The study has assessed the feasibility of a new 56-inch line – IGAT-4 – to pump gas from the offshore South Pars field and the onshore Tabnak field. According to PLE’s study, IGAT-4 will have a length of about 700-800 kilometres and will be designed to transport 110 million cubic metres a day of gas. The new trunkline will increase the volume of gas flows to the north of the country.

It is understood that NIGC has asked the local Tehran Jenoubto carry out an additional study for IGAT-4.
