The present invention provides for an adaptive tension compensator system for offshore charging of a vessel via an umbilical cable of a motor driven reeling drum provided at a power station. The compensator system comprises a motor hub member (102), mountable to a motor shaft (20) and configured to transmit rotary motion between a motor (18) and the reeling drum (16) along a first rotational axis (104); a reel hub member (106), mountable to the reeling drum, arranged coaxial with said motor hub member and configured to transmit rotary motion between the reeling drum and the motor, and a coupling mechanism (108), operably coupled between said reel hub member and said motor hub member, adapted to transmit rotary motion between said reel hub member and said motor hub member when the motor is in a first mode, and adapted to provide a biased rotational motion of said reel hub member about said first rotational axis between a first angular position (110) and a second angular position (112) relative to said motor hub member, when the motor is in a second mode.

A device (1) is configured to supply a consumer, the position of which initially cannot be exactly determined but later can be substantially stationarily fixed, with energy from a stationary supplier. The device includes a movable carriage or slide (2) connected to an arm (3). The arm (3) is movable between first and second positions (7, 8) and includes at least one plug part (4) for connection to a consumer's energy supply line (5). The plug part (4) is connected to the supplier with an energy supply line (6). A cover part (9), which is movable with the movement of the arm, is arranged on the arm (3). In the arm's first position (7), the cover part at least partially covers the plug part (4), and in the arm's second position (8), the cover part exposes the plug part (4) for connection to the consumer's energy supply line (5).

A device for connecting a ship to a land-side supply grid includes a rail system having a guide channel, a cover designed to cover the guide channel and formed by a plurality of successive articulated cover plates and a land-side coupling unit mounted on the rail system for travel and designed for receiving a cable-connected ship-side plug. The coupling unit includes a lifting device designed to open the cover by opening the cover plates in a position-dependent manner, and a shield to protect an area of the guide channel opened by the lifting device against falling objects. A cable carrier cable-connects the coupling unit to the land-side supply grid. The cable carrier is arranged lying flat on a side in the guide channel and pivotable about a vertical bending axis.

A mooring buoy for a vessel comprises a floating body arranged to project out of the water. At least one buoy anchoring line is connected between the floating body and sea floor. At least one vessel mooring line is connectable between the mooring buoy and the vessel. At least one moveable electric cable is connected to a power supply and the moveable electric cable has a free end connectable to a switchboard of the vessel when the vessel is tethered to the at least one vessel mooring line. The free end of the at least one moveable electric cable is moveable between a retracted position and a connected position and the tension of the at least one vessel mooring line is greater than the tension in the at least one moveable electric cable when the free end of the at least one moveable electric cable is in the connected position.

The invention relates to a device 1 for connecting a ship to a shore-based power supply network, wherein a shore-based coupling unit 2 for connection to a cable-bound ship-based plug connector is movable in a rail-guided manner and is connected via at least one power supply line 16, 17 to the shore-based power supply network, wherein the coupling unit 2 is arranged on a travelling mechanism 4 whose wheels 5, 6 are arranged side by side in two tracks 7, 8, wherein one track 7 is rail-bound with respect to a rail 9 which is arranged on the waterway side on a vertical side a quay wall 3, wherein the travelling mechanism 4 overlaps mooring apparatuses 11 projecting from a top side 10 of the quay wall 3, such that the second track 8 is arranged on a side of the mooring apparatuses 11 remote from the water.

This operation mode selection device selects an operation mode of a ship power system including one or a plurality of generators and batteries, the operation mode is determined through at least the number of generators in operation, the selection of a generator to be operated, a load sharing ratio of the generator and a battery, the selection of charging and discharging of the battery, and the device comprises a reinforcement learning unit which selects the operation mode; and performing reinforcement learning on a software agent.

A device for inductively transmitting electrical energy between a power supply unit arranged on the shore of a body of water or in the body of water and a watercraft includes a primary coil associated with the power supply unit, and a secondary coil which is connectable to the primary coil for inductively transmitting electrical energy, and which is arrangeable on the watercraft. A height-adjustment device connected to the primary coil is provided in order to hold the primary coil at a consistent vertical distance from a water surface in a vertical direction running in the direction of the buoyancy. A corresponding charging system and method includes: aligning the coils relative to one another; previously or simultaneously adjusting a vertical distance between the primary coil and water surface by with a height-adjustment device; inductively transmitting electrical energy between the coils.
