(Corrosion) Fatigue of Offshore structures

The purpose of this project is to provide insight on the fatigue performance of modern materials, welds, and structures with respect to the area of offshore application and through model development and a general reduction of model uncertainties to enable more reliable and cost efficient fatigue design, maintenance, and repair. In order to fully exploit the potentials of fatigue design, maintenance, and repair, efficient and advanced fatigue test programs need to be conducted and evaluated, new fatigue design formats developed, current design guidelines adapted to new test results, and the fatigue performance over the service life and structural integrity management integrally assessed. The establishment of new design formats and experimental investigations of corrosion fatigue in offshore structures, however, is a formidable task. Thus, the task at hand will in the current project be limited to demonstrate the advantages of advanced material testing and modelling in the framework of risk-based inspection planning.
