Technical Audit of Oil & Gas Pipelines PNIS Project

Contract : 1,4 M € Consortium : Technipipe/AETS

www.technipipe.com from July 2005 to December 2006

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.


Technical Audit Pipelines @ PNISSWOT 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)



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

Conclusion



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
