Offshore Wind Farms [PDF]

open access: yes, 2020
The coastal zone is the host to many human activities, which have significantly increased in the last decades. However, sea level rise and more frequent storm events severely affect beaches and coastal structures, with negative consequences and dramatic impacts on coastal communities.

Discussions on the Main Electrical Wiring Scheme for a 400 MW Offshore Substation Station

open access: yes南方能源建设, 2019
[Introduction] Offshore wind farms are characterized by long distance from shore, high costs of repair due to vessels involved and weather, long maintenance cycles and the fact that daily operations and maintenance is highly dependent on weather and sea ...

The Effect of the Second-Order Wave Loads on Drift Motion of a Semi-Submersible Floating Offshore Wind Turbine

open access: yesJournal of Marine Science and Engineering, 2020
Floating offshore wind turbines (FOWTs) have been installed in Europe and Japan with relatively modern technology. The installation of floating wind farms in deep water is recommended because the wind speed is stronger and more stable.

Flow Structure around a Multicopter Drone: A Computational Fluid Dynamics Analysis for Sensor Placement Considerations

open access: yesDrones, 2023
This study presents a computational fluid dynamics (CFD) based approach to determine the optimal positioning for an atmospheric turbulence sensor on a rotary-wing uncrewed aerial vehicle (UAV) with X8 configuration. The vertical (zBF) and horizontal (xBF)

The 3 km Norwegian reanalysis (NORA3) – a validation of offshore wind resources in the North Sea and the Norwegian Sea [PDF]

open access: yesWind Energy Science, 2021
We validate a new high-resolution (3 km) numerical mesoscale weather simulation for offshore wind power purposes for the time period 2004–2016 for the North Sea and the Norwegian Sea. The 3 km Norwegian reanalysis (NORA3) is a dynamically downscaled data

Swell impacts on an offshore wind farm in stable boundary layer: wake flow and energy budget analysis [PDF]

open access: yesWind Energy Science
We investigate the impact of swell on wind turbine wakes and the power output of offshore wind farms under stable atmospheric conditions. We conduct large-eddy simulations, and the influence of swell is modeled by incorporating a wave-induced stress term

The economics of offshore wind [PDF]

open access: yesEnergy Policy, 2011
Abstract This paper presents an overview of the main issues associated with the economics of offshore wind. Investment in offshore wind systems has been growing rapidly throughout Europe, and the technology will be essential in meeting EU targets for renewable energy in 2020. Offshore wind suffers from high installation and connection costs, however,
