Ice Actions on Offshore Structures – With Applications of Continuous Wavelet Transforms on Ice Load Signals
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:9, Doctoral thesis, 2006)Ice actions on offshore structures are one of the main concerns for engineering activities in cold areas with ice-infested waters. This thesis deals with three aspects of ice actions, namely design ice loads from level ... -
Ice and conical structure interactions
(Master thesis, 2010)The pursuit of energy in Arctic waters drives people to design ocean structures applying new concepts.Conical structures which shift the ice failure mode from crushing to bending could reduce the total iceload. Moreover, ... -
Ice and Ice Forces in Small Steep Rivers
(Doctoral theses at NTNU;2023:431, Doctoral thesis, 2023)English summary Given the right circumstances ice can wreak havoc on riverine infrastructure. Ice runs pushing ice floes against bridge piers is frequently the governing design condition for bridges in cold regions. The ... -
Ice breakup in small Norwegian streams
(Master thesis, 2013)River ice is present parts of the year in cold region environments and is an important component of the flow regime. The river ice is known to produce many extremes and potential floods far exceed those possible under ... -
Ice drift and ice action on offshore wind farm structures
(Peer reviewed; Journal article, 2023)Development of offshore wind farms has so far been focused on areas without sea ice, but the increasing demand pushes the offshore wind industry into areas with seasonal sea ice, such as the Baltic Sea, the Great lakes and ... -
Ice intelligence retrieval by remote sensing - Possibilities and challenges in an operational setting
(Journal article; Peer reviewed, 2017)Detecting ice drift velocity when operating offshore in ice-covered waters is crucial during marine operations, as ice actions affect station keeping and ice management. Furthermore, other ice data/intelligence such as ice ... -
Ice management and design philosophy
(Chapter, 2018)Ice management (IM) is defined as all activities carried out with the objective of mitigating hazardous situations by reducing or avoiding actions from any kind of ice feature to a protected unit (e.g. a drilling vessel) ... -
Ice Management in Arctic Offshore Operations and Field Developments
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:210, Doctoral thesis, 2010)The subject ice management has been studied with the main objective to deduce a methodology that incorporates the effect of ice management on the structural reliability of offshore installations. This was done by first ... -
ICE MELTING CAPACITY OF DEICING CHEMICALS IN COLD TEMPERATURES
(Doctoral theses at NTNU;2017:258, Doctoral thesis, 2017)Cold climates cause a great number of challenges when it comes to maintaining road conditions. For instance, snowstorms, frost and ice can all create slippery and even impassible roads. Therefore, in order to ensure vehicular ... -
Ice rose diagrams for probabilistic characterization of the ice drift behavior in the Beaufort Sea
(Journal article; Peer reviewed, 2022) -
Ice thickness estimates for design of structures
(Peer reviewed; Journal article, 2023)The level ice thickness is perhaps the most important ice property in both engineering and geophysics. Ice action from level ice scales almost linearly with ice thickness and the level ice thickness gives the mode in ice ... -
Ice-Ice and Ice-Steel Friction in Field and in Laboratory
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:300, Doctoral thesis, 2013)Friction is one of the key phenomena during the interaction of ice with offshore structures and ships, ice rafting and ridging processes, and the brittle compressive failure of ice. Therefore, knowledge of the ice friction ... -
Ice-induced vibrations under continuous brittle crushing for an offshore wind turbine
(Master thesis, 2015)Offshore wind structures located in ice infested waters are subjected to actions from moving ice and forces are generated when a drifting ice crushes against the structure. The main purpose of this Master s thesis is to ... -
Identification of implementation barriers and risks at the early stage of PPP projects
(Master thesis, 2014)The main purpose of this thesis was to identify influential success and failure factors of PPP projects and to specify the potential strategies to resolve those key issues identified as important to the continued improvement ... -
Identification of quick clay using cone penetration tests and machine learning
(Master thesis, 2021)Forekomst av kvikkleire er en viktig del av geoteknisk ingeniørarbeid i Norge. Dens tilstedeværelse påvirker måten grunnundersøkelser, dimensjonering, kontroll og kvalitetssikring blir utført på i et prosjekt. Identifisering ... -

Identification of salmon population bottlenecks from low flows in a hydro-regulated river
(Journal article; Peer reviewed, 2019)Flow regime alterations from hydropower regulation may impact fish populations. Impacts can be characterized using methods for mapping bottlenecks for different species life stages. Improving the understanding of such ... -
Identification of Vibration Frequencies of Railway Bridges from Train-Mounted Sensors Using Wavelet Transformation
(Peer reviewed; Journal article, 2023)This article presents a novel methodology to extract the bridge frequencies from the vibrations recorded on train-mounted sensors. Continuous wavelet transform is used to distinguish the bridge frequencies from the other ... -
Identifisering av faktorer knyttet til kundetilfredshetsindeks (KTI) og forståelsen blant de involverte aktørene
(Master thesis, 2019)Denne masteroppgavens hensikt har vært å identifisere og vurdere faktorene knyttet til dagens kundetilfredshetsmålinger i boligprosjekter. Målingene som gjøres av Prognosesenteret, som fungerer som en bransjestandard, ... -
Identifisering av sprekker i vegflaten ved 3D laserskanning
(Master thesis, 2015)Vegnettet representerer store verdier som krever kontinuerlig overvåking og vedlikehold for å opprettholde ønsket kvalitet. Etter som vegholder ofte har begrensede ressurser er det viktig å prioritere tiltak der disse gir ...
