Abstract

Resilience is an emerging concept in the management of engineering systems, and its application in enhancing the management of mooring systems is particularly valuable. To effectively manage resilience, it is crucial to assess the system's resilience level. This paper proposes a framework consisting of three key indexes: robustness resilience index (ROI), recovery resilience index (REI), and function performance index (FPI). These indexes assess system's technical, organizational, and economic capabilities, respectively. The ROI evaluates the failure process by employing failure modes analysis, while the REI quantifies the recovery process using a recovery model with various spare parts. The FPI introduces a probabilistic approach to measure the system's capacity over time, incorporating short-term and long-term repair actions. An illustrative example of a semisubmersible production system in the South China Sea is developed as a walk-through to validate the effectiveness and applicability of the proposed resilience framework, discussing quantitatively the effect of environment and available spares. Overall resilience is also obtained by radar graph. The findings indicate that the presence of one spare significantly enhances the system's resilience in industrial applications.
