Offshore Pipeline S-Lay DesignTraditional Method
INPUT PIPELINE BENDING RADIUS & TENSION
1. Try a pipeline bending radius
Draw laybarge, stinger and pipeline model in Auto CAD;
Adjust laybarge and stinger profile to make all the rollers contacting the pipeline;
Read roller supports coordinates and input them to analysis software.
2. Try a value of tension The stress is acceptable?
YESNO
END
PURPOSE
Find an acceptable combination of pipeline bending radius & tension

Offshore Pipeline S-Lay DesignDisadvantages of Traditional Method
DISADVANTAGES
Wasting time and labor;
Can not get the best combination which brings the minimum stress;
For stinger with more than 2 sections, it is difficult to get coordinates of roller supports;
Boring to edit input file of FEA software.
