Application of system identification techniques in efficient modelling of offshore structural response. Part I: Model development
TLDR
In this paper, the response of an offshore structure exposed to Morison wave loading can be approximated by an equivalent finite-memory nonlinear system, which can then be used to determine the probability distribution of response extreme values with great efficiency.About:

Endurance Wave Analysis (EWA) and its application for assessment of offshore structures under extreme waves
TL;DR: In this article, a novel approach, called Endurance Wave Analysis (EWA), is introduced for non-linear dynamic analysis and assessment of offshore structures subjected to irregular wave forces, which is an extension of the Endurance Time Analysis (ETA) already presented by previous researchers for the seismic assessment of onshore structures.

Time series prediction of mooring line top tension by the NARX and Volterra model
Murat Yetkin,Yooil Kim +1 more
TL;DR: In this article, a nonlinear autoregressive with an exogenous input (NARX) technique was introduced with a finite nonlinear memory length to predict the top-tension of a mooring line of the box-type floating production storage and offloading (FPSO).

Comparison of three different methods of moments for derivation of probability distribution parameters
TL;DR: In this article, the authors compare the efficiency of the conventional method of moments with two alternative forms of the method, i.e., linear and low-order methods of moments.

Finite memory quadratic Volterra model for the response prediction of a slender marine structure under a Morison load
TL;DR: In this paper, a nonlinear autoregressive with exogenous input (NARX) technique was used to predict the nonlinear dynamic response of a 2-dimentional free standing catenary riser exposed to a random ocean wave load.

Substructural identification of jack-up platform in time and frequency domains
TL;DR: In this paper, the use of substructural identification and genetic algorithms is explored to address these challenges with focus on offshore jack-up platforms, where both time domain identification and frequency domain identification are both studied for better solutions.

Principal Component Analysis
TL;DR: Principal component analysis (PCA) as discussed by the authors replaces the p original variables by a smaller number, q, of derived variables, the principal components, which are linear combinations of the original variables.
