Do you know which are the largest offshore Oil & Gas production platforms of the world?

Nearly 30% of global Oil & Gas productions comes from offshore sources. Without them, world’s economy would probably not be able to produce enough oil at economical prices to meet demand. 

But do you know which are the biggest oil and gas offshore platforms on the planet? Check out the top 5.

The Mars field was discovered by Royal Dutch Shell in 1989. Surpassing all expectation, Shell and its partner BP decided to construct the Mars B platform, ready in 2014. Standing more than 121 meters tall and weighing 119,000 tons, Mars B/Olympus platform is expected to produce more than 1 billion BOE and extend the field’s life until 2050.

Discovered in 1979, The Hibernia oil field is located about 321 km southeast of St. John’s Newfoundland, on the east of Canada, and it is co-owned by ExxonMobil, Chevron, Suncor Energy and other partners. Hibernia consists of a 37,000 tons integrated topsides facility mounted on a 600,000 tons gravity base structure. The platform was towed to its final site, and 450,000 tons of solid ballast were added to secure it in place. Inside the gravity base structure are storage tanks for 1.2 million barrels (190,000 m3) of crude oil. In 2016, Hibernia has produced its billionth barrel of oil and it is expected to continue operating until 2040.

Perdido started its producing in 2010 and it’s co-owned by Shell, Chevron, BP and others. It is one of the world’s deepest spar platforms, moored in 2,450 meters of water. The cylinder spar is almost as highas the Eiffel Tower, with a 170 meters’ tall structure.


1. The Berkut Platform in the Sea of Okhotsk on the Russian Pacific Coast – The largest floating oil platform



The Berkut Platform is the largest in the world. Owned by Rosneft, ExxonMobil and others, it is located in the Sea of Okhotsk on the Russian Pacific Coast. The platform costed an estimated 12 billion dollars to build and it weighs 200,000 tons. Berkut can withstand 18m waves, the pressure of more than 1,5m of ice, temperatures of -50°C and a magnitude 9 earthquakes. 

Constructing an Offshore Oil & Gas production platform is an audacious project. Billions of dollars on investments and a lot of years are necessary to fulfill this goal. A thoroughly knowledge of metocean condition is also obligatory for the success of the project. 

To help with this difficult and ambitious task, Open Ocean conceived Metocean Analytics, the first online offer for metocean study on-demand. Metocean Analytics gives access in just a few clicks to a catalogue of validated historical wind, wave, ocean current, temperature data, standard statistical analysis tools and an automatic report generation tool to analyse any offshore location in the world.
