Dynamic Behaviour of a Mono-pile with Skirted Template Structure for Offshore Wind-Power System

Abstract

The purpose of this research is to develop an offshore structural system that may sustain a stronger wave and have better stability. The object of the research is a hybrid type of offshore mono-pile-template structural system, which is more flexible and relatively easier to construct compared to the heavy mass type offshore structural system. It is expected that this hybrid type of supporting structure for an offshore wind-power generation platform will have the flexibility as presented by a typical template structural and yet, consistent properties for supporting function of the structure. Two types of structure are designed for the analytical study, namely, the mono-pile supporting structural system and the hybrid type combined with the mono-pile and the template structure as an outskirt frame system. Both annual regular waves and extreme storm waves of a 100-year return period are applied to the structural system as exerting forces.
