Prediction of goldsinny wrasse (Ctenolabrus rupestris) minimum size required to avoid escape through salmon (Salmo salar) farm nets
(Peer reviewed; Journal article, 2021)The salmon (Salmo salar) aquaculture industry has used various practices to treat salmon louse (Lepeophtheirus salmonis) infections, including mechanical, thermal, and chemical treatments. However, due to the environmental ... -
Prediction of ice loads and response for an Arctic SPAR
(Master thesis, 2011)Moored floating facilities in the Arctic region can be exposed to ice loads that far exceed those of waves, wind and current. Based on previous experience it has been found that a well-working ice management system can ... -
Prediction of ice loads of an Arctic SPAR
(Master thesis, 2011)Asubstantial amount of the world’s hydrocarbon deposits is assumed to be found in the Arctic. The Arctic region differs from other regions mainly due to the climate and presence of sea ice features. In order to minimize ... -
Prediction of increased fuel consumption due to fouling of hull and propeller
(Master thesis, 2023)The escalating demand for shipping in recent decades, accompanied by the industry’s growing environmental footprint, has compelled numerous organizations and companies to explore effective decarbonization strategies. To ... -
Prediction of Load and Response of an Arctic SPAR in Ice
(Master thesis, 2010)Arctic environmental condition is extremely harsh. Shtokman field in Barents Sea is studied to conclude to the most important factors for design of offshore structures to facilitate drilling and production. In geographical ... -
Prediction of long-term extreme load effects due to wave and wind actions for cable-supported bridges with floating pylons
(Journal article; Peer reviewed, 2018)The characteristic values of the extreme environmental load effects should correspond to a specified annual probability of exceedance. These load effects can be calculated using short-term or long-term methods. The full ... -
Prediction of long-term extreme load effects due to wind for cable-supported bridges using time-domain simulations
(Journal article, 2017)Many long-span bridges that are slender and susceptible to wind-induced vibrations are currently under construction all over the world. As nonlinear structural behavior and nonlinear displacement-dependent wind loads become ... -
Prediction of Maneuverability on Double-Ended Ferry
(Master thesis, 2020)Ein balanse mellom motstand og manøvrering av eit fartøy er ei utfordring som ofte vert møtt av skipsdesignarar. Dei siste åra har merksemda rundt grøn transport og moglegheita for alternativ drivstoff endra balansen, noko ... -
