RISJump Bifurcation Phenomenon During Varying Wind Speeds in Floating Offshore Wind Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Floating offshore wind turbines (FOWTs) are susceptible to instability which has come to be called negative damping. Conventional land-based wind turbine controllers when used with FOWTs may cause large-amplitude platform ...
A Comparative Assessment of Simplified Models for Simulating Parametric Roll
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The motion of a ship/offshore platform at sea is governed by a coupled set of nonlinear differential equations. In general, analytical solutions for such systems do not exist and recourse is taken to time-domain simulations ...
Suppression of Irregular Frequency Effect in Hydrodynamic Problems and Free-Surface Singularity Treatment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multibody operations are routinely performed in offshore activities, for example, the floating liquefied natural gas (FLNG) and liquefied natural gas carrier (LNGC) side-by-side offloading case. To understand the phenomenon ...
Development of Coupled Program fast-simdyn and Study of Non-Linear Hydrodynamics, Coupled With Negative Damping and Aerodynamics of Floating Offshore Wind Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Non-linear hydrostatic and wave forces on floating structures are very important during large amplitude waves. The computer program simdyn is a blended time domain program developed by Marine Dynamics Laboratory at TAMU ...
