Probabilistic modelling of geotechnical conditions for offshore wind turbine support structures [PDF]

open access: yes, 2014
The geotechnical conditions of the soil can fluctuate greatly across the wind farm. This is an issue since geotechnical modelling is the base of the structural design of an offshore wind farm, and the efficient installation of the wind turbines ...

Operational strategies for offshore wind turbines to mitigate failure rate uncertainty on operational costs and revenue

open access: yes, 2014
Several operational strategies for offshore wind farms have been established and explored in order to improve understanding of operational costs with a focus on heavy lift vessel strategies. Additionally, an investigation into the uncertainty surrounding

How emerging market firms learn to lead in complex product systems: Evidence from China's civil aircraft industry

open access: yesGlobal Strategy Journal, EarlyView.
Abstract Research Summary The rise of emerging market lead firms (LFs) in global value chains (GVCs) challenges the prevailing view that only multinational corporations (MNCs) from advanced economies lead systems integration, design, and innovation activities.

Study on Dynamic Response of Offshore Wind Turbine Structure Under Typhoon

open access: yesPolish Maritime Research, 2022
Floating offshore wind turbines are easily affected by typhoons in the deep sea, which may cause serious damage to their structure. Therefore, it is necessary to study further the dynamic response of wind turbine structures under typhoons.

The X-Rotor Offshore Wind Turbine Concept [PDF]

open access: yesJournal of Physics: Conference Series, 2019
Abstract The following paper provides an overview of a novel wind turbine concept known as the X-Rotor Offshore Wind Turbine. The X-Rotor is a new wind turbine concept that aims to reduce the cost of energy from offshore wind. Cost reductions are achieved through reduced capital costs and reduced maintenance costs.

Application of Electrical Resistance Probes for Corrosion Monitoring and Cathodic Protection Assessment of Offshore Structures

open access: yesMaterials and Corrosion, EarlyView.
A novel thick‐track electrical resistance probe with five sensing tracks was developed for offshore corrosion monitoring. The probe provides reliable, real‐time corrosion‐rate measurements in natural seawater. Corrosion‐rate trends showed strong agreement with weight‐loss coupon measurements.

Quantifying the hurricane risk to offshore wind turbines [PDF]

open access: yesProceedings of the National Academy of Sciences, 2012
The U.S. Department of Energy has estimated that if the United States is to generate 20% of its electricity from wind, over 50 GW will be required from shallow offshore turbines. Hurricanes are a potential risk to these turbines. Turbine tower buckling has been observed in typhoons, but no offshore wind turbines have yet been built in the United States.

Interaction Between Vortex‐Induced Vibrations and Base Vibrations in Piezoelectric Harvesters

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In the present era, powering sensors using green energy is a significant challenge. One promising solution for the power supply of small sensors relies on piezoelectric energy harvesters excited by vortex‐induced vibrations (VIVs) generated by wind.
