1. Berkut Oil Rig

Location and Design

The Berkut oil rig, located off the Russian Pacific coast near the island of Sakhalin, is the largest oil platform in the world. Weighing approximately 200,000 tons and situated 35 meters deep from the seafloor, this engineering marvel has an estimated maximum oil extraction capacity of 4.5 million tons annually.

The platform is designed to withstand subarctic conditions, including 60-foot waves and temperatures as low as -44 degrees Celsius. Its gravity-based structure (GBS) is fixed to the seabed, providing stability and durability in extreme weather and environmental challenges.

Construction and Operation

Constructed to tap the vast Arkutun-Dagi oil reserves, the Berkut platform was one of the most expensive and challenging projects undertaken by a consortium of major oil companies from the US, Japan, India, and Russia. The $12 billion project, named after the Russian word for "Golden Eagle," is expected to generate more than $9 billion in revenue over the next ten years.

The platform's massive topside measures 105 meters in length, 60 meters in width, and 144 meters in height. It weighs over 42,780 metric tons and houses various modules, emergency equipment, a security system, a rig, a processing unit, a living area, a helipad, and other facilities.

2. Stones Floating Production, Storage, and Offloading Facility (FPSO)

Location and Design

Shell operates the Stones FPSO in the US Gulf of Mexico, approximately 322 kilometres off the coast of New Orleans. It holds the record for the planet's deepest operating oil and gas project, reaching an astonishing depth of 9,500 feet below sea level.

The FPSO, named Turritella, is a converted Suezmax tanker secured in place using buoyant turret mooring (BTM) technology. It connects to two wells with plans to expand to six over time and utilises a flexible "steel lazy wave riser" to carry oil and gas to the surface.

Capacity and Production

The Stones project can produce an estimated 60,000 barrels of oil equivalent per day at peak production. The field is estimated to hold more than 2 billion barrels of oil equivalent, significantly contributing to global oil production.

3. Perdido Oil Platform

Location and Design

Located in the Gulf of Mexico, approximately 200 miles south of Galveston, Texas, the Perdido oil platform is the world's deepest spar-type platform. Operated by Shell, it is moored in 2,450 meters (8,000 feet) of water and produces oil and gas from depths of between 2,300 and 2,800 meters (7,500 to 9,500 feet).

The Perdido's cylindrical spar measures 170 meters (555 feet) and is moored securely to the sea floor. Its hull has a height of 267 meters, almost as tall as the Eiffel Tower, and weighs 22,000 tons.

Capacity and Production

The platform can handle 100,000 barrels of oil and 200 million cubic feet of gas daily. It serves as a hub for three fields in the Gulf of Mexico - Great White, Tobago, and Silvertip - and is connected to 22 oil wells through a 44-kilometre (27-mile) network of pipelines on the ocean floor.

4. Olympus Oil Platform (Mars B)

Location and Design

The Olympus oil platform, also known as Mars B, is owned by Shell and operates within the Mars B field in the Gulf of Mexico. The platform was built to extend the life of the Mars field to at least and increase production capacity.

Weighing 120,000 tons and standing at a height of 406 feet from the base of the hull to the top of the derrick, Olympus is one of the largest floating deep-water platforms in the world. The platform operates in a water depth of around 3,100 feet and produces approximately 100,000 barrels of oil equivalent per day.

Capacity and Production

Since its inception in , the Olympus platform has produced over 700 million barrels of oil. It supports 192 offshore jobs and has a combined deck area of 342,000 square feet, larger than an NFL Superdome.

5. Hibernia Platform

Location and Design

The Hibernia platform, situated about 196 miles east of Newfoundland, Canada, is the world's largest offshore platform and the first iceberg-resistant gravity-based structure. It operates in the North Atlantic and has a total weight of 496,040 tons.

The platform is designed to withstand collisions with icebergs up to 1.1 million tons in weight. It features a 106-meter cement caisson made of concrete, protected by a surrounding steel structure to resist icebergs. The gravity-based structure (GBS) can store 1.4 million barrels of oil.

Capacity and Production

The Hibernia platform has operated since November , producing over barrels of oil daily. It is expected to continue producing oil beyond , contributing significantly to global oil production.

6. Petronius Platform

Location and Design

The Petronius platform, located in the Gulf of Mexico close to New Orleans, is one of the tallest free-standing structures in the world. Constructed between and , this fixed-compliant tower-type rig weighs 47,399 tons and operates at a depth of 1,754 feet.

Petronius' unique design allows it to sway with the tidal currents instead of resisting movement due to waves or winds. It stands at an impressive height of 2,001 feet and features a multi-deck topside containing essential equipment, living quarters for workers, pipelines, an operations room, and a drilling rig.

Capacity and Production

The Petronius platform can handle 60,000 barrels of oil equivalent and 3,100,000 cubic meters of oil and natural gas every day. It remains an essential contributor to global oil production.

7. Baldpate Platform

Location and Design

Located off the coast of Louisiana, the Baldpate platform was the first-ever free-standing offshore compliant tower. Baldpate, designed by Hudson Engineering in Houston, Texas, stands in an impressive 1,650 feet of water. The platform reached its production peak in .

Capacity and Production

Baldpate's unique design and construction have made it an essential part of the global oil production landscape. Its continued operation contributes to the overall global oil supply.
