Probabilistic based design for connecting links in single point mooring system subjected to dynamic spectral fatigue line tension

Structural reliability theory has been applied to design structural members. A major goal is to achieve a balance between safety and cost (or weight) for a given safety level. It is therefore desirable that optimum design is achieved through probabilistic based design procedures. This study is conce...
