FAILURE PROBABILITY OF SOUTHERN NORTH SEA PLATFORM UNDER ENVIRONMENTAL LOADING

The annual probability of failure due to extreme storm loading is calculated for a manned production platform in the southern North Sea. Statistics of extreme loads are generated from a hindcast study. The fluid loading is calculated using well validated theories for the kinematics of extreme random waves and currents. Non- linear pushover analysis if used to evaluate the ultimate strength of the structure. The likelihood of structural failure is predicted by calculating the probability that the environmental load exceeds the resistance of the structure. Physical uncertainty in the extreme environmental load and the resistance of the structure are treated. These results indicate a very high reliability.
