The current study outlines a novel multimodal structural reliability methodology, suitable for naval dynamic systems, that are either numerically simulated, or directly physically measured. Cross-correlations between the system's principal/key dimensions/components, along with high dimensionality of complex not easily addressed by existing methods, mostly univariate bivariate. objective this had been to apply reliability/hazard assessment methodology UIKKU chemical tanker onboard measurements demonstrate efficiency proposed methodology. Current investigation utilized measured ice loadings, exerted on hull and propulsion devices during its Arctic voyage. Onboard data recordings then were interpreted gain knowledge about load levels. instrumented so ice-induced loads/stresses vessel shell plating monitored at various key locations, both in longitudinal as well vertical directions, vessel's hull. Longitudinal bending stresses several locations accelerations analyze global behaviour when colliding e.g., moderately heavy ridges. In addition onboard, Russian partners icebreaker Capitan Dranitsyn real-time measure strains/stresses within belt grillage, located bow. Icebreaker acted escort whole Obtained results may be harmonize IACS Polar ship rules. study, measuring system results, voyage have briefly represented.
