The second Rolandseck of the German Steamship Company "Hansa" (DDG "Hansa"), put into service in 1912, was their first motor ship and the first German seagoing ship with a motor drive on a screw.
The Rolandseck remained in the port of Lisbon when the war began in 1914 . Like all German ships in Portugal, she was confiscated on February 24, 1916. She was put back into service as Mira , but on November 26, 1916 the ship sank after a collision off the west coast of Spain.
History of the ship
Named after the tourist resort Rolandseck near Remagen , the second Rolandseck of the DDG "Hansa" took up the name of the shipping company's smallest ocean-going vessel.
The shipping company received the first Rolandseck of only 736 GRT / 850 tdw in 1882 from the JW Klawitter shipyard in Danzig for the Baltic Sea. The little steamer had been in service with the shipping company from October 1882 to March 1904 and was then sold to the Bremen shipping company Wischhusen & Kimme , which continued to use it as Ravensberg .
The new building was intended for the Spain / Portugal service, for which the shipping company had the two small steamers of the Soneck class (1902, 1121 BRT / 1643 tdw) available when the order was placed .
The new building commissioned from the Joh. C. Tecklenborg shipyard under construction number 250 corresponded in its external appearance to the small coastal steamers of the time. The new Rolandseck was 88.5 m long and 12.24 m wide. It had two masts with the loading gear from a 20 t boom on the front mast and eight 5 t booms on the masts and two cargo posts next to the chimney. This was located behind the bridge structure, separated by the smaller third loading hatch on the front edge of the boat deck structure, which also contained the cabins for any passengers. Despite the large chimney, there was no steam engine with its boilers, but a diesel engine .
The DDG "Hansa" decided to build a motor ship in order to compare its operating results with those of their steamers. The annual report of March 29, 1912 stated: “One of these new buildings will be equipped with a diesel engine. This ship has a size of 2500 tons deadweight and the engine is supposed to develop 1500 HP. The ship is to be put on the Portugal voyage, and based on the experience we have gained, we will be able to decide later whether the diesel engine will be an option as a replacement for our larger steamers. ”The new ship was added on August 3, 1912 Joh. C. Tecklenborg from the stack. Rudolf Diesel was personally present during the test drive on November 16, 1912.
The freighter Rolandseck of the DDG "Hansa" was put into service on November 16, 1912 as the second sea motor ship built in Germany, after the Monte Penedo of the Hamburg-Süd . She was the first larger seagoing ship with a diesel engine built in Germany. The engine was also built by the Tecklenborg shipyard according to plans by Rudolf Diesel under the supervision of the Belgian subsidiary Diesels. It was a six-cylinder, single-acting two-stroke engine with 1500 hp at 120 revolutions per minute. The cylinders with a diameter of 510 mm and a stroke of 920 mm were arranged in three groups of two cylinders each.
Rolandseck made her first trip to England before she - as planned - joined the shipping company's Portugal / Spain service. Their first trips and experiences were reflected in the report by the construction engineer C. Kielhorn in the "Polytechnisches Journal". The most serious accident in the Rolandseck's first year of operation was a fire in the engine room on September 18, 1912 on the Amerika-Kai in Cuxhaven . In 1913 the shipping company reported:
“Our motor ship has generally proven itself well; In view of the enormously increased prices for crude oil, however, the operation is not as profitable as we were able to assume at the time we ordered the 'Rolandseck'. For this reason, we have chosen a three-cylinder steam engine as the engine for a sister ship. ”
So the Rolandseck remained a single ship. The (second) Lahneck with steam engine drive, completed by Seebeck in 1914, was very similar.
Until the World War, only six diesel-powered seagoing ships were built in Germany; a ship was bought from abroad for this purpose.
Fate of war
At the beginning of the First World War, the Rolandseck sought refuge in neutral Lisbon on August 1, 1914 . She stayed there for almost two years. On February 23, 1916, like all German ships in Portugal and its overseas possessions, she was confiscated by the Portuguese government under British pressure. At the start of the war, 72 German and two Austro-Hungarian ships were in Portuguese ports, 35 of them in Lisbon alone. Portugal founded the state company "Transportes Maritimos do Estado" to bring these ships back into circulation. The fact that this would take place on the Entente side after the war situation led to the German Reich declaring war on Portugal.
In the Portuguese service, the ship, renamed Mira , sank on November 26, 1916 after a collision off the Spanish coast.
