Ship superstructures are commonly manufactured from steel but composite sandwich structures could be an alternative leading to significant weight savings. In addition to these weight savings using sustainable materials could reduce the environmental impact of ship production, operation and recyclability in shipping. However, these materials must be capable of equal performance to those that are currently used. Comparing sandwich panels is complex as there are many objectives, stress to strength ratio, sustainability, cost and mass, and variables such as the skin and core materials and thicknesses. Due to this complexity Genetic Algorithms are used to compare potential designs, providing different material selections for different combinations of objectives. The comparison between different Genetic Algorithms demonstrates that HEIA is the most effective algorithm but with all of the algorithms having equivalent performance on these problems. The optimisation provides a set of 716 feasible designs, with balsa being the most popular core but with feasible solutions split between the flax, carbon and glass skins.
