GIS Mapping of Pan India Pipeline Network GAIL has taken an initiative to map its entire pipeline network through GIS MAPPING PROJECT. The coverage of the Project is:
correlated with MSL for plotting pipeline profile).
(24 months)
Integration of all pipeline Integrity assessment data in a common database and its analysis CPIMS is a GIS enabled computer application to maintain, align and analyses various pipeline integrity survey with ability to facilitate risk assessment. It is suite of different modules such as Feature Assessment module, Cathodic protection module, Risk Assessment module etc. GIS Based - Pipeline Integrity Management System (PIMS)
MOBILE BASED APPLICATION GAIL has developed a mobile based application software. This facilitates accessibility of ready data based for pipeline parameters covering more than 40 attributes from any location through GSM mobile having GPRS. It provide live Data for pipelines and compressor, Generation of Work Permit as well as enable the officer at site the Updation of Maintenance Data in SAP Platform
Information Data Bank on major maintenance activities Enabling Maintenance Information through Mobile
NATIONAL GAS MANAGEMENT CENTRE & RGMC National Gas Management Centre (NGMC), state of art control system, monitors all critical parameters/operations of the pipeline through an on-line SCADA system It monitors Real time data of all Pipeline Parameters, Supply and Delivery Conditions at all Sources and Major Customer terminals through SCADA. NGMC Coordinates with Regional Gas Management Centers to handle any upset in the process. It acts as a Nodal center for crisis management of GAIL installations.

MTM is a non-intrusive pipeline inspection technology based on Magnetic Tomography Method. MTM evaluates the relative change in mechanical stress through the pipeline magnetic field strength measurement. It helps to locate defects in metal & weld joints, assess the state of corrosion & monitor the development of corrosion. Magnetic Tomography Method (MTM) Contactless Magnetometric Diagnostics method (CMDM) Contactless Magnetometric Diagnostics method is another tool that is used for ensuring the Integrity of the Non-Piggable Pipeline. This method comprises of acoustic emission, ultrasonic thickness gauging, vibration diagnosis to enable the execution of check of the facility’s technical state when in service on the basis of different NDT methods.
For monitoring of ROU, GAIL has started Foot patrolling along its pipeline with GPS devices. GAIL is in advanced stage of implementing use of Unmanned Aerial Vehicle / Drone in surveillance of pipelines at harsh locations. Also, latest pipeline monitoring technology, namely “High resolution low orbit satellite imaging”, is being implemented in GAIL. A pilot project on remote surveillance in DVPL pipeline by R&D department of GAIL in collaboration with National Remote Sensing Centre (NRSC).

GAIL has implemented Centralized Application Software (APPS) System for modelling its entire Natural Gas and LPG Pipeline Network. GAIL has conducted a study regarding the feasibility of usage
in Natural Gas cross-country pipelines which are passing through city or in the vicinity of the city locations. Odorization is being done in one of the pipeline on pilot basis. GAIL has also taken an initiative to install RMLD-Remote Methane Leak Detector. It quickly and efficiently detects leaks up to one hundred feet away allowing remote detection of hard-to-reach areas and difficult terrains

GAIL has engaged Subject Matter Experts to review existing Maintenance Practices and thus comparing them with world’s best practices and thereby recommending modification for improvisation. The hiring of expert advice from the reputed consultant/agency re-assure the effectiveness of our existing practices/policies. It also ensure the safety and health of persons and the environment by the reduction of hazards and risks to a level as low as reasonably practical in normal operating conditions or in an emergency. Following subjects matter have been hired by GAIL:
: Mr. V R Krishnan
: Mr. Patrick J Teevens
: Mr. Sidney A Taylor
GAIL has taken the initiative to give training to GAIL pipeline officers through NACE and ASME to create the required Cadre Based Team. The NACE agency has been hired to give training on:
GAIL, on regular basis, has organized Pipeline Operators Meet for discussions on various pipeline operation & maintenance issues where pipeline operators like M/s IOCL, M/s BPCL, M/s OIL, M/s RGTIL, M/s Cairn Energy and M/s HPCL participated. GAIL executives are nominated to participate in various National and International Seminars like ICEPIM, NCCI etc.
GAIL in collaboration with NIGIS has conducted Technical Seminars on Internal Corrosion of pipelines JANG SE JANG-I & JANG SE JANG-II (Battle With corrosion-II .The representative from industries- GAIL, RIL, RGTIL, IOCL, BPCL, HPCL, VOLT, EIL, MECON,TRACTABLE, CEIL IGL,MGL, OISD, experts from M/s NACE international, CIMG(Central Integrity management group), RIMG (Regional Integrity management group) and personnel of GAIL from sites has participated.
