Numerical Study on the Dynamic Response of a Submerged Floating Tunnel Under Current Loads Based on the Segment Model Towing Test Results
(Chapter, 2020)Submerged floating tunnels (SFTs) are considered as one of the relevant concepts to replace ferry connection in the Norwegian Public Road Administration's plan to upgrade the E39 coastal highway. Current load including ... -
Numerical Study on the Effect of a Submerged Breakwater Seaward of an Existing Breakwater for Climate Change Adaption
(Chapter, 2018)In coastal areas, climate change is causing mean sea level rise and more frequent storm surge events. This means the breakwaters are expected to withstand the action of more severe incident waves and larger overtopping ... -
Numerical study on the effect of the Lüders plateau on the ductile crack growth resistance of SENT specimens
(Journal article, 2018)The increasing demand of energy prompts the petroleum industry exploitation activities to the Arctic region where the low temperature is a strong challenge, both for structural design and material selection. For structural ... -
A numerical study on the effects of DP steel microstructure on the yield locus and the stress–strain response under strain path change
(Journal article; Peer reviewed, 2023)The mechanical response of dual phase (DP) steel exhibits a complex dependence on the microstructure. The chemical composition and microstructure characteristics of the phases have significant effects on the contrast between ... -
Numerical study on the feasibility of offshore single blade installation by floating crane vessels
(Journal article; Peer reviewed, 2019)Compared with jack-up crane vessels that are now widely used in offshore wind turbine installation, floating crane vessels are more flexible with respect to working water depth and are much faster in relocation. They are ... -
Numerical study on the heading misalignment and current velocity reduction of a vessel-shaped offshore fish farm
(Peer reviewed; Journal article, 2019)Recently, the concept of a vessel-shaped fish farm was proposed for open sea applications. The fish farm comprises a vessel-shaped floater, five fish cages, and a single-point mooring system. Such a system weathervanes, ... -
Numerical study on the influence of cover thickness and rebar spacing on effective areas in reinforced concrete ties
(Master thesis, 2020)Nøyaktige estimater av rissdannelse, -fordeling, -vidde og påvirkningen dette har på konstruksjoner er essensielt for å dimensjonere for tiltenkt levetid. Formålet med denne oppgaven er å gjennomføre endelige elementanalyser ... -

Numerical study on the strain capacity of girth-welded X80 grade pipes
(Peer reviewed; Journal article, 2022)Strain capacity is an important performance indicator for designing and evaluating high-grade steel pipelines. Due to the inhomogeneity of material properties in welded structures, girth welds are one of the main factors ... -
Numerical study on the structural response of blast-loaded thin aluminium and steel plates
(Journal article; Peer reviewed, 2016)The inelastic response of thin aluminium and steel plates subjected to airblast loading is studied numerically and validated against experimental data. Special focus is placed on the influence of elastic effects and negative ... -
Numerical Study on Wave Drift Loading on Slender Marine Structures
(Master thesis, 2017)This master thesis investigates the wave drift forces acting on slender structures through numerical simulations. Basic theory is presented along with an overview of how the problem is treated in the industry and a description ... -
Numerical study towards closed fish farms in waves using two Harmonic Polynomial Cell methods
(Chapter, 2020)In order to avoid salmon lice and minimize environmental pollution, closed fish-farm concepts are gaining increasing attention in Norway. Violent sloshing of the water inside the closed cage then becomes an important issue ... -
Numerical viscosity in large time step hll-type schemes
(Journal article; Peer reviewed, 2018)We consider Large Time Step (LTS) methods, i.e., the explicit finite volume methods not limited by the Courant–Friedrichs–Lewy (CFL) condition. The original LTS method (LeVeque in SIAM J Numer Anal 22, 1985) was constructed ... -
Numerical wave tank for nonlinear waves in various water depths
(Master thesis, 2015)Numerical wave tank is always important for studying wave-body interactions. This master thesis carried out a step by step procedure to develop a nonlinear wave tank by using HPC method. The thesis work mainly focuses on ... -
