Technology Focus: Offshore Facilities (September 2026)

_ Within the oil and gas industry, the arena of offshore facilities is subject to the same emphases and initiatives as its terrestrial counterpart. Decarbonization and automation have become focal points for marine structures and systems. This year’s selections, contributed to by reviewer Jefferson Couto, reflect an emphasis on emissions reduction and facilities repurposing for carbon capture, use, and storage (CCUS) projects as well as advances in automation and unattended operations. Paper SPE 37089 explores the application of a modular, high-temperature gas-cooled reactor to a Very Large Crude Carrier-class floating production, storage, and offloading vessel (FPSO). Highlighting a coherent case-study framework rather than detailed design optimization, the authors write that economics suggest that, for FPSOs burning associated gas, nuclear power remains disadvantaged in some aspects compared with gas turbines, but that a nuclear system’s associated, quantifiable emissions reductions, partially monetizable through carbon pricing and credit mechanisms, can offset a significant share of nuclear capital cost and make nuclear-powered FPSOs a credible decarbonization option for high-throughput offshore production. Combined-cycle power-generation technology, in which gas turbines and steam turbines are used together to convert fuel into electricity, is the focus of paper SPE 225466. The paper describes the potential of combined-cycle technology in CCUS applications for offshore facilities, especially when used in tandem with an exhaust-gas-recycling approach. The authors write that combined-cycle technology, which offers 22–25% reduced fuel consumption and CO2 emissions, is poised to make important strides into expanding offshore CCUS efforts. Finally, paper SPE 225805 discusses the process of assessing an aging offshore complex for the largest CCUS project in southeast Asia. Structural-integrity evaluations were used to check corrosion status as the platform nears the end of its design life. The paper uses the structural-integrity-management framework to evaluate the chosen platforms, highlighting their potential and limitations for CCUS purposes based on in-service assessments. The authors write that successful repurposing demands a demonstrated capacity to safely contain and manage new operational loads, resist CO2’s chemical and physical effects, and withstand cumulative aging for the entire service duration. Recommended papers highlight reuse of decommissioned facilities for CCUS, autonomous marine interventions, and a conceptual study for an unattended FPSO offshore Brazil.
