Floating platform effects on power generation in spar and semisubmersible wind turbines

open access: yesWind Energy, 2021
The design and financing of commercial‐scale floating offshore wind projects require a better understanding of how power generation differs between newer floating turbines and well‐established fixed‐bottom turbines.

Modeling and control of a floating platform

open access: yesIEEE Transactions on Automatic Control, 1994
A platform with a rotating crane resting on three adjustable floats in a tub has been built on laboratory scale. Controller design is studied to prevent the platform from leaning due to crane movements. The system dynamics can be described primarily by a simple sixth order linear model.

Damping analysis of floating offshore wind turbines (FOWTs): a new control strategy reducing the platform vibrations [PDF]

open access: yesWind Energy Science, 2023
In this paper, the coupled dynamics of the floating platform and the wind turbine rotor are analyzed. In particular, the damping is explicitly derived from the coupled equations of the rotor and floating platform. The analysis of the damping leads to the

Analysis of the Dynamic Response of Offshore Floating Wind Power Platforms in Waves

open access: yesPolish Maritime Research, 2020
Floating wind power platforms are in constant motion due to waves when deployed at sea. This motion directly affects the stability and safety of the platform. Therefore, it is very important to study the laws governing the platform’s dynamic response. In

Experimental validation of parked loads for a floating vertical axis wind turbine: wind–wave basin tests [PDF]

open access: yesWind Energy Science
Parked loads are a major design load case for vertical axis wind turbines (VAWTs) because of persistent high loads on the rotor when in standstill conditions.
