Seminar by Dr. Marcin Kapitaniak from the School of Engineering, University of Aberdeen, entitled: "Dynamic response of a shallow-draft floating wind turbine concept: Experiments and modelling", to be held on February 14, 2025 at 9:15 a.m. in auditorium 1M02 in building A22 of the Faculty of Mechanical Engineering has been postponed due to lecteurer illness. New date will be annonced later.
Streszczenie: The nonlinear dynamics of a novel concept of Floating Offshore Wind Turbines (FOWT), able to harvest wind energy in deep-harsh sea waters due to its light-structure design, is investigated under regular sea wave excitations by varying wave height and period parameters to evaluate its heave a pitch system displacements. The system designed by T-Omega Wind is modelled as a multibody structure in CAD and their system’s motions are simulated in a real-time Multiphysics Marine Simulator at The National Decommissioning Centre at the University of Aberdeen. Simulations are performed for “High" and “Low" Sea States to predict the system’s behaviour and calibrated with the system damping coefficients. Simulations are validated with experimental results performed with a 1:60 scaled prototype at the Kelvin Hydrodynamics Laboratory (KHL) of the University of Strathclyde. Moreover, feasibility studies of the system, specific dynamic studies and simulations are performed with a designed towing system, which allows the system to be towed to the port for maintenance. The study identified different types of system dynamical responses while varying wave parameters and proved the model with good experimental results agreement. The study concluded that for this concept first design the system is stable even under harsh-sea excitation states.
