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 formation and growth in supercooled water–alcohol mixtures: Theory and experiments with dual fiber sensors
(Peer reviewed; Journal article, 2020)Increased knowledge on fluid-solid phase transitions is needed, both when they are undesired and can impair processes operation, and when strict control is required in fields such as food technology, the pharmaceutical ... -
Ice growth and decay on road cuts along Bynesveien in Trondheim
(Master thesis, 2020)Dannelse-, smelte- og nedfallsprosessene til en iskjøving langs fylkesvei 715 i Trøndelag i Norge ble kartlagt gjennom vinteren 2019/2020, med det formål å undersøke påvirkningen av luft- og bergtemperatur på endringer i ... -
Ice induced resistance of ship hulls: A comparison of resistance estimated from measurements and analytical formulations
(Master thesis, 2011)Due to global warming and hydrocarbon exploration in the Arctic areas, there is an increasing maritime activity in ice infested waters. Today one can with good accuracy predict if a vessel will be able to survive an encounter ... -
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 Load Impact on the Power Train of Azimuth Propulsion Systems
(Master thesis, 2014)This thesis seeks to investigate the advantages of using multibody simulation to develop proper models for power train analyses of azimuth propulsion systems. Azimuth thrusters are commonly installed on ice classed offshore ... -
Ice loading on Semi-Submersible: Local Analysis of Structural Response
(Master thesis, 2019)Interessen for Arktis ha vært økende de siste årene, og en økning i aktivitet i denne regionen en setettersom søken etter olje og gass fortsetter. Nye utfordinger oppstår siden miljøet i disse områdene er tøffe og ... -
Ice Loading On Ship Hull - Ice Specimen Testing and Stress Analysis of Local Plate Fields in the Bow Region.
(Master thesis, 2017)Arctic operations are mostly carried out in seas covered in ice. For these operations, both DNV GL and IACS provide regulations for classification of ships. Interaction with ice is difficult to determine, as it could occur ... -
Ice Loading on Ship Hulls

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 Management with System Theoretic Process Analysis (STPA) for Marine Operations in Arctic Environments
(Master thesis, 2019)Det siste hundreåret har Arktis vore forlokkande for modige forskarar og eventyrarar, men utilgjengeleg for dei fleste. Klimaendringar og framsteg i teknologi endrar dette raskt, noko som gjer den arktiske regionen meir ... -
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 particles sink below the water surface due to a balance of salt, van der Waals and buoyancy forces
(Journal article; Peer reviewed, 2018)According to the classical Archimedes’ principle, ice floats in water and has a fraction of its volume above the water surface. However, for very small ice particles, other competing forces such as van der Waals forces due ... -
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 Loading on Ship Hull During Ramming
(Master thesis, 2012)As a result of the steadily increasing activities related to marine technology in Arctic regions, Det Norske Veritas has launched an ice load monitoring project to gather knowledge of the ice conditions and prevailing ... -
Ice-Induced Loads on Ship Hulls
(Master thesis, 2012)The calculation of ice-induced loads on ships is still mainly based on empirical models. In order to gain a better physical understanding of the loading on ice-going vessels, Det Norske Veritas launched an ice load monitoring ... -
