Figure 3.
The figure presents a graph with capacity factor on the horizontal axis from 0.28 to 1 and tons fuel per kilo tonne cargo on the vertical axis from 40 to 120. A curved decreasing line shows that fuel use per kilo tonne cargo declines as capacity factor increases. Two vertical markers highlight capacity factors of 0.28 and 0.50. A linear extrapolation is shown with a broken line, extending upward from the curve. Annotations show that the difference between 113000 and 88000 divided by 3218 times 1000 is 0.0074 kilogram per tonne kilometre and the difference between 104000 and 88000 divided by 3218 times 1000 is 0.0050 kilogram per tonne kilometre. Additional horizontal markers indicate upper and lower bounds of fuel use at 0.28 capacity factor and expected fuel use at approximately 0.50 capacity factor. A legend explains intercept location, linear extrapolation, upper bound, lower bound, and fuel use at 0.50 capacity factor.Superimposition of improved capacity utilisation on extract of Henningsen’s plot
