Rotterdamsche Droogdok Maatschappij
The Rotterdamsche Droogdok Maatschappij (RDM) was the largest pre-World War II shipbuilding and repair company in Rotterdam in the Netherlands, existing from 1902 to 1996. It built 355 mostly major seagoing vessels, 18 of which were submarines.:nl:Rotterdamsche Droogdok Maatschappij, RDM on the Dutch Wikipedia During its existence, the wharf operated 12 floating docks and in its heyday employed 7,000 people at one time. Establishment of the company The Rotterdamsche Droogdok Maatschappij was a successor of the company De Maas, founded in Delfshaven in 1856 by Duncan Christie. Shipbuilder De Maas was located in an area that is now the Saint Job's harbor (Sint Jobshaven) of Rotterdam. This company would have to move in 1905 because the lease on the land would end that year. On 14 February 1899 it therefore bought 4.5 hectares of land in Heijplaat, south of the Meuse for 44,000 guilders.

Rotterdam
Rotterdam ( , , , lit. ''The Dam on the River Rotte'') is the second largest city and municipality in the Netherlands. It is in the province of South Holland, part of the North Sea mouth of the Rhine–Meuse–Scheldt delta, via the ''"New Meuse"'' inland shipping channel, dug to connect to the Meuse first, but now to the Rhine instead. Rotterdam's history goes back to 1270, when a dam was constructed in the Rotte. In 1340, Rotterdam was granted city rights by William IV, Count of Holland. The Rotterdam–The Hague metropolitan area, with a population of approximately 2.7 million, is the 10th-largest in the European Union and the most populous in the country. A major logistic and economic centre, Rotterdam is Europe's largest seaport. In 2020, it had a population of 651,446 and is home to over 180 nationalities. Rotterdam is known for its university, riverside setting, lively cultural life, maritime heritage and modern architecture. The near-complete destru ...

Wilton's Dok- En Werf Maatschappij
Wilton's Dok- en Werf Maatschappij was a Dutch shipbuilding company active as an independent company from 1854 till 1929. At first it was simply known as 'Wilton'. In 1921 the final Dutch name became: 'Wilton's Dok- en Werf Maatschappij NV', the equivalent of 'Wilton Engineering and Slipway Company'. Wilton started as a traditional smithy and expanded in machinery. It specialized in ship repairs, but also became a shipyard. At first only for fresh water ships. In spite of multiple name changes the company was commonly referred to as 'Wilton'. In 1929 a merger with Fijenoord led to a new company known as Wilton-Fijenoord. Founded as a smithy in Rotterdam center Bartel Wilton Sr. (1828-1898) had left Rotterdam to work on a shipyard in London. While there, his old father was living in humble circumstances near the country house of the merchant and regent Abram van Rijckevorsel (1790-1864). Van Rijckevorsel and his friend the shipping magnate Willem Ruys (1837-1901) got an idea to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilton-Fijenoord
Wilton-Fijenoord was a shipbuilding and repair company in Schiedam the Netherlands from 1929 to 1999. Presently, the shipyard of Wilton-Feijnoord is part of Damen Shiprepair Rotterdam. Merger of Wilton and Fijenoord (1929) Wilton-Fijenoord had two predecessors. Wilton's Dok- en Werf Maatschappij was the biggest predecessor of Wilton-Fijenoord, the other was the Shipyard Fijenoord. By the mid 1920s these shipyards had become rather similar. Wilton still had an advantage in ship repair, and Fijenoord was still ahead in ship construction, especially for the navy. The idea for a merger dated as far back as at least 1927. The rationale was that the still profitable Wilton company had a major overcapacity and was spread over two locations. The activities of Fijenoord could just as well be done in Schiedam. A concentration of the combined activities in Schiedam would lead to major cost savings. In 1929 talks led to an agreement for a financial merger between the companies. Shares in Wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
U-boat
U-boats were naval submarines operated by Germany, particularly in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy naval warships, they were most effectively used in an economic warfare role (commerce raiding) and enforcing a naval blockade against enemy shipping. The primary targets of the U-boat campaigns in both wars were the merchant convoys bringing supplies from Canada and other parts of the British Empire, and from the United States, to the United Kingdom and (during the Second World War) to the Soviet Union and the Allied territories in the Mediterranean. German submarines also destroyed Brazilian merchant ships during World War II, causing Brazil to declare war on both Germany and Italy on 22 August 1942. The term is an anglicised version of the German word ''U-Boot'' , a shortening of ''Unterseeboot'' ('under-sea-boat'), though the German term refers to any submarine. Austro-Hungarian Navy submarines were also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine Snorkel
A submarine snorkel is a device which allows a submarine to operate submerged while still taking in air from above the surface. British Royal Navy personnel often refer to it as the snort. A concept devised by Dutch engineers, it was widely used on German U-boats during the last year of World War II and known to them as a ''Schnorchel''. History Until the advent of nuclear power, submarines were designed to operate on the surface most of the time and submerge only for evasion or for daylight attacks. Until the widespread use of radar after 1940, at night a submarine was safer on the surface than submerged, because sonar could detect boats underwater but was almost useless against a surface vessel. However, with continued radar improvement as the war progressed, submarines (notably, the German U-boats in the Battle of the Atlantic) were forced to spend more time underwater, running on electric motors that gave speeds of only a few knots and very limited range. An early subma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nazi Germany
Nazi Germany (lit. "National Socialist State"), ' (lit. "Nazi State") for short; also ' (lit.

ORP Sęp (1938)
ORP ''Sęp'' was an serving in the Polish Navy during World War II. In Polish her name means ''Vulture''. Construction Built at the Dutch shipyard Rotterdamsche Droogdok Maatschappij, she was laid down in November 1936 and launched on 17 October 1938. In early 1939 the Polish team supervising the building of the ship noticed a significant slowdown in her construction, which it attributed to the action of German agents. Because of fears that German pressure on the Netherlands would prevent that country from delivering the ship into Polish hands, it was decided to bring the ship to Poland earlier than scheduled. On 2 April, the ship left for deep water sea trials in Horten, Norway, with a crew of Polish sailors and Dutch technicians, under the Dutch flag. After completing the trials, the Polish crew took control of the ship (against the will of the Dutch technicians on board), raised the Polish flag and left Horten to rendezvous with the Polish destroyer outside the harbou ...

Schiedam
Schiedam () is a city and municipality in the west of the Netherlands. It is located in the Rotterdam–The Hague metropolitan area, west of Rotterdam, east of Vlaardingen, and south of Delft. In the south the city is connected with the village of Pernis by the Beneluxtunnel. The city is known for its historical center with canals, and for having the tallest windmills in the world. Schiedam is also well known for the distilleries and malthouses and production of jenever ( gin) − such as the internationally renowned Ketel One − so much so that in French and English the word ''schiedam'' (usually without a capital ''s-'') refers to the town's Holland gin. This was the town's main industry during the early Industrial Revolution in the 18th and 19th century, a period to which it owed its former nickname "Zwart Nazareth" or "Black Nazareth". Furthermore, the city is known for Saint Lidwina, one of the most famous Dutch saints (her relics are located in the Liduina Basilica in S ...

Netherland Line
The Stoomvaart Maatschappij Nederland ("Netherlands Steamship Company") or SMN, also known as the Netherland Line or Nederland Line, was a Dutch shipping line that operated from 1870 until 1970, when it merged with several other companies to form what would become Royal Nedlloyd.Nedlloyd itself later merged with Peninsular and Oriental Steam Navigation Company (P&O) to become P&O Nedlloyd, now a part of Maersk. The company's motto, ''Semper Mare Navigandum'' ("Always sail the seas"), conveniently fitted the same initials. Foundation Introduction The SMN was founded on May 13, 1870 in Amsterdam for the trade between North Western Europe and the former Dutch East Indies (modern Indonesia) via the newly opened Suez Canal. Construction of the Suez Canal had started on 25 April 1859. Together with the development of steam engines with lower coal consumption (the compound engine), the realization of a suitable canal would make sailing ships obsolete on the passage to the East Indie ...

Floating Sheerleg
A floating sheerleg (also: shearleg) is a floating water vessel with a crane built on shear legs. Unlike other types of crane vessel, it is not capable of rotating its crane independently of its hull. There is a huge variety in sheerleg capacity. The smaller cranes start at around 50 tons in lifting capacity, with the largest being able to lift 10,000 tons. The bigger sheerlegs usually have their own propulsion system and have a large accommodation facility on board, while smaller units are floating pontoons that need to be towed to their workplace by tugboats. Sheerlegs are commonly used for salvaging ships, assistance in shipbuilding Shipbuilding is the construction of ships and other Watercraft, floating vessels.
