Comparative Research on Different Standards of Offshore Steel Structure Platform

Abstract

[Introduction] Wind energy is a renewable energy that has developed rapidly in recent years. The offshore booster station is the key equipment connecting the offshore wind farm and the onshore power grid. It plays the role of collecting and sending wind farm energy and raising the transmission voltage and reducing the transmission loss. At present, the design standards of domestic offshore booster stations are not systematic, and there are many situations where specifications coexist. It is necessary to conduct comparative studies on various standards. [Methods] Firstly, the classification of marine platforms and the classification of design loads were introduced. The design conditions and design methods of offshore platforms in different countries were discussed in detail. Finally, the rationality of earthquake-related correlations was compared and analyzed. [Result] Through the comparative analysis of different standards, there is a situation where ASD method and LRFD method coexist. The design of China′s offshore booster station chooses the route based on LRFD method. With the vigorous development of China′s ocean construction, it will also promote the relevant standards of offshore booster stations and the existing GB. [Conclusion] This study provides an important basis for the selection and rational application of standards.
