Composite riser study confirms weight,fatigue benefits

Pros and ConsSLHR OverviewDeeper WatersConclusionComposite materials offer a range of benefits that could improve riser technology.Composites are lightweight and offer high levels of strength.They can be formed into complex shapes and can provide high levels of resistance to fatigue and corrosion.Maintenance needs are relatively low,and they can be installed via reel lay.They also have a low axial and bending stiffness in comparison to steel.On the other hand,composites present a high material cost and have a limited track record offshore,despite wSee more on offshore-magSome results are removed in response to a notice of local law requirement.For more information,please see here.12345NextPipe Dimensions and Properties (Sch 40,Sch 80)Buoyancy Force .C.camera contact lens camera.camera vision system cameras.
