TLDR
In this paper, the authors investigated the freak wave impinging on a tension-leg platform through wave flume experiments and found that although applying less intensive local impact pressures as compared to the highly breaking freak wave, the slightly-breaking or non-breaking freak wave imposes the same level of adverse effect on the platform's global stability in terms of motions and tether forces.About:

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.

Investigation of higher-harmonic wave loads and low-frequency resonance response of floating offshore wind turbine under extreme wave groups
TL;DR: In this article , a high-fidelity CFD solver was adopted to obtain the parameters for each harmonic response of a floating offshore wind turbine (FOWT) in extreme marine environment.

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.

Experimental investigation of freak wave actions on a floating platform and effects of the air gap
TL;DR: In this article , the effects of the air gap on wave actions and platform responses on oceanic floating platforms were investigated. But the authors focused on two air-gap conditions (i.e., 0.35 H c and 0.2 H c), where H c is the height of the platform column.

Study on wave slamming characteristics of a typical floating wind turbine under freak waves
TL;DR: In this article , the slamming pressure characteristics of a typical floating wind turbine under freak waves are studied by numerical simulation and experiment using the computational fluid dynamics (CFD) method, which is used to establish the numerical tank.

Experimental study on vortex-induced motions of a semi-submersible platform with four square columns, Part II: Effects of surface waves, external damping and draft condition
TL;DR: In this paper, a semi-submersible platform with four square columns was tested in the presence of regular and irregular waves, both conditions with simultaneous current presence, to understand the wave effects.

Extreme waves in shallow and intermediate water depths
Tom E. Baldock,Chris Swan +1 more
TL;DR: In this paper, the wave components within a random (or irregular) sea state are focused to produce a large transient wave group in shallow and intermediate water depths, and the results show that the near-bed velocities are in good agreement with the second-order solution which includes the long wave (or frequency difference terms) first identified by Longuet-Higgins and Stewart.

Experimental study on kinematics of sea ice floes in regular waves
David McGovern,Wei Bai +1 more
TL;DR: In this paper, the relationship of the motion response of sea ice floes to the floe and wave characteristics was investigated, showing that scale effect, floe size and floe orientation did not affect the heave and surge motion, and the motion observed was notably different to glacial icebergs.

Investigations of offshore breaking wave impacts on a large offshore structure
TL;DR: In this paper, a truncated wall in a wave flume is used to represent a vertical section of an FPSO hull, and four distinct wave impact types are identified for the vertical hull section and are found to be similar in character to those observed for a full depth vertical wall.

An experimental and numerical study of plunging wave impact on a box-shape structure
TL;DR: In this paper, the plunging wave impacts on a box-shape structure are investigated experimentally and numerically, focusing on three typical scenarios with distinct features, i.e., the wave impact occurs after, upon and before wave breaking.
