A risk mitigation framework for LNG operations: Conceptualizing technical audits and HSE integration

Abstract

Liquefied Natural Gas (LNG) operations present unique challenges due to the inherent risks associated with handling, storage, and transportation of cryogenic and highly flammable materials. Ensuring operational safety and mitigating risks are critical to preventing incidents that could lead to catastrophic consequences. This study proposes a robust risk mitigation framework tailored for LNG operations, emphasizing the integration of technical audits with Health, Safety, and Environment (HSE) protocols. The framework adopts a proactive approach by conceptualizing technical audits as a systematic tool for identifying and addressing potential hazards across the LNG value chain. The proposed framework incorporates a comprehensive risk assessment methodology that aligns with international safety standards, such as ISO 31000 and ISO 45001. It highlights the critical role of integrating HSE strategies into routine operational workflows to enhance safety performance and compliance. The study further explores the application of advanced technologies, including digital twins and predictive analytics, to optimize technical audits and facilitate real-time risk monitoring. By embedding HSE integration into the technical audit process, the framework ensures a holistic view of operational risks, encompassing both technical and human factors. It underscores the importance of fostering a safety culture through stakeholder engagement, continuous training, and effective communication channels. Additionally, the framework proposes a tiered auditing system that prioritizes high-risk areas, ensuring resource allocation is both strategic and effective. The findings reveal that integrating technical audits with HSE practices significantly improves hazard identification, incident response, and overall risk management. The study also demonstrates the scalability of the framework, making it adaptable to various LNG operational contexts, from production facilities to transportation and storage terminals. This research contributes to the body of knowledge on LNG safety and provides practical insights for industry stakeholders, policymakers, and HSE professionals aiming to enhance operational resilience. Future work could explore the framework’s applicability to emerging LNG technologies, such as floating storage and regasification units (FSRUs), to address evolving industry challenges.
