Investigation of Risk Based Decision Making for Mobile Mooring System

This paper briefly presents the investigation of risk based decision making for mobile mooring system. This paper used bow tie analysis to analyze the risk of mobile mooring failure. Bow tie analysis consists of FTA (Fault Tree Analysis) on left part and ETA (Event Tree Analysis) on the right part. FTA is useful to determine the potential causes from critical top event until the undesired events are obtained. ETA (Event Tree Analysis) is helpful to define the possible consequence by relating an initiating event to various consequence models. The investigation consists of determining the critical hazards of mooring system failure through investigating the root causes, the consequences, and the frequency index.
