| Abstract: | The ice-induced vibration of ice-resistant platforms is quite intensive.Installation of ice-resistant cone can effectively reduce ice load,but ice-induced vibrations of platforms still exist,so the fatigue life of the platform need be estimated.The method of estimating ice-induced fatigue life of existing platforms is developed based on the safety life design method and field data.For example,the finite element model of JZ20-2MSW platform is built,then average ice-induced fatigue damage and residue life are calculated, which can provide a warrant for owners to repair and reject platforms. |
