NIGC/GAIL Joint Venture decided to investigate the feasibility of building a natural gas transmission pipeline from South of Iran to India. The project comprises of two phases:

Phase 1 - The study of technical feasibility and viability of the offshore section of the pipeline including the offshore route survey covering collection of sufficient information for practical installation and operation of the submarine pipeline in the difficult areas.

Phase 2 - The study of the following onshore areas:

• Gas receiving facilities from the offshore field of the Persian Gulf. 
• Gas treating facilities including gas sweetening, sulphur recovery, NGL extraction and NGL fractionation. 
• Harbor and jetties for sulphur export.
• Infrastructure including residential facilities. 
• Onshore pipeline within Iran. 
• Transport studies for selecting optimum scheme for pipeline and compressor stations configuration. 
• Gas receiving station in India.
