Drillship
A drillship is a merchant vessel designed for use in exploratory offshore drilling of new oil and gas wells or for scientific drilling purposes. In recent years the vessels have been used in deepwater and ultra-deepwater applications, equipped with the latest and most advanced dynamic positioning systems. History The first drillship was the ''CUSS I'', designed by Robert F. Bauer of Global Marine in 1955. The ''CUSS I'' had drilled in 400-foot-deep waters by 1957.Schempf, F. (2007). Pioneering Offshore: The Early Years. [Tulsa, OK]: PennWell Custom Pub. Robert F. Bauer became the first president of Global Marine in 1958. In 1961 Global Marine started a new drillship era. They ordered several self-propelled drillships each with a rated centerline drilling of 20,000 foot-wells in water depths of 600 feet. The first was named ''CUSS (GlobalSantaFe Corporation, Glomar) II'', a 5,500-deadweight-ton vessel, costing around $4.5 million. Built by a Gulf Coast shipyard, the vesse ...

Oil Platform
An oil platform (also called an oil rig, offshore platform, oil production platform, etc.) 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 linked by bridge 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 to the ocean floor, consist of an artificial island, or 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 connections. These sub-sea facilities may include one or more subsea wells or manifold centres for multiple wells. Offshore drillin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Offshore Drilling
Offshore drilling is a mechanical process where a wellbore is drilled below the seabed. It is typically carried out in order to explore for and subsequently extract petroleum that lies in rock formations beneath the seabed. Most commonly, the term is used to describe drilling activities on the continental shelf, though the term can also be applied to drilling in lakes, inshore waters and Inland sea, inland seas. Offshore drilling presents all environmental challenges, both offshore and onshore from the produced hydrocarbons and the materials used during the drilling operation. Controversies include the ongoing US offshore drilling debate. There are many different types of facilities from which offshore drilling operations take place. These include bottom founded drilling rigs (Jackup rig, jackup barges and swamp Barge, barges), combined drilling and production facilities either bottom founded or floating platforms, and deepwater mobile offshore drilling units (MODU) including Sem ...

Türkiye Petrolleri Anonim Ortaklığı
TPAO or Turkish Petroleum Corporation has been established in order to perform hydrocarbon exploration, drilling, production, refinery and marketing activities on behalf of the Turkish Republic with the law 6327 in 1954. Many milestones in Turkish Petroleum Industry has been brought to real by TPAO. Foundation of industry giants like PETKİM, TÜPRAŞ, PETROL OFİSİ are amongst these milestones. TPAO continued exploration, production, refining, marketing and transportation activities until 1983 as an integrated oil company. TPAO has been acting as a state owned exploration and production oil company since the legal regulations made in 1983 and some other more recent changes. TPAO’s primary goal is to reduce Turkey’s oil and gas import. Exploration In 2013, the company purchased the seismography, seismographic research vessel, research/survey vessel RV Barbaros Hayreddin Paşa, RV ''Barbaros Hayreddin Paşa'' worth US$130 million for gas and oil field exploration in Black ...

Dynamic Positioning
Dynamic positioning (DP) is a computer-controlled system to automatically maintain a vessel's position and heading by using its own propellers and thrusters. Position reference sensors, combined with wind sensors, motion sensors and gyrocompasses, provide information to the computer pertaining to the vessel's position and the magnitude and direction of environmental forces affecting its position. Examples of vessel types that employ DP include ships and semi-submersible mobile offshore drilling units (MODU), oceanographic research vessels, cable layer ships and cruise ships. The computer program contains a mathematical model of the vessel that includes information pertaining to the wind and current drag of the vessel and the location of the thrusters. This knowledge, combined with the sensor information, allows the computer to calculate the required steering angle and thruster output for each thruster. This allows operations at sea where mooring or anchoring is not feasible ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jackup Rig
A jackup rig or a self-elevating unit is a type of mobile platform that consists of a buoyant hull fitted with a number of movable legs, capable of raising its hull over the surface of the sea. The buoyant hull enables transportation of the unit and all attached machinery to a desired location. Once on location the hull is raised to the required elevation above the sea surface supported by the sea bed. The legs of such units may be designed to penetrate the sea bed, may be fitted with enlarged sections or footings, or may be attached to a bottom mat. Generally jackup rigs are not self-propelled and rely on tugs or heavy lift ships for transportation. Jackup platforms are almost exclusively used as exploratory oil and gas drilling platforms and as offshore and wind farm service platforms. Jackup rigs can either be triangular in shape with three legs or square in shape with four legs. Jackup platforms have been the most popular and numerous of various mobile types in existence. T ...

Moon Pool
A moon pool is an equipment deployment and retrieval feature used by oil platforms, marine drilling platforms, drillships, diving support vessels, fishing vessels, oceanography, marine research and underwater exploration or research vessels, and underwater habitats. It is also known as a wet porch. It is an opening found in the floor or base of the hull (watercraft), hull, platform, or chamber giving access to the water below. Because of its stable location, it safely allows technicians or researchers to lower tools and measuring instruments, instruments into the sea. Moon pools also provide shelter and protection so that even if the ship is in high seas or surrounded by ice, researchers can work in comfort rather than on a deck exposed to the elements. A moon pool also allows divers, diving bells, ROVs, or small submersible craft to enter or leave the water easily and in a more protected environment. Moon pools can be used in chambers below sea level, especially for the use of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
