摘要：This study briefly presents MIRBA (Methodology for Investigation of Risk Based Maintenance) formobile mooring system. MIRBA is developed based on bow tie analysis and AHP. Bow tie analysis consistsof FTA (Fault Tree Analysis) on left part and ETA (Event Tree Analysis) on the right part. FTA is useful todetermine the potential causes from critical top event until the undesired events are obtained. ETA (Event TreeAnalysis) is helpful to define the possible consequence by relating an initiating event to various consequencemodels. MIRBA consists of risk management through bow tie analysis, risk mitigation by developing themitigation plan and risk based maintenance using AHP. MIRBA is aimed to provide a guidance on systematicmethodology of risk based decision making which is useful to manage and reduce the risk for offshoreplatforms.
