This study investigates the global hull vibration characteristics of a 2,000-ton fisheries training vessel and evaluates its habitability based on the ISO 6954:2000(E) standards. A three-dimensional finite element model, developed using MSC Patran/Nastran, was validated against sea trial measurement data. The results indicate that natural frequencies are generally below 10 Hz and decrease with increasing load. The habitability assessment shows that vibration levels remain at 5-8% of the ISO criteria for the FEA model and 4-10% for the measured data, confirming that the vessel satisfies the regulatory limits. The methodology, validated by these measurements, provides a quantitative technical basis for the design verification and operational management of similar vessels.
