What is the Transocean Founding Story?
The origins of Transocean's rich history can be traced back to 1953 with the establishment of The Offshore Company by Southern Natural Gas Company. This pivotal moment marked an early commitment to the burgeoning field of offshore oil and gas extraction, setting the stage for future industry leadership.
The Genesis of Transocean
The foundation of what would become Transocean was laid in 1953 when Southern Natural Gas Company, later known as Sonat, formed The Offshore Company. This strategic move followed the acquisition of DeLong-McDermott, a joint drilling operation, underscoring a forward-thinking approach to offshore exploration.
- The Offshore Company was established in 1953 by Southern Natural Gas Company.
- This formation was a direct result of acquiring the DeLong-McDermott joint drilling operation.
- Key predecessor entities include Southeastern Drilling Company (Sedco), founded in 1947, and the French firm Forages et Exploitations Pétrolières (Forex), established in 1942.
- The Offshore Company's initial focus was on designing and constructing advanced drilling equipment.
The Offshore Company's initial business model was centered on the innovation and construction of cutting-edge drilling equipment.
