Flexible cylindrical structures are susceptible to the concomitant excitation of vortex-induced
vibration (VIV) and time-varying axial tension in offshore engineering. The structural …

This paper addresses a detailed literature review on non-linear modes of vibration and its
role in obtaining more efficient reduced-order models, as compared to those obtained by …

A deep sea mining system has been proposed as a way to overcome a future shortage of
resources. A vertical transport system (VTS), as the key component for deep sea mining, is …

The surge and heave motions of the floating platform have a non-negligible effect on vortex-
induced vibration (VIV) of marine risers, which generates time-varying axial tension of risers …

In the context of challenging scenarios for offshore oil exploitation, robust numerical models
are necessary to predict the risers' mechanical behavior. This work presents a model to …

In offshore engineering long slender risers are simultaneously subjected to both axial and
transverse excitations. The axial load is the fluctuating top tension which is induced by the …

An experimental investigation of concomitant Vortex-Induced Vibration (VIV) and top-motion
excitation with a long and vertical flexible cylinder is presented. Underwater optical …

This paper focuses on the analysis of the parametric excitation of a vertical and immersed
flexible rod, showing the influence of the choice of the shape function used in the Galerkin's …

Parametric resonance is one of the key topics in studying the dynamics of structures. In this
paper, dynamic analysis of rotating beams with varying rotational speed in the presence of …

A top-tensioned riser is a slender pipe that conveys fluids between a floater and a subsea
system. High top-tension keeps its straight configuration and helps to prevent compressive …
