A system (1) comprising a submarine vessel (2) and a submarine docking port (3) for the submarine vessel (2), where the docking port (3) is arranged for transfer of electrical energy to the submarine vessel (2) when the submarine vessel (2) is docked, and the submarine vessel (2) is provided with a submarine navigation system. The docking port (3) is provided with at least one primary coil (41) arranged for emitting a magnetic field (5), and the submarine vessel (2) is provided with a secondary coil (42), the submarine vessel (2) is provided with means for measuring a strength of the magnetic field (5) received by the secondary coil (42). The submarine vessel (2) is provided with a positioning electronics that guides the submarine vessel (2) in a horizontal plane (X-Y plane) to maximize the measured local magnetic field (5), and the positioning electronics guides the submarine vessel (2) in the vertical direction (Z-direction) when the measured magnetic field (5) is at a local maximum and the magnetic field (5) increases when the submarine vessel (2) descends towards the primary coil (41). A method for docking a submarine vessel (2) on a submarine docking port (3) is described as well.
