 used on three rigs in our fleet, and, to date, we have handled over 3,000 riser joints using the system. This system eliminates the need for personnel to be in the Red Zone during riser handling operations, which are among the most physically taxing and hazardous activities offshore. We continue to engage with our customers regarding additional installations of these and other products that can make our operations safer. The combined focus on personal safety, occupational safety and process safety enables Transocean to protect people, the environments in which we work, and our assets, while conducting our work efficiently and effectively. Job roles are evaluated to identify any associated potential hazards to implement effective processes and standards to mitigate risks and support the well-being of employees while on the job. We maintain strict Transocean 2025 APB-6 Proxy Statement

requirements around personal protective equipment, task design, procedures, and equipment selection and maintenance to reduce risk and maintain a healthy environment. All rigs are staffed with a medical professional, equipped with an onboard clinic bolstered by 24/7 shore-based medical support and overseen by our Company medical director, a licensed physician. We measure our safety performance in terms of widely accepted ratios with the use of industry standards, including (a) Total Recordable Incident Rate ( “TRIR”), which represents the number of recordable work-related injuries or illnesses for every 200,000 hours worked and (b) Lost Time Incident Rate ( “LTIR”), which measures the number of incidents that result in lost time due to work-related injuries or illnesses for every 200,000 hours worked. In the year ended December 31, 2024, our TRIR was 0.15 and our LTIR was 0.00, the calculations for which were based on 11.7 million labor hours. Both TRIR and LTIR improved in 2024 versus 2023. We measure the reliability and efficiency of our operations using uptime. Uptime is measured as total operating hours, minus downtime hours, expressed as a percentage of the maximum total operating hours. Operating hours are defined as the number of hours a rig is operating under a contract. Downtime is defined as the number of hours the rig is not engaged in drilling activities, resulting from Company mechanical failure or human performance error. In the year ended December 31, 2024, uptime was 96.9% down slightly from the company-best 97.6% uptime performance in 2023. Please
