Abstract

The paper presents a parametric study of the design space of a cylinder-like shape floating platform dedicated to multi-megawatt wind turbine. The parametric design architecture considered is a both concrete and sea water ballasted cylinder. It ranges from shallow drafted barge with stability provided by water plane area to slender spar buoy characterized by heavy ballast placed at the bottom of the cylinder. Various configurations are investigated: permanent ballast only or with both dynamic and permanent ballasts, and with or without heave plates. The results show the sensitivity of the system to various parameters in terms of hydrostatic stability, resonance periods, and motion amplitudes.
