Real-Time Ship Draft Measurement and Optimal Estimation Using Kalman Filter
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-02)Ship operators typically depend on the visual method for draft reading, which may lead to errors or approximations, and it further introduces draft survey calculation errors and can not provide continuous updates. Ensuring accurate real-time ship draft measurement becomes crucial for enhancing navigational safety, optimizing vessel performance, and achieving precise cargo and consumable measurements. ... -
Security of Supply: A National or European Competence?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-16)Security of supply refers to governmental policies that aim to secure the availability of critical products at all times. The COVID-19 pandemic brought to fore the importance of such policies, as suddenly there was an overwhelming need for critical medical supplies that the markets were not able to fulfil. Following the pandemic, the EU has started to construct its own security of supply policy, ... -

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 ... -
Sea-spray measurement tools and technique employed in marine icing field expeditions: A critical literature review and assessment using CFD simulations
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-24)Sea-spray icing resulting from sea spray droplets accreting on exposed surfaces poses a significant safety concern for vessels and marine structures operating in cold climate regions. One of the key parameters determining the amount of ice accretion is the quantity of incoming sea spray, which eventually comes in contact with the structure in the presence of brine film freezing temperature. Hence, ... -

Coordinate Conversion and Switching Correction to Reduce Vessel Heading-Related Errors in High-Latitude Navigation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-22)Considering the distortion errors of projected coordinates and the switching property of vessel heading, coordinate conversion and switching correction methods are proposed to modify a kinematic motion model and the Unscented Kalman Filter (UKF). The coordinate conversion method utilizes the grid convergence from a Universal Transverse Mercator (UTM) projection to correct the vessel heading. The ... -

Biodiversity Impact Assessment Considering Land Use Intensities and Fragmentation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-16)Land use is a major threat to terrestrial biodiversity. Life cycle assessment is a tool that can assess such threats and thereby support environmental decision-making. Within the Global Guidance for Life Cycle Impact Assessment (GLAM) project, the Life Cycle Initiative hosted by UN Environment aims to create a life cycle impact assessment method across multiple impact categories, including ... -
Integration of renewable energy and sustainable development with strategic planning in the mining industry
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-16)With an increase in the world population, the global demand for minerals is rising, increasing energy consumption. Due to the distance of mines from urban areas, the energy required for mining is highly dependent on fossil fuels. Using renewable energies is an effective solution to reducing this problem. This study examines the challenges and opportunities of integrating renewable energy into ... -
A Meta-Perspective on Societal Security & Safety: Ontological, Epistemological, & Axiological Assumptions in Societal Security & Safety Research

The impact of safety factors on decision-making in maritime navigation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023)Approximately 85% of maritime accidents are accounted for by navigation accidents, caused by human errors such as mistakes in impropriate decision-making. Decision-making skills are the key to safe sailing. However, the assessment of decisionmaking based on objective measurements is rarely studied. This paper aims to assess the impact of safety factors on decision-making in maritime navigation. ... -
Kunnskapsoverføring i beredskapsorganisasjoner i Longyeabyen, Svalbard - En kvalitativ studie av forvaltningen av taus kunnskap i beredskapsorganisasjoner preget av høy turnover
(Master thesis; Mastergradsoppgave, 2023-07-13)Svalbard er et lite arktisk øysamfunn som betegnes som et rotasjonssamfunn. Høy turnover av ansatte i Longyearbyens beredskapsorganisasjoner har gjentatte ganger blitt fremhevet som en utfordring for erfarings- og kunnskapsoverføring (DSB, 2016), og for kontinuiteten i arbeidet med samfunnssikkerhet- og beredskap. Etter det fatale snøskredet i 2015 ble etablering av en systematikk som ivaretar ... -
