Building anything in the oil and gas industry is an extremely difficult proposition that takes a great deal of commitment and even more expertise. Just the mere thought of the amount of planning it must take to conduct a feasibility study, carry out the front end engineering and design, invite tenders and then actually build a LNG train, petrochemicals complex or offshore facility is enough to make most construction companies decide that they would be better off sticking to apartment complexes and shopping centres.

So it is with this that ArabianOilandGas.com presents the world’s 10 largest oil and gas contractors. These are the companies that are making sure the hydrocarbons industry has the state-of-the-art facilities required to maintain its position as the world's number one provider of energy.

Like our list of the world’s 10 largest oilfield services companies we have based the list solely on the last financial year’s revenues. However, some companies on the list have higher revenues than others placed above them. This is due to the fact that being conglomerates, they have a number of major interests in other areas of industry that had to be taken into account. Daelim is a good example of this as it has a number of civil infrastructure projects etc that are not oil and gas related. Also Fluor could lay a serious claim, but seeing as it was included in the oilfield services companies list, we decided to feature another company instead. 

The information regarding each company was taken from its respective websites and as much as possible was double checked on other websites including www.britannica.com,
the Forbes Global 2000 list, Reuters and a number of other websites. 

If you think a company is missing from our list who should have been included, please feel free to leave a comment.

  1. Bechtel (USA)
  2. Technip (France)
  3. Aker Solutions (Norway)
  4. Chiyoda Corporation (Japan)
  5. SNC-Lavalin Group (Canada)
  6. J. Ray McDermott (USA)
  7. JGC Corporation (Japan)
  8. Hyundai Heavy Industries (South Korea)
  9. Foster Wheeler (USA)
  10. Daelim Industrial Company (South Korea)

1. Bechtel ($31.4 billion)

The company has its headquarters in San Francisco and was founded in the early 1900s as a contracting business concentrating on the railroad industry. Bechtel now has 44,000 employees working on projects in nearly 50 countries.

As well as still being involved in general construction Bechtel has been heavily involved with the oil and gas industry for a number of decades. The company has built refining and chemical projects, including grassroots refineries and refinery expansions and modernisations.

Other projects include gas processing plants, major oil and gas field developments, and about a third of the world’s gas liquefaction capacity — more than any other contractor. The company has also built tens of thousands of kilometers of pipeline.

Bechtel has worked on various projects across the Middle East for all the major NOCs including Saudi Aramco, Abu Dhabi National Oil Company (ADNOC) and Qatar Petroleum. 


I think TR (TECNICAS REUNIDAS SA) is also missing from your list. Having completed many major projects for ARAMCO and SA

Major EPC Companies
I think TR (TECNICAS REUNIDAS SA) is also missing from your list. Having completed many major projects for ARAMCO and SABIC ovver the last ten years, TR has much more history in KSA than recent Korean players.

What About the Saipem? is Saipem do not fall under umbrella of Top Ten EPC Contractors

CCC cannot be considered as EPC contractor, as they are the subcontractor for JGC Gulf for Civil Works. KBR and Flour deserves the place in top 10 instead of Daelim and Hyundai, Korean products do not have long durability. All SABIC projects invested on Korean's and Chinese companies to construct the projects. Chinese and Korean's have been suspended quite few years ago from ARAMCO.

World's largest oil and gas contractors
Don't you think Kellog Brown and Root (KBR) can find a place here.

John (Sep 30, 2009) British Virgin Islands

largest oil and gas contractors
What about Keppel Corporation Ltd.?

Pelle Hermanson (Sep 28, 2009) Sweden

Where's NOV or Schlumberger? Most of the companies on the list are fabricators or equipment providers, so at least National Oilwell Varco should be included.

Although SBM are involved in Marine Based production, I wondered where they are placed as a global player
