The climate-neutral seminar ship operated with HOPPECKE batteries has successfully completed its maiden voyage to Berlin. The ship was built by the Stralsund-based companies Formstaal and Ostseestaal on behalf of the Berlin-based seminar ship Fluxservice GmbH. It is mainly powered by solar energy, with a biofuel engine for remaining requirements. The propulsion batteries, as well as those for on-board power supply are from the energy storage specialist HOPPECKE, who has already equipped numerous other ships with batteries.


On August 10, the ship was officially handed over to the operator and investor Felix Eisenhardt. He immediately went on his maiden voyage. He has had many months of hard work behind him that have paid off: "I am glad and proud that everything has worked out so well and that the ship has also passed the extensive safety tests in the water without any problems. Now we enjoy driving. It's an indescribably great feeling to be on the way with the climate-neutral and modern seminar ship."


HOPPECKE provides propulsion and onboard power supply for the ship

The seminar ship is a multifunctional event space for the water. Up to 200 people can stay on the 35-metre-long and eight-metre-wide ship. On its lowerable roof there is a photovoltaic system with an output of 31kWp. A total of 129 HOPPECKE batteries with a total capacity of 250 kWh can store the energy. Even without sunshine, the ship can sail for up to seven hours. In addition, the batteries operate the on-board power supply and serve as emergency power supply.

The ship is not only dependent on the sun: On board there is a generator with 160 kW, which takes over the power supply in case of high energy demand or insufficient solar radiation. Instead of diesel, HVO (Hydrogenated Vegetable Oil) is used as a fuel: this is a fuel made from used vegetable oil and fat, which has been converted into hydrocarbons in a refinery by a catalytic reaction with hydrogen.
The generator will be used mainly in the low-energy winter season: The waste heat from the engine will then be used for underfloor heating. In the ventilation concept, Felix Eisenhardt and his team transferred technologies from low-energy buildings to the ship. Then the ship was fitted with multiple glazed windows and good thermal insulation. No one has to freeze on this ship, not even at freezing outside temperatures. In summer, an efficient air conditioning system ensures pleasant temperatures.


Also the 2.50 metre high inner room was very important for Felix Eisenhardt when he designed the seminar ship. You need freedom above your heads to feel comfortable on board. Mobile partition walls, state-of-the-art event technology, W-LAN, an innovative lighting concept and an attractive interior design round off the concept of the seminar ship. A special highlight are the two anchor piles integrated in the ship. These telescopic stilts can be lowered to a water depth of up to six metres to the ground. That allows the ship to stop on the water.

The seminar ship "Orca ten Broke" has its homebase in Berlin. It can navigate all inland waters of Germany and Europe. In Germany alone, the seminar ship reaches 18 of the 20 largest cities. For example, there are already requests for "road shows" in NRW, Hessen and Baden-Wuerttemberg.
