Fit up Visualisation summaryWhy Visualise Pipe End Data?
View measurement data for any pipe end
Pipe statistics e.g. Average, Min or Max, Internal and Outer Diameter, Wall Thickness
View simulated fit up of pipes
Best Fit up pipes in spoolbase, on JLay/SLay vessel
Best ID only fit up, or ID and OD fit up
Why OMS?

Why do Counterbore Planning?
Counterboring is required to manage wall thickness
A single counterbore size is not possible due to WT issues
Improved management of welding process
Why OMS?
Experience managing complex multiple SCR projects
When is counterbore planning carried out?
At any stage between pipe manufacture and pipe yard

Why check bevel geometry?
Ensures that bevel geometries are within specification
Documentation of specification compliance
Better welds due to consistent land depths, angles and land thicknesses
Why Use OMS Tools?
Fast, accurate, traceable, repeatable, lasting record
When are bevels checked?
Just after bevelling before the firing line

Why check straightness?
Quantifying pipe bend and hooking
Ensuring the double joints are straight
Proving contract compliance
Ensuring that spooled pipes are straightened correctly without wasting material by checking on deck

Why check end squareness?
Avoidance of out of straight pipe joints
Stress reduction for fatigue senstive pipes
Higher speed welding as time is not wasted rotating pipes to obtain a zero gap
Proof of contract compliance
Why OMS tools?
Fast, accurate, repeatable, traceable, easy to use
