Assessment of Alternative Materials for Stiffened Panels in Ship Hulls
(Master thesis, 2025)Denne masteroppgaven undersøker mulighetene for å bruke alternative materialer til stive paneler i skipskrog, med søkelys på en sammenligning mellom NVA-stål og aluminiumlegeringen AA5083-H116. Tradisjonelt har skipsbygging ... -
Assessing the need for artificial data in offshore operability calculations
(Journal article; Peer reviewed, 2025)Offshore operations are frequently delayed by weather conditions that exceed operational limits. While such delays are expected, it is challenging to estimate them at an early point in a project. Accurate estimates are ... -
Optimal experimental design for identification of hydrodynamic loading models
(Journal article; Peer reviewed, 2024)Hydrodynamic model-scale experiments are an intrinsic part of the design of marine structures, as they enable validating and calibrating the involved hydrodynamic numerical models. Such seakeeping experiments are generally ... -
