Quantitative risk modelling in the offshore petroleum industry: integration of human and organizational factors
Zhen, Xingwei; Vinnem, Jan Erik; Yang, Xue; Huang, Yi (Journal article; Peer reviewed, 2019)In-depth investigations of major offshore accidents show that technical, human, operational and organisational risk influencing factors (RIFs) all have crucial effects on the accident sequences. Nonetheless, the current ... -
Quantitative risk modelling of maintenance work on major offshore process equipment
Zhen, Xingwei; Vinnem, Jan Erik; Peng, Changyi; Huang, Yi (Journal article; Peer reviewed, 2018)Investigations of major offshore accidents show that both technical and non-technical factors have crucial effects on the accident sequences. Nonetheless, quantitative risk analyses (QRAs) have traditionally focused on the ... -
Risikostyringsverktøy for oppdrettsnæringen
Dybsland, Odin (Master thesis, 2017)RNNP (Risikonivå i Norsk Petroleumsvirksomhet) er et sikkerhetsstyringsverktøy utviklet for å vurdere risiko knyttet til storulykker i norsk olje og gassvirksomhet. Risiko knyttet til storulykker er estimert med grunnlag ... -
Risk Analysis and Modelling of Allisions between Passing Vessels and Offshore Installations
Hassel, Martin (Doctoral theses at NTNU;2017:305, Doctoral thesis, 2017) -
Risk from cyberattacks on autonomous ships
Vinnem, Jan Erik; Utne, Ingrid Bouwer (Chapter, 2018)The vulnerability of technological and administrative systems to cyberattacks has been shown to be high in several cases, which has led to different unwanted consequences. Autonomous ships will also be exposed to the threat ... -
Risk information for operational decision making in oil and gas operations
Haugen, Stein; Vinnem, Jan Erik; Brautaset, Olav; Bye, Rolf Johan; Nyheim, Ole Magnus; Seljelid, Jorunn; Wagnhild, Beate Riise (Chapter, 2015)In the oil and gas industry in Norway, there is a strong emphasis on the use of results from risk assessment as input to decision making. Quantitative Risk Analysis (QRA) is extensively used to develop safe design and ... -
Risk Model applied to Non-operational Hydrocarbon Leaks on Offshore Installations - Causal modeling of hydrocarbon leaks caused by technical degradation and design error with the use of risk-influencing factors
Kim, Suyeon (Master thesis, 2015)This project proposes a risk model for identifying causal factors of hydrocarbon (HC) leaks on offshore installations and estimating the platform-specific frequency of HC leaks. The central concern is non-operational leaks ... -
Risk Modeling of DP Operation for Offshore Tandem Offloading
Zhao, Shunan (Master thesis, 2016)The paper proposes a risk model to warn shuttle tanker drive-off previously and detect it punctually, and proposes a risk decision support model to generate, evaluate and select a best vessel maneuvering plan to avoid the ... -
Risk Reduction for Floating Offshore Installations Through Barrier Management
Vinnem, Jan Erik; Utne, Ingrid Bouwer (Chapter; Peer reviewed, 2015)Marine system accidents have a relatively high frequency worldwide. In Norwegian waters loss of installations has been avoided the last 20 years, but several near-misses and severe incidents confirm that the risk level is ... -
Risk-based decision-making support model for offshore dynamic positioning operations
Hogenboom, Sandra; Vinnem, Jan Erik; Utne, Ingrid Bouwer; Kongsvik, Trond (Journal article; Peer reviewed, 2021)A Dynamic Positioning (DP) system enables vessels and rigs to accurately maintain a predetermined position and heading or track. It enables precise operations under harsh environmental conditions. DP is used for a variety ... -
Root causes of hydrocarbon leaks on offshore petroleum installations
Vinnem, Jan Erik; Røed, Willy (Journal article; Peer reviewed, 2015)Hydrocarbon leaks on offshore installations may result in severe consequences to personnel, to the environment and to assets. In order to prevent such leaks, it is crucial to understand their root causes. The objective of ... -
Soft Causes with Hard Consequences: The role of organisational factors in the creation of structural integrity
Jens Christen, Rolfsen; Haugen, Stein; Vinnem, Jan Erik; Antonsen, Stian; Heggland, Jon Erling; Lootz, Elisabeth (Journal article; Peer reviewed, 2015)Structural integrity is usually seen as a result of design, calculations, the correct choice of materials and good engineering practice in general. In this paper, we will shed light on organisational aspects that can ... -
Supervised Dynamic Probabilistic Risk Assessment of Complex Systems, Part 1: General Overview
Parhizkar, Tarannom; Vinnem, Jan Erik; Utne, Ingrid Bouwer; Mosleh, Ali (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
Parhizkar, Tarannom; Utne, Ingrid Bouwer; Vinnem, Jan Erik; Mosleh, Ali (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 ... -
Towards an online risk model for dynamic positioning operations
Dong, Yining; Vinnem, Jan Erik; Utne, Ingrid Bouwer (Chapter, 2018)Automation and increasing complexity mean that operators have to handle data and alarms and emergent decisions under the pressure of unexpected and rapidly changing hazardous situations. Position loss during marine operations ... -
