ABSTRACT
This chapter examines the parametric Finite Element Analysis model of an Offshore Wind Turbine (OWT) support structure developed in to analyse how different growth rates and patterns of zonation of Marine Growth (MG) affect the structural integrity of the system. OWT support structures are invariably subject to colonisation by marine organisms, which are believed to have an impact on OWTs structural integrity. The validation of the parametric model was carried out comparing the results of the modal analysis of both the structure and the tower, against data from the reference OWT. The chapter analyses the impact that two different MG profiles have in the structure’s integrity and modal frequencies. Tidal currents and wind driven currents are two environmental loads in which MG can have an impact and vice versa. Fatigue is the structural feature most affected by MG, according to the analyses.
