Optimization of monopiles for offshore wind turbines.
The offshore wind industry currently relies on subsidy schemes to be competitive with fossil-fuel-based energy sources. For the wind industry to survive, it is vital that costs are significantly reduced for future projects. This can be partly achieved by introducing new technologies and partly through optimization of existing technologies and design methods. One of the areas where costs can be ...
متن کاملNew Guideline for offshore wind turbines
The offshore wind energy market is developing fast. Turbines, substations and offshore sites are increasing in size and they are in more challenging environments. Therefore, the industry requires vigilance in maintaining standards to keep pace with technology developments, enabling safe deployment and long term operation. Certification of wind farms, wind turbines and their components is state-...
متن کاملStructural dynamics of wind turbines
Structural dynamics of wind turbines aims at assessing the integrity and reliability of the complete construction against varying external loading over the targeted life time. Since wind induced excitation is the most important, structural dynamics is closely connected to aeroelasticity. Most of structural analysis is based on modelling while tests are reserved for prototype assessment. To this...
متن کاملHigh-fidelity Modeling of Local Effects of Damage for Derated Offshore Wind Turbines
Offshore wind power production is an attractive clean energy option, but the difficulty of access can lead to expensive and rare opportunities for maintenance. As part of the Structural Health and Prognostics Management (SHPM) project at Sandia National Laboratories, smart loads management (controls) are investigated for their potential to increase the fatigue life of offshore wind turbine roto...
متن کاملReducing Uncertainty of Monte Carlo Estimated Fatigue Damage in Offshore Wind Turbines Using FORM
Uncertainties related to fatigue damage estimation of non-linear systems are highly dependent on the tail behaviour and extreme values of the stress range distribution. By using a combination of the First Order Reliability Method (FORM) and Monte Carlo simulations (MCS), the accuracy of the fatigue estimations may be improved for the same computational efforts. The method is applied to a bottom...
