| Description |
The purpose of this study was to
investigate the non-linear aspects of compliant risers. This is a continuation of
Project No. 92, which considered only linear or first
order effects. The focus was on deriving unified analytic solutions for the non-linear
dynamic response of compliant riser systems to discern the fatigue effects due to fluid
drag and riser-platform interaction. This study was conducted as a Joint Industry Project
(JIP) with several industry participants under the direction of the Massachusetts
Institute of Technology Sea Grant Program. |
| Progress |
Complete. A manual was prepared
to document the computer code developed to analyze compliant riser systems. The computer
program can be used on personal computers, but due to the required storage capacity,
increased accuracy can be obtained using larger systems. |
