Asset Management of Existing Concrete Bridges Using Digital Twins and BIM: a State-of-the-Art Literature Review
(Peer reviewed; Journal article, 2022)The need to optimize investments in bridge maintenance has created a demand for improved bridge management systems (BMS). Outdated practices in bridge inspection and constant advances in information technology have also ... -
Biotransformation of chemically dispersed diesel at sub-zero temperatures using artificial brines
(Peer reviewed; Journal article, 2020)The biotransformation of hydrocarbon compounds in seawater at sub-zero temperature has gained research interest in recent years with the most focus placed on temperatures around 0°C. In this study, biotransformation of ... -
Corrosion-free concrete structures by the use of FRP (Fibre reinforced Polymers)
(Chapter, 2022)Fibre reinforced polymers may be suggested as a solution to one of the major durability problems with reinforced concrete; the corrosion of the internal steel reinforcement. The durability of fibre reinforced polymers, ... -
Crude oil migration in sea-ice: Laboratory studies of constraints on oil mobilization and seasonal evolution
(Journal article; Peer reviewed, 2019)Rising Arctic maritime activities and hydrocarbon development increase the risk of an oil spill in and under Arctic sea-ice. Oil spilled under growing sea ice would be encapsulated within the ice cover. During spring and ... -
Examination of ice reports from vessel traffic along the Norwegian coastline, 2014-2022
(Peer reviewed; Journal article, 2023)The Norwegian Coastal Administration provides information on ice conditions for vessels traveling in Norwegian waters primarily from the Swedish border to Kristiansand as well as Kirkenes, a port located in the far north ... -
Freeze-thaw damage evaluation and model creation for concrete exposed to freeze–thaw cycles at early-age
(Peer reviewed; Journal article, 2021)Concrete subjected to freeze–thaw cycles action at early-age will suffer serious physical damage, resulting in degradation of the concrete’s performance. The subsequent curing conditions after early-age freeze–thaw cycles ... -
From above and standing atop- two views of Norwegian fjord ice

Generalized Chessboard Structures Whose Effective Conductivities Are Integer Valued
(Journal article; Peer reviewed, 2012)We consider generalized chessboard structures where the local conductivity takes two values 𝑎� and 𝑏�. All integer combinations of 𝑎� and 𝑏� which make the components of effective conductivity matrix integer valued are ... -
Hvordan håndteres avrenning fra ferskfisktransport i andre fiskenasjoner, en komparativ studie av Irland, Island og Færøyene
(Nofima rapportserie, Research report, 2022)Det ble gjennomført en komparativ studie hos villfiskforedlere, lakseslakteri, transportbyrå og tilsynsmyndigheter i Irland, Island og Færøyene der man diskuterte problemstillingen rundt avrenning fra lastebiler som ... -
Ice Conditions in Beisfjord, Norway from 2021–2023
(Peer reviewed; Journal article, 2023)Since 2017, observations of ice conditions have been made in the northern Norwegian fjord, Beisfjord, to better understand the mechanisms of ice formation and variability in ice thickness, crystallography, and properties ... -
Ice conditions in northern Norwegian fjords: Observations and measurements from three winter seasons, 2017–2020
(Peer reviewed; Journal article, 2022)Freshwater provided by rivers beginning deep within the mountains, feeds into fjords along the coast of Norway, often forming a brackish surface layer that will change in its salinity, thickness, and extent throughout the ... -

(Peer reviewed; Journal article, 2022)Freshwater provided by rivers beginning deep within the mountains, feeds into fjords along the coast of Norway, often forming a brackish surface layer that will change in its salinity, thickness, and extent throughout the ... -
Ice extent in sub-arctic fjords and coastal areas from 2001 to 2019 analyzed from MODIS imagery
(Peer reviewed; Journal article, 2020)Results examining variations in the ice extent along the Norwegian coastline based on the analysis of Moderate Resolution Imaging Spectroradiometer (MODIS) images from 2001 to 2019,February through May, are presented. A ... -
Ice Formation in Norwegian Fjords – Findings from the 2018 - 2019 Field Season
(Chapter, 2020)Understanding ice conditions in fjords is imperative to ensure safe operations and to protect the surrounding environment. Seven fjords in northern Norway were visited in March 2019, six with significant ice cover. In each ... -
Ice load measurements on Rätan concrete dam using different sensor types
(Peer reviewed; Journal article, 2021)Concrete dams in cold regions are designed to withstand loads from the ice sheet on top of the reservoir.However, the ice load's magnitude and return period are among the most considerable uncertainties in safety assessments ... -
Influence of concrete’s mechanical properties on the cracking of concrete dams
(Chapter, 2021)Analytical methods of structural stability assessment of concrete dams are often too simple and thus conservative in their predictions.Without the actual foundation geometry, capacity for some rigid body failure modes are ... -
Influence of large-scale asperities on the shear strength of concrete-rock interface of small buttress dams
(Peer reviewed; Journal article, 2021)This paper presents an investigation of the influence of large-scale asperities on the shear strength of four physical models of a pillar (also known as buttress web)from Kalhovd dam in Norway. The objective was to observe ... -
Influence of large-scale asperities on the stability of concrete dams
(Chapter, 2022)For concrete dams founded on rock, there are only a few options in the common analysis methods to account for large‐scale asperities. However, previous research alludes that they have a significant impact on the behaviour ... -
Influence of location of large-scale asperity on shear strength of concrete-rock interface under eccentric load
(Journal article, 2020)The location and geometry of large-scale asperity present at the foundation of concrete gravity dams and buttress dams affect the shear resistance of the concrete-rock interface. However, the parameters describing the ...
