Onrust Dock Of 5,000 Tons
Onrust Dock of 5,000 tons, was a floating dry dock which served in the Dutch East Indies from 1881 till 1924. Context In 1876 the Dutch navy started to think of a new dock for the Dutch East Indies. This would become ''Onrust Dock of 5,000 tons''. At the time it was clear that the naval situation in the East Indies was changing. The ironclad HNLMS Prins Hendrik der Nederlanden was sailing to the Dutch East Indies. The first of the unprotected Atjeh-class cruisers were under construction, and the small battleship HNLMS Koning der Nederlanden had been launched. These ships all had about 3,500 tons displacement, Koning der Nederlanden displaced 5,300 tons. It explains the size and name of ''Onrust Dock of 5,000 tons''. A dry dock that could lift 5,000 tons could lift all these ships, except (perhaps) for the Koning der Nederlanden. When ''Onrust Dock of 5,000 tons'' had been assembled in the Dutch East Indies it was said to be meant for the two armored ships. The order for ''Onrust ...

Van Vlissingen En Dudok Van Heel
Van Vlissingen en Dudok van Heel was a famous nineteenth-century Dutch machine factory. It built steam engines and machinery for the sugar industry and for maritime purposes, as well ships, rolling stock and large metal structures like the Moerdijk bridge and a floating dock. In 1871 it was reorganized to become the public company Koninklijke Fabriek van Stoom- en andere Werktuigen. In a second reorganization in 1890, parts of it were saved and continued under the name Koninklijke Nederlandsche Fabriek van Werktuigen en Spoorwegmaterieel, renamed to Werkspoor in 1927. Van Vlissingen en Dudok van Heel Early years The company was founded as the 'Van Vlissingen' company in 1826. The founder was Paul van Vlissingen (1797–1876), who was also one of the founders of the Amsterdamsche Stoomboot Maatschappij (ASM).

Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ra ...

Hopper Barge
A hopper barge is a kind of non-mechanical ship or vessel that cannot move around by itself, unlike some other types of barges, that is designed to carry materials, like rocks, sand, soil and rubbish, for dumping into the ocean, a river or lake for land reclamation. Hopper barges are seen in two distinctive types; raked hopper or box hopper barges. The raked hopper barges move faster than the box hoppers; they are both designed for movement of dry bulky commodities. There are several "hoppers" or compartments between the fore and aft bulkhead of the barge. On the bottom of the barge hull, there is (are) also a large "hopper door(s)", opening downwards. The doors are closed while the vessel is moving, so she can carry the materials that are to be dumped. The door(s) open when the ship has arrived at the spot where the materials are to be dumped. Split barges serve the same purpose, but instead of a door in the hull's bottom, the hull of the whole barge splits longitudinal ...

Tanjung Priok
Tanjung Priok is a district of North Jakarta, Indonesia. It hosts the western part of the city's main harbor, the Port of Tanjung Priok (located in Tanjung Priok District and Koja District). The district of Tanjung Priok is bounded by Laksamana Yos Sudarso Tollway and Sunter River canal to the east, by Kali Japat, Kali Ancol, and the former Kemayoran Airport to the southwest, by Sunter Jaya Road and Sunter Kemayoran Road to the south, and by Jakarta Bay to the north. History Before human development, the coastal area of what is now Tanjung Priok was an area of brackish water with swamp and mangrove forest. The old harbor of Jakarta During the colonial era, Batavia at first relied on the Sunda Kelapa harbor area. This meant that Batavia had a harbor system like many others cities. I.e. an anchorage at sea at some distance from the city, and a city harbor where smaller ships could attach to a quay. It meant that big ships like the Dutch East Indiamen and later ships safely anc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russian Cruiser Vladimir Monomakh
''Vladimir Monomakh'' (russian: Владимир Мономах) was an armoured cruiser built for the Imperial Russian Navy during the 1880s. The vessel was named after Vladimir II Monomakh, Grand Prince of Kiev. She spent most of her career in the Far East, although the ship was in the Baltic Sea when the Russo-Japanese War began in 1904. ''Vladimir Monomakh'' was assigned to the Third Pacific Squadron and participated in the Battle of Tsushima in May 1905. She was tasked to protect the Russian transports and was not heavily engaged during the daylight portion of the battle. The ship was torpedoed during the night and was scuttled the following morning by her captain to prevent her capture by the Japanese. Design and description ''Vladimir Monomakh'' was classified as a semi-armored frigate and was an improved version of the preceding . The ship was designed with high endurance and high speed to facilitate her role as a commerce raider able to outrun enemy battleships. She w ...

Russian Cruiser Minin
} The Russian cruiser ''Minin'' (russian: Минин) was an armored cruiser built for the Imperial Russian Navy during the 1860s and 1870s. She was renamed ''Ladoga'' in 1909 when converted to a minelayer. The ship was sunk in 1915 when she struck a mine laid by a German submarine in the Baltic Sea. Design and description Originally designed as a sister ship to the broadside ironclad , the navy was dissatisfied with that ship as it believed that foreign developments had made her obsolete. So the ship was redesigned as a low-freeboard twin-turret ship with full rigging, much like the ill-fated British ship . Already launched when ''Captain'' capsized in a storm in 1870, ''Minin'' was reconstructed as an armored cruiser with her armament on the broadside and improved machinery.Watts, p. 68 The ship had an overall length of , a beam of and a draft of .Silverstone, p. 358 She displaced at deep load. Her hull was sheathed with copper to reduced biofouling and her crew numbered a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Onrust Dock Of 5,000 Tons With Kosmopoliet III
The ''Onrust'' (; en, Restless) was a Dutch ship built by Adriaen Block and the crew of the '' Tyger'', which had been destroyed by fire in the winter of 1613. The ''Onrust'' was the first ship to be built in what is now New York State, and the first fur trading vessel built in America. The construction took four months in the winter of 1614 somewhere in New York Bay. Help from the local Native population is surmised based on the relationship developed by Jon Rodriquez, left on the island during a previous voyage. The ''Onrust'' was 44.5 feet long and capable of carrying 16 tons. In 1614, Block sailed through the whirlpools ( Hellegat) on the East River, and into Long Island Sound. There he named Block Island for himself. Block was also the first European to venture up the Connecticut River. He managed to get as far as the Enfield rapids, about 60 miles up the river. Besides finding several inland water routes, creating trading networks and mapping native villages, the two f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spanish Cruiser Gravina
''Gravina'' was a unprotected cruiser of the Spanish Navy. Technical characteristics ''Gravina'' was built by the Thames Ironworks & Shipbuilding & Engineering Co. Ltd. at Leamouth, London in the United Kingdom. Her keel was laid in 1881. She had one rather tall funnel. She had an iron hull and was rigged as a barque. She and the lead ship of the class, , also built in the United Kingdom, were differently armed and slightly faster than the final six ships of the class, all of which were built in Spain. Operational history Not long after her completion, ''Gravina'' was based in the Philippines. She had a short life, sinking in a typhoon A typhoon is a mature tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere.

Volharding Dock
''Volharding Dock'', was a floating dry dock built for the Nederlands Indische Droogdok Maatschappij (NIDM) in the 1870s. It was the smallest of two unique tower dry docks, and the only one that would actually be put in use. Context Dry dock capacity in the Dutch East Indies In the 1850s there were only two dry docks in the Dutch East Indies, both made of wood. Meanwhile the demand for dry dock capacity increased sharply. In the 1860s one of the first iron dry docks ever built appeared in the Dutch East Indies. It was the commercial iron dry dock for the shipping line of Cores de Vries, built by Randolph, Elder and Co. After being assembled in the Indies, she sunk during her trial in Surabaya in 1863. The Dutch Navy reacted to the demand by sending the iron Onrust Dock of 3,000 tons. This iron dry dock arrived at Onrust Island near Batavia on 4 November 1869. She would prove remarkably durable, but was owned by the navy. The NIDM Since 1 January 1869 civilian ships were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolphin (structure)
A dolphin is a group of pilings arrayed together to serve variously as a protective hardpoint along a dock, in a waterway, or along a shore; as a means or point of stabilization of a dock, bridge, or similar structure; as a mooring point; and as a base for navigational aids. Structure Dolphins typically consist of a number of piles driven into the seabed or riverbed, and connected above the water level to provide a platform or fixing point. The piles can be untreated or pressure treated timber piles, or steel or reinforced concrete piles. Smaller dolphins can have the piles drawn together with wire rope, but larger dolphins are typically fixed using a reinforced concrete capping or a structural steel frame. Access to a dolphin may be via a pedestrian bridge, particularly in the case of mooring dolphins, but is often by boat. Use As mooring point Dolphins are usually installed to provide a fixed structure when it would be impractical to extend the shore to provide a dry- ...
