Yinson Integrated Annual Report 2025

61 INTEGRATED ANNUAL REPORT 2025 BUSINESS REVIEW | YINSON PRODUCTION Anchored in operational excellence 5-year average fleet technical uptime (%) FY2025 99.6 FY2024 99.7 FY2023 99.6 FY2022 99.8 FY2021 99.8 Beyond new asset deliveries, our operational FPSOs maintained high standards for safety and efficiency. FY2025 is yet another strong year with industry-leading uptime for the Yinson Production fleet, with a 99.4% technical uptime and 99.6% average 5-year technical uptime. This year, we introduced a new metric to measure the fleet’s commercial performance against its ordinary contractual day rates - Fleet commercial performance - which takes into account contractual bonuses and maluses received during the year. In FY2025, we achieved a fleet commercial performance of 101.6%. FPSO Anna Nery also completed its first planned production shutdown on 12 February 2025, ahead of schedule, which followed meticulous planning, effective collaboration and a strong focus on safety. The shutdown maintained a perfect safety record throughout the execution of its comprehensive scope of work. Maintaining industry-leading safety standards LTIF IOGP benchmark FY2025 0.13 0.24 FY2024 0.05 0.28 FY2023 0 0.24 TRIF IOGP benchmark FY2025 0.47 0.94 FY2024 0.31 0.99 FY2023 0.15 0.85 In FY2025, our safety performance continued to exceed industry benchmarks for Lost Time Injury Frequency (“LTIF“) and Total Recordable Injury Frequency (“TRIF“). The slight rise in TRIF and LTIF are reflective of the reduction in manhours from 39 million in FY2024 to 23 million in FY2025, which aligns with our expectations as our intensive projects phases are completed and the assets move on to the operations phase. We also acknowledge a fatal incident involving a subcontractor at a third-party fabrication facility, where Yinson had no direct operational control. Despite receiving immediate medical assistance, the individual tragically passed away. This isolated incident does not diminish the overall stability of our safety performance or our commitment to the highest standards of occupational health and safety. It also highlights the need to extend our safety influence across all areas of our operations. Occupational Health & Safety, pg 89. We are pleased to highlight some significant achievements in our operational safety record. FPSO John Agyekum Kufuor reached an impressive milestone of five years without LTI on 7 August 2024 while FPSO Anna Nery celebrated one year without recordable incidents. FPSO Helang and Miri operations team was awarded the Best Contractor Award at the 2024 Health Safety and Environment Forum hosted by ENEOS Xplora (formerly known as JX Nippon) in September 2024. The award highlights over four years of incident-free operations, including 36 successful offtakes, and the safe export of over 10 million barrels of Layang crude oil and 150,000 million standard cubic feet of gas. Steady environmental performance FY2025 33.2 FY2024 33.9 3.6 6.3 15.7 14.3 Our fleet has performed well in terms of environmental metrics with most assets meeting expectations. Our fleet emission intensity recorded a slight decrease of 2.06% compared to FY2024. The trend suggests our improving fleet emission efficiency. One notable success was the completion of gas infrastructure for one of our assets, enabling gas reinjection into injection wells and significantly reducing flaring. We have marginally missed our stringent internal target for oil in water concentration for produced water of <15 ppm. We remain committed to the target and will continue to monitor this metric. While we are performing well overall, we remain focused on optimising efficiency and ensuring compliance across all operations. In partnership with our clients, we are increasingly incorporating low-carbon and efficiency technologies from our Zero Emissions FPSO Concept. Our most advanced asset, Agogo FPSO, will have the widest range of emissions-reducing technologies in our fleet so far, including a pilot post-combustion carbon capture system. * Yinson Production-operated FPSOs.
