ID HiLo graph at current rotation.

OD HiLo graph at current rotation.

These buttons “nudge” the rotation.

Fixed and Free end pipe IDs along with there diameters.

Current rotation from datum Max ID and OD HiLos at the current rotation along with OK/Fail indicators.

Fitup status indicators. See further documentation.

Buttons to automatically select the Best ID, OD or combined fitup rotation.

View measurement data for any pipe endPipe statistics e.g. Average, Min or Max, Internal and Outer Diameter, Wall ThicknessView simulated fit up of pipesBest 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

Internal Weld Scanning

- 27 -

Weld Inspection (Fan Beam)Rotary head allows scanning entire weld around girth

Power/data umbilical

Tool deployment by pushrods or survey tractor

OMS Weld Scanner tool

Laser measurement head, measures profile across weld

High-res camera allows visual inspection of weld

Typical Example Weld

Why perform internal weld scanning?Elimination of weld defectsReduction in cut outs at AUT stationContract 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

Counterbore Planning

- 7 -

Why do Counterbore Planning?Counterboring is required to manage wall thicknessA single counterbore size is not possible due to WT issuesImproved 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

Counterbore Planning

Bevel Checking

Land thickness, depth and angle

- 9 -

Why check bevel geometry?Ensures that bevel geometries are within specificationDocumentation of specification complianceBetter 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

Bevel Checking

- 10 -

Pipe Straightness

Laser unit

Target ‘Graticule’ Retro-reflector

- 11 -

Why check straightness?Quantifying pipe bend and hookingEnsuring the double joints are straightProving contract complianceEnsuring 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

Pipe Straightness

- 12 -

Pipe End Squareness

Digital Dial Gauge

- 13 -

Why check end squareness?Avoidance of out of straight pipe jointsStress reduction for fatigue senstive pipesHigher speed welding as time is not wasted rotating pipes to obtain a zero gapProof of contract compliance

Why OMS tools?Fast, accurate, repeatable, traceable, easy to use

When are pipe ends checked for squareness?Following the bevelling station

Pipe End Squareness

ID Hi-Lo Closed Gap

- 16 -

Why measure ID Closed Gap Hi-Lo?Longer fatigue lifeLess likelihood of a Hi-Lo problem related cut outContract requirement

Why use OMS tools?Faster, accurate, repeatable, traceable

When are ID Hi-Lo’s measured ?Directly before welding

Weld Flushing

- 29 -

Why measure weld cap height and flushing?Reporting to clientStronger weldContract compliance

Why use OMS tool?Accurate direct measurements, traceable, repeatable

When to measure weld cap flushing?After grinding before AUT inspection
