Accurate knowledge of ocean surface waves is crucial for ship design. With the significant advancements in model physics and numerical resources, recent wave hindcast data has potential to provide environmental conditions estimating load design process. To help estimate extreme loads with quantified uncertainty strength assessments structures, this study aims quantify state-of-the-art products. Model was deduced from inter-model comparisons four products after evaluations. For evaluations, buoys distributed over Northwest Atlantic Northeast were used as buoy arrays. In general, all models accurately estimated height Hs. However, condition becomes increase Hs, estimations Hs deviate differ each other. conditions, two consistently showed better performance based on observations both Atlantic. addition mean period Tm02 are also examined study. Although evaluations not often seen previous studies, another parameter because response calculated a function Tm02. Based careful comparisons, it found that underestimate under Hs>10m. The joint probabilities Hs>10m 8s<Tm02<14s further scatter diagram (SDE). Among SDEs products, total number samples varied by 50%, although value close result buoys. significance variation described context estimation structures.
