Abstract: An energy transmission device for a watercraft includes a tower arranged on land, a telescoping boom connected to the tower for pivoting about a horizontal axis and about a vertical axis, said boom including a free end, and a first plug connected to the free end of the boom and designed to electrically contact for transmission of electrical energy a second upwardly oriented plug on the watercraft via a vertical plugging motion from above by pivoting the boom relative to the tower.

Abstract: An apparatus for electrically connecting a polyphase vessel distribution system of a vessel to a polyphase land supply system having a supply system connection disposed on land to be connected to a vessel system connection of the vessel distribution system at least in sections by at least one cable connection, enables a fast and secure connection of the land supply system to the vessel distribution system. During normal operation, vessel movements can be reliably compensated by at least one articulated arm used as a support for one or more cable connections. The articulated arm has arm segments interconnected by at least one articulated connection. A joint drive is associated with each articulated connection for mutually pivoting the arm segments interconnected by the articulated connection, which is associated with the joint drive.

Abstract: A power supply device for a ship stationed on a mooring of a harbor includes a land-based, horizontally displaceable carriage, on which a power supply line with a plug is disposed for supplying the ship with electrical energy. The power supply line can be electrically connected to a land-based power supply network. A plug-side section of the power supply line is disposed in a vertically displaceable manner on the carriage.
