A lightweight sandwich plate system (SPS) consisted of steel faceplate and polyurethane elastomer composite cores
have excellent potential to be applied on the ship structure. Steel faceplate and polyurethane elastomer (PU) cores
are frequently applied, but PU has a relatively high material cost. More economical material can be achieved by
combining PU with fiberglass as a fiberglass reinforced polyurethane elastomer (FRPU) composite. In this study, the
sandwich consisting of steel faceplate and FRPU composite core material is applied in the tanker side hull by investigating
the structural performance and weight saving analysis using finite element analysis (FEA). Four sandwich
side hull models using different stiffener configurations are compared with the conventional stiffened plate model.
The results show the promising SPS application on structural strength and weight reduction. The remarkable stress
reduction, deformation, and structural weight reduction due to SPS application are discussed. Therefore, its weight
reduction can increase the ship payload so that ship operations will be cost-effective.
The research leading to these results has received financial
