The statistical characteristics and parameters of loads and resistances are systematically studied for the development of probabilistic limit state design method for steel jacket offshore platforms in the China offshore area.The mean value,standard variance and distribution pattern of resistances and loads in different base periods are presented.The statistical parameters of structural member resistance,selfˉweight,deck live load,and environmental loads such as wind,wave,current and ice,which are drawn on a large amount of observation data of offshore environmental factors,and the design data of platforms in China Bohai Sea form the data set,providing a necessary basis for the calibration of load and resisˉtance factors to realize the reliabilityˉbased design of jacket platform structures.

The mean value, standard variance and distribution pattern of resistances and loads in different base periods are presented.The statistical parameters of structural member resistance, selfˉweight, deck live load, and environmental protection such as wind, wave, current and ice, which are drawn on a large amount of observation data of offshore environmental factors, and the design data of platforms in China Bohai Sea form the data set, providing a necessary basis for the calibration of load and resisˉtance factors to realize the reliability ˉ based design of jacket platform structures.
