(Photos: by Yiliu Liu)
- RAMS group meetings/seminars are arranged once every week, tentatively every Friday, 14:00-15:00 in VG11 (basement) at NTNU - Valgrinda.
- Most times, a paper or topic of research is presented and discussed. The main presenters are the PhD students, but also the academic staff and guests that work with RAMS.
- The seminar is open to master students, PhD students, Postdocs, academic staff and guests who are interested in the RAMS field.
- The topics and invitations are also distributed via e-mails. If you want to be on the list to present and discuss a topic we may help you with, please email: yun.zhang@ntnu.no

27.01.2017 | Prof. Anne Barros | Title: Modelling degradations, condition based maintenance and imperfect tests for Safety Instrumented System (PresentationESRELSeminarRAMS.pdf) Classical analytical models developed to quantify the availability of Safety Instrumented Systems (SIS) are currently based on the assumption of exponential lifetime distributions for all the units they are made of (1). The aim of the present work is to show how some stochastic modeling framework based on renewal processes, virtual age and multiphase Markov processes can be used to generalize existing analytical tools. The main goal is to include other lifetime laws than the exponential one (e.g. Weibull law or lifetime based on discrete state degradation process) and to model the possible effects of tests and condition-based maintenance. The presentation this Friday will focus on a preliminary discussion about Weibull law versus Exponential law. (1) M. Rausand, Reliability of Safety Critical Systems, Wiley, Hoboken, NJ. 2014 |

04.03.2016 | Hyung-Ju Kim | Presentation of journal paper submitted for review. "Enhanced Barrier Management by Learning from Accident Causation Theories" Abstract Several accident causation theories have been developed to identify why major accidents occur and to prevent them from occurring (see e.g., Rosness et al., 2010). The objective of this article is to investigate relations among the theories and suggest an enhanced barrier management process utilising the learnings from each accident causation theory. By utilising the accident causation theories and the barrier and operational risk analysis (BORA) as a basis, this article suggests two additional stages to the barrier management process and six additional risk influencing factors (RIFs) in the barrier analysis, which can enhance barrier management process. The enhanced barrier management process may facilitate effective and efficient control of risks which can lead to major accidents, and thereby it may contribute to preventing major accidents in many different industries where barriers play an important role for controlling risks. |
18.03.2016 | Geir-Ove Strand | Human factors in offshore drilling operations Revisit of presentation on subject from late 2014. Finally, after years struggle navigating through many human factor domains we've managed to hopefully make a decent version that now has been submitted for puplication.
Abstract The main principle for risk control during offshore well activities is to always maintain two independent and tested well barriers towards any potential source of inflow. The short lifespan and dynamic nature of well drilling operations makes this a challenge. Experiences from several industry accidents the last decade reveal that two well barriers were not properly maintained by the drilling crew during the operation, and thus that well safety was compromised. Probabilistic risk assessments are viewed as key in managing risk of low probability and high consequence activities. The purpose of this paper is to identify and discuss performance influencing factors relevant to performing well probabilistic risk assessments. In this paper we revisit four historic well accidents in the last decade based on the statements made by drilling personnel that the human-machine interface is vital in providing the drilling crew with a necessary understanding of in-situ wellbore flowrates and pressures. Monitoring the flowrates and pressures in the well are the most important factors in well control from a well energy containment perspective. Three out of the accidents appeared in support for the importance of monitoring in-situ flowrates and pressures to maintain well control. However, one accident occurred in spite of state of the art technology for wellbore pressure- and flowrate monitoring. This blowout can to a larger extent be explained as a violation that stem from an over-confidence emerging from use of this new technology. The over-confidence allowed for breaching the safe envelope of best drilling practises. |
01.04.2016 | Prof. Antoine Rauzy | Course on Systems Engineering (discussion) Antoine would like to present a course on Systems Engineering he created for Ecole Centrale Paris. The course is an introduction to Systems Engineering, or more exactly to Systems Modelling. It is delivered to the whole promotion of first year students (which corresponds to third year of the university), i.e. 500 students, on the flipped classroom principle. This seminar aims at launching a discussion on what could be done at NTNU in this direction. |

He received his Ph.D. in Systems Optimisation and Dependability in 2008 from Troyes University of Technology (France) where he held an assistant professor position from 2009 to 2011. His research interests include stochastic modelling for the evaluation/prediction of key performance indicators (reliability, energy efficiency, …), maintenance optimization (condition-based maintenance, prognostics-based maintenance decision-making, opportunistic and dynamic grouping maintenance), reliability importance measures and their related applications. Phuc Do supervised 4 pre-doctoral thesis and 4 PhD candidates. He has published 13 journal articles in journals (Reliability Engineering & System Safety, IEEE Transactions on Reliability, European Journal of Operational Research; Journal of Risk and Reliability, etc) and over 30 conference articles in international conferences.
