Safety performance monitoring of autonomous marine systems
(Journal article; Peer reviewed, 2017-03)The marine environment is vast, harsh, and challenging. Unanticipated faults and events might lead to loss of vessels, transported goods, collected scientific data, and business reputation. Hence, systems have to be in ... -
Spurious activation analysis of safety-instrumented systems
(Journal article, 2016)Safety-instrumented systems are used in industries to prevent the development of a process upset into an accident. For most processes, the desired response in the case of a process upset is to shutdown the process, and ... -
Study of testing and maintenance strategies for redundant final element in SIS with imperfect detection of degraded state
(Journal article; Peer reviewed, 2021)Safety-instrumented systems (SISs) have been widely installed to lower risks of equipment/ process by performing the designed safety functions in cases of demands. Final elements remain dormant mostly in a low demand mode ... -
Supervised Dynamic Probabilistic Risk Assessment of Complex Systems, Part 1: General Overview
(Peer reviewed; Journal article, 2021)Dynamic probabilistic risk assessment (DPRA) is a systematic and comprehensive methodology that has been used and refined over the past decades to evaluate risks associated with complex systems. However, current approaches ... -
Supervised dynamic probabilistic risk assessment of complex systems, part 2: Application to risk-informed decision making, practice and results
(Peer reviewed; Journal article, 2021)One challenge that has received attention in maritime industry is assessing the risk level of dynamic positioning (DP) systems in emergency situations. Statistics from recent years have shown that the risk level of some ... -
Supervised dynamic probabilistic risk assessment: Review and comparison of methods
(Peer reviewed; Journal article, 2022)With the adoption of autonomous systems in higher levels of autonomy, large-scale, complex and dynamic systems are becoming commonplace. Ensuring safe operation of safety-critical autonomous systems is paramount, typically ... -
The Evaluation of Fatigue as a Performance Shaping Factor in the Petro-HRA Method
(Journal article; Peer reviewed, 2018)In the development of the Petro-HRA method, a human reliability analysis (HRA) developed for the petroleum industry, a number of factors believed to effect human performance were reviewed and considered for inclusion in the ... -
The influence of interorganizational factors on offshore incidents in the Norwegian petroleum industry: Challenges and future directions
(Journal article; Peer reviewed, 2018)In the petroleum industry, incident investigations are an important means to understand and learn from undesired events. Whereas investigations in the petroleum industry typically focus on technical, human and organizational ... -
Towards supervisory risk control of autonomous ships
(Peer reviewed; Journal article, 2020)The objective of this paper is to outline a framework for online risk modelling for autonomous ships. There is a clear trend towards increased autonomy and intelligence in ships because it enables new functionality, as ... -
A value of prediction model to estimate optimal response time to threats for accident prevention
(Peer reviewed; Journal article, 2022)This paper presents a novel value of (imperfect) prediction (VoP) model to estimate optimal response time to a threat that may result in an accident. The proposed VoP model is based on information value theory and considers ...
