A Comparison of Hazards and Efficiencies of Conventional and Adaptive Control Algorithms Using Systems-Theoretic Process Analysis
Ohrem, Sveinung Johan; Kim, Hyungju; Lundteigen, Mary Ann; Holden, Christian (Journal article; Peer reviewed, 2019)Control systems are an important and increasingly complex part of most industrial and non-industrial systems. As such, identifying and handling associated risks is increasingly important. Systems- Theoretic Process Analysis ... -
Clarifying Implementation of Safe Design Principles in IEC 61508: Challenges of Novel Subsea Technology Development
Zikrullah, Nanda Anugrah; Kim, Hyungju; Lundteigen, Mary Ann; van der Meulen, Meine J. P. (Chapter, 2019)When new technologies are introduced to safety systems, they may raise some new discussions and clarifications about established practices. IEC 61508 represents a general framework which may apply to all electrical/ ... -
Combining system-theoretic process analysis and availability assessment: A subsea case study
Zhang, Juntao; Kim, Hyungju; Liu, Yiliu; Lundteigen, Mary Ann (Journal article; Peer reviewed, 2019)Hazard identification methods are important tools to verify that the system is able to operate according to specifications under different operating conditions. Unfortunately, many of the traditional methods are not adequate ... -
A comparison of hazard analysis methods capability for safety requirements generation
Zikrullah, Nanda Anugrah; Kim, Hyungju; van der Meulen, Meine J. P; Skofteland, Gunleiv; Lundteigen, Mary Ann (Peer reviewed; Journal article, 2021)A safety-critical system comprising several interacting and software-intensive systems must be carefully analyzed to detect whether new functional requirements are needed to ensure safety. This involves an analysis of the ... -
Maritime safety: An analysis of accident causation and measures for reducing risk at sea
Kim, Hyungju (Doctoral theses at NTNU;2016:87, Doctoral thesis, 2016)The main objective of this PhD thesis is to analyse risk reducing measures for improved safety at sea, which is detailed in five subobjectives: 1. Research objectives related to SRtP regulation 1.1 Develop analytical ... -
Prioritization Approach for Systems-Theoretic Process Analysis (PA-STPA) : Applied for Subsea Systems
Zikrullah, Nanda Anugrah (Master thesis, 2018)A Considerable amount of scenarios and constraints were produced by the basic systems-theoretic process analysis (STPA) application. It increased the difficulty to allocate resources for problem-solving. While these problems ...
