Modelling of Metocean Conditions for the Purpose of Planning Marine Operations
(Master thesis, 2015)The sea conditions of two areas, Haltenbanken and the Barents Sea, have been established in this project. Furthermore, a few cases of marine operations have been evaluated, among other topics. The fist part establishes ... -
Modelling of Modular Multilevel Converters for Fast and Accurate Simulation of Electromagnetic Transient Phenomena in HVDC Applications
(Master thesis, 2016)Modular multilevel converters (MMC) are gradually becoming the technology of choice in high-voltage direct current (HVDC) power transmission for grid integration of large-scale offshore wind farms and multi-terminal HVDC ... -
Modelling of multimode and layer structure by transfermatrices
(Master thesis, 2010)Modelling of multimode and layer structure by transfermatrices -
Modelling of Multistream LNG Heat Exchangers
(Master thesis, 2011)The main goal of this thesis is to find out if a liquefied natural gas multistream heat exchanger numerical model is achievable. This should include several features usually neglected in nowadays available heat exchanger ... -
Modelling of oil thickness in the presence of an ice edge
(Peer reviewed; Journal article, 2020)Oil slick thickness is a key parameter for the behaviour of oil spilled at sea. It influences evaporation and entrainment, viable response options, and the risk to marine life at the surface. Determining this value is ... -
Modelling of PA in inner liner in flexible pipes
(Master thesis, 2017)In this report, the mechanical behavior of the semi-crystalline thermoplastic, polyamide 11, has been investigated. The material is commonly used in flexible pipes to ensure safe transportation of oil and gas offshore. The ... -
Modelling of Paraffin Wax in Oil Pipelines
(Master thesis, 2012)As warm oil or condensate from the reservoir flow through a pipeline on the cold sea bottom, wax often precipitate and deposit on the wall. To predict the rate of the deposition, wax modeling is important. The main mechanism ... -
Modelling of Pedestrian Loading on Slender Footbridges
(Master thesis, 2015)This thesis concerns itself with the dynamic response of a slender network arch bridge by means of a numerical model. The numerical model is generated using a Python code written by Ph.D. Candidate Anna Ostrycharczyk. The ... -
Modelling of Photovoltaic Modules with Battery Energy Storage in Simulink/Matlab: With in-situ measurement comparisons
(Master thesis, 2014)The use of renewable energy sources is increasing and will play an important role in the future power systems. The unpredictable and fluctuating nature of solar power leads to a need for energy storage as the prevalence ... -
Modelling of Processes in Solar-Grade Silicon Production
(Master thesis, 2008)As the solar cell market is continuing to grow, the opportunities for silicon producers specifically targeting a product quality adjusted to solar cell applications have increased. To improve the possibilities for automatic ... -
Modelling of reacting multi-phase flow for biomass gasification
(Doctoral theses at NTNU;2020:103, Doctoral thesis, 2020)Entrained flow gasification of pulverized biomass is considered as one of the potential technology routes to produce syngas, which later can be used to produce second generation of biofuels via Fisher-Tropsch (FT) synthesis. ... -
Modelling of Ringing Loads on Offshore Wind Turbine Monopiles
(Master thesis, 2020)Ringing er et fenomen som kan true den strukturelle integriteten til offshore vindturbin-monopeler. Det er karakterisert som en plutselig transient oscillering ved bølgefrekvens høyere enn egenfrekvensen til strukturen, ... -
Modelling of Rotating Turbulent Flows: Computer simulation of turbulent backward-facing step flow with system rotation
(Master thesis, 2011)An investigation of how different levels of turbulence modelling tackle the effects of system rotation has been performed. Ranging from simple one-equation models to large-eddy simulations, different approaches have been ... -
Modelling of Semi-Competing Risks Using the Illness-Death Model with Shared Frailty
(Master thesis, 2016)Semi-competing risks are a variation of competing risks where a terminal event censors a non-terminal event, but not vice versa. This thesis describes and studies modelling of semi-competing risks using the illness-death ... -
Modelling of Ship Superstructure Icing: Application to Ice Bridge Simulators
(Master thesis, 2012)Increasing activities on high north regions bring about a demand of safety ship navigation. Under severe weather condition considerable amounts of ice may accumulate on marine structures. Ice bridge simulator is of importance ... -
Modelling of skirted foundations for offshore wind turbines
(Doctoral theses at NTNU;2018:140, Doctoral thesis, 2018)The thesis focuses on the modelling of the response of shallow skirted foundations supporting offshore wind turbines (OWT). OWT-structures need to be optimized in design to reduce the cost of energy from offshore wind ... -
Modelling of soil-structure-interaction for flexible caissons for offshore wind turbines
(Journal article; Peer reviewed, 2018)Published foundation models and procedures for calculation of caisson foundation response typically assume a rigid caisson in deformable soil. However, recent published measurement data from a prototype suction bucket ... -
