Cyber-Physical Systems (CPSs) are getting increasingly complex and interconnected. Consequently, their inherent safety risks and security risks are so intertwined that the conventional analysis approaches which address them separately may be rendered inadequate. STPA (Systems-Theoretic Process Analysis) is a top-down hazard analysis technique that has been incorporated into several recently proposed integrated Safety and Security (S&S) analysis methods. This paper presents a novel methodology that leverages not only STPA, but also custom matrices to ensure a more comprehensive S&S analysis. The proposed methodology is demonstrated using a case study of particular commercial cloud-based monitoring and control system for residential energy storage systems.

Through the introduction to stevedoring process of LNG terminal, the preliminary hazard analysis technique is applied to distinguish and identify three potential dangerous factors which could cause fire and explosion, and corresponding preliminary hazard lists are then established respectively. In the end, the risk levels of fire and explosion are found out to be betweenand, and the appropriate precautionary measures are given to different risk level, those provide scientific reference for putting forward safety management decision effectively.

Accident Causation

Accident models provide a conceptual representation of accident causation. They have been applied to environments that have been exposed to poisonous or dangerous substances that are hazardous in nature. The home environment refers to the indoor space with respect to the physical processes the of indoor climate, e.g., temperature change, which are not hazardous in general. However, it can be hazardous when the physical process is in some states, e.g., a state of temperature that can cause heat stroke. If directly applying accident models in such a case, the physical processes are missing. To overcome this problem, this paper proposes an accident model by extending the state-of-the-art accident model, i.e., Systems-Theoretic Accident Model and Process (STAMP) with considering physical processes. Then, to identify causes of abnormal system behaviors that result in physical process anomalies, a hazard analysis technique called System-Theoretic Process Analysis (STPA) is tailored and applied to a smart home system for indoor temperature adjustment. The analytical results are documented by a proposed landscape genealogical layout documentation. A comparison with results by applying the original STPA was made, which demonstrates the effectiveness of the tailored STPA to apply in identifying causes in our case.

The number of Floating Production Storage and Offloading units (FPSOs) operating worldwide has been increasing due to the fact that they are well recognized as one of the most economical systems to develop offshore (ultra) deep water areas lacking infrastructure. In order to comply with the regulations, especially the Classification Society rules, and to monitor the hull integrity, all the cargo tanks must be submitted to periodical surveys on a continuous base. Eventually during this survey, some anomalies may be found, such as cracks and thickness loss in structural elements that will require repairs. This study provides a brief review of the methodology provided by the Guidelines for Formal Safety Assessment (FSA) proposed by IMO (2002) and its application to the activities performed to survey and repair a cargo tank of an operating FPSO. A detailed description of these activities is provided in order to define the scope and frontiers of this study. Special attention is paid to the first step of the FSA methodology and the “Preliminary Hazard Analysis” technique is applied to the mentioned activities.
