Application of a structured decision-making process in cryospheric hazard planning: Case study of Bering Glacier surges on local state planning in Alaska
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-28)Surging glaciers are glaciers that experience rapidly accelerated glacier flow over a comparatively short period of time. Though relatively rare worldwide, Alaska is home to the largest number of surge-type glaciers globally. However, their impact on the broader socioecological system in the state is both poorly understood and underresearched, which poses a challenge in developing appropriate ... -

The application of unmanned aerial vehicles for snow avalanche search and rescue
(Master thesis; Mastergradsoppgave, 2016-06-01)Snow avalanches claim in excess of 200 lives annually on a worldwide basis. However, since the invention of the first effective avalanche transceiver, the process of locating victims has remained fundamentally unchanged. Humans as a carrier for locating devices are perceived to be inefficient when moving over rugged avalanche debris, and potentially exposed to excessive risk from secondary avalanches. ... -

What is the message to the Arctic and Africa respectively? The article concludes that China’s regional strategies aptly ... -
Arctic Heritage at Risk: Insights into How Remote Sensing, Robotics and Simulation Can Improve Risk Analysis and Enhance Safety
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-23)Increased and enhanced utilisation of remote sensing and robotics in the Arctic can further enhance cultural safety and well-being and reduce the risks posed to archaeologists, heritage workers and others in the field. In this preliminary scoping survey, the authors review the current use of these technologies and consider a range of related issues, from cultural safety to nefarious use by criminals. ... -
Arctic region as a new hydrocarbon production area. Technology needs and equipment availability for the development of the Russian Arctic
(Master thesis; Mastergradsoppgave, 2021-05-16)In this thesis, a number of questions, concerning the present and the future of Russian hydrocarbon policy in the Arctic area are covered, with a description of necessary technologies and main projects that constitute Russian plans for the nearest decade up to 2030 in presence of western technological and financial sanctions, available equipment and potential for localization. The main contribution ... -
Assessing probabilistic modelling for wind speed from numerical weather prediction model and observation in the Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-07)Mapping Arctic renewable energy resources, particularly wind, is important to ensure the transition into renewable energy in this environmentally vulnerable region. The statistical characterisation of wind is critical for effectively assessing energy potential and planning wind park sites and is, therefore, an important input for wind power policymaking. In this article, different probability density ... -
Assessing resilience in mechanical systems: an industrial perspective
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-03-12)Purpose - Resilience as a novel concept has attracted the most attention in the management of engineering systems. The main goal of engineering systems is production assurance and increasing customer satisfaction which depends on the suitable performance of mechanical equipment. “A resilient system is defined as a system that is resistant to disruption and failures and can recover itself and returns ... -

Assessing the impact of the securitization narrative on climate change adaptation in Nigeria
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-01)In Nigeria, the threat posed by climate change is leading policymakers and the media to frame climate change as a security threat that warrants support for adaptive actions. We draw upon securitization theory to examine how security narratives affect climate change adaptation. Using primary and secondary data, we find that although securitization arguments are easily identified in climate change ... -
Assessing the Risk of Escape from Marine Fish Farms. Improving Data Collection Strategies and Development of Risk Indicators
(Master thesis; Mastergradsoppgave, 2016-05-31)Marine fish farming is one of Norway’s largest industries and exports. The industry is in rapid development and secures employment for several thousand people, all along the Norwegian coastline. Fish farming is regarded as a relative sustainable method for food production. However, the industry is still prone to certain challenges and problems. Escape of fish, for instance, is one of the industry’s ... -
Assessment of the impacts of landscape patterns on water quality in Trondheim rivers and Fjord, Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-29)Due to the impacts of hydrological and ecological processes on water quality, discharges from upstream catchments have induced significant pollution to the recipients. This study aims to investigate the possible pollution sources from catchments with different types of land use and landscape patterns and develop the relationships between water quality and the catchment hydro-geological and ... -
Auditing Industrial Safety Management: A Case Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019)As industries are becoming increasingly self-regulatory, external auditing has become increasingly important to ensure that industrial practices are in line with regulations and the public good. This study asks if there is a fit between the industrial practices of safety management and external auditing. It concludes that while companies largely manage safety through operational-level experience and ... -
Availability assessment of oil and gas processing plants operating under dynamic Arctic weather conditions
(Peer reviewed; Journal article; Tidsskriftsartikkel, 2016-03-19)We consider the assessment of the availability of oil and gas processing facilities operating under Arctic conditions. The novelty of the work lies in modelling the time-dependent effects of environmental conditions on the components failure and repair rates. This is done by introducing weather-dependent multiplicative factors, which can be estimated by expert judgements given the scarce data available ... -
Availability Importance Measure for Various Operation Condition
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-01)The concept of availability importance measures can be used to identifying critical components from the availability performance point of view. The availability of an item depends on the combined aspects of its reliability and maintainability performance indices. These indices are considerably affected by operational and environmental conditions such as; ambient temperature, precipitation, wind, ... -

(Master thesis; Mastergradsoppgave, 2021-06-27)Endinger i verdensstrukturen har bidratt til utvikling av den tradisjonelle sikkerhetsrealiteten, mot mer komplekse og sammensatte systemer. Disse kompleksiteter har ført til dannelsen av nye risikoer og handlingsmønstre i håndteringen av radikalisering og voldelig ekstremisme. Denne studien handler om utfordringer som er tilfellet på ulike nivåer av det etablerte forebyggingssystemet. Oppgaven ser ... -
Barrier management - Influence from the human factor in the arctic
(Master thesis; Mastergradsoppgave, 2013-05-31)In recent years several serious near-misses with major hazard accident potential have happened on the Norwegian Continental Shelf, many of them hydrocarbon leaks. Research has shown that many of these are caused by manual intervention. Despite this fact, current focus in QRAs and have been for a long time, are on technical systems. This is despite recent trends showing no decline in risk level. A ... -
