    • Critical infrastructure resilience: A Nordic model in the making? 

      Pursiainen, Christer Henrik (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-19)
      In recent years, there has been a shift in emphasis from critical infrastructure protection to that of resilience. This development reflects the acknowledgment that complete protection can never be guaranteed, and that achieving the desired level of protection is not cost-effective as a rule in relation to the actual threats. This article reviews the responses of four of the five Nordic countries ...

    • Optimization of Pure-Component LNG Cascade Processes with Heat Integration 

      Eiksund, Oddmar; Brodal, Eivind; Jackson, Steven (Journal article; Tidsskriftartikkel, 2018-01-15)
      Liquefaction of natural gas is an energy-intensive process in which the energy efficiency depends on the number of compressors stages and the heat integration scheme. The aim of the study is to systematically evaluate process performance of pure component cascade processes, present optimized designs for all relevant numbers of compression stages and compare energy consumption between processes with ...

      Accidental oil spills can have significant effect on the coastal and marine environment. As the oil extraction and exploration activities increase in the Barents Sea, it is of increasingly importance to investigate the potential oil spill incidents associated with these activities. In this study, the transport and fate of oil after a proposed oil spill incident in Barents Sea was modelled by oil ...

    • A practical guideline for human error assessment: A causal model 

      Ayele, Yonas Zewdu; Barabadi, Abbas (Konferansebidrag; Conference object, 2017-12-12)
      To meet the availability target and reduce system downtime, effective maintenance have a great importance. However, maintenance performance is greatly affected in complex ways by human factors. Hence, to have an effective maintenance operation, these factors needs to be assessed and quantified. To avoid the inadequacies of traditional human error assessment (HEA) approaches, the application of ...

    • Dimensjonering av sikringstiltak mot tilsiktede uønskede handlinger. En kvalitativ studie av sårbarhetsvurderinger som et verktøy for dimensjonering av sikringstiltak i norske ISPS-havneanlegg 

      Korneliussen, Eirik (Master thesis; Mastergradsoppgave, 2017-12-15)
      Terror er ikke et nytt fenomen i Europa. Likevel har terrorfokuset økt som et resultat av en rekke alarmerende hendelser de siste tiårene. Etter terrorangrepene mot USA 11. september 2001 fikk den vestlige verden for alvor opp øynene for hvordan terrorangrep kan bli utført på den internasjonale arena. Som følger av terrortrusselen utviklet FNs sjøfartsorganisasjon, IMO, ISPS-koden. Koden stiller ...

    • Security and policing in Rio de Janeiro. An ethnography of the pacifying police units 

      Salem, Tomas (Master thesis; Mastergradsoppgave, 2016-12-15)
      In this thesis I address the challenges of Rio de Janeiro's ongoing public security reform, implemented through the establishment of the Pacifying Police Units (UPPs) in several of the city's favelas since 2009. I suggest that in order to address this problem, it is necessary to understand both the institutional and political context and conditions that the reform is set within, as well as the ...

      Ebbang, Christopher (Master thesis; Mastergradsoppgave, 2017-07-13)
      Denne oppgaven undersøker hvordan organisatorisk læring kan fremmes i en responsorganisasjon. Oppgaven har som utgangspunkt at læring fra erfaringer bidrar til å forklare hvordan redningsledere lærer (Sommer & Njå, 2012), og at en forståelse av individuell læring er nødvendig for å forstå hvordan organisasjoner lærer (Dixon, 1999). Sammen med en overlapp i betydningen dele og lagre erfaringer har ...

    • Finite element analysis of materials for aquaculture net cages. FEA of materials for aquaculture net cages using ANSYS Workbench 

      Myrli, Odd Einar Lockertsen (Master thesis; Mastergradsoppgave, 2017-06-20)
      The number of good sites in less exposed locations for aquaculture farming is limited. Trends are now that the fish cages are increasing in both width and depth as well as more weather-exposed locations are taken into use. As the net cages continues to increase in size, so does the material costs. The design of the sea cages should be modified for safe and reliable use in remote offshore locations. ...

    • Feasibility study of Unmanned Aerial Vehicles (UAV) application for ultrasonic Non-Destructive Testing (NDT) of Wind Turbine Rotor Blades. Preliminary experiments of handheld and UAV utrasonic testing on glass fibre laminate 

      Skaga, Simon Kleppevik (Master thesis; Mastergradsoppgave, 2017-05-31)
      In this thesis, we have conducted a feasibility study on UAV application for ultrasonic pulsed non-destructive testing of wind turbine rotor blades. Due to the high initial cost of wind turbines, and their decreasing availability due to increasing size and offshore locations, it is imperative to properly maintain these structures over their 10-30-year lifetime. Operation and maintenance costs can ...

      Denne studien skal undersøkja korleis tilsynsorgan kan bidra til sikkerheitsstyring i industriverksemder. Sikkerheitsstyring skal vera implementert på alle nivå i ein organisasjon, og prosessen skal skje kontinuerleg (Aven mfl., 2004; Stolzer mfl., 2008). Kva nivå i organisasjonen som tek avgjersler i sikkerheitsstyringsprosessen og kven som tek initiativ til oppdateringar, har vist seg å variera ...

    • Kan vi sikre oss mot flom? - En kvalitativ studie av forebyggingsarbeid i norske kommuner 

      Røsok, Mats-Fredrik Dahl (Master thesis; Mastergradsoppgave, 2017-06-01)
      I løpet av de siste årene har en erfart usedvanlig mange flombaserte hendelser i Norge. Vi kan samtidig forvente ytterligere eksponering for flombaserte hendelser i framtiden. Ulike klimaframskrivinger og prognoser viser blant annet at havnivået vil stige og ekstreme regnværsperioder vil komme oftere. I denne oppgaven har jeg undersøkt følgende problemstilling: På hvilken måte kan forebyggende arbeid ...
