Petronius is a deepwater compliant tower oil platform operated by Chevron Corporation and Marathon Oil in the Gulf of Mexico, 210 km southeast of New Orleans, United States. A compliant piled tower design, it is 609.9 metres (2,001 ft) high, and was arguably the tallest free-standing structure in the world, until surpassed by the Burj Khalifa in 2008, although this claim is disputed since only 75 metres of the platform are above water. The multi-deck topsides are 64 metres by 43 metres by 18.3 metres high and hold 21 well slots, and the entire structure weighs around 43,000 tons. Around 8,000 m3 (50,000 barrels) of oil and 2,000,000 m3 (70 million cubic feet) of natural gas are extracted daily by the rig. More details

3- CNOOC 981 Oil Platform - China:

CNOOC 981 Oil Platform

On May 9, 2012 China's first deep-water drilling platform CNOOC 981 successfully completed its first drilling on the South China Sea, and the drill reached the layer of the ground 1,500 meters under the sea surface in the 6-1 area of the Li Bay of the South China Sea. It is the first time that China has carried out deep-water oil and gas exploitation independently, indicating that the deep-water strategy of China's offshore oil industry has taken a practical step. the CNOOC 981 is equipped with eight 44,000-kilowatt diesel generators whose total capacity can support the electricity consumption of a medium-sized city. It has eight thrusters, and the power of each of them is equal to that of five locomotives. More details

This is the first free-standing offshore compliant tower ever, as well as one of the tallest free-standing structures in the world. The tip of the flare boom extends 1,902ft above the seafloor. The discovery well was drilled by the semisubmersible Ocean Rover in late 1991, revealing 180ft of net pay. Total output from seven planned production wells will exceed 50,000b/d and 150,000MMSCFD. Anticipated recoverable reserves from Baldpate and Baldpate North total 104 million barrels of oil equivalent (MMBOE), of which 60% is oil and the remainder is gas. Production from the platform reached its peak in the first half of 1999, at rates approaching facility oil and gas capacities. More details

Eirik Raude Oil Rig

Deepwater oil operations are pushing technological creativity to the limits. The Eirik Raude drilling rig demonstrates the industry's ability to adapt to the planet's most rigorous conditions. The world rig market can offer a large and diverse range of units, but relatively few of these are able not only to operate in deep water but also to tackle cold, stormy weather conditions. So a group of Norwegian investors decided to construct the sensational new Eirik Raude rig, which has been specially designed to work in ultradeep water down to 3,000 metersMore details

8. Veslefrikk Platforms:

Veslefrikk Platforms

Veslefrikk platforms in the North Sea outside Bergen produce oil and gas. The oil is sent by pipeline to the Stureterminal terminal and the gas is sent by pipeline to Germany . Veslefrikk has two platforms (A and B). Veslefrikk A is a fixed steel platform ("jacket") with drilling and riser pipes. Veslefrikk B is a semi submersible platform where most of the production takes place. The platforms are connected to a bridge. This bridge is taken up in bad weather. There are also flexible risers between the platforms where the well flows from A to B, and the processed oil and gas return from B to A, where it is passed on to the pipeline. Inn to Veslefrikk A also comes from hydrocarbons from the Huldra field , which is mixed with Veslefrikk's own production and sent on. Veslefrikk A has lane lifeboats, while Veslefrikk B has plunge boats. More details

9. Emerald Vantage Jackup Rig:

Emerald Vantage Jack Up 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. More details

10. Transocean Polar Pioneer:

Transocean Polar Pioneer

The Polar Pioneer was one of two harsh environment drilling rigs Shell contracted to carry out drilling operations in the Chukchi and Beaufort Seas. But exploratory drilling in Chukchi Sea failed to find enough recoverable oil, forcing Shell to announce that it was abandoning its Alaskan Arctic drilling ambitions all together after spending about $7 billion. The Polar Pioneer received some unwanted media attention leading up to this summer’s drilling program when it was boarded by Greenpeace activists as it sailed across the Pacific Ocean and later as it was met by protests in SeattleMore details

11. Heimdal Platform:

Heimdal Platform

Heimdal (Norwegian: Heimdalfeltet) is an offshore natural gas field in the North Sea located 212 kilometers (132 mi) northwest of the Stavanger, Norway. Heimdal serves as a connection hub for processing and distribution of natural gas from satellite fields. The field was discovered in 1972. The depth of the sea at location is 120 metres (390 ft). The field was developed with an integrated drilling, production and accommodation facility with a steel jacket including a riser facility in 1999. The gas from the field is transported to Kårstø as well as to St. Fergus in Scotland. After construction of the Heimdal gas center, a new gas pipeline was connected to the existing one from Frigg gas field to St. Fergus. The gas is also transported to Grane oil field for gas injection. The condensate is sent by pipeline to Brae oilfield. Heimdal also gets gas from the Oseberg field center for further transportation through Statpipe systemMore details

14. Offshore Oil Drilling History:

Offshore Oil Drilling History

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 which 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 from the produced hydrocarbons and the materials used during the drilling operation. Controversies include the ongoing U.S. offshore drilling debate. More details

15Prirazlomnoye Oil Platform:

Prirazlomnoye Oil Platform

Prirazlomnoye field is an Arctic offshore oilfield located in the Pechora Sea, south of Novaya Zemlya, Russia, the first commercial offshore oil development in the Russian Arctic sector. The field development is based on the single stationary Prirazlomnaya platform, which is the first Arctic-class ice-resistant oil platform in the world. Commercial drilling was planned to begin in early 2012, however it was delayed at least until the Spring of 2013 due to protester's "safety concerns". Safety concerns have been raised about Prirazlomnoye platform, citing use of decommissioned equipment (the 1984 TLP upper section of the rig), however Gazprom’s oil spill response plan for Prirazlomnaya was renewed in 2014. More details
