Steel catenary riser for the Marlim field FPS P-XVIII
- Petrobras S/A, Rio de Janeiro (Brazil)
Steel catenary risers (SCRs) have been successfully deployed on the Shell Auger TLP in the Gulf of Mexico and will also be deployed on the Shell Mars TLP. There is considerable interest in using SCRs for other applications, in particular for semi-sub based FPS systems. Petrobras is developing an SCR for installation on the P-XVIII platform, located in the Marlim Field, Campos Basin, in a water depth of 910 meters. The riser will be a dead-ended prototype which will be monitored for a period of up to one year. Subsequently, it will be connected via flexible piping to the P-XXVI platform, located approximately 5 kilometers from P-XVIII. This paper describes the design, materials, components, specification and installation of the Petrobras P-XVIII SCR. The static/dynamic design, VIV analysis and fatigue analysis methodologies are discussed in detail and results are presented. Important aspects of the flex joint design and specification are discussed. This project represents the first application of SCRs to semi-sub based FPS systems. In addition, it is the first use of SCRs outside of the Gulf of Mexico.
