ABSTRACT

Floating Offshore Wind Turbines (FOWT), due to their geographical location are subjected to strong dynamic loadings originated from external sources such as wind and waves. Consequently, these systems are highly sensitive to a specific range of operational frequencies. If a dynamical system is under resonance conditions, a significant amplification of the dynamic response amplitude is prone to occur. The aim of this work is to study the response of a particular FOWT model with an externally applied periodic force so that the system may reach resonance conditions. The authors make use of a dynamic model described by a set of second order differential equations. Time and frequency domain analysis are performed with a major focus on the response of the system.
