A reduced order model for the simulation of mooring cable dynamics

Abstract

In this paper the feasibility of a reduced order model (ROM) for the

hydroelastic analysis of mooring lines is analysed. The local response of a piece of cable is studied through high fidelity fluid structure interaction (FSI) simulations. The high fidelity model is built by coupling a computational structural dynamics (CSD) solver with a computational fluid dynamics (CFD) solver using the approach of software components. The ROM is designed in such a way that it can be added to any beam element from a standard CSD solver. From the outside only the beam degrees of freedoms (DOFs) can be seen, the ROM DOFs are all internal.The local response of the cable is analysed and

the feasibility of the ROM is discussed
