Transocean owns or has partial ownership interests in and operates a fleet of 27 mobile offshore drilling units comprising 20 ultra deepwater drillships and seven harsh environment semisubmersibles. Its core business is contracting these rigs together with associated equipment and trained work crews to drill oil and gas wells for exploration and development projects worldwide. The firm focuses on technically demanding sectors such as ultra deepwater and harsh environment drilling where its specialized vessels deliver high performance and reliability.
Transocean generates revenue primarily through dayrate contracts for its drilling services. Under these agreements customers pay a specified daily rate for the use of the drilling unit equipment and crew while the rig is actively engaged in drilling operations. Revenue is directly linked to the utilization rate of the fleet and the number of contract days executed each period. As of December 31 2025 the company reported a contract backlog of approximately six point two nine billion dollars reflecting the aggregate value of future performance obligations under existing contracts.
