specific exhaust gas pollution and GHG emissions.

4.3.4 CO 2 Index Data Analysis

The CO 2 index data analysis focuses on optimal fuel consumption. It is an entry
level analysis, which identifies the main factors of voyages with unexpectedly high
or low fuel consumption. The analysis is split into the individual vessels and a
comparison of the fleet's fuel consumption [ 61 ].
Ideally, the CO 2 index data of sister vessels are used; see Fig. 4.13 .
The result of the CO 2 index data analysis can be applied as input for the
Operational Fuel Consumption Analysis, together with data from each ship. The
experience of key crew members and the fleet management is integrated into the
interactive analysis of actual fuel consumption and ranking of improvement
measures.

4.4 Summary and Recommendations: Fuel System and Fuel
Measurement

The global tendencies of the market for fuel products are very similar and are
showing continuous growth in the price structure.
Fuel consumption can be measured in the fuel tank and in the fuel lines of the
vehicles, airplanes, and ships. Dynamic fuel sensors continuously analyze the fuel
flow from the tank to the engine and back from the engine to the tank.
