Designers have continually sought to reduce the top weight of ships superstructures to improve stability and payload and to prevent fatigue cracking occuring at the ends of superstructures where there is interaction between deck and deckhouse. Solutions have included the use of aluminium and higher strength thin steel plating but this has introduced penalties in cost, fire resistance and weld distortion. This study seeks to find a solution to the problem by taking advantage of the low specific weight, low stiffness and well proven marine performance of fibre reinforced plastics and which also achieves economies both in initial outlay and subsequent through life costs. The study identifies such basics as structural loadings, material options, panel production techniques, assembly and attachment schemes, and the important statutory regulations in respect of fire resistance. It concludes that the concept is both feasible and viable and warrants deeper, essentially practical, exploration. This is presently being undertaken on Phase 2 of the project which will culminate in the production and test of a full size representative structure.
