• 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
