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