Slow-drift motion: Practical estimation of mooring line damping
Abstract
A simple method is presented, that permits to calculate the slow-drift damping induced by mooring lines. It is based on a linearization of the catenary line equations. Comparisons are made with experimental results, and with values obtained with a fully non linear code, with a good agreement. An application case is then presented for a storage barge in the Gulf of Guinea, where it is found that mooring lines bring the dominant contribution to the low-frequency damping.
