McDermott Corporate Headquarters, Texas

McDermott makes offshore production facilities, pipelines, power plants, and other energy-related infrastructure. From its origins as a marine contractor in the marshlands of Texas and Louisiana, McDermott now has around 14,000 employees, making some of the largest offshore oil platforms in the world. At one time McDermott was also a major nuclear engineering services company - primarily through their Babcock and Wilcox subsidiary - until a decision was made in 2009 to spin-off B&W into a separate company, completely independent of McDermott. Its two building corporate headquarters is located just off Interstate 10, in the Energy Corridor area.
