WHAT THE SOFTWARE DOES

Calculates the maximum, minimum, and average hi-lo, CL eccentricity, and SCF
(stress concentration factor) and identifies the corresponding joints
Selects a subset of any desired number of pipe joints that result in the best SCF
Calculates the maximum, minimum, and average hi-lo, CL eccentricity, and SCF of the
selected subset and identifies the corresponding joints
Considers any random joint, any end (to be) welded to any random joint, any end,
based on either the OD or ID and on any desired SCF formula
Example, No. of iterations to determine the hi-lo, eccentricity, and SCF
100 joints: ~40,000
500 joints: ~1,000,000
Example, No. of iterations to select half of the pipe joints with the best SCF
Selecting 50 of 100 joints: ~310,000
Selecting 250 of 500 joints: ~35,000,000
It is nearly impossible to perform this analysis using spreadsheets


EXAMPLE BENEFITS

Verifying that the maximum calculated SCR doesn't exceed the SCF assumed in the
design
Determining the additional margin on fatigue life (if any as per the calculated SCF)
Determining whether machining of the pipe ends is required--eliminating machining
Saves cost
Saves time
Prevents loss of wall thickness (detrimental for strength and ECA in particular)
Eliminates the risk of potential crack starters
Selecting the best joints to send offshore for installation while keeping the rest
onshore for spares (such as a spare riser)
Eliminating the logistics, cost, likely errors, and time of
Pipe joint sorting (certain joints in sequence)
End matching (rotating the joints for best fit)
Selecting the best joints (groups) to put in the high fatigue zones such as the riser
sagbend, hang off, and hog bend
