The utilization of neural operators in a digital twin model of an offshore floating structure
holds the potential for a significant shift in the prediction of structural responses and health …

This paper presents a novel method for obtaining analytical solutions for the nonstationary
response of multidegree-of-freedom (MDOF) systems endowed with half fractional derivative …

While studying fractional oscillators to the excitation as an evolutionary stochastic process,
this paper develops a novel pole-residue method to compute closed-form solutions for the …

A new fatigue life prediction framework provides an improved life prediction under
statistically and spectrally similar irregular variable-amplitude loading for a notched beam …

Even if ocean waves are treated as a stationary random process, dynamic responses of
floating structures to random waves at the transient state are always nonstationary. When …

Offshore structures have inherently uncertain structure characteristics, which lead to the
uncertainty of barrier levels. Although the uncertainty of barrier levels may affect the …

We developed and tested in real time FIRSTLING-DIGIMAR, a pilot scale digital twin of a
marine riser driven by sparse field measurements. The FIRSTLING consists of hardware and …

Evaluating mean-square response of linear systems to nonstationary excitation has been
extensively studied, but exact closed-form solutions under various assumptions have been …

This article develops a Laplace-frequency method to derive the exact closed-form solution
for the response evolutionary power spectral density (EPSD) of a simple oscillator subjected …

Fixed offshore structures under stochastic loadings usually have time-dependent reliability
due to time-varying statistics of nonstationary load effects. Since closed-form solutions for …
