Vlissingen Naval Base
Vlissingen Naval Base (Marine Etablissement Vlissingen) was a base for the Admiralty of Zeeland, and later the Dutch Navy. It has a number of major marine facilities of historic significance. It housed a shipyard for the Admiralty of Zeeland, and the national shipyard Rijkswerf Zeeland. Shipyard de Schelde would take over the grounds of the Rijkwerf, and still continues to build warships as Damen Schelde Naval Shipbuilding. Location of Vlissingen The location of Vlissingen on the mouth of the Schelde means that it can easily be reached by the biggest ships. Such was the case in the Middle Ages and this is still the case in the 21st century. What made Vlissingen a safe place for ships were the man-made facilities of the port. Large numbers of warships could lay in ordinary in the wet dock, and then be repaired either in the dry dock or on one of the slipways of the Rijkswerf.

Vlissingen
Vlissingen (; zea, label= Zeelandic, Vlissienge), historically known in English as Flushing, is a municipality and a city in the southwestern Netherlands on the former island of Walcheren. With its strategic location between the Scheldt river and the North Sea, Vlissingen has been an important harbour for centuries. It was granted city rights in 1315. In the 17th century Vlissingen was a main harbour for ships of the Dutch East India Company (VOC). It is also known as the birthplace of Admiral Michiel de Ruyter. Vlissingen is mainly noted for the yards on the Scheldt where most of the ships of the Royal Netherlands Navy (''Koninklijke Marine'') are built. Geography The municipality of Vlissingen consists of the following places: * City: Vlissingen * Villages: Oost-Souburg, Ritthem, and West-Souburg * Hamlet: Groot-Abeele History The fishermen's hamlet that came into existence at the estuary of the Schelde around AD 620 has grown over its 1,400-year history into the thir ...

Teredo Navalis
''Teredo navalis'', commonly called the naval shipworm or turu, is a species of saltwater clam, a marine bivalve mollusc in the family '' Teredinidae''. This species is the type species of the genus '' Teredo''. Like other species in this family, this bivalve is called a shipworm, because it resembles a worm in general appearance, while at the anterior end it has a small shell with two valves which is adept at boring through wood. This species may have originated in the northeast Atlantic Ocean, but has spread around the world. It tunnels into underwater piers and pilings and is a major cause of damage and destruction to submarine timber structures and the hulls of wooden boats. Description ''Teredo navalis'' has an elongated, reddish, wormlike body which is completely enclosed in a tunnel it has made in floating or submerged timber. At the front end of the animal are two triangular, calcareous plates. These are up to long and correspond to the valves of other bivalve mollus ...

Constantin Guys
Constantin Guys (born Ernest-Adolphe Guys de Saint-Hélène, December 3, 1802 – December 13, 1892) was a French Crimean War correspondent, water color painter and illustrator for British and French newspapers. Biography Guys was born and baptized in Vlissingen, the son of François Lazare Guys and his second wife, Elisabeth Bétin. His father had been appointed civilian chief of the French Navy in Rochefort in 1795 and was stationed in Vlissingen from 1800 until 1806, after which the family moved to Calais. At the age of 20, Constantin served in the cavalry, but only a little later toured in Greece with Lord Byron. His career as an artist didn't start until he was about 40. Baudelaire called him the "painter of modern life," and wrote a long essay on Guys in which he extensively praised his works, under the pseudonym "Monsieur G". Robert de Montesquiou wrote a review of Guys that acknowledged Baudelaire's essay, compared Guys favorably to Whistler, and emphasized his portr ...

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. It normally takes place in a specialized facility known as a shipyard. Shipbuilders, also called shipwrights, follow a specialized occupation that traces its roo ..., loading and unloading large cargo into ships, and bridge building. They have grown consid ...

Marine Chronometer
A marine chronometer is a precision timepiece that is carried on a ship and employed in the determination of the ship's position by celestial navigation. It is used to determine longitude by comparing Greenwich Mean Time (GMT), or in the modern world its successor Coordinated Universal Time (UTC), and the time at the current location found from observations of celestial bodies. When first developed in the 18th century, it was a major technical achievement, as accurate knowledge of the time over a long sea voyage was vital for effective navigation, lacking electronic or communications aids. The first true chronometer was the life work of one man, John Harrison, spanning 31 years of persistent experimentation and testing that revolutionized naval (and later aerial) navigation and enabling the Age of Discovery and Colonialism to accelerate. The term '' chronometer'' was coined from the Greek words '' χρόνος (chronos)'' (meaning time) and '' meter'' (meaning measure) in 171 ...

Time Ball
A time ball or timeball is a time-signalling device. It consists of a large, painted wooden or metal ball that is dropped at a predetermined time, principally to enable navigators aboard ships offshore to verify the setting of their marine chronometers. Accurate timekeeping is essential to the determination of longitude at sea. Although time balls have since been replaced by electronic time signals, some time balls have remained operational as historical tourist attractions. History The fall of a little ball was in antiquity a way to show to people the time. Ancient Greek clocks had this system in the main square of a city, as in the city of Gaza in the post-Alexander era, and as described by Procopius in his book on Edifices. Time ball stations set their clocks according to transit observations of the positions of the sun and stars. Originally they either had to be stationed at the observatory, or had to keep a very accurate clock at the station which was set manually to observ ...

Buttress
A buttress is an architectural structure built against or projecting from a wall which serves to support or reinforce the wall. Buttresses are fairly common on more ancient buildings, as a means of providing support to act against the lateral (sideways) forces arising out of inadequately braced roof structures. The term ''counterfort'' can be synonymous with buttress and is often used when referring to dams, retaining walls and other structures holding back earth. Early examples of buttresses are found on the Eanna Temple (ancient Uruk), dating to as early as the 4th millennium BC. Terminology In addition to flying and ordinary buttresses, brick and masonry buttresses that support wall corners can be classified according to their ground plan. A clasping or clamped buttress has an L shaped ground plan surrounding the corner, an angled buttress has two buttresses meeting at the corner, a setback buttress is similar to an angled buttress but the buttresses are set back from ...

Ship Camel
A ship camel is an external flotation tank that can be fitted to a ship to increase her buoyancy or reduce her draught. Its inner walls may be concave and curve to fit the hull of the ship. The ship camels are partially sunk using water ballast, fitted to the ship in opposed pairs, and the water is then pumped out again. The increased displaced volume provided by the camels allows the system to float at a reduced draught. History The ship camel was invented in 1690 by Meeuwis Meindertsz Bakker to allow large ships of the line to cross shallow banks that isolated the harbour of Amsterdam from the open sea. In April, he tested the device with the large ship of the line ''Princess Maria'', which was sailed over the shallow waters of Pampus in the Zuiderzee. The Admiralty of Amsterdam awarded a reward to Bakker for his invention. The camel was mostly used in the Dutch Golden Age for accessing the shallow waters at Pampus, which were unreachable for large merchant ships. Instead of ...

Caisson (lock Gate)
A caisson is a form of lock gate. It consists of a large floating iron or steel box. This can be flooded to seat the caisson in the opening of the dock to close it, or pumped dry to float it and allow it to be towed clear of the dock. Chevron gates Most locks are closed by chevron or mitre gates rather than by caissons. These are pairs of hinged gates that form a "V" shape, with the deeper water outside the V. Water pressure thus holds them closed. These gates can be opened and closed quickly, so they are used for canal locks, to change levels, and also for most freight docks. As the function of a freight dock is to ''enclose'' deep water, such gates point inwards. A graving or dry dock, in contrast, ''excludes'' water, and so their gates point outwards. Hinged gates are relatively complicated, and so expensive, to construct. Large gates require powered machinery to operate them, machinery that must be provided for each set of gates. Chevron gates can also only resist deep w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
