The use of Very Large Floating Structures (VLFS) could be an alternative solution to the costly good earth fill and the limitations of the environmental concerns when adopting the traditional methods for land reclamation in countries facing issues with land spaces. These flexible floating platforms may be required to be lightweight and studies have shown that the seabed may have influence on the wave propagation. Therefore, this study aimed to model the muddy seabed in reality as a viscoelastic bottom cover, under a viscoelastic top cover, to observe the influences it may have on the cases with different top covers. The conclusion from the analysis of the results showed that different viscoelastic top covers did attenuate or intensify the waves, but was not conclusive to indicate that the different viscoelastic bottom covers had attenuation effects on the waves, as it was insignificant when compared with a rigid bottom. The behaviour of the polydimethylsiloxane (PDMS) should be better studied prior in future, in order to have an effective study when using it as the experiment material.
