This information paper does not prescribe the methodology for developing an FMEA. Instead, it prescribes a standardised format for presenting information relevant to the vessel’s DP redundancy concept. This aims to facilitate an objective and effective assurance process. The information provided should be based on the vessel’s verified design documentation.
