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