| 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). |
