Experimental and Numerical Investigation into Fatigue and Fracture Assessment of Structures in the Challenging Environments of Deep Oceans
Publication: Earth and Space 2021
ABSTRACT
Estimating the fatigue life of structures in challenging environment is an important factor for both design and maintenance of the asset. Much research has been completed to provide a better estimate of fatigue life of the structure under such extreme loading conditions. However, the uncertainties in the behavior of both the material and the structure have made impractical to provide a real estimate of the fatigue life of the asset. Using extensive field experiments in the Gulf of Mexico, this paper studies the fatigue assessment of structures under deep ocean current profiles. The real VAL stress-time history is used to study the fatigue life of the structure against those calculated based on various numerical fatigue models. It is illustrated that the application of simplified fatigue models that are based on CAL scenarios is nonconservative and has resulted in implementation of high safety factors in the industry.
