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 destruction ...

Dredging
Dredging is the excavation of material from a water environment. Possible reasons for dredging include improving existing water features; reshaping land and water features to alter drainage, navigability, and commercial use; constructing dams, dikes, and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value. In all but a few situations the excavation is undertaken by a specialist floating plant, known as a dredger. Dredging is carried out in many different locations and for many different purposes, but the main objectives are usually to recover material of value or use, or to create a greater depth of water. Dredges have been classified as suction or mechanical. Dredging has significant environmental impacts: it can disturb marine sediments, leading to both short- and long-term water pollution, destroy important seabed ecosystems, and can release human-sourced toxins captured in the sediment.

DEME
In Ancient Greece, a deme or ( grc, δῆμος, plural: demoi, δημοι) was a suburb or a subdivision of Athens and other city-states. Demes as simple subdivisions of land in the countryside seem to have existed in the 6th century BC and earlier, but did not acquire particular significance until the reforms of Cleisthenes in 508 BC. In those reforms, enrollment in the citizen-lists of a deme became the requirement for citizenship; prior to that time, citizenship had been based on membership in a phratry, or family group. At this same time, demes were established in the main city of Athens itself, where they had not previously existed; in all, at the end of Cleisthenes' reforms, Athens was divided into 139 demes, to which one can be added Berenikidai (established in 224/223 BC), Apollonieis (201/200 BC), and Antinoeis (added in 126/127). The establishment of demes as the fundamental units of the state weakened the ''gene'', or aristocratic family groups, that had dominated t ...

Royal IHC
Royal IHC or Koninklijke IHC, previously IHC Holland (1943–1995), IHC Holland Merwede (1995–2005) and IHC Merwede (2005–2014) is a Dutch shipbuilding company with headquarters in Kinderdijk. It focuses on the development, design and construction of ships for the dredging and offshore industries. IHC Holland partnership (1943–1965) The Industriële Handels Combinatie (IHC) in the Hague was a partnership. The idea came up when the Billiton company made plans for tin mining after the war, and a number of shipyards each deemed themselves incapable to build the required vessels on their own after the war. The partnership consisted of 6 small companies which were all strong players in dredging, but wanted to be more efficient. In sales e.g. it was very inefficient for all these relatively small companies to have their own agents abroad. The partnership consisted of: * Conrad Shipyard in Haarlem * Gusto Shipyard Gusto Shipyard, previously A.F. Smulders, was a shipbuilding ...

Krimpen Aan Den IJssel
Krimpen aan den IJssel () is a town and municipality in the western Netherlands, in the province of South Holland. The municipality had a population of in , and covers an area of of which is water. History Krimpen is first mentioned in a document from 1277. Like other hamlets, many different spellings of its name have occurred over time, among which the name ''Tingenijssel'' deviated the most from today's spelling. The municipality is on the south shore of the river Hollandse IJssel. For many centuries, the only buildings in Krimpen were farm houses built along the river dike. They formed more or less autonomous communities along the dike. Before the 20th century, the two principal industrial employers were the brick factory ''Mijnlieff'' and the shipyard ''Van der Giessen de Noord''. In the beginning of the 20th century development began inland from the river dikes, and the municipality began to lose its agricultural character. During the North Sea flood of 1953, the tidal b ...

Liquefied Natural Gas
Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4, with some mixture of ethane, C2H6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport. It takes up about 1/600th the volume of natural gas in the gaseous state (at standard conditions for temperature and pressure). LNG is odorless, colorless, non-toxic and non-corrosive. Hazards include flammability after vaporization into a gaseous state, freezing and asphyxia. The liquefaction process involves removal of certain components, such as dust, acid gases, helium, water, and heavy hydrocarbons, which could cause difficulty downstream. The natural gas is then condensed into a liquid at close to atmospheric pressure by cooling it to approximately ; maximum transport pressure is set at around (gauge pressure), which is about one-fourth times atmospheric pressure at sea level. The gas extracted from underground hydrocarbon deposits contains a varying mix of hy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Fuel
Diesel fuel , also called diesel oil, is any liquid fuel specifically designed for use in a diesel engine, a type of internal combustion engine in which fuel ignition takes place without a spark as a result of compression of the inlet air and then injection of fuel. Therefore, diesel fuel needs good compression ignition characteristics. The most common type of diesel fuel is a specific fractional distillate of petroleum fuel oil, but alternatives that are not derived from petroleum, such as biodiesel, biomass to liquid (BTL) or gas to liquid (GTL) diesel are increasingly being developed and adopted. To distinguish these types, petroleum-derived diesel is sometimes called petrodiesel in some academic circles. In many countries, diesel fuel is standardised. For example, in the European Union, the standard for diesel fuel is EN 590. Diesel fuel has many colloquial names; most commonly, it is simply referred to as ''diesel''. In the United Kingdom, diesel fuel for on-road use is c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bunker Oil
Fuel oil is any of various fractions obtained from the distillation of petroleum (crude oil). Such oils include distillates (the lighter fractions) and residues (the heavier fractions). Fuel oils include heavy fuel oil, marine fuel oil (MFO), bunker fuel, furnace oil (FO), gas oil (gasoil), heating oils (such as home heating oil), diesel fuel and others. The term ''fuel oil'' generally includes any liquid fuel that is burned in a furnace or boiler to generate heat (heating oils), or used in an engine to generate power (as motor fuels). However, it does not usually include other liquid oils, such as those with a flash point of approximately , or oils burned in cotton- or wool-wick burners. In a stricter sense, ''fuel oil'' refers only to the heaviest commercial fuels that crude oil can yield, that is, those fuels heavier than gasoline (petrol) and naphtha. Fuel oil consists of long-chain hydrocarbons, particularly alkanes, cycloalkanes, and aromatics. Small molecules, such as th ...

Ships Built In The Netherlands
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were cont ...
