Dynamic Fatigue Assessment of Fixed Offshore Platform
In this paper a practical method for dynamic fatigue assessment of jacket-type offshore structure is investigated. Fatigue is a primary mode of failure for steel structures that are subjected to dynamic loads. For offshore structures the main source of fatigue inducing stress range are ocean waves....

| description | In this paper a practical method for dynamic fatigue assessment of jacket-type offshore structure is investigated. Fatigue is a primary mode of failure for steel structures that are subjected to dynamic loads. For offshore structures the main source of fatigue inducing stress range are ocean waves. The spectral approach to fatigue analysis is an attempt to account for the random nature of a confused sea in a rational manner. An accurate procedure for the random vibration computation of structure is developed using frequency domain techniques. To illustrate the aforementioned methodology, a jacket type offshore platform in the Persian Gulf has been selected. |
