Tahiti Online Monitoring System for Steel Catenary Risers and Flowlines Event: Tahiti Online Monitoring System for Steel Catenary Risers and Flowlines Date: May 2009 Author: W. Ruf, 2H Offshore; M. Podskarbi, Schlumberger; M Karayaka, J. Chen, C. Blankenship, Chevron The Riser and Flowline Monitoring (RFM) project deployed one of the most comprehensive subsea structural monitoring systems to date on a Tahiti infield (production) Steel Catenary Riser (SCR) and associated flowline. State-of-the-art motion and strain measurement devices are optimally placed along the SCR to continuously measure and store real-time full scale riser response. In addition, RFM project is the first to implement monitoring devices on a flowline to measure the flowline buckling a phenomenon that is predicted during repeated start up/shut down. The project goals are two-fold: 1. Understand fundamental hydrodynamic behavior of SCRs and flowlines, specifically, floater motion induced response of catenary risers, Vortex Induced Vibration of catenary risers, riser behavior at the pull tube exit region, riser-soil interaction at the touchdown region, flowline buckling, flowline axial walking, and flow assurance characteristics of infield flowlines. The information generated will be used in future riser designs. 2. The information will be used to validate Tahiti riser and flowline system robustness and conduct “health checks” on the fatigue critical risers and flowlines, particularly after significant environmental or operational events. This paper describes the monitoring system configuration, the technology deployed, and the installation methods.
