This paper concerns the estimation of optimal energy paths to dose power demands in autonomous underwater vehicles with the end to achieve maximal autonomy in the presence of a flow field. The trajectories searched for are parameterized and structured on a grid (usually employed in sampling missions on the sea bottom) with a relative orientation with respect to the current flow. The optimal solution is a set of cruise velocities along the path. A practical approach is developed in real time for accomplishing path corrections due to spurious in the flow. A theoretical background is developed and a simulation study is given with comparative optimal and suboptimal solutions.
