Addressing human error when collecting failure cause information in the oil and gas industry: A review of ISO 14224:2016
(Peer reviewed; Journal article, 2020-02)The international standard ISO 14224 provides key guidance on how to achieve quality information about equipment failures for decision-making in the oil and gas industry, including specific guidance on data collection ... -
Assumptions in quantitative risk assessments: When explicit and when tacit?
(Peer reviewed; Journal article, 2020)In quantitative risk assessments, several explicit assumptions need to be made, to compute the risk metrics addressed. Such assumptions may, for example, relate to the number of people exposed to specific hazards, to the ... -
Bayesian analysis: Critical issues related to its scope and boundaries in a risk context
(Peer reviewed; Journal article, 2020-12)Bayesian analysis constitutes an important pillar for assessing and managing risk, but it also has some weaknesses and limitations. The main aims of the present paper are to summarize the scope and boundaries of Bayesian ... -
The cautionary principle in risk management: Foundation and practical use
(Peer reviewed; Journal article, 2019)The precautionary principle is well known among scientists, politicians and the public in general. However, the closely related and broader cautionary principle is not so often referred to. Whereas the precautionary principle ... -
Characterising the robustness of coupled power-law networks
(Peer reviewed; Journal article, 2019)Many networks exhibit a power-law configuration, where the number of connections each node has follows a power-law distribution, including the Internet, terrorist cells, species relationships and infrastructure. Given the ... -
Dependent infrastructure system modeling: A case study of the St. Kitts power and water distribution systems
(Peer reviewed; Journal article, 2020)Critical infrastructure systems underlie the economy, national security, and health of modern society. These infrastructures have become increasingly dependent on each other, which poses challenges when modeling these ... -
An extended method for evaluating assumptions deviations in quantitative risk assessment and its application to external flooding risk assessment of a nuclear power plant
(Peer reviewed; Journal article, 2020-04)In quantitative risk assessment, assumptions are typically made, based on best judgement, conservative, or (sometimes) optimistic judgments. Best judgment and optimistic assumptions may result in failing to meet the ... -
Feasibility study of PRA for critical infrastructure risk analysis
(Peer reviewed; Journal article, 2021)Probabilistic Risk Analysis (PRA) has been commonly used by NASA and the nuclear power industry to assess risk since the 1970s. However, PRA is not commonly used to assess risk in networked infrastructure systems such as ... -
How the distinction between general knowledge and specific knowledge can improve the foundation and practice of risk assessment and risk-informed decision-making
(Peer reviewed; Journal article, 2019)There is an increasing awareness and recognition of the importance of reflecting knowledge and lack of knowledge in relation to the understanding, assessment and management of risk. Substantial research work has been ... -
A new framework to identify and assess hidden assumptions in the background knowledge of a risk assessment
(Peer reviewed; Journal article, 2020)A risk assessment has a more or less subjective nature, as the analyst needs to make assumptions, analyse data, use models, and so on, to produce risk-related knowledge of the phenomena of interest. This background knowledge ... -
On the importance of systems thinking when using the ALARP principle for risk management
(Peer reviewed; Journal article, 2020-12)In this paper, we discuss the importance of systems thinking when using the As Low As Reasonably Practicable (ALARP) principle to support decision-making in risk management. The ALARP principle is a fundamental principle ... -
On the meaning of and relationship between dragon-kings, black swans and related concepts
(Peer reviewed; Journal article, 2021-03)Different metaphors have been introduced to reflect the occurrence of rare and surprising types of events with extreme impacts, including black swans, grey swans and dragon-kings. Despite considerable research on clarifying ... -
On the use of the vision zero principle and the ALARP principle for production loss in the oil and gas industry
(Peer reviewed; Journal article, 2019)In the oil and gas industry, there is a strong focus on reducing production loss, and in the last decade the industry has adopted Vision Zero as a governing principle, to meet this goal. A previous paper has concluded that, ... -
On the use of the ‘Return Of Safety Investments’ (ROSI) measure for decision-making in the chemical processing industry
(Peer reviewed; Journal article, 2021)Due to the high potential of chemical and process industry to damage people, as well as to cause environmental contamination, there is a need of objective criteria and methods supporting plant operators to make decisions ... -
The reliability science: Its foundation and link to risk science and other sciences
(Peer reviewed; Journal article, 2021-06)Several authors have recently questioned whether reliability is a science and a new science. The current paper follows up this discussion. It is argued that reliability is indeed a science and it is important that it is ... -
A risk science perspective on the discussion concerning Safety I, Safety II and Safety III
(Peer reviewed; Journal article, 2021-09)Recently, there has been a discussion in the safety science community concerning the validity of basic approaches to safety, referred to as Safety I, Safety II and Safety III, with Erik Hollnagel and Nancy Leveson in leading ... -
The strong power of standards in the safety and risk fields: A threat to proper developments of these fields?
(Peer reviewed; Journal article, 2019)Standards like ISO 31000 on risk management are increasingly influencing the risk and safety fields, despite rather strong criticism concerning their quality. In this paper, we perform a thorough discussion of the application ... -
Three influential risk foundation papers from the 80s and 90s: Are they still state-of-the-art?
(Peer reviewed; Journal article, 2020-01)Three of the most influential scientific works in the risk field, at least in the engineering environment, are Stan Kaplan and John Garrick's paper from 1981 on risk quantification, George Apostolakis’ paper on probability ...
