This work aims to fill theoretical and operational gaps in managing the interfaces and shared impacts of safety and security risks in Liquefied Natural Gas (LNG) ports which threaten the supply chain with high risks and disruption. It proposes a holistic and integrated approach to security risk assessment and management in LNG ports and marine terminals, which are strategically located midstream the supply chain and present credible targets for international terrorism. Rising global demand has focused on safety and security concerns spanning LNG production, transport, distribution, and related infrastructures. To prevent interruptions and to raise supply chain robustness and resilience, LNG port safety and security risk management is viewed from a supply chain perspective and the relationships and shared impacts are examined. A case study embracing multiple research methods engaged expert practitioners in reformulating the prevailing dichotomous approach to risk management. A holistic approach, considered essential, was encapsulated in a practical conceptual model for LNG port integrated safety and security risks and emergency management, including risk prevention, mitigation, emergency planning and response, and port business continuity. Implementation is urgent at LNG ports lacking this approach.
