Transocean Ltd.

Transocean Ltd. is a leading international provider of offshore contract drilling services for oil and gas wells, specializing in technically demanding sectors such as ultra-deepwater and harsh environment drilling. The company's mission is to be the premier offshore drilling company by delivering worldwide, rig-based well construction services through motivated personnel, quality equipment, and innovative technology, with a particular focus on challenging environments. Transocean Ltd. is headquartered in Steinhausen, Switzerland.

Transocean's primary business involves contracting its drilling rigs, associated equipment, and work crews on a dayrate basis to facilitate the drilling of oil and gas wells. The company operates a highly versatile fleet of mobile offshore drilling units, which includes ultra-deepwater drillships, semi-submersible rigs, and high-specification jackup rigs. These services are provided to major integrated energy companies and independent operators across the globe.

In a significant leadership transition, Keelan Adamson assumed the role of President and Chief Executive Officer in the second quarter of 2025, succeeding Jeremy Thigpen, who transitioned to Executive Chair of the Board of Directors. The company has recently secured substantial contract awards, contributing to its backlog, and is actively focused on debt reduction. Notable contract wins in Norway, Brazil, and the Eastern Mediterranean have added considerable backlog. Furthermore, a pending merger with Valaris is anticipated to enhance scale and generate synergies, reinforcing Transocean's position as a global leader in offshore drilling.
