  1. CRITERIA FOR SITE SELECTION FOR LNG REGASIFICATION TERMINALS 7th Petro India 2008 Gas in India – Issues, Opportunities and Challenges By: Sham Sunder, Advisor (Technical) ESSAR

  2. Presentation Frame • Gas Scenario in India • LNG Chain • LNG Regasification • Port Selection • Conclusion

  3. GROWTH OF GAS DEMAND IN INDIA • Large supply deficit • Industry using liquid fuels • LNG import to reduce growing gap • LNG a viable fuel in Indian market Gas Demand (MMSCMD) Source: Report of Working Group (XI Plan) of Government of India

  4. PROJECTED DEMAND - SUPPLY GAP FOR NATURAL GAS Source: Report of Working Group (XI Plan) of Government of India

  5. WHAT IS LNG • LNG Is Natural Gas Liquefied at –160 oC. • NG is liquefied to make it suitable for transportation in LNG ships through sea routes where transportation of NG by pipeline route is not feasible / economical. • During the Liquefaction process NG is purified to very high level. • LNG is therefore environmentally friendly and efficient fuel. • LNG is subsequently regasified at receiving terminal for use by the End users.

  6. Liquefaction Loading Transfer Storage Gas Field Transport (Ballasted) Transportation (Loaded) Vaporized LNG to Gas Consumers Pumping Unloading Transfer Regasification Storage LNG CHAIN

  7. LNG TERMINAL DAHEJ AIR HEATER Metering STV FUEL GAS SCV GW PUMP STV HW / GW EXCHANGER WATER PUMP FOR BACKUP BLOWER BOG COMP. RECONDENSOR UNLOADING/ VAPOR RETURN ARMS GTG LP PUMP HP PUMP SHIP LNG TANK

  8. CRITERION FOR PORT SELECTION • Sufficient land area near the shore (40 – 50 hectare) • Availability of Infrastructure • Mild natural Conditions • Winds • Tides • Currents • Waves • Preferred Sheltered Area • No human population nearby • Required Draft Close to shore

  9. PORT REQUIREMENT • Depth 14.5 m • Approach Channel width 300 m • Turning Circle 600 m to 700 m • Preferred Natural Draft • Trestle length to be minimum (Maximum 3 Km)

  10. MARINE OPERATING LIMITS Note: ** indicatesShips and Mooring Systems have to be designed for maximum currents

  11. CONCLUSIONS • Natural Gas demand is growing fast • Natural Gas as a feed stock and fuel is very safe, efficient and economical • Emission of green house gases from RLNG is least • LNG chain is highly capital intensive. Therefore, total chain has to be tied up before commencing construction • Thorough study for site selection is required in order to minimize the investment. • More LNG terminals are expected in the near future. ** LNG is the fuel of future **
