the development of energy is bound to have the important influence on the future energy development, Semi-submersible offshore platform has the advantage of other forms of platforms which have no the advantage. It has a strong ability to resist wind It also has large deck area and reproduced capacity, operation efficiency and good performance characteristics such as motion. However, the construction of a semi-submersible drilling platform are limited by the precision, construction environment and other conditions, which restricts international competitiveness of the semi-submersible drilling platform. Analysing the semi-submersible drilling platform construction, summarizing the construction rules and analysing the influence of various factors have important practical significance on the development of the marine engineering in our country.The text is based on A5000semi-submersible offshore oil drilling platform construction, combining with the construction of block, block assembly It describes the A5000semi-submersible offshore oil drilling platform construction process in detail, summarizes the construction rules of semi-submersible drilling platform and describes precision control and the main points of the process and analysis the main influencing factors. According to combination with field work practice, referencing lessons from the experience of predecessors, we determine the standard rules of production for semi-submersible drilling platform, and summarize precision control methods. The analysis of influence factors and difficulties of the construction provide experience for our country’s construction of the semi-submersible drilling platform, which make the whole project quality improved, for example, the technological and innovation. At the same time, it esFiglished the mode of some technical managements and accuracy control. |
