As the exclusive natural gas distribution company in Istanbul, İGDAŞ now ranks 3rd in the natural gas sector in Europe.

Objectives:

Established in 1986, İGDAŞ's mission is to provide the public with clean burning natural gas and to establish and operate all infrastructural and related facilities for the utilization and purchase of natural gas.

Operations:

- To ensure maximum safety, the steel pipelines of the network are constructed only after detailed ground examination has determined the area is in a secure, low-risk earthquake zone. In the event of gas leakage or a pressure fall in these pipes, the Main Feeding Station will sense the pressure fall automatically and cut off gas feed.

-Regional regulators feed gas into polyethylene pipes, which carry the gas to the service boxes. These regulators contain security valves which can sense any gas pressure fall in the network and cut off gas flow immediately.

-Polyethylene pipes carry the gas to the service boxes on streets and in front of buildings. These pipes are
grossly elastic (600%) preventing damage or breakage from earthquakes or other impact. The service boxes also contain security valves to cut off gas flow in the event of an emergency.

-For increased safety, İGDAŞ has implemented an emergency hotline customers can call to report problems. With offices and intervention teams located on both sides of the Bosphorus, İGDAŞ engineers can be dispatched rapidly in the case of an emergency.

Pressure Regulating Metering Station

- İGDAŞ uses the İGABIS Infrastructural Data Processing System. This GIS-based system includes a detailed map of Istanbul along with a database containing locations, streets, buildings and all intersecting points relating to the natural gas network and the position of natural gas lines. İGDAŞ uses the information in cooperation with other organizations to coordinate infrastructure projects while maintaining the integrity of the gas network. İGABİS can also be used to show the consequences of gas shut down on any valve - i.e. which buildings and areas will be affected - before any decisions are made.

RMS-A Pressure - A Type

o İGDAŞ uses the SCADA Remote Monitoring, Data Acquisition and Control System to monitor and control the natural gas distribution network 24 hours a day. The system checks 10 parameters simultaneously like gas pressure, volume, flow, leakage, regulator valves and filter clogging.
