Oil Platform
An oil platform (or oil rig, offshore platform, oil production platform, and similar terms) is a large structure with facilities to extract and process petroleum and natural gas that lie in rock formations beneath the seabed. Many oil platforms will also have facilities to accommodate the workers, although it is also common to have a separate accommodation platform bridge linked to the production platform. Most commonly, oil platforms engage in activities on the continental shelf, though they can also be used in lakes, inshore waters, and inland seas. Depending on the circumstances, the platform may be fixed Platform, fixed to the ocean floor, consist of an artificial island, or floating oil production system, float. In some arrangements the main facility may have storage facilities for the processed oil. Remote subsea wells may also be connected to a platform by flow lines and by umbilical cable, umbilical connections. These sub-sea facilities may include of one or more subsea ...

Hibernia (oil Field)
Hibernia is an oil field in the North Atlantic Ocean, approximately east-southeast of St. John's, Newfoundland, Canada, in 80 m of water.Hurley, T.J., Kreisa, R.D., Taylor, G.G., and Yates, W.R.L., 1992, The Reservoir Geology and Geophysics of the Hibernia Field, Offshore Newfoundland, in ''Giant Oil and Gas Fields of the Decade, 1978-1988'', AAPG Memoir 54, Halbouty, M.T., editor, Tulsa: American Association of Petroleum Geologists, The production platform ''Hibernia'' is the world's largest oil platform (by weight) and consists of a integrated topsides facility mounted on a gravity base structure. The platform was towed to its final site, and of solid ballast were added to secure it in place. Inside the gravity base structure are storage tanks for of crude oil. Geology The field was discovered in 1979 with the Hibernia P-15 well, and is located on the Grand Banks of Newfoundland in the northwest sector of the Jeanne d'Arc Basin, the Cretaceous primary reservoir being t ...

Gravity Base Structure
A gravity-based structure (GBS) is a support structure held in place by gravity, most notably offshore oil platform, oil platforms. These structures are often constructed in fjords due to their protected area and sufficient depth. Offshore oil platforms Prior to deployment, a offshore geotechnical engineering, study of the seabed must be done to ensure it can withstand the vertical load from the structure.Dean, E.T.R. (2010). Offshore Geotechnical Engineering - Principles and Practice. Thomas Telford, Reston, VA, U.S.A., 520 p. It is then constructed with steel reinforced concrete into tanks or cells, some of which are used to control the buoyancy. When construction is complete, the structure is towed to its intended location. Wind turbines Early deployments of offshore wind power turbines used these structures. As of 2010, 14 of the world's offshore wind farms had some of their turbines supported by gravity-based structures. The deepest registered offshore wind farm with gr ...

Ocean Ranger
''Ocean Ranger'' was a semi-submersible mobile offshore drilling unit that sank in Canadian waters on 15 February 1982. It was drilling an exploration well on the Grand Banks of Newfoundland, east of St. John's, Newfoundland, for Mobil Oil of Canada, Ltd. (MOCAN) with 84 crew members on board when it sank. There were no survivors. History and design ''Ocean Ranger'' was designed and owned by Ocean Drilling and Exploration Company, Inc. (ODECO) of New Orleans. The vessel was a self-propelled large semi-submersible design with a drilling facility and living quarters. It was capable of operation beneath of ocean water and could drill to a maximum depth of . It was described by ODECO as the world's largest semi-submersible oil rig to date. Constructed for ODECO in 1976 by Mitsubishi Heavy Industries in Hiroshima, Japan, ''Ocean Ranger'' was long, wide, and high. It had twelve anchors. The weight was 25,000 tons. It was floating on two long pontoons that rested below the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N. Scientific explorations of the Atlant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Topsides
The topsides on a boat, ship, watercraft, or floating production storage and offloading (FPSO) vessel, is that part of the hull between the waterline and the deck.Rognaas, G., Xu, J., Lindseth, S., & Rosendahl, F. (2001). Mobile offshore base concepts. Concrete hull and steel topsides. ''Marine Structures'', ''14''(1-2), 5-23. It includes the visible parts of the bow, stern, sheer, and, if present, tumblehome. On an offshore oil platform, topsides refers to the upper half of the structure, above the sea level, outside the splash zone, on which equipment is installed. This includes the oil production plant, the accommodation block and the drilling rig A drilling rig is an integrated system that drills wells, such as oil or water wells, or holes for piling and other construction purposes, into the earth's subsurface. Drilling rigs can be massive structures housing equipment used to drill wat .... They are often modular in design and so can be changed out if necessary allo ...

Tonnes
The tonne ( or ; symbol: t) is a unit of mass equal to 1000 kilograms. It is a non-SI unit accepted for use with SI. It is also referred to as a metric ton to distinguish it from the non-metric units of the short ton ( United States customary units), and the long ton ( British imperial units). It is equivalent to approximately 2204.6 pounds, 1.102 short tons, and 0.984 long tons. The official SI unit is the megagram (symbol: Mg), a less common way to express the same mass. Symbol and abbreviations The BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879.Table 6 . BIPM. Retrieved on 2011-07-10. Its use is also official for the metric ton in the United States, having been adopted by the United States |

Mobil
Mobil is a petroleum brand owned and operated by American oil and gas corporation ExxonMobil. The brand was formerly owned and operated by an oil and gas corporation of the same name, which itself merged with Exxon to form ExxonMobil in 1999. A direct descendant of Standard Oil, Mobil was originally known as the Standard Oil Company of New York (shortened to Socony) after Standard Oil was Standard Oil Co. of New Jersey v. United States, split into 34 different entities in a 1911 Supreme Court decision. Socony merged with Vacuum Oil Company, from which the Mobil name first originated, in 1931 and subsequently renamed itself to Socony-Vacuum Oil Company. Over time, Mobil became the company's primary identity, which incited another renaming in 1963, this time to Mobil Corporation. Mobil credits itself with being the first company to introduce Pay at the pump, paying at the pump at its gas stations, the first company to produce jet aviation fuel, as well as the first company to intr ...

Oil Platforms Off Canada
An oil is any nonpolar chemical substance that is composed primarily of hydrocarbons and is hydrophobic (does not mix with water) & lipophilic (mixes with other oils). Oils are usually flammable and surface active. Most oils are unsaturated lipids that are liquid at room temperature. The general definition of oil includes classes of chemical compounds that may be otherwise unrelated in structure, properties, and uses. Oils may be animal, vegetable, or petrochemical in origin, and may be volatile or non-volatile. They are used for food (e.g., olive oil), fuel (e.g., heating oil), medical purposes (e.g., mineral oil), lubrication (e.g. motor oil), and the manufacture of many types of paints, plastics, and other materials. Specially prepared oils are used in some religious ceremonies and rituals as purifying agents. Etymology First attested in English 1176, the word ''oil'' comes from Old French ''oile'', from Latin ''oleum'', which in turn comes from the Greek ...
