High pressure drilling riser
SRP has developed a number of large diameter flange designs for high pressure riser applications, including shallow water jack-up and deepwater dry-tree drilling risers.
All SRP’s designs are independently verified to comply with the requirements of API RP 2RD or ISO 13628-7 in terms of material utilisation limits and sealing capacity. Optimised designs are available with enhanced bending capacity and sealing performance in dynamically loaded applications.
SRP’s proprietary flange designs have seen extensive use in the North Sea since 2008 in different drilling risers in applications to 15,000psi working pressure.
Through experience gained in developing and running high-pressure riser systems in the North Sea with sister company Claxton, SRP can offer several design features for faster running and reliable make-up. Typical features include:
- Full 3D finite element analysis (FEA)
- Fatigue qualification testing and FEA correlation
- Fastener and bolt tensioning designs for easy spidering and faster rig floor handling
- Internal handling grooves for remotely operated running tool
- A range of metal sealing options based on industry standard and wellhead bore seals.
Delivered by SRP
SRP specialises in fatigue loaded applications, including risers and moorings; high strength steel components and welding. Its expertise also extends to general subsea engineering, equipment integration, quality control and procurement – all skills developed from a heritage in subsea high-pressure riser supply.
