1. A system comprising a submarine vessel and a submarine docking port for the submarine vessel, where the docking port is arranged for transfer of electrical energy to the submarine vessel when the submarine vessel is docked, and the submarine vessel is provided with a submarine navigation system, wherein the docking port is provided with at least one primary coil arranged for emitting a magnetic field, and the submarine vessel is provided with a secondary coil, the submarine vessel is provided with means for measuring a strength of the magnetic field received by the secondary coil, and the submarine vessel is provided with a positioning electronics that guides the submarine vessel in a horizontal plane (X-Y plane) to maximize the measured local magnetic field, and the positioning electronics guides the submarine vessel in the vertical direction (Z-direction) when the measured magnetic field is at a local maximum and the magnetic field increases when the submarine vessel descends towards the primary coil.
