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 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-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 ... -
