Project Number | 275 |
Date of Summary | May 01, 2000 |
Subject | Riser Reliability Analysis |
Performing Activity | Risk Engineering, Inc |
Principal Investigator | Dr. Gabriel T. Toro |
Contracting Agency | Minerals Management Service |
Estimated Completion | April 1999 |
Description | This JIP was formed
to develop a preliminary model of riser reliability. The insights gained by this model
will be used to generate a road-map for the development of a more refined model of riser
reliability. The preliminary model will also allow the structure and location- specific
reliability results, which will be useful in the evaluation of the reliability inherent in
current designs.The study originally planned to consider both a TLP production riser and a
drilling riser, each in 1000 meters of water. Participants later added a steel caternary
riser (SCR) serving a Floating Production Storage and Offloading (FPSO) unit. The study
will use data from the Ram-Powell project for the TLP portion of the study. Five different
zones in the riser will be evaluated (tensioner assembly, lower stress joint, a joint near
the wave zone, a connector near the wave zone, and a connector near the bottom). The SCR phase of the project was delayed in order for the study to benefit from the results of the HCR riser JIP (Project No. 305 - all participants in this JIP also participate in the HCR riser JIP). |
Progress | The final report is completed. |
