| Description |
For the safety of
an FPSO in survival conditions, it is important to accurately predict any
extreme response and the maximum mooring tension during a storm. This study
will examine a mooring/riser dynamic analysis program and compare its
predictions with OTRC experiments. |
| Progress |
The PI, Kim et al. has
developed powerful software called WINPOST for hull/mooring/riser nonlinear
coupled dynamic analysis in time domain. Program has been extensively tested
and verified against experimental results for various kinds of Spars and
TLPs. WINPOST has since been extended to turret-moored FPSO analysis
including large yaw motions, and successfully compared against other Deep
Star FPSO results and Marin's experiments. Further testing has been extended
to handle FPSO-shuttle combinations both in tandem and side-by-side mooring
cases. This now in development will be verified against future OTRC
experiments. It is anticipated to handle more complicated multi-body systems
with more complicated combinations of mooring lines, such as Spar/TLP-drilling
barge-FPU combinations.
The project was completed on December 08, 2004.
