Koopvaarders Lock
Koopvaarders Lock in Den Helder, Netherlands connects the Noordhollandsch Kanaal to the Nieuwediep. There were 4 locks at Nieuwediep carrying this name. Context Nieuwediep is connected to Amsterdam The Dutch Navy constructed the deep water harbor of Nieuwediep from 1781 to 1785. From 1792 onwards, a navy base was created. First at the Nieuwe Werk of 1792, which had its own lock, later at Willemsoord. After the Netherlands became independent again in 1813, King William I took a closer look into the commercial possibilities at Nieuwediep. By 1818 he had connected Nieuwediep to the system of inland waterways and ultimately Amsterdam. This was done by building a second lock at Nieuwediep, a canal, an inland lock at 't Zand and some other facilities. The Navy Lock (Koopvaarders Lock I) The first Koopvaarders Lock opened in October 1817. At first it had the same name as the Koopvaarders Lock treated in this article. It was called (Commercial Lock with fan gates), but al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noordhollandsch Kanaal
The Noordhollandsch Kanaal ("Great North Holland Canal") is a canal originally meant for ocean-going ships. It is located in North Holland, Netherlands. The canal was of great significance in Dutch history. Location The canal is about 75 kilometers long. Nowadays, it is a canal that connects several cities in North Holland. It starts at Den Helder in the north, and then goes through Alkmaar and Purmerend, and ends opposite the IJ at Amsterdam. As such it is one of the many canals in the Netherlands. However, from its construction till about 1880 it had a totally different character, because it was a canal meant for ocean-going ships. Ships would sail from the Americas or East-Asia, and then be towed along the canal from Den Helder to Amsterdam. Context and Plans The Zuiderzee becomes less navigable During the 17th century the Zuiderzee became ever less navigable for sea-going ships of the cities on its shores. Amsterdam was especially challenged by the shallows near ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Last (unit)
The last was a Dutch unit of mass, volume, and number, and a large English unit of weight, mass, volume, and number. It referred to standardized amounts of ships' lading and varied by commodity and over time. Name The term derives from Old English ',''Oxford English Dictionary'', 3rd ed. "last, ''n.2''" Oxford University Press (Oxford), 2014. ultimately from a Proto-Germanic root reconstructed as *''hlaþ''- or *''hlað-'' ("to place").''Oxford English Dictionary'', 1st ed.

Willem I Lock
Willem I Lock is a monumental lock in Amsterdam-Noord. Location Willem I Lock is just across the IJ from railway Station Amsterdam Centraal. The lock is on the IJ-end of the Noordhollandsch Kanaal, the other end is near Den Helder, where the Wadden Sea and North Sea meet. The location of Willem I lock is explained by the desire to place the IJ-end of the canal as close as possible to the Port of Amsterdam. For this it was built on the headland Volewijck, sticking out into the IJ. History First plan for a lock near the IJ In late 1818 an inland waterway connection was established between Nieuwediep and Amsterdam. The complete connection could only be used by barges and small vessels that could lower their masts. However, the northernmost section could also be used by ships which could pass the (later) navy lock at Nieuwediep. That same year, King William I asked Inspector General Jan Blanken for proposals that would enable ships to reach Alkmaar, and to pass it. The k ...

Corrosion
Corrosion is a natural process that converts a refined metal into a more chemically stable oxide. It is the gradual deterioration of materials (usually a metal) by chemical or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and preventing corrosion. In the most common use of the word, this means electrochemical oxidation of metal in reaction with an oxidant such as oxygen, hydrogen or hydroxide. Rusting, the formation of iron oxides, is a well-known example of electrochemical corrosion. This type of damage typically produces oxide(s) or salt(s) of the original metal and results in a distinctive orange colouration. Corrosion can also occur in materials other than metals, such as ceramics or polymers, although in this context, the term "degradation" is more common. Corrosion degrades the useful properties of materials and structures including strength, appearance and permeability to liquids and gases. Many structural ...

Willemsoord Dry Dock I
Willemsoord Dry Dock I is a historic dry dock in Willemsoord, Den Helder, Netherlands. It was constructed from 1813 till 1822, under the direction of Jan Blanken, and was part of the former Rijkswerf Willemsoord. Context Nieuwediep In 1781-1785 the harbor of Nieuwediep was created just east of Den Helder. It was meant for heavy warships, which had trouble reaching their home towns on the Zuiderzee. These home towns (like Amsterdam) vehemently opposed the construction of a competing harbor, and wanted Nieuwediep's function to remain strictly limited to harboring heavy warships. Nevertheless, from 1792 onward, some field fortifications were made to protect the harbor. A careening facility called or was also created. Here ships could enter at high tide, be put on their side at low tide and careen while a lock door prevented the flood from returning. The 1799 the Anglo-Russian invasion of Holland led to the capture of the base at Nieuwediep and the surrender of the cornered ...

Foot (unit)
The foot ( feet), standard symbol: ft, is a unit of length in the British imperial and United States customary systems of measurement. The prime symbol, , is a customarily used alternative symbol. Since the International Yard and Pound Agreement of 1959, one foot is defined as 0.3048 meters exactly. In both customary and imperial units, one foot comprises 12 inches and one yard comprises three feet. Historically the "foot" was a part of many local systems of units, including the Greek, Roman, Chinese, French, and English systems. It varied in length from country to country, from city to city, and sometimes from trade to trade. Its length was usually between 250 mm and 335 mm and was generally, but not always, subdivided into 12 inches or 16 digits. The United States is the only industrialized nation that uses the international foot and the survey foot (a customary unit of length) in preference to the meter in its commercial, engin ...
