Summary

 
The analysis was carried out to evaluate the efficiency of weight reduction for the hull and superstructure of different types of vessels by using large-size light-weight FSW welded panels instead of extruded panels "PК0266". It is revealed that the weight reduction can be achieved by both reduction of panel thickness and increase of frame spacing. The most significant effect of weight reduction, i.e. 23 % is achieved by using large-size light-weight FSW welded panel of 2,5 mm thickness and 400 mm frame spacing instead of extruded panels "PК0266".
