Andrew Clennel Palmer
Andrew Clennel Palmer (26 May 1938 – 21 December 2019) was a British engineer who worked on offshore geotechnical problems of submarine pipeline design and the study of the properties of ice. He spent much of his career as a teacher and academic researcher, at the University of Liverpool, Cambridge University, the University of Manchester Institute of Science and Technology, and the National University of Singapore, punctuated by work in industry, while also serving as an expert witness and as a member of various industrial and academic committees. Early life and education Born in Colchester, Palmer was the son of Gerald Basil Coote Palmer, headmaster of Mark Hall Comprehensive School in Harlow, and Muriel née Howes. After attending the Royal Liberty School in Gidea Park, he became the first student from his school to go on to study at Cambridge University, reading Mechanical Sciences at Pembroke College and completing his undergraduate degree in 1961. He achieved f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Offshore Geotechnical Engineering
Offshore geotechnical engineering is a sub-field of geotechnical engineering. It is concerned with foundation design, construction, maintenance and decommissioning for human-made structures in the sea.Dean, p. 1 Oil platforms, artificial islands and submarine pipelines are examples of such structures. The seabed has to be able to withstand the weight of these structures and the applied loads. Geohazards must also be taken into account. The need for offshore developments stems from a gradual depletion of hydrocarbon reserves onshore or near the coastlines, as new fields are being developed at greater distances offshore and in deeper water,Randolph & Gourvenec, p. 1 with a corresponding adaptation of the offshore site investigations.Kolk & Wegerif, 2005 Today, there are more than 7,000 offshore platforms operating at a water depth up to and exceeding 2000 m. A typical field development extends over tens of square kilometers, and may comprise several fixed structures, infield f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doctorate
A doctorate (from Latin ''docere'', "to teach"), doctor's degree (from Latin ''doctor'', "teacher"), or doctoral degree is an academic degree awarded by universities and some other educational institutions, derived from the ancient formalism ''licentia docendi'' ("licence to teach"). In most countries, a research degree qualifies the holder to teach at university level in the degree's field or work in a specific profession. There are a number of doctoral degrees; the most common is the Doctor of Philosophy (PhD), awarded in many different fields, ranging from the humanities to scientific disciplines. In the United States and some other countries, there are also some types of technical or professional degrees that include "doctor" in their name and are classified as a doctorate in some of those countries. Professional doctorates historically came about to meet the needs of practitioners in a variety of disciplines. Many universities also award honorary doctorates to individuals d ...

Forties Pipeline
The Forties pipeline system (FPS) is a major pipeline transport network in the North Sea. It is owned and operated by Ineos and carries 30% of the UK's oil, or about of oil per day, to shore. It carries liquids production from 85 fields in the North Sea and several Norwegian fields on behalf of around 40 companies. The system has a capacity of 575,000 barrels of oil a day. FPS consists of a pipeline originating at APA Corporation's Forties Charlie platform. The pipeline carries crude oil , routing through the Forties Unity riser platform, to the terminal at Cruden Bay. From there unstabilised crude is co-mingled with natural gas condensate from the St Fergus terminal and pumped to the processing facility at Kinneil, Grangemouth. The onshore pipeline has three intermediate pumping stations at Netherley, Brechin and Balbeggie. History The original 32-inch pipeline was opened in 1975 to transport oil from the Forties Oil Field, the UK’s first major offshore oil field. The For ...

Oil Pipelines
Pipeline transport is the long-distance transportation of a liquid or gas through a system of pipes—a pipeline—typically to a market area for consumption. The latest data from 2014 gives a total of slightly less than of pipeline in 120 countries of the world. The United States had 65%, Russia had 8%, and Canada had 3%, thus 76% of all pipeline were in these three countries. ''Pipeline and Gas Journals worldwide survey figures indicate that of pipelines are planned and under construction. Of these, represent projects in the planning and design phase; reflect pipelines in various stages of construction. Liquids and gases are transported in pipelines, and any chemically stable substance can be sent through a pipeline. Pipelines exist for the transport of crude and refined petroleum, fuels – such as oil, natural gas and biofuels – and other fluids including sewage, slurry, water, beer, hot water or steam for shorter distances. Pipelines are useful for transporting water for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permafrost
Permafrost is ground that continuously remains below 0 °C (32 °F) for two or more years, located on land or under the ocean. Most common in the Northern Hemisphere, around 15% of the Northern Hemisphere or 11% of the global surface is underlain by permafrost, with the total area of around 18 million km2. This includes substantial areas of Alaska, Greenland, Canada and Siberia. It can also be located on mountaintops in the Southern Hemisphere and beneath ice-free areas in the Antarctic. Permafrost does not have to be the first layer that is on the ground. It can be from an inch to several miles deep under the Earth's surface. It frequently occurs in ground ice, but it can also be present in non-porous bedrock. Permafrost is formed from ice holding various types of soil, sand, and rock in combination. Permafrost contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide, making tundra soil a carbon sink. As global war ...

Trans-Alaska Pipeline
The Trans-Alaska Pipeline System (TAPS) is an oil transportation system spanning Alaska, including the trans-Alaska crude-oil pipeline, 11 pump stations, several hundred miles of feeder pipelines, and the Valdez Marine Terminal. TAPS is one of the world's largest pipeline systems. The core pipeline itself, which is commonly called the Alaska pipeline, trans-Alaska pipeline, or Alyeska pipeline, (or the pipeline as referred to in Alaska), is an long, diameter pipeline that conveys oil from Prudhoe Bay, on Alaska's North Slope, south to Valdez, on the shores of Prince William Sound in southcentral Alaska. The crude oil pipeline is privately owned by the Alyeska Pipeline Service Company. Oil was first discovered in Prudhoe Bay in 1968 and the 800 miles of 48" steel pipe was ordered from Japan in 1969 (US steel manufacturers did not have the capacity at that time) however, construction was delayed for nearly 5 years due to legal and environmental issues. The eight oil compani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stress–strain Analysis
Stress–strain analysis (or stress analysis) is an engineering discipline that uses many methods to determine the stresses and strains in materials and structures subjected to forces. In continuum mechanics, stress is a physical quantity that expresses the internal forces that neighboring particles of a continuous material exert on each other, while strain is the measure of the deformation of the material. In simple terms we can define stress as the force of resistance per unit area, offered by a body against deformation. Stress is the ratio of force over area (S = R/A, where S is the stress, R is the internal resisting force and A is the cross-sectional area). Strain is the ratio of change in length to the original length, when a given body is subjected to some external force (Strain= change in length÷the original length). Stress analysis is a primary task for civil, mechanical and aerospace engineers involved in the design of structures of all sizes, such as tunnels, bridg ...

Soil Plasticity
Soil, also commonly referred to as earth or dirt, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Some scientific definitions distinguish ''dirt'' from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three- state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists regard soil as an ecosystem. M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperature
Temperature is a physical quantity that expresses quantitatively the perceptions of hotness and coldness. Temperature is measured with a thermometer. Thermometers are calibrated in various temperature scales that historically have relied on various reference points and thermometric substances for definition. The most common scales are the Celsius scale with the unit symbol °C (formerly called ''centigrade''), the Fahrenheit scale (°F), and the Kelvin scale (K), the latter being used predominantly for scientific purposes. The kelvin is one of the seven base units in the International System of Units (SI). Absolute zero, i.e., zero kelvin or −273.15 °C, is the lowest point in the thermodynamic temperature scale. Experimentally, it can be approached very closely but not actually reached, as recognized in the third law of thermodynamics. It would be impossible to extract energy as heat from a body at that temperature. Temperature is important in all fields of natur ...

Physical Properties Of Soil
The physical properties of soil, in order of decreasing importance for ecosystem services such as crop production, are Soil texture, texture, Soil structure, structure, bulk density, Pore space in soil, porosity, consistency, temperature, colour and Soil resistivity, resistivity. Soil texture is determined by the relative proportion of the three kinds of soil mineral particles, called soil separates: sand, silt, and clay. At the next larger scale, soil structures called peds or more commonly ''soil aggregates'' are created from the soil separates when iron oxides, carbonates, clay, silica and humus, coat particles and cause them to adhere into larger, relatively stable secondary structures. Soil bulk density, when determined at standardized moisture conditions, is an estimate of soil compaction. Soil porosity consists of the void part of the soil volume and is occupied by gases or water. Soil consistency is the ability of soil materials to stick together. Soil temperature and colou ...

Churchill College
Churchill College is a constituent college of the University of Cambridge, England. It has a primary focus on science, engineering and technology, but still retains a strong interest in the arts and humanities. In 1958, a trust was established with Sir Winston Churchill as its chairman of trustees, to build and endow a college for 60 fellows and 540 students as a national and Commonwealth memorial to Winston Churchill; its Royal Charter and Statutes were approved by the Queen, in August 1960. It is situated on the outskirts of Cambridge, away from the traditional centre of the city, but close to the University's main new development zone (which now houses the Centre for Mathematical Sciences). It has of grounds, the largest area of the Cambridge colleges. Churchill was the first formerly all-male college to decide to admit women, and was among three men's colleges to admit its first women students in 1972. Within 15 years all others had followed suit. The college has a rep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
