Reliability 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 کاملSoil–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 کاملRefined Fatigue Analysis for Tripod Support Structure of Offshore Wind Turbine (OWT)
Fatigue design and certification of OWT is a special challenge. As the turbine manufacturers are reluctant to share detailed turbines information and the offshore contractors have not full knowledge of integrated OWT design, integrated and non-linear time domain simulations are too cumbersome. A simplified approach is proposed, that requires complete separation between turbine and support struc...
متن کاملFatigue reliability analysis of jacket-type offshore wind turbine considering inspection and repair
In this paper prediction of the fatigue reliability of a fixed jacket offshore wind turbine designed for a North Sea site in a water depth of 70 m is performed. The longterm statistical distribution of stress ranges of tubular joints is obtained by combination of time domain simulation for representative sea states. The load histories are normalised to ensure that fatigue design criteria based ...
متن کاملFatigue Reliability of joint connections in support structure of offshore wind turbines
Fatigue Reliability of joint connections in support structure of offshore wind turbines by Anh Quang Mai This study is my initial attempt to investigate the evolution of fatigue reliability of welded joints in offshore wind turbine support structures. This information is crucial to update the inspected data (crack sizes, probability of crack detection) to make the plan for the next inspection a...
