Abstract:Economic reasons have motivated shipyards to look for new lightweight solutions. Going below the 5-mm plate thickness limit set by the classification societies for the superstructure decks of cruise ships could be one way to achieve the goal. However, the fatigue design of such large thin welded structures is challenging because of the higher initial production-induced distortions. Additionally, the fatigue assessment methods used for thicker welded plates are not fully validated for thinner ones.
