3. Background
Pipeline Operator’s goal – Incident free operation, invest substantial human and financial resources to protect the pipeline
Pipelines traverses through different regions
In pipeline failure emergency, multiple departments need to collaborate, sharing data and information about actions to be performed.
Emergency Resources are not on network and interaction among departments and emergency corps are limited.
Result in slower response in emergency

4. Major Pipeline Emergency Challenges
Multi Site Operations
Large Volume of high pressure gas transportation
Pipeline traverses different geographical area
Un authorized third party activities
Emergency Services (Fire/Police/Hospital etc.) not near vicinity

5. Geographical Information System for Emergency Response
Emergency relevant data have many attributes i.e. Incident Location, Pipeline details, Emergency facility location details, approach roads etc.
Geographical Information System plays a vital role to access different attribute information with one platform.
GIS support decision making by facilitating the integration, storage, querying, analysis and reporting centralised information.
GIS have a new type of mapping systems which is highly responsive mapping framework support API.
With the use of GIS functionalities over the Web enable different department can act on single centralized platform.

6. Proposed Emergency Event Support System
EESS is the real-time integrated web GIS Application, supporting Emergency Response Plan of Pipeline Gas Transportation.
enable user to trace the incident location on map along with Village Name and Taluka Name
give best suitable Facility Location around 5 – 10 km buffer area of Incident Location
provide the best shortest route along with direction and distance from facility to incident location.

9. Development of EESS System Application Prototype Design
Develop System such that it easily retrieve data from database and display as user need
Map API, Server & Dynamic Web Page Language
Map APIs are used for displaying GIS layers and its directions services are utilized for generating shortest route
dynamic web language pages provides dynamic content to the web
Application Design
With the help of database and API desired output can be generated.
Main feature of the application is to use direction services which communicate with API for receiving direction request and returned the computed request.

10. EESS System Flow Receive Pipeline Chainage
Match chainage no. with the bakpl_pipe table
Get Incident Location on Map
Is the chainageno. match with table
Yes
Get Emergency Facility Location around the Incident Location
Get Shortest Route between Incident Location and Emergency Facility Location
Select Emergency Facility Location for Emergency Access
End
Chainage no. doesn’t match or error
Require Shortest Path ? No

16. Conclusion & Future Work
The web GIS EESS system is proved useful for easily finding Incident location along with emergency information at single platform.
Easing interoperability among emergency facility locations
Easily provide user selected approach route for easy access of incident location.
In Future, options for integration between SCADA and Web GIS EESS shall be made to avoid manual entries.
To develop customised mobile app and provide to emergency facility provide, it will enable to get incident information on real time.
