Dynamic Analysis of Energy Recovery Utilizing Thermal Storage from Batch-Wise Metal Casting
(Chapter, 2020)The thermal exergy contained in the liquid metal in ferroalloy production makes it an interesting source for energy recovery. The heat released during casting is rarely utilized today. This work investigates the feasibility ... -
Dynamic Analysis of Fire Water Pump Module
(Master thesis, 2012)The thesis starts with a simple description of the system and some brief theory needed for the following analysis. Further a factory acceptance test is performed, this implies measurement of the dynamic response due to ... -
Dynamic Analysis of Floating Bridges with Transverse Pontoons
(Master thesis, 2014)The main objective of this thesis is to analyse the dynamic response of floatingbridges with transverse pontoons, when subjected to harmonic regular waveloads. As a result, a simplified beam model of the Bergsøysundet ... -
Dynamic analysis of floating bridges.
(Master thesis, 2023)Floating bridges, also known as pontoon bridges, are structures intended to connect two sides of land separated by a body of water and differentiated from standard bridges by the use of floating elements (generally pontoons) ... -
Dynamic Analysis of Floating Dock Structures
(Master thesis, 2015)This paper concerns a dynamic analysis preformed on a floating dock structure. The structure was installed by Bi-Brygga AS and failed in 2013 during a winter storm. Bi-Brygga AS offered this structure as a case study for ... -
Dynamic Analysis of Floating Wind Turbine subjected to Deterministic Wind Gusts
(Master thesis, 2019)This thesis focuses on the time domain response under extreme deterministic wind gusts, for which simulations are carried out in order to assess the turbine’s performance and build a database: softwares SIMA, FAST and ... -
Dynamic analysis of floating wind turbines during pitch actuator fault, grid loss, and shutdown
(Journal article; Peer reviewed, 2013)Coupled non-linear aero-hydro-servo-elastic simulations of three types of floating wind turbines (spar, semi- submersible, and tension leg platform) are carried out for several fault cases over a range of environmental ... -
Dynamic Analysis of Full Scale Testing of Steel Catenary Risers using the Finite Element Method
(Master thesis, 2011)Pipes for pipelines and risers subjected to fatigue loading during deployment. Additionally, in the case of free spanning pipelines and risers the pipes may be excited at their resonance frequency by vortex induced vibration ... -
Dynamic analysis of geometrically imperfect pipes
(Master thesis, 2011)Manufactuering and installation processes for submarine pipes and risers result in geometrical imperfections. In operational conditions the pipes and risers experienced dynamic loading and fatigue failure is an issue. A ... -
Dynamic analysis of girth welded pipes
(Master thesis, 2010)Pipes for pipeline and risers are subjected to fatigue loading during deployment. Additionally, in the case of free spanning pipelines and risers may be exited at their resonance frequency by vortex induced vibration. In ... -
Dynamic analysis of material flows and embodied emissions of the building stock of a zero emission neighbourhood. Case study: Ydalir
(Master thesis, 2019)The bottom-up approach model developed earlier by Næss et al. (2018) is extended to include the dynamic material flow and embodied emissions from materials during con- struction, renovation and demolition activities of a ... -
Dynamic Analysis of Offshore Concrete Structures subjected to Earthquake
(Master thesis, 2012)This thesis attempts to study the dynamic response of offshore concrete structures by sequentially introducing physical phenomena which are related to those types of analyses. This is done by modelling a simplified part ... -
Dynamic Analysis of ROV Operation
(Master thesis, 2015)At the semi-submersible rig Snorre B, the work class remotely operated vehicle (WROV) is essential to perform drilling and production activities. Currently, the weather criterion for launching the ROV is set to four meters ... -
Dynamic Analysis of Semi-submersible Offshore Fish Farm Operated in China East Sea
(Master thesis, 2019)In recent years, the aquaculture industry in China has achieved rapid development, which covers more than half of the world aquaculture production. For further development, Chinese aquaculture companies are looking for ... -
Dynamic Analysis of the Bergsøysund Bridge in the Time Domain
