Drillships
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. ulsa, 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 ( Glomar) II'', a 5,500-deadweight-ton vessel, costing around $4.5 million. Built by a Gulf Coast shipyard, the vessel was almost twice the size o ...

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 ...

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 seas. Offshore drilling presents 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 barges and swamp barges), combined drilling and production facilities either bottom founded or floating platforms, and deepwater mobile offshore drilling units (MODU) including semi-submersibles or drillships. The ...

Semi-submersible
Semi-submersible may refer to a self-propelled vessel, such as: *Heavy-lift ship, which partially submerge to allow their cargo (another ship) to float into place for transport *Narco-submarine, some of which remained partially on the surface *Semi-submarine, which cannot fully submerge *Semi-submersible naval vessel, which partially submerges to minimize being observed *Semi-submersible platform, which is typically transported to a location where it is placed in service *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 platfor ..., a large structure with facilities for well drilling to explore, extract, store, and process petroleum and natural gas, in deeper water (more than 1,500 metres (4,900 ft)), the semisubmersibles or drillships are maintained at the required drilling loc ...

Discoverer Enterprise
''Discoverer Enterprise'' is a fifth generation deepwater double hulled dynamically positioned drillship (ASTANO FPSO design) owned and operated by Transocean Offshore Deepwater Drilling Inc., capable of operating in moderate environments and water depths up to 3,049 m (10,000 ft) using an , 15,000 psi blowout preventer (BOP), and a outside diameter (OD) marine riser. From 1998 to 2005 the vessel was Panama-flagged and currently flies the flag of convenience of the Marshall Islands. ''Discoverer Enterprise'' has two sister ships, ''Discoverer Spirit'' completed in 1999, and ''Discoverer Deep Seas'' completed in 2000. The ship was the first to offer a dual drilling derrick capability. The dual derricks allowed simultaneous operations to be performed, and according to Transocean increased efficiency by 40 percent. The US$360 million ship gives its name to the Enterprise Class of large deepwater drillships. ''Deepwater Horizon'' spill response The ship operates ...

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 du ...

Türkiye Petrolleri Anonim Ortaklığı
Türkiye Petrolleri Anonim Ortaklığı (TPAO) (Turkish Petroleum Corporation) was founded in 1954 by Law No. 6327 with the responsibility of being involved in hydrocarbon exploration, drilling, production, refinery and marketing activities of oil and gas in Turkey as the national company. Being an important actor of the national economy, TPAO achieved many “firsts” of the Turkish oil industry. The company, its history reaching back over a half century, has given rise to seventeen major companies, including Petkim, Tüpraş and POAŞ to Turkey. Until 1983, as an integrated oil company, it was engaged in all the activity fields of oil industry from exploration to production, refinery, marketing and transportation. Today, TPAO is a national oil company involved in merely upstream (exploration, drilling, well completion and production) sector. Operations The core activities of TPAO are: * Exploration, drilling, production and well completion * Natural gas storage * Particip ...

International Ocean Discovery Program
The International Ocean Discovery Program (IODP) is an international marine research collaboration dedicated to advancing scientific understanding of the Earth through drilling, coring, and monitoring the subseafloor. The research enabled by IODP samples and data improves scientific understanding of changing climate and ocean conditions, the origins of ancient life, risks posed by geohazards, and the structure and processes of Earth's tectonic plates and uppermost mantle. IODP began in 2013 and builds on the research of four previous scientific ocean drilling programs: Project Mohole, Deep Sea Drilling Project, Ocean Drilling Program, and Integrated Ocean Drilling Program. Together, these programs represent the longest running and most successful international Earth science collaboration. Scientific scope The scientific scope of IODP is laid out in the program's science plan, ''Illuminating Earth's Past, Present, and Future''. The science plan covers a 10-year period of operati ...
