Abstract: A ship that is to be coupled electrically to a terminal a method, and a method and a device for connecting an electrical power line (1) between a ship (3) and a terminal (5). The device includes an unwinder (7) for unwinding a traction cable (13) from the ship (3) towards a connection end (15) of the electrical power line (1); a lashing device (9) for lashing the traction cable (13) to the connection end (15); and a traction device (11) for pulling the electrical power line towards the ship (3) so as to connect the connection end (15) with an electrical interface (17a) of the ship (3).
