| Abstract: | The main ice type, Crushing ice, in Liaodong Bay, is chosen for analysing the vibration performance of offshore structures. The calculated frequencies of the third mode of either the production platform or the ice measuring platform are in full agreement with the measured ones in situ. The responses of displacement, speed and acceleration as well the stress in the structures are calculated and some important results useful for both design and operation of offshore structures under sea ice environment are obtained. |
