Finite element modelling of mooring lines
WebAug 1, 2024 · • Provide data for validation of finite-element models. As OPB fatigue mitigation measures are complex, heavy, and expensive, design optimization greatly benefits from dedicated testing. This is particularly important with a growing trend toward the use of larger mooring chains, beyond the parameters considered during the guidelines ... WebFor many applications, such as modelling mooring lines attached to a vessel, the accuracy of the full finite element representation of the line, whereby it is discretised into individual nodes that each carry degrees of freedom, is not required.Often, the interest lies only in the vessel and the finer details of the forces acting within the mooring lines are …

WebThe finite element method is used to create a one-dimensional flexible cable element for mooring line analysis in three-dimensional space. The comparison with an extensible elastic catenary is made with Fortran90 routines. KEY WORDS: mooring line; nonlinear; extensible; finite element method. INTRODUCTION WebThe response of a caisson in sand is different from its response in clay under pullout force. In this study, three-dimensional finite element (FE) analyses are conducted to calculate the pullout capacity of a suction caisson subjected to various oblique loadings. The FE modeling is performed using Abaqus FE software.
