6. Fit up Visualisation summary
Why 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?
Proven tools, software and services

10. Internal Weld Scanning
Why perform internal weld scanning?
Elimination of weld defects
Reduction in cut outs at AUT station
Contract requirement
Why OMS Tool?
Fast, extremely high quality images, accurate, recordable
data
When to inspect internal welds?
After welding of DJ, in firing-line after hot-pass, in JLay tower,
at stalk tie-in
- 28 -
15. Counterbore Planning
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

17. Bevel Checking
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
- 10 -
19. Pipe Straightness
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 use OMS tools?
Fast, accurate, repeatable, traceable, easy to use
When are pipes checked for straightness?
Before and after welding and after spooling
- 12 -
21. Pipe End Squareness
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
When are pipe ends checked for squareness?
Following the bevelling station

23. ID HiLo Closed Gap
Why measure ID Closed Gap Hi-Lo?
Longer fatigue life
Less likelihood of a Hi-Lo problem related cut out
Contract requirement
Why use OMS tools?
Faster, accurate, repeatable, traceable
When are ID Hi-Lo’s measured ?
Directly before welding
- 17 -
25. ID HiLo Open Gap
Why measure ID Hi-Lo?
Longer fatigue life
Less likelihood of a Hi-Lo problem related cut out
Contract requirement
Why use OMS tools?
Faster, accurate, repeatable, traceable, lasting record
When are ID Hi-Lo’s measured ?
Directly before welding

28. Weld Flushing
Measure the depth to
which the weld is
ground off
Gauge mounted on
movable carriage to
measure across the
weld zone
Magnetic mount to pipe

29. Weld Flushing
Why measure weld cap height and flushing?
Reporting to client
Stronger weld
Contract compliance
Why use OMS tool?
Accurate direct measurements, traceable, repeatable
When to measure weld cap flushing?
After grinding before AUT inspection
