The FMEA method critically underperforms in this context due to implicit equal weighting, non-unique Risk Priority Number (RPN) mapping, and subjective weight assignment. This study validates an integrated CRITIC-CODAS-FMEA framework, building on our prior application to composite Lenj hulls, by extending robust proof across navigation, refrigeration, and propulsion subsystems of fishing Lenj. Almost all failure modes are analyzed using expert elicitation (n=12 marine specialists). The CRITIC method derives objective weights by quantifying contrast intensity and inter-criterion conflict in S/O/D ratings, while the CODAS method employed Euclidean and Taxicab distances to resolve ranking ambiguities in the weighted space. The framework achieves 100% resolution of identical RPN clusters and elevates 89% of high-severity modes (S&ge;9) into top-10 rankings versus 60% for conventional FMEA. It demonstrated superior alignment with expert consensus (Spearman &rho;=0.87 vs. 0.62) and 92% expert agreement versus 56% for RPN-based prioritization. This framework transforms risk assessment into a context-aware decision tool, objectively capturing marine operational realities to significantly enhance crew safety for the 34.3 million fishers operating worldwide.</span></span> Maritime Safety,FMEA,CRITIC,CODAS,Multi-Criteria Decision Making (MCDM),Fishing Lenj. 61 80 http://ijmt.ir/browse.php?a_code=A-10-54-1&slc_lang=en&sid=1 Esmaeil Shafizadeh e.shafizadeh@aut.ac.ir 10031947532846004632 10031947532846004632 No Department of Maritime Engineering, Amirkabir University of Technology S.
