Pipe-laying Ship
A pipelaying ship is a maritime vessel used in the construction of subsea infrastructure. It serves to connect oil production platforms with refineries on shore. To accomplish this goal a typical pipelaying vessel carries a heavy lift crane, used to install pumps and valves, and equipment to lay pipe between subsea structures. Lay methods consist of J-lay and S-lay and can be reel-lay or welded length by length. Pipelaying ships make use of dynamic positioning systems or anchor spreads to maintain the correct position and speed while laying pipe. Recent advances have been made, with pipe being laid in water depths of more than 2,500 metres. The term "pipelaying vessel" or "pipelayer" refers to all vessels capable of laying pipe on the ocean floor. It can also refer to "dual activity" ships. These vessels are capable of laying pipe on the ocean floor in addition to their primary job. Examples of dual activity pipelayers include barges, modified bulk carriers, modified drillships ...

Subsea
Subsea technology involves fully submerged ocean equipment, operations, or applications, especially when some distance offshore, in deep ocean waters, or on the seabed. The term ''subsea'' is frequently used in connection with oceanography, marine or ocean engineering, ocean exploration, remotely operated vehicle (ROVs) autonomous underwater vehicles (AUVs), submarine communications or power cables, seafloor mineral mining, oil and gas, and offshore wind power. Oil and gas Oil and gas fields reside beneath many inland waters and offshore areas around the world, and in the oil and gas industry the term ''subsea'' relates to the exploration, drilling and development of oil and gas fields in these underwater locations. Under water oil fields and facilities are generically referred to using a ''subsea'' prefix, such as ''subsea well'', ''subsea field'', ''subsea project'', and ''subsea developments.'' Subsea oil field developments are usually split into ''Shallow water'' and ''D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heavy Lift
In transportation, heavy lift refers to the handling and installation of heavy items which are indivisible, and of weights generally accepted to be over 100 tons and of widths/heights of more than 100 meters. These oversized items are transported from one place to another (sometimes across country borders) then lifted or installed into place. Characteristic for heavy lift goods is the absence of standardization which requires an individual transport planning. Typical cargo Typical heavy-lift cargo includes generators, turbines, reactors, boilers, towers, casting, heaters, presses, locomotives, boats, satellites, military personnel and equipment. In the offshore industry, parts of oil rigs and production platforms are also lifted; some of these are also removed at the end of an installation's working life. Recent notable lifts have included several of >2000 metric tons in the de-commissioning of the North West Hutton oil field in the British sector of the North Sea. Transport ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. 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 ...

HYSY 202
HYSY 202 (Hai Yang Shi You 202) is a non self propelled, shallow water pipe laying barge, owned by CNOOC, the national oil exploration company of China. Built in 2012, it is one of the six large crane barges owned by COOEC and CNOOC, namely "HYSY201", "HYSY 202", " Lanjing", "Blue Xinjiang", "Binhai 109", "HYSY286", "HYSY289" and "HYSY291". Equipped with a large 1200 tonnes lifting capacity crane, a long stinger and extensive equipment for laying sub sea oil and gas pipelines, HYSY 202 has been engaged in numerous projects across the world, including building some of the largest bridges off the coast of China, and laying sub sea oil pipelines in the South China Sea.

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or ...

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.
