Oil and gas energy is abundant in Arctic region,which has a great exploitation potential.Concrete gravity-based structures have a board future to be installed in the ocean due to its advantages of high degree of integration and exceptional durability.The calculation methods for ice load,wind load,wave load,ocean current load,foundation reaction,and temperature load were provided in the study based on an oil and gas exploration project in the Arctic region.For the load combinations of gravity-based platforms,standards in China Classification Society(CCS),International Organization for Standardization(ISO),Det Norske Veritas(DNV),American Petroleum Institute(API)and European Union(EN)were introduced to select load types.Then the load combination of the project was defined.Besides,the whole-process structural analysis for towage,installation,and on-site service was carried out by finite element method,verifying the reliability of the platform.
