A novel method in generating freak wave and modulating wave profile
TL;DR: In this paper , the expected freak wave is firstly embedded in an irregular wave train and then transformed into frequency domain by Fast Fourier Transform (FFT), which is helpful to investigate the mechanism of freak wave-structures interaction in deep.

Influence of second-order wave force and focusing position on dynamic responses of tension leg platform under a freak wave
TL;DR: In this paper, the effects of the energy ratio of the focused wave train, number of constituent waves, and parameters of the JONSWAP wave spectrum on the generation probability of freak waves are studied, and the generator probability of the freak wave is fitted by a Γ cumulative probability density function.

Dynamic Response of Articulated Offshore Wind Turbines under Different Water Depths
TL;DR: In this article, three articulated foundations were adopted and numerical simulations were conducted in the time domain to simulate the dynamic response of the articulated offshore wind turbine, where the aerodynamic load on rotating blades and the wind pressure load on tower were calculated based on the blade element momentum theory and the empirical formula, respectively.

Physical Mechanisms of the Rogue Wave Phenomenon
Christian Kharif,Efim Pelinovsky +1 more
TL;DR: A review of physical mechanisms of the rogue wave phenomenon is given in this article, where the authors demonstrate that freak waves may appear in deep and shallow waters and demonstrate that these mechanisms remain valid but should be modified.
Journal ArticleDOI
Oceanic Rogue Waves
TL;DR: In most circumstances, the properties of rogue waves and their probability of occurrence appear to be consistent with second-order random-wave theory as mentioned in this paper, although it is unclear whether these represent measurement errors or statistical flukes, or are caused by physical mechanisms not covered by the model.
