WHY COMPOSITE IN SUPERSTRUCTURES

• Lower structural weight, reduction by >50% ‒ Lower centre of gravity ‒ More pay-load ‒ Higher structure - Equipment higher up • Improved signatures ‒ Reduced Radar Cross Section (RCS) ‒ Lowered IR signature • Integration of sensors in the structure • Less maintenance • Long superstructures without sectioning/gaps COMPANY UNCLASSIFIED | NOT EXPORT CONTROLLED | NOT CLASSIFIED 6 Henrik Johansson | 01-41020236-000 | Issue 00

EXPERIENCE

• Easier with Naval ships than Civilian ‒ Rules and Regulations ‒ Conservatism

• Different level of knowledge

• Training ‒ Engineers ‒ Workers COMPANY UNCLASSIFIED | NOT EXPORT CONTROLLED | NOT CLASSIFIED 15 Henrik Johansson | 01-41020236-000 | Issue 00
