The transport of trade and consumer goods is essential for the economy and for people themselves. The sea route is one of the most important trade routes in the world. The long distances across the world's oceans are covered by thousands of different ships every day. However, the current overseas ships transporting containers or other goods across the seas account for 3 percent of the world's CO2 emissions. Climate change is becoming more severe and visible every year. It is all the more important to reduce and minimize anthropogenic causes of climate change. This concept deals with finding an alternative for the current heavy oil burners. It combines the possibilities of converting wind energy into electrical and kinetic energy.

concept declaration.

In the design phase, a basic concept has been worked out that forms the basis for the design of this work. The power for the electric drive is supplied by an integrated redox flow accumulator. This also provides the power for the on-board systems, such as position lights, instruments or lighting. The accumulator is charged by a shore connection, which can be used during loading times due to the integration into the port's infrastructure. In addition, the ship has its own generators in the form of Darrieus rotors, which convert wind energy into electrical energy regardless of the ship's speed and store it in the ship's redox flow systems. In external charging stations, the ships can pause and recharge the integrated batteries.


The "Set Up" was assembled from prioritized components in order to build a reference of the concept that is as close to reality as possible. This scale is used as a reference for the design. Here, the Set Up's priority is directed towards the propulsion system and the size scaling of the vessel due to the containers to be transported.

Engines and technology. In the stern are the engines, as well as the associated technology for driving through the water. In the bow of the ship there are also thrusters, which are responsible for lateral maneuvering. For the adjustment of the sails are also installed electronic motors in combination with the generators.
Living and working space. On average, up to 22 people live and work on a container ship of this size. The living and working space amounts to approx. 30,000 m3.
Accumulator. The accumulator capacity is divided equally among the ship. Generally, there is the largest power storage in the middle. Ahead and aft are each used as free spaces in a modular fashion.
Generator. On the deck of the ship are generators that are responsible for generating electricity. They are connected to the wing sails.
Cargo. On a cargo area of 2x ~73 m x ~36 m up to 12,000 TEU containers can be stacked.
General dimensions. The length dimension of the raw ship is at least ~253 meters, the width is 40 meters. The height of the ship without cargo is 36 meters. The cargo overhangs ~7.5 meters above the ship's dimensions. This adds up to a total height of ~43.5 meters. The draft should be less than 15.2 meters. The total ship dimensions include Suezmax, Setouchmax, Q-Max, Panamax II, Malaccamax, Dunkirkmax, Chinamax, among others.
