Oppdrag Mjøsa - Masterplan 2025-2027
(Research report, 2025)Innlandshavet. Rolf Jacobsen fanger i et ord Mjøsas majestet. For Mjøsa er ikke bare Norges største innsjø og drikkevannskilde for titusenvis av mennesker, det er også et naturfenomen, transportåre, kilde til mat og ... -
Oppdrag Mjøsa - Nasjonal lansering på Arendalsuka 2023
(Research report, 2023)Mjøsa er Norges største innsjø og er svært viktig for mange mennesker. Den står overfor økende påvirkning som følge av utbygging, industri, jordbruk, klimaendringer med videre. Innlandet fylkeskommune, kommunene i regionen ... -
Data-driven modeling of low-frequency hydrodynamic loads
(Peer reviewed; Journal article, 2024)This paper presents a data-driven approach for estimating the linear and quadratic transfer functions relating incoming waves to hydrodynamic loads on floaters. The procedure relies on constructing a nonlinear auto-regressive ... -
Numerical analysis of slamming effects due to wave-in-deck events on offshore fish cage
(Master thesis, 2024)I denne oppgåva er det utført ein numerisk analyse av offshore akvakulturkonseptet GM Aqua Design, utvikla av Global Maritime. Målet med analysen er å evaluere effekten av støtverknader og dynamiske effektar når strukturen ... -
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 ... -
Underwater Drones as a Low-Cost, yet Powerful Tool for Underwater Archaeological Mapping: Case Studies from the Mediterranean
(Journal article; Peer reviewed, 2025)This paper investigates the transformative impact of micro-class Remote Operated Vehicles (ROVs), commonly known as underwater drones, on underwater archaeological mapping. With advancements in Unmanned Underwater Vehicles ... -
Modal Parameter Identification of Jacket-Type Offshore Wind Turbines Under Operating Conditions
(Journal article; Peer reviewed, 2024)Operational modal analysis (OMA) is essential for long-term health monitoring of offshore wind turbines (OWTs), helping identifying changes in structural dynamic characteristics. OMA has been applied under parked or idle ... -
Integrating physics-based simulations with gaussian processes for enhanced safety assessment of offshore installations
(Journal article; Peer reviewed, 2024)Installing large floating objects during offshore operations is a challenging and failure-prone task, especially when passing through the splash zone due to extreme lifting loads on the wire and the payload. For a safe ... -
