We have served the oil & gas industry since the early 20th century, when we began building storage tanks for the young but flourishing oil business; and by the 1940's we were building and installing offshore platforms in the Gulf of Mexico. Today, we offer a comprehensive range of technology and EPCI services for the upstream oil & gas sector, with a focus on:

  • Offshore oil & gas production systems, including jackets, topsides and floating production, storage and offloading (FPSO) vessels, as well as subsea production systems
  • Onshore oil & gas field production
  • Offshore and onshore pipelines
  • Natural gas processing
  • Storage

Within these focus areas, we can provide any combination of front-end design, engineering, procurement, fabrication, construction, installation, hook-up, start-up and commissioning services across all phases of the project life cycle. Through a strategic partnership with Lummus Technology, we provide licensed process technology and proprietary know-how for gas processing in the upstream market. 

Offshore Oil & Gas Production

Our capabilities in the offshore market are focused on the design, engineering, construction, transportation, installation, hook-up and commissioning of fixed platforms, floating production, storage and offloading (FPSO) systems, and subsea pipelines and field production systems.

Onshore Oil & Gas Production

McDermott has decades of experience in onshore oil and gas field development, oil & gas processing terminals, and underground gas storage.

Natural Gas Processing

Through our strategic agreement with Lummus Technology, we have access to a broad technology portfolio—including gas conditioning and treating, fractionation, deep ethane extraction and LPG recovery, and liquid product treating—which enables us to offer solutions across the natural gas value chain.


McDermott has the most extensive global experience of any tank construction company in the industry, having built in excess of 46,000 storage tanks under the CB&I brand in more than 100 countries on all seven continents.
