The side paddle steamer Prinz Albert , launched in 1838, was one of the first steamships built in Germany on the Upper Elbe . The ship was named after Albert von Sachsen-Coburg and Gotha .
Prince Albert (1836/1838)
In 1836 the Elbe Steamship Company gave Johann Andreas Schubert , professor of mathematics and mechanics at the Dresden Technical College , the order to build two steamers. Under his direction and with the cooperation of the engineers Tauberth and Möhring, the steamers Queen Maria and Prince Albert were built. He got ideas from a three-month study visit financed by the Elbdampfschiffahrts-Gesellschaft in France, where he studied steam navigation on the Seine .
The ships were built on the Dresden Vogelwiese between Ziegelstrasse and Rietschelstrasse on the banks of the Johannstadt Elbe. Construction began in September 1836. In order to be able to continue construction in winter, a shipbuilding hall was built on the site. After the ship's hulls were completed in April 1837, they were towed to the Übigau mechanical engineering company . The steam engines were supplied by the Berlin factory owner Franz Anton Egells , who set up his machine factory in front of the Oranienburger Tor in Chausseestrasse in 1825 . The boiler and machine were installed in the Dresden suburb of Übigau . In 1838 which took place launching of Prince Albert . The ship had a length of 32.85 meters, a width of 3.68 meters and a width of 7.84 meters across the wheel arches. It offered space for 450 passengers with a draft of 0.75 meters.
The period from 1838 to 1844
The first test drive took place on May 20, 1838. However, the result was unsatisfactory. Further test drives took place on July 8th and August 2nd, 1838. It was found that the steam boiler, the tubular boiler installed by Übigau, did not provide enough steam for the steam engine. But it was also assumed that the steam engine was actually producing 150 hp instead of the specified 120 hp and that the steam boiler was therefore too small. In the spring the ship got a new boiler from the company MH Göbel from Zauckerode . At four tons, this cylinder boiler was half as heavy as the old boiler. From May 1839 the trips to Pillnitz and Schandau were started. In 1840 the ship was overhauled at the shipyard in Krippen . To replace the steam engine, which was unsuitable for the shipping conditions, the ship sailed to Hamburg on July 3, 1840 . Here it was equipped with a new machine and a new suitcase boiler developed by Schubert. On October 4th, 1840, it was back in Dresden. During the test run on October 18, 1840, the ship reached Tetschen after 7 hours and 23 minutes . This corresponds to a speed of 3.9 knots . Tetschen was even achieved without a pre-tensioning aid.
In the autumn of 1844 the ship was scrapped in the Buckau machine works in Magdeburg . The successor ship Prince Albert II received the steam engine .
The steam engine
Schubert wanted to install a high-pressure steam engine from the Dresden Actien-Maschinenbau-Verein's own plant in Übigau , but failed because of the regulations of the government offices. Then a two-cylinder, low-pressure side-balancing steam engine from Franz Anton J. Egells Berlin was installed. The power of the machine was 120 hp. Due to the three times higher weight of this machine, the draft of the ship was 0.74 m instead of 0.43 m. This led to basic hits on the first trips. In 1840, a lighter oscillating low-pressure two-cylinder twin steam engine from the English mechanical engineering company John Penn and Sons was installed in Hamburg . The machine had an output of 96 hp. The old steam engine company Egells came from 1,844 in the manhole in Bockwa in Zwickau coal district to drive the dewatering machine used.
