REVIEW ON MONOPILE FOUNDATION FOR FIXED OFFSHORE STRUCTURE

Abstract- This paper provides a broad overview of some of the key factors in the design monopile foundation for fixed offshore structure. During the last years, offshore wind turbine structures were reported to settle on the monopile structure and the resulting force flow in the structures was different to that intended at the design stage. A joint industry project was therefore carried out by Det Nordce Veritas (DNV) [1] to investigate the structural capacity of these connections from autumn 2009 to January 2011. It was found that the axial capacity of the grouted connections is a more sensitive function to the diameter and surface tolerances than that accounted for in existing design standards
