If a pick-up line 28 is not embodied, the vessel is typically navigated to a position where the vessel connector 7 is within reach from the vessel 14 and a pick-up line can be applied to the vessel connector 7. In the following, typical involved steps after having positioned the vessel are disclosed.
  • a deckhand uses a boat hook to pick the pick-up line 28 and brings the pick-up line 28 onboard the vessel 14 (see fig. 4F ).
  • the pick-up line 28 is arranged in a winch 17 which winches, by reeling in the pick-up line 28, the vessel connector 7 on-board the vessel 14 and to the gripping device 13 as illustrated in fig. 4H .
  • the gripping device shown in fig. 4 is illustrated in greater details in fig. 3A , B.
  • the gripping device engages (as illustrated in fig. 3B ) to grip the vessel connector 7.
  • the mooring tension is now carried by the gripping device 13 and the tension in the pick-up line 28 can be released, if desired, as illustrated in fig. 4J .
  • the electric conductive cable 4 can now safely be connected to a distribution board 36 of the vessel.
  • a distribution board 36 is typically configured to distribute electrical power to one or more electrical power consuming devices and/or power storage devices on-board the vessel.
  • the connection is typically carried out by a cable 38 which may be guided from the distribution board 36 by a cable guide 39 to the moored vessel connector 7.
  • the switch is turned on.
  • Fig. 5 illustrates some of the steps disclosed in connection with fig. 4 seen in a different perspective.
  • Figs. 5A-5C illustrates that the deckhand pulls the pick-up line 28 onboard the vessel.
  • Fig. 5C illustrates that the mooring connection 2 is about to be pulled on-board the vessel.
  • Fig. 5D illustrates the vessel being moored and illustrates that the mooring line 3 is tight whereas the electrical conductive cable 4 is hanging loose, that is the mooring forces are taken up by the mooring line 3.
