LNG pushbarge
(Bachelor thesis, 2016)Hensikten med oppgaven var å designe et LNG-fartøy som skal effektivisere distribusjonen av LNG. Dette LNG-fartøyet består av to deler, en pusher og en lekter. I sammenkoblet modus vil de fungere som et vanlig skip, men ... -
LNG-fuelled fishing vessels: A systems engineering approach
(Journal article; Peer reviewed, 2017)Air emissions from fishing vessels must be reduced to comply with progressively stringent environmental regulations. Among the available solutions, liquefied natural gas (LNG) fuel may represent a promising solution, ... -
Load and Deformation Relations of Placed Riprap Model with Toe Support
(Chapter, 2022)Abstract: Rockfill dams are hydraulic structures of major importance that can be exposed to extreme flood events, leading to overtopping processes. These phenomena erode and weaken their structural and geotechnical stability. ... -
Load and Response Analysis of a 10 MW SPAR Wind Turbine
(Master thesis, 2023)Teknologi basert på fornybar energi har vekket betydelig interesse, og det er viktig å fortsette forskningen og utviklingen av disse teknologiene. Overgangen til fornybar energi er i gang, med ønsket om å fase ut fossile ... -
Load and response analysis of wind turbines under atmospheric icing and controller system faults with emphasis on spar type floating wind turbine
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:192, Doctoral thesis, 2013)Deep water offshore wind is a vast, reliable and economical energy source. Floating offshore wind turbines are potential systems to capture this energy which need to be analysed and designed in order to achieve economic ... -
Load and Response Calculation from Breaking Wave Impacts on Columns of Semisubmersible Platforms
(Master thesis, 2017)Marine structures are subjected to slamming loads during their operating life. Increasing concerns are raised regarding the calculations of extreme loading caused by breaking waves. Slamming loads are associated with ... -
Load case reducation for offshore wind turbine support structure fatigue assessment by importance sampling with two-stage filtering
(Journal article; Peer reviewed, 2019)A complete fatigue assessment for operational conditions for offshore wind turbines involves simulating thousands of environmental states. For applications such as optimization, where this assessment needs to be repeated ... -
Load Charts Calculations for Offshore Pedestal Cranes by Motion Response Analysis
(Master thesis, 2014)In this Master's thesis the sea lift operation from a supply vessel onto a oil platform has been evaluated. Two models have been built and analysed with different input parameters, as well as compared with the current load ... -
Load Control for Real-time Hybrid Model Testing using Cable-Driven Parallel Robots
(Doctoral theses at NTNU;2021:284, Doctoral thesis, 2021)Real-time hybrid model testing (ReaTHM testing) is a method for emulating ocean structures that combines numerical methods with traditional hydrodynamic model testing. This is done by partitioning the ocean structure under ... -
Load Deflection Characteristics of Guide Vane End Seals
(Master thesis, 2017)This Master Thesis consider the load deflection characteristics of end seals incorporated in guide vanes used in hydropower turbines. The force response of the end seals is critical in order to prevent leakage and thus ... -
Load Distribution, from a Bridge Abutment, in a Layered EPS Embankment with different Compressive Strength: Lastspredning, under belastning av et brolandkar, i en lagdelt EPS fylling med ulik trykkstyrke
(Master thesis, 2012)The load distribution in expanded polystyrene (EPS) embankments is complex. Three different case studies were selected in order to find a simple way of estimating the stresses by depth. Three distribution theories that ... -
Load effects in reinforced concrete beam bridges affected by alkali–silica reaction—Constitutive modelling including expansion, cracking, creep and crushing
(Peer reviewed; Journal article, 2021)Material modelling, from the micro to the macro level, of concrete affected by alkali–silica reaction (ASR) has been devoted a lot of research. However, the application of the material models in structural analyses of ... -
