Maritime Call Sign
Maritime call signs are call signs assigned as unique identifiers to ships and boats. All radio transmissions must be individually identified by the call sign. Merchant and naval vessels are assigned call signs by their national licensing authorities. History One of the earliest applications of radiotelegraph operation, long predating broadcast radio, were marine radio stations installed aboard ships at sea. In the absence of international standards, early transmitters constructed after Guglielmo Marconi's first trans-Atlantic message in 1901 were issued arbitrary two-letter calls by radio companies, alone or later preceded by a one-letter company identifier. These mimicked an earlier railroad telegraph convention where short, two-letter identifiers served as Morse code abbreviations to denote the various individual stations on the line (for instance, AX could represent Halifax). "N" and two letters would identify U.S. Navy; "M" and two letters would be a Marconi station. On Apr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Well Intervention
A well intervention, or well work, is any operation carried out on an oil or gas well during, or at the end of, its productive life that alters the state of the well or well geometry, provides well diagnostics, or manages the production of the well. Types of well intervention Pumping Pumping is the simplest form of intervention as it does not involve putting hardware into the well itself. Frequently it simply involves rigging up to the kill wing valve on the Christmas tree and pumping in a fluid determined necessary for the particular well. Wellhead and Christmas tree maintenance The complexity of wellhead and Christmas tree maintenance can vary depending on the condition of the wellheads. Scheduled annual maintenance may simply involve greasing and pressure testing the valve on the hardware. Sometimes the downhole safety valve is pressure tested as well. Slickline Slickline operations may be used for fishing, gauge cutting, setting or removing plugs, deploying or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Sea
The North Sea lies between Great Britain, Norway, Denmark, Germany, the Netherlands and Belgium. An epeiric sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, covering . It hosts key north European shipping lanes and is a major fishery. The coast is a popular destination for recreation and tourism in bordering countries, and a rich source of energy resources, including wind and wave power. The North Sea has featured prominently in geopolitical and military affairs, particularly in Northern Europe, from the Middle Ages to the modern era. It was also important globally through the power northern Europeans projected worldwide during much of the Middle Ages and into the modern era. The North Sea was the centre of the Vikings' rise. The Hanseatic League, the Dutch Republic, and the British each sought to gain command of the North Sea and access t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aberdeen, Scotland
Aberdeen (; sco, Aiberdeen ; gd, Obar Dheathain ; la, Aberdonia) is a city in North East Scotland, and is the third most populous city in the country. Aberdeen is one of Scotland's 32 local government council areas (as Aberdeen City), and has a population estimate of for the city of Aberdeen, and for the local council area making it the United Kingdom's 39th most populous built-up area. The city is northeast of Edinburgh and north of London, and is the northernmost major city in the United Kingdom. Aberdeen has a long, sandy coastline and features an oceanic climate, with cool summers and mild, rainy winters. During the mid-18th to mid-20th centuries, Aberdeen's buildings incorporated locally quarried grey granite, which may sparkle like silver because of its high mica content. Since the discovery of North Sea oil in 1969, Aberdeen has been known as the offshore oil capital of Europe. Based upon the discovery of prehistoric villages around the mouths of the rivers ...

Wireline (cabling)
In the oil and gas industry, the term wireline usually refers to the use of multi-conductor, single conductor or slickline cable, or "wireline", as a conveyance for the acquisition of subsurface petrophysical and geophysical data and the delivery of well construction services such as pipe recovery, perforating, plug setting and well cleaning and fishing. The subsurface geophysical and petrophysical information results in the description and analysis of subsurface geology, reservoir properties and production characteristics. Associated with this, "wireline logging" is the acquisition and analysis of geophysical and petrophysical data and the provision of related services provided as a function of along-hole depth. There are four basic types of wireline: multi-conductor, single conductor, slickline and braided line. Other types of wireline include sheathed slickline and fibre-optic lines. Multi-conductor lines consist of external armor wires wound around a core of typically 4- o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slickline
{{more citations needed, date=April 2012 Slickline refers to a single strand wire which is used to run a variety of tools down into the wellbore for several purposes. It is used during well drilling operations in the oil and gas industry. In general, it can also describe a niche of the industry that involves using a slickline truck or doing a slickline job. Slickline looks like a long, smooth, unbraided wire, often shiny, silver/chrome in appearance. It comes in varying lengths, according to the depth of wells in the area it is used (it can be ordered to specification) up to 35,000 feet in length. It is used to lower and raise downhole tools used in oil and gas well maintenance to the appropriate depth of the drilled well. In use and appearance it is connected by a drum as it is spooled off the back of the slickline truck to the wireline sheave, a round wheel grooved and sized to accept a specified line and positioned to redirect the line to another sheave that will allow the sl ...

Coiled Tubing
In the oil and gas industries, coiled tubing refers to a very long metal pipe, normally in diameter which is supplied spooled on a large reel. It is used for interventions in oil and gas wells and sometimes as production tubing in depleted gas wells. Coiled tubing is often used to carry out operations similar to wirelining. The main benefits over wireline are the ability to pump chemicals through the coil and the ability to push it into the hole rather than relying on gravity. Pumping can be fairly self-contained, almost a closed system, since the tube is continuous instead of jointed pipe. For offshore operations, the 'footprint' for a coiled tubing operation is generally larger than a wireline spread, which can limit the number of installations where coiled tubing can be performed and make the operation more costly. A coiled tubing operation is normally performed through the drilling derrick on the oil platform, which is used to support the surface equipment, although on p ...
