This is a
recently completed ABAQUS model of a φmax=6370 mm conical reduction,
for which PROMEC provided the design basis ASME stress analysis for a
large manufacturer. The column support skirt is welded to the
conical reduction. Because of the column height, pressure stresses were
excessively high in the hydro test condition, and traditional vessel
design software was not well suited to the task. Several analysis
iterations and physical modifications were evaluated before converging on
this arrangement, which meets all VSR ed. 99 material stress limits,
although a Division 2 design by analysis approach was utilized.
