Presentation Frame

  • Gas Scenario in India

  • LNG Chain

  • LNG Regasification

  • Port Selection

  • Conclusion


Growth of gas demand in india

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


Projected demand supply gap for natural gas

PROJECTED DEMAND - SUPPLY GAP FOR NATURAL GAS

What is lng

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.

Criterion for port selection

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


Port requirement

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)


Marine operating limits

MARINE OPERATING LIMITS

Note: ** indicatesShips and Mooring Systems have to be designed for maximum currents


Conclusions

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 **
