The subject of dynamics originated from Sir Isaac Newton's monograph Philosophiæ
Naturalis Principia Mathematica, and Lord Rayleigh paved the way for its further …

In engineering practice, most mechanical and structural systems are modelled as multi-
degree-of-freedom (MDOF) systems such as, eg, the periodic structures. When some …

In this study, the effects of second-order non-linear random waves on the structural response
of slender fixed offshore platforms are investigated based on frequency-domain Volterra …

A jack-up platform, with its particular structure, showed obvious dynamic characteristics
under complex environmental loads in extreme conditions. In this paper, taking a simplified …

The one-dimensional fast Fourier transform (FFT) has been applied extensively to simulate
Gaussian random wave elevations and water particle kinematics. The actual sea …

The influence of wave force linearisation methods on fatigue damage predictions for jack-up
rigs is investigated, using Sesam software as the basis for comparison. The possible risk of …

This paper intends to draw attention to the influence of gravity on the dynamic response and
fatigue damage assessment of offshore structures. In traditional fatigue life calculation, the …

Statistical analysis methods are developed for determining fatigue time to failure for
nonlinear structures when subjected to random loading. The change in the response, as …

The one-dimensional Fast Fourier Transform (FFT) has been extensively applied to
efficiently simulate Gaussian wave elevation and water particle kinematics. The actual sea …

Offshore jackets and towers are examples of lightweight support structures for wind energy
and oil and gas units. However, their reduced weight is obtained at the expense of …
