State of the Art

A full-scale hull section for a large offshore vessel, operating under harsh environments under SOLAS conditions, including the internal elements, entirely from composite materials, replacing the current steel solution will be developed. While the ‘building blocks’, such as materials, joints and joining techniques or solutions for equivalent fire safety are available from previous research and small-scale applications, solutions have never been combined, tested, validated and approved. Production processes for large composite hull blocks are still too expensive and partly not suitable for practical use under shipyard conditions.

Solution

The aim is to design a complete composite vessel fulfilling SOLAS requirements and class rules, to develop production processes and quality assurance measures and to produce a full-scale hull section (ca. 6m x 6m x 3m). A real-life destructive test will be performed on site under supervision of testing experts, class and flag states. Focus will be on integration of processes and components as well as on understanding and demonstrating real-life behaviour. Design parameters will be validated at real scale to decrease current safety margins. Suitable test procedures, as well as structural health monitoring and calculation methods to gain approval, will be developed.

The demo will result in the first approved fibre-reomforced plastic (FRP) SOLAS ship.

Potential

Dramatic increase of shipyards’ trust, owners, flag states and class societies in the feasibility of composite solutions for large commercial ships; demonstration of a new approach to approval for future cases. Detailed knowledge on processes, design and testing is highly relevant for large load carrying composite structures in various applications, as well as in other sectors.
