ROGEO XYZ SERVICE
IN-LINE PRECISION PIPELINE ROUTE MAPPING
AND Strain Analysis
Knowing the accurate position of your pipeline
is crucial for managing your assets in GIS and
for the planning of field activities like maintenance work and field verifications.
If your pipeline is exposed to ground hazards
ROSEN RoGeo XYZ Service is a key element to
assure the pipeline integrity by identifying pipe
movement and bending strain.
Key Advantages
•Easy location of all ROSEN in-line inspection findings,
such as installations, metal loss, cracks, dents and other
anomalies.
•Reduced inspection cost by combination with additional
inspection technologies in one run.
•Highly reliable strain analysis by most accurate centerline
data to comply with industry standards.
•Identification of complex features, e.g. pipe movement
associated with wrinkles or ovality.
•High quality service with certified processes (API 1163),
personnel qualification (ASNT) and equipment (CE, ATEX).
The solution
service options
ROSEN uses latest high precision inertial measurement
units to obtain utmost data quality for the RoGeo XYZ
service. Detailed analysis of the highly accurate centerline
data, to derive pipeline bending, enables reliable strain
analysis.
All aspects from the inspection request to the final report
are covered with the flexibility to choose from various
service options.
•Cleaning – operational and pre inspection
•Speed Control – inspection at high flow rates
•Multi-Diameter – pipelines with varying diameter
•BiDi – single entry pipelines
•Offshore – long distance and high pressure
•Post ILI – data alignment and combined evaluation
•Integrity – RBI, FFP, CGA and dent strain analysis
•ROSOFT – reporting and data management
•ROAIMS – versatile asset integrity software suite
Our well–structured, certified data evaluation process
provides exact pipeline reference coordinates as an
input for an illustrated plan, elevation and distance view.
Furthermore, findings from other inspection can be
geographically referenced with the same high accuracy.
Our versatile software suite ROAIMS easy visualizes the
pipeline route and references additional multiple data sets
like CP, DCVG, CIPS or other pipeline information.

IN-LINE PRECISION PIPELINE ROUTE MAPPING AND Strain Analysis
Bending Strain
Pipeline Movement
Bending occurs when a pipeline is moved away from
its original position. It is detected using XYZ Mapping
inspection technology with an inertial measurement
unit (IMU) which uses high-resolution fiber optic laser
gyroscopes and accelerometers. These three dimensional
coordinates of the entire pipeline, together with specialized
algorithms are applied and used to calculate the basis for
curvature analysis and detection of bending strain. Strain
changes can be monitored comparing XYZ data from
several mapping inspection runs.
IMU technology can be used to detect movement of the
pipeline from its original position due to, for example,
anchor drag, earthquakes or landslides. Pipeline movement
is determined by comparing the change in trajectory of two
mapping inspections by comparing the “as built” trajectory
with the first XYZ inspection, or two successive mapping
inspections performed within a specific number of years.
