... One key aspect to consider when talking about structural health is the fatigue life of the unit. Traditionally, in the case of FPSOs, fatigue assessment is performed as part of design and verification procedures. However, the continuous fatigue re-assessment based on data coming from operations...

... to the simplification and limitation to provide rational assessment on lifetime structural integrity and efficient design, structural engineers separately apply factors of safety either as reduced allowable stresses or as factored load combinations [ 4 ]. In the fatigue assessment, spectral analysis is widely used...

... Abstract Riser-soil interactions have significant influence on the fatigue assessment of steel catenary risers (SCRs) near the touch down zones (TDZs), and can be critical in realizing a competitive SCR design and in extending a SCR design life. The motivation of the paper is to share...

... with the objective of establishing commonly accepted methods. Different FEA procedures have been studied for making a better prediction of stress ranges of the corroded chain links. The findings from the fatigue testing and FEA will be utilized as basis for further development of the methods for fatigue assessment...

... Abstract Well fatigue assessment is an important aspect of the design and integrity assurance of deepwater riser-well systems. Fatigue damage arises from stress changes in a conductor due to cyclic loading. In practice, the lateral cyclic soil response is typically modeled using Winkler type...
