• Early maturity assessment during FEED
• Extensive qualification during detail engineering
• Fluid compatibility testing• Hyper-Elastic law development for FEA• Resistance to explosive decompression• Ageing – stiffening and impact on design • Fatigue resistance under pressure cycles
Flexible Joint Qualification
Early Maturity Assessment defined qualification scope for FJ design
Full scale test confirmed manufacturing process & design fitness for severe conditions
