| Abstract: | In this paper,the random variables are introdused based on the principle of Miner's linear cumulative damage. The damage state caused by fatigue in a semi-submersible platform structure is evaluated and a method of reliability analys is in the platform structure suffering fatigue during designed life is presented. An example is given and the significant conclusion is shown. |

| Keywords: | semi-submersible platform fatigue failure random variable reliability study |
