About Transocean Ltd.

Transocean Ltd. is a leading offshore contract drilling company listed on the NYSE in the United States under the ticker RIG. For French, Belgian and Swiss investors, it is best understood as a capital-intensive energy services business whose earnings and cash flow are tied to the global offshore oil and gas investment cycle. Transocean does not produce hydrocarbons itself; instead, it provides drilling services using mobile offshore drilling units for major energy companies. Its core franchise is centered on technically demanding environments, including deepwater and ultra-deepwater projects. The company describes itself as a leading international provider of offshore contract drilling services for oil and gas wells. ([deepwater.com](https://www.deepwater.com/about-transocean?utm_source=openai)) The company’s history reflects decades of consolidation and specialization in offshore drilling. Its roots go back to legacy offshore drilling operations that evolved through a series of mergers and acquisitions into the modern Transocean platform. Today, Transocean Ltd. is a Swiss corporation with its registered office in Steinhausen, Canton of Zug, while its principal executive offices are in the United States. That corporate structure is important for investors: legal domicile is Swiss, but the stock market listing and much of the commercial visibility are American.

These assets are used to drill oil and gas wells for customers that typically include major integrated energy companies and other large upstream operators. Competitive positioning in this industry depends on the quality and age of the fleet, technical capability, uptime, safety performance, and the ability to secure long-duration contracts. Transocean’s value proposition is strongest where customers need harsh-environment or deepwater expertise, which generally creates higher barriers to entry than shallow-water drilling. ([media.corporate-ir.net](https://media.corporate-ir.net/media_files/pid/2559/interactive-presentation-2024/images/Transocean_Ltd-2025.pdf?utm_source=openai)) Geographically, the company is global, serving the main offshore basins where exploration and development spending remains active. Recent company communications have highlighted both a 2025 reporting cycle and a new award announced on May 4, 2026, for an ultra-deepwater drillship, indicating continued commercial momentum in high-specification offshore assets. Those updates matter because they suggest continued contract visibility in a market where utilization and dayrates can move materially with customer spending plans. ([deepwater.com](https://www.deepwater.com/?utm_source=openai)) Overall, Transocean is a specialized offshore drilling name with global reach, a long industry heritage and a cyclical risk profile. For investors in Europe, it offers direct exposure to offshore drilling demand, but with the usual sector sensitivities: oil and gas capex, contract renewal risk, fleet competitiveness and financial leverage. Its NYSE listing in the United States makes it accessible to international investors seeking exposure to the offshore drilling segment.
