Project synopsis for East West Gas Pipeline and Effective GIS Implementation
- 1. Proposed Project Synopsis On East West Gas Pipeline (EWGPl) by Reliance Gas Transport and Infrastructure Co.Ltd (RGTIL) and GIS implementation For Partial Fulfilment of Project Management - 2 Course by Soumik Chakraborty M.Tech GIS (MT19GGS260) NIIT University Neemrana, Rajasthan
- 2. INTRODUCTION The idea of this project revolves around the objective to fit Project Management Principles and methodologies to one of the most celebrated glorified project from Indian context which is the establishment of 1350 km length of truncated pipeline covering the Eastern and Western Ghats of Indian Peninsula. This huge gas pipeline once constructed will be the largest gas pipeline responsible for transportation of cheap fuel on important states of Andhra Pradesh, Telangana, Karnataka, Maharashtra and Gujarat. This Project has a huge significance other than playing its function as a transportation medium. Since it is a multi-faceted project. One objective it is to connect the Source and sink together as in to connect KG-D6 block of Krishna Godavari gas unit and make it reach to gas distribution and refineries of Gujarat. Another important facet is co-operating connectivity among multi-level Gas distribution organizations in the country such as GAIL, Andhra Pradesh Gas Power Corporation Ltd. Study focuses its idea around GIS application in the GAS transport Industry and how overall optimization will be achieved. Effective implementation of GIS will lead to reduction in overall Gas Transportation prices and stop accidental gas leakages. This will follow Data indexing of GIS maps, field operation, pipeline mapping and monitoring. This study will focus on the following major headlines:- 1. Introduction to the Project 2.

ArcGIS web enterprise software database connection providing linear pipeline referencing module with feature to have proper routing and planning of gas pipelines before proceeding with layout. The module provides with enhanced real time problem solving of pressure and three dimensional simulations. Assessment of Pipeline Geodatabase and Transmission line with feeder line separation. Geospatial provides location, mapping and management solutions with proprietary software and emerging technologies involve Geodatabase creation to include several domain of Upstream, Midstream and Downstreaming activities. Environment Protection using GIS surveys and layout of pipeline plan. Determination of the most cost effective and environmentally pleasing route for pipeline placement is one of the most controversial spatial problems encountered in the pipeline manufacturing and engineering industry. The most conventional means of routing pipelines consists of using a hand delineation method, which requires utilization of a manual overlay incorporating (x,y,z) topographic layers.

- 4. Expectations from the Study: It is expected that the study will provide clear understanding on how GIS can be applied to the field of Natural Gas pipeline Planning and Layout. Geo-referenced pipeline map of the East-West Pipeline Project is expected. Added to slope, elevation and Forest or wetland inventory mapped within the route. This provides with solid indication for the rerouted pipeline map which will be created keeping in consideration of the following factors of slope, elevation known as Primary factors and Environmental Polygons as Secondary factors for the pipeline setup. Added to the rerouted pipeline map, point layer geotagged facilities in the way of pipeline will also be mapped for serving as pumping stations and Gas distribution facilities. Within this point shapefile layer will serve as a clear separation among the three divisions of the oil and gas industry which is Upstream, Mid-stream and Down-stream. The pipeline industry faces a tremendous amount of scrutiny by environmental, government and other international agencies. Finally this study will give a brief understanding about the benefits of using GIS technology that of from traditional means. Important GIS Variables in the Pipeline Planning Process: • Shortest distance from source to market • Least grading • Cost associated with right of way • Slope of terrain • Number of streams, roads and rail road crossings • Wetlands crossing • Existing law and regulation • Proximity to population centers Strategic Purpose of the Study: The GIS format provides managers with a platform by which they can more easily evaluate pipeline assets. The ability to visualize pipeline features has proven to be a powerful tool for decision-makers saving valuable time and resources. Strategic purpose will also include logical GIS Linkages with the conventional format of Pipeline planning and management. Linkages exist in the form of elevation information collection in DEM format, Point shape file representing locational attribute of the Gas pipeline transmission facilities and also wetland or forest representation as overlaid polygons. The Q.A. or Quality Assurance range should be same as Cadastral Land Survey proportions. The more accurate and precise the data, the higher cost to obtain and store

For example, a 1-meter-resolution aerial photograph will cost more to collect (increased equipment resolution) and cost more to store (greater pixel volume) than a 30-meter-resolution aerial photograph.
