Why are synthetic fiber mooring lines preferred over steel wire rope in deepwater mooring systems?

Synthetic fiber mooring lines are preferred over steel wire rope in deepwater mooring systems primarily due to their superior weight-to-strength ratio and fatigue performance. In deepwater, the weight of the mooring line itself becomes a significant factor. Steel wire rope is very heavy, and the self-weight of long lengths of steel wire can add substantial tension to the mooring system, reducing the effective holding capacity of the anchors and increasing the load on the floating structure.
