4.1.1. Preparation Step

To implement FMEA, it is necessary to examine the criteria applied to each power source and hybrid power system configured in the test bed. As a marine fuel cell was applied to an Eidesvik Offshore support vessel of, this study collected and referenced safety-related data such as fuel supply facilities, fire protection facilities, and ventilation systems. This study also examined the "Guidance for Fuel Cell Systems on Board of Ships" published in the Korean Register of Shipping, the "Approval in principle fuel cell installation for LNG Tanker" standard, and the "Guideline for the use of fuel cell systems on board of ships and boats" published in the Det Norske Veritas-Germanischer Lloyd (DNV-GL) registrar [38].

The FMEA worksheet, an important component of FMEA, should be confirmed before performing FMEA. S classification, one of the items in the worksheet, is particularly important; this should be completed with reference to Table 1, which indicates the severity class presented in IMCA M 166 [39].
