A Framework for Emission Monitoring and Optimization in Energy-Intensive Floating Oil and Gas Production Systems

Authors(4) :-Andrew Tochukwu Ofoedu, Joshua Emeka Ozor, Oludayo Sofoluwe, Dazok Donald Jambol

Floating oil and gas production systems, including Floating Production Storage and Offloading (FPSO) units and Floating Liquefied Natural Gas (FLNG) facilities, play a crucial role in offshore hydrocarbon extraction. However, these systems are highly energy-intensive and contribute significantly to greenhouse gas (GHG) and pollutant emissions, posing environmental and regulatory challenges. This presents a comprehensive framework for real-time emission monitoring and optimization tailored to the complex operational environment of floating production units. The framework integrates advanced sensor technologies for continuous monitoring of key emission species such as CO₂, CH₄, NOₓ, and SOₓ, coupled with robust data acquisition and transmission protocols designed to handle the harsh offshore conditions. Data fusion techniques are employed to combine sensor outputs with operational logs and process simulations, ensuring data accuracy and reliability despite noise and missing information. Central to the framework is an emission optimization module that leverages thermodynamic and equipment performance models alongside artificial intelligence and machine learning algorithms. This module supports multi-objective optimization strategies, balancing emission reduction goals with production efficiency and operational constraints. Key optimization approaches include predictive control, load management, fuel switching, and flare minimization, enabling operators to make informed decisions that reduce environmental impact without compromising system performance. The framework’s efficacy is demonstrated through a detailed case study of a representative FPSO, showcasing significant potential for emission reduction and improved energy efficiency. Sensitivity analyses highlight the robustness of the approach under varying operational conditions and uncertainties. Finally, the review discusses practical considerations for integrating the framework with existing onboard control systems, addressing cybersecurity and operator training needs. Future directions include expanding the framework to incorporate carbon capture technologies and autonomous optimization capabilities. This framework provides a scalable and adaptable solution to support floating production operators in meeting increasingly stringent environmental regulations while optimizing operational performance, thus contributing to the sustainable development of offshore oil and gas resources.
