| Abstract: | Failure of offshore
petroleum structures under sea ice conditions is investigated in detail by field
observation,iceinduced dynamic analysis and calculations as well as fatigue and fracture tests.
The most important elements causing and redoubling the failure of the structures are pointed
out and the essential cause to the failure is found out.Some specific practices for structural
design,safe employment,inspection and repairation of platforms in sea ice are
established,some related work that should be done are proposed and emphasized also. |

| Keywords: | sea ice petroleum platform vibration fatigue fracture |
