Technical Audit of Oil & Gas
Pipelines PNIS Project
Contract : 1,4 M €
Consortium : Technipipe/AETS

Technical Audit Pipelines @ PNIS
Maintain and improve the long-term integrity of the
Central Asian Oil & Gas pipelines export to EU,
Overcome the gap of working environment between NIS
and Western oil & gas pipeline companies.
Use the establishment of a Pipeline Network Information
System as a basis for transfer of technology and
procedures to the gas transmission companies of
Central Asia.

Overall objectives
The industrial tool, the pipeline network should
no longer be seen as a black box and should
become totally transparent (glass box). At any
moment, the actual state of the pipeline system
and its evolution in time can be displayed.
The best way to get people to really care for the
cathodic protection is to show them concretely
the consequences of an ill maintained system.

SWOT of The Beneficiaries
Strengths
-Large experience in pipelines & Strong organization
-Good education background & Common working language (Russian)
Weaknesses (issues)
-Poor overall status of pipeline & no separate regulation organization
-Lack of exposure to the new technologies and Western standards
Threats (risks)
-Competition between the Beneficiaries for leadership
-Gaps of competence, procedures and technology will have to be filled
Opportunities and Assumptions
-The Steering Committee to reinforce the regional approach.
-The ground for a team of regional expert will be explored

Various phases of the Project :
-Inception
-4 Steering Committees (France, UZ, KZ)
-4 Dissemination seminars (UZ, KZ, KY,TU)
First 4 months : « Inception trips » :
..Analysis of environment, identification and contact of partners/ beneficiaries,
clarification of project objectives and strategy,
..Approval from Beneficiaries of planned activities, specification of PNIS…

Khiva Training Center
Intensive usage of Khiva Training Center
(Gas transportation Training Center
assigned to the project by Uztransgaz).
Training Plan made up of 8 Modules
designed after Competence/knowledge
assessment
Modules 1 & 2 : engineering, design,
construction and maintenance of
pipelines (Khiva, Almaty & Moscow)
Modules 3 & 3bis : Inspection (using tools
sourced from European suppliers)

Khiva Training Center
Module 4 : On site Above ground
Inspections (in Bishkek area)
Module 5 : On line Pigging (in Samarkand
with Rosen) of 40’’ x 156 km.
Modules 6 & 7 : PNIS implementation
operation & maintenance (theory only)
Module 8 : Train the trainers (for the
Beneficiaries to be able to train in their
own countries)

Conclusion
Priorities as per the 4 dissemination seminars :
1) Build/refurbish Cathodic Protection on full pipeline network.
2) Implement a large training program on Cathodic Protection
3) Collect the Cathodic Protection status by transmission network
4) Walk Survey weekly (Cathodic Protection efficiency, coating damage)
5) Prioritize above ground inspection (DCVG) where the Cathodic Protection
has failed or if the Cathodic Protection data are wrong
6) Dig out the pipeline where coating defects are suspected and carry out US
measurements, eventually repair

Priorities as per the 4 dissemination seminars :
7) Carry out intelligent pigging in the High Risk Areas
8) Develop an Integrity Management System/RBI (Risk Basis Inspection)
9) Develop repairs by clock spring method
10) Collect the Cathodic Protection Data in real time
11) Implement a PNIS
12) Implement a SCADA system (for new or revamped pipelines)

PNIS is a “Pipeline oriented Geographical Information System”
applied as a “Pipeline Integrity Management System”
It provides a tool to store and display the pipeline system (with pipe
characteristics and inspection data) in its geographical environment
It provides the computational analysis to determine segment length &
segment proximity to geographical land marks
It allows queries & reporting
It helps the user to classify the pipeline segments by pipe
characteristics (diameter, pressure, coating, etc.) by pipe status
(inspection data) or by geographical land marks

PNIS optimizes maintenance through Risk Based Inspection
RBI uses PNIS to :
Segment the pipeline according to risk factors
Identify risk contributors and deduce corresponding risk reducers
Rank / Assign weights to the risk contributors
Compute a risk factor per pipeline segment
And then to focus inspection on segments that most need it
