Abstract
Monopiles are the most widely utilized foundation for offshore wind turbines (OWTs) in shallow waters. However, jacket-type foundations are being considered as one of the good alternatives to monopole foundations for relatively deep water in the range of 25–50 m of water depth. Jacket structures are conventionally used in the oil and gas industry. However, there are still several issues unsolved for utilization of jacket structures for OWTs including pile–soil-interaction (PSI) effects, dynamically stable design, installation, and so on. In this study,the effects of pile–soil interaction on the dynamic properties of jacketsupported OWTs are investigated. The jacket structure is modeled as a four-legged multi-member structure with vertical pre-piles, and the PSI effects on dynamic properties of the structure are evaluated using Monte Carlo simulation considering uncertainties in soil properties.
