3. Onshore Projects
Complete understanding of delivered pipe
geometry e.g. size and ovality, with instant
access to results
The ability to discuss and negotiate with
welders, acceptance of pipe geometry prior to
pipe being laid
The possibility to discuss with the pipe mill the
delivered pipe dimensions in comparison with
the specification before signing off on the
delivery
National Grid
9 systems measuring over 30,000 pipes in 4
locations throughout the UK
4. Offshore Projects
Steel Catenary Risers and other similar
pipelines where the Hi/Lo tolerance
mismatch must be less than 0.5 mm.
End matching pipe ends including rotational
requirements
Sorting of pipes into size categories group to
determine counterbore settings to avoid
compromising wall thickness criteria
2000 inside & outside measurements
6. Measurement accuracy
Precision engineered instrument body
Sensors
Distance - +/- 0.05 mm
Angle - 0.18 degrees
Inclinometer – 0.3 degrees
Datum estimation – spirit level
Calibration – on site calibration to nominal size ring
Verification – check calibration ring
7. Throughput
OMS design for high speed operation with no
loss of accuracy
Simple operation to avoid operator fatigue
Depending of requirements:
400 pipe ends per 12 hour shift (3-4 operators)
200 pipe ends per 12 hour shift (2 operators)
100 pipe ends per 8-12 hour shift (1 operator) for small jobs
(typically 1-2 days)
8. Service Quality Control
Simplicity of operation
Input data checks and double checks
Visual checks
Calibration checks
Built in traceability - calibration rings
Verification checks
Quality of data is of paramount importance
9. Tool Reliability
Proven design
Robust over-engineering for sustained use
Low power consumption
Stock kept of critical components, back up tools
available when required
Complete back up of systems components at base
Service history of tool useage
Design constantly updated to incorporate lessons
learned on projects
10. Summary
Pipe end dimension measurement service can measure
pipes sizes from 150 to 1000 mm internal diameter
Equipment is quick to operate resulting in less time on
site with fast project completion
The accuracy and traceability of the OMS tools is
suitable for all uses
OMS can mobilise very quickly to any location in the
world
