18 Conclusion Emission View - CO2 : about 25% reduced - NOx : about 80% reduced - SOx : about 97% reduced Commercial View - CAPEX : about 21% increased - Revenue : about 3% decreased - Fuel Cost : about 17% saved - RFR will be 2% higher than Conventional at same fuel prices Oil & Gas. Technical View - Engine Efficiency: 2% better - Total Energy Efficiency : 18% better - Special Gas Supply System required Conclusion For early adopting of Gas Fuelled Ship, it is needed that - Gap of fuel prices to be of over 10% - Initial Cost of GFS should be reduced - Loss of cargo space should be minimized - Potential risk should be eliminated 17/17
