Safety Margin of Structural Member of Offshore Structures Subjected to Wave and Current

摘要

The response of offshore structures subjected to wave and current is given by the summation of the non-deterministic response to wave forces including current effects and the static response to the steady current force. Using the reliability index, this study highlights effects of current on the safety margin of the structural member. The results suggest that the non-deterministic response performs primary role in evaluating the safety margin.
