FLIP, FLoating Instrument Platform [PDF]

open access: yes, 1985
A general summation of the construction, operation and potential of the RIP FLIP. FLIP, i.e., FLoating Instrument Platform, is designed as a super-stable open-sea free-floating platform from which to conduct research in the field of physical oceanography.

Reliability of floating foundation concepts for vertical axis wind turbines [PDF]

open access: yes, 2010
Offshore wind turbines are developing at a rapid pace. By far the most common turbine configuration is the HAWT (Horizontal Axis Wind Turbine) and development of these machines is largely centered about drive train and blade issues with some work ...

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.

Numerical Simulation on Aerodynamics of Multi-Element Airfoil with Drooped Spoiler in Ground Effect

open access: yesXibei Gongye Daxue Xuebao, 2019
By using the finite volume method and k-ω SST turbulence model to solve the Reynolds Average Navier-Stokes equation and using the slipping wall to simulate the relative movement of the ground, the ground effect on the aerodynamic characteristic of multi ...

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
