TIGF at a glance
In 2005, the Gas & Power business line of TOTAL creates TIGF
TIGF operates :
5 000 km of natural gas transmission pipelines (13% national network),
6 recompression units (100 MW)
5.4 Gm3 underground storage facilities (22% national capacity).
TIGF does not own any gas, but
transports and stores it for others
gas market actors.

The “AMF” decree dated August 4th, 2006 :
 Own a Geographical Information System (GIS) for 2009 with a Technical
Data Base for 2011
 VIGIE
– Visualisation et Information Géographique des Installations
Enterrées (Geographical Visualization and Information of Underground
Installations)

Plan inspections, surveys and mitigations
 OGIC - Outil de Gestion de l’Intégrité des Canalisations
PIMS - Pipeline Integrity Management System
 For TIGF, these are 2 federating projects which shall :

Allow to share data and informations with all users,

Help with decision making

PODS, the heart of VIGIE and OGIC :
Built on V 4.0.2
Experience of many pipeline network operators, mainly oil and gas
Independent of the GIS publishers
Exhaustive description of pipeline networks
3D imaging of events that form or describe the pipeline
Complex work
To collect and indentify all available data
Mainly manual tasks
In few numbers, it’s about :
70 types of various documents used
10 000 documents collected from the Archives
40 000 A4 format scanned
3 years, 65 000 hours (until 20 persons)
Cost : 2 MEUR for the actual Database
Without the pipeline environment (1 MEUR)
Without the survey, inspection, repairs and CP data (for 2011)

What Kind of data in PODS :
Network :
LINES : Pipelines
SITES : Compression station, Valve and Delivery station, Security valve, CP
Data :
Pipe length, weld join, tee, elbow, closure...
Nominal diameter, Wall thickness, Steal grade, coating, MAOP
Dot Class
Crossing (river, road, railroad,...)
Protection (casing, Concrete slab, river weight),
Marker
Building and housing (HI, IGH, ERP, ICPE)
In the future :
Nominal Depth of cover, temperature
Defects, Repairs, Regulatory compliance effects
TIGF PODS Interpretation : PODS 4.0.2
TIGF used the field “X_Guid” in order to know quickly the link between event and line

TIGF collect data by LINE (ouvrage lineaire) (pipeline between 2 valves station) and
doesn’t used the SERIES table
=> 1 ROUTE = 1 SERIE
When a modification appears on a pipeline, TIGF delete the former pipeline and
regenerate the new one (due to the quantity of link between data)
A table allows to manage the pipeline creation, delete and re generation.

Inspection Planning with PIMS

A decision support tool to plan inspection and surveys

PIMS is named OGIC
Based on


A Threat Model (Threat Tree) and a methodology – TAME (BV + ATP)

A Structured database - PODS
Supported by Continuous improvement cycles common to other management
systems

Seeking to


Protect the assets

Identify and prioritize pipelines by threat level

Capitalize knowledge

Plan integrity actions (inspection / surveys / mitigations)

Optimize both capital and operating expenditures

To conclude
31
To conclude
VIGIE (GIS) and OGIC (PIMS) projects :
structure and share the information,
make TIGF regulatory compliant,
highlight true threats incurred by the pipelines,
outlay an inspection program based on true threats,
optimize actions means and resources
Nevertheless,
Survey (foot, car, plane ..) is, and remains the main guaranty of
the underground networks safety, for civil work carried out by
third parties that will never be completely controlled.
