000007698 520__ $$aThe requirement to maintain and uplift fuel in naval vessels is a necessary operating constraint and, with<br>
projections forecasting that fuel oil prices will continue to rise, uplifts need to be scheduled to deconflict with<br>
military tasking whilst being financially efficient. This paper presents mission fuel management as an optimisation<br>
problem, where analytical techniques are used to explore the impact of intelligent uplifts, intelligent leg<br>
speeds and the impact of minimum fuel holding restrictions and hull bio-fouling. Using a representative transit,<br>
we demonstrate that relative fuel price differences between ports may be exploited to achieve mission fuel<br>
cost savings of 15% to 25%, without impacting mission dates. For time constrained transits, being those with leg<br>
speeds limited by the minimum fuel holding restriction, a saving of 4% to 5% is achievable by varying leg speeds.<br>
Finally, we conclude that challenging minimum fuel holding requirements can yield up to 5% saving, whilst hull<br>
bio-fouling has an almost negligible effect in our model (due to the short time at sea). Extrapolation indicates<br>
that whilst fuel consumption will invariably increase for a given speed, it does not affect the fuel uplift decision<br>
making.
