A REDUCED ORDER MODEL FOR THE SIMULATION OFMOORING CABLE DYNAMICS

In this paper the feasibility of a reduced order model (ROM) for thehydroelastic analysis of mooring lines is analysed. The local response of a piece of cableis studied through high delity uid structure interaction (FSI) simulations. The high delity model is built by coupling a computational structural dynamics (CSD) solver witha computational uid 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 astandard CSD solver. From the outside only the beam degrees of freedoms (DOFs) canbe seen, the ROM DOFs are all internal.The local response of the cable is analysed andthe feasibility of the ROM is discussed
