Abstract
Floating wind is developing rapidly, and shared mooring systems are one possible solution to reduce costs by reducing the number of mooring lines and anchors per wind turbine. Most research on shared systems is focused on intact configurations, with limited focus on degraded states such as accidental line breaks. The interconnected nature of shared systems makes early assessment of accidental line break essential, and this work presents an efficient low‑fidelity method for early‑stage evaluation of the consequences of accidental line breaks in shared mooring systems. The method supports comparative assessment of different mooring systems, power‑cable layouts, and power production strategies in damaged states, based on static analyses and reliability analyses.
