State of the Art
The use of non-metallic lightweight structures for critical applications in SOLAS ships remains very limited despite several successful technology demonstrations. Tincludes recent advances in fields such as biocomposites and fire-retardant materials. However, relevant industry test data is lacking to support the use of such materials in maritime applications. Furthermore, production, assembly and outfitting processes are not sufficiently developed for shipyard needs. As such, steel structures continue to dominate.
Solution
Sustainable lightweight components using bio-based and other innovative materials will be assessed for maritime use. These will integrate a range of functionality including reduced weight, equivalent fire safety (to steel), and improved thermal and acoustic insulation. The development will focus on the up-scaled production of panel-based structures, including connecting and outfitting elements for efficient assembly and installation. The target fire class is up to A-60 and B-30 (minutes to withstand fire), with a thermal conductivity < 0.4 W/mK, and a weighted sound reduction index > 38 dB.
Potential
A wide range of applications in ships (decks, bulkheads, walls) and offshore. Potential also in rail vehicles and buildings. Significant greening potential through bio-based and recyclable/reusable materials and components.
