Safety and Reliability Assessment of All-Electric Subsea
(Master thesis, 2020)Undervannsproduksjon refererer til brønner som ligger på havbunnen, og tilhørende utstyr og moduler for å produsere hydrokarboner. Det vanligste systemet for kontroll av undervannsproduksjon er et elektrohydraulisk system. ... -
Safety and reliability assessment of CO2 refrigeration system for underground applications below -50 °C
(Chapter, 2021)A new CO2 refrigeration concept is evaluated to cool the ATLAS and CMS experiments installed close to 100 m underground, at the Large Hadron Collider (LHC) at CERN. The first prototype unit produced to validate the conceptual ... -
Safety and Verification of Advanced Maritime Vessels - An Approach Based on Systems Theory
(Doctoral theses at NTNU;2018:119, Doctoral thesis, 2018)The past few decades have seen rapid technological development in ships and offshore vessels. Advanced electrical power plants and dynamic positioning (DP) systems are now widespread, and the growing demand for greener and ... -
Safety aspects of Organic Rankine Cycles (ORC) with combustible working fluid and sub-ambient condenser pressure
(Peer reviewed; Journal article, 2024)ORCs are often designed with the lower pressure limited by the ambient pressure, to avoid air leaking into the working fluid. Safely lowering this limit will be beneficial for power-production efficiency. First, cycle ... -
Safety Aspects of Organic Rankine Cycles (ORC) with Combustible Working Fluids
(Master thesis, 2021)Trass i at organiske Rankine-syklusar (ORC) har eksistert ei stund, er det lite forsking på slike syklusar der subatmosfærisk trykk blir brukt. Subatmosfærisk trykk opnar for høgare trykkforhold som igjen gjev høgare ... -
Safety barrier management: Risk‐based approach for the oil and gas sector
(Peer reviewed; Journal article, 2021)In the Oil and Gas sector, risk assessment and management have always been critical due to the possibility of significant accidents associated with the presence of large amounts of flammable hydrocarbons. Methods to provide ... -
Safety barriers against common cause failure and cascading failure: literature reviews and modeling strategies
(Chapter, 2018)Safety barriers are required in many technical systems to reduce initiating negations, suppress failure propagations, or mitigate the consequences of common cause failures and cascading failures. Based on a thorough ... -
Safety Barriers in Complex Systems with Dependent Failures: Modeling and Assessment Approaches
(Doctoral theses at NTNU;2022:40, Doctoral thesis, 2022)Technical systems are becoming more and more complex with a degree of dependencies. Such dependency issues can significantly reduce system reliability and cause catastrophes without proper prevention. Therefore, a variety ... -
Safety Barriers on Oil and Gas Platforms. Means to Prevent Hydrocarbon Releases
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:3, Doctoral thesis, 2006)The main objective of the PhD project has been to develop concepts and methods that can be used to define, illustrate, analyse, and improve safety barriers in the operational phase of offshore oil and gas production ... -
Safety Barriers: Research advances and new thoughts on theory, engineering and management
(Peer reviewed; Journal article, 2020)Safety barriers include physical and non-physical means in different industries for preventing the occurrences of hazardous events and mitigating the consequences in case they have occurred. After clarifying the relevant ... -
Safety climate as an indicator for major accident risk: Can we use safety climate as an indicator on the plant level?
(Journal article, 2016)Measuring safety climate is regarded a proactive approach to safety management. With increased focus on developing indicators for major accidents, there is a need to critically assess the effectiveness of current practices ... -
Safety Effect Assessment of Cooperative Intelligent Transport Systems - A Bowtie Analysis Approach
(Doctoral theses at NTNU;2019:380, Doctoral thesis, 2019)With the rise of intelligent transportation systems (ITS) expectations are high that they are able to further enhance road traffic safety among other transportation challenges. Cooperative intelligent transport systems ... -
Safety Effects of Horizontal Curve Design and Lane and Shoulder Width on Single Motorcycle Accidents in Norway
(Peer reviewed; Journal article, 2021)Factors related to the road infrastructure contribute to the occurrence of motorcycle accidents. This study investigates how design parameters of the existing rural two-lane road network in Norway influence the occurrence ... -
Safety effects of horizontal curve design, traffic lane and shoulder width on single motorcycle accidents in Norway
(Master thesis, 2020)Faktorer knyttet til vegens utforming og miljø har vært medvirkende i hver fjerde dødelige motorsykkelulykke. Alvorlige trafikkulykker fører til store direkte og indirekte kostnader for samfunnet og de involverte. Derfor ... -
Safety effects of traffic lane and shoulder widths on two-lane undivided rural roads: A matched case-control study from Norway
(Peer reviewed; Journal article, 2020)This study estimates the effects of lane and shoulder widths on occurrence of head-on and single-vehicle accidents on rural two-lane undivided roads in Norway while considering the differences between winter and non-winter ... -
