Vessels superstructures are traditionally made of metallic materials. Within the RAMSSES project, the objective is to develop and apply a digital / experimental approach to introduce innovative composite materials in naval applications. The main challenges of the project are to: reduce the weight of structures, reduce ownership and acquisition costs, improve the fire behavior of composites materials, develop functionalized composite structures (integration of fire insulation and sensors in the bulkheads) or even design, develop and qualify multi-material assemblies.
This article aims to describe the methodology used to qualify a composite material superstructure block made of composite materials for a ship whose tonnage exceeds 500UMS. Beyond the developments carried out on multi-material junctions and the functionalization of composites materials, this article explains the regulatory process applied (according to actual BV rules and IMO SOLAS circulars) to be able to integrate such structures on board.
