Provided the significant contribution of support structures to the capital expenditures of offshore wind, optimisation schemes are often developed to address the need for tailored design of different structures in one farm. A crucial aspect of them is, among others, the Fatigue Limit State (FLS)1234 .To this direction, research is conducted on the response of the structure to cyclic loading in the frequency-domain567 . However, the complexity and the need for advanced software (finite element and/or aero-elastic codes) often limit the flexibility. As a consequence, the design process is not facilitated significantly. The focus of this study is principally placed on the impact that variations in an offshore wind farm (OWF) have on the support structures, particularly on their resistance to cumulative damage caused by wind and wave loading. The vital requirement is therefore that the procedure is computationally affordable to ensure applicability for the early design phase of multiple structures. The goal of this study is to develop such a procedure. |
