Soil–structure reliability of offshore wind turbine monopile foundations
An overview of offshore wind turbine (OWT) foundations is presented, focusing primarily on the monopile foundation. The uncertainty in offshore soil conditions as well as random wind and wave loading is currently treated with a deterministic design procedure, though some standards allow engineers to use a probability-based approach. Laterally loaded monopile foundations are typically designed u...
متن کاملSoil-Structure Modeling and Design Considerations for Offshore Wind Turbine Monopile Foundations
The contribution of foundation damping to offshore wind turbines (OWTs) is not well known, though researchers have back-calculated foundation damping from “rotor-stop” tests after estimating aerodynamic, hydrodynamic, and structural damping with numerical models. Because design guidelines do not currently recommend methods for determining foundation damping, it is typically neglected. This pape...
متن کاملReliability analysis of monopile offshore wind turbine support structures
We probe the reliability of monopile support structures designed to support industrial scale turbines along the coastal United States using stochastic models for the wind and wave loadings, and representations of the uncertainty associated with soil properties. The turbine support structure investigated is that promulgated by the National Renewable Energy Laboratory as typical of a monopile sup...
متن کاملCrack Monitoring of Operational Wind Turbine Foundations
The degradation of onshore, reinforced-concrete wind turbine foundations is usually assessed via above-ground inspections, or through lengthy excavation campaigns that suspend wind power generation. Foundation cracks can and do occur below ground level, and while sustained measurements of crack behaviour could be used to quantify the risk of water ingress and reinforcement corrosion, these crac...
متن کاملWind Turbine Testing Control System
The main greenhouse gases (GHGs) producer is represented by the fossil burning systems. The paper presents the effect on the GHGs emission combined with the economic effects of a new pumping system method of automatic mixing of hot and cold water circulated with variable speed driving pumps and adjustable vanes. Considering the potential economic and environmental effects combined with the soci...
