Uncertainties in current measurements in the northern North Sea
(Journal article; Peer reviewed, 2017)A met–ocean measurement program of waves and current profiles at five locations in the northern North Sea was performed over a period of approximately 5 years. Despite quality control, the measured current speed data ... -
Uncertainties In Predicted Extreme Wave Induced Platform Response
(Master thesis, 2014)Before the long term response prediction is performed, a generic response function is firstly introduced. The generic response function is given as a function of weather characteristics in terms of hs and tp, and the shape ... -
Uncertainties in scheduling and execution of trackwork in Sweden
(Peer reviewed; Journal article, 2023)Trackwork planning and scheduling are demanding because they require strategic foresight and must be completed well in advance. In Sweden, trackwork is performed by maintenance contracting companies during an operation ... -
Uncertainties in the Design of Monopile Offshore Wind Turbines
(Doctoral theses at NTNU;2023:276, Doctoral thesis, 2023)English summary If the ambitious targets for growth in installed capacity of offshore wind turbines over the next decades are to be met, more cost-efficient wind farms need to be developed. One way of achieving this can ... -
Uncertainties of Ship Speed Loss Evaluation Under Real Weather Conditions
(Chapter, 2018)A correct assessment of the ship speed loss in conditions of exploitation is becoming increasingly important for ship owners as well as ship designers. We are witnessing the increasing concern for the environment and ... -
Uncertainty Analyses of Time in Construction Projects
(Master thesis, 2017)The aim of this master thesis is to investigate how uncertainty analysis on time can contribute to a better foundation for decision-making in the project planning phase, and by this reduce the total time spent in this ... -
Uncertainty Analysis and Quantification in Olympus Synthetic Reservoir Model
(Master thesis, 2023)Denne studien tilbyr en analyse av usikkerheten knyttet til bunnhullstrykk (BHP) utført på det kunstige Olympus-reservoarmodellen. Forskjellige BHP-scenarier ble tatt i betraktning ved bruk av ulike reservoarrealiseringer. ... -
Uncertainty Analysis for Assessing Leakage Through Water Tunnels: A Case from Nepal Himalaya
(Journal article; Peer reviewed, 2010)Water leakage problems in unlined or shotcrete lined water tunnels are not new issues. In many occasions severe water leakage problems have been faced that not only have reduced the stability of the rock mass, but also ... -
Uncertainty analysis for assessing rock mass quality and water inflow in hard rock subsea tunnels
(Chapter, 2009)In many occasions considerable discrepancies have been found between predicted and actual rock mass conditions, resulting significant cost and time overrun. Finding innovative solutions for quantifying geological uncertainties ... -
Uncertainty analysis in a large-scale water quality integrated catchment modelling study
(Journal article; Peer reviewed, 2019)Receiving water quality simulation in highly urbanised areas requires the integration of several processes occurring at different space-time scales. These integrated catchment models deliver results with a significant ... -
Uncertainty analysis of the hydrodynamic coefficients estimation of a nonlinear manoeuvring model based on planar motion mechanism tests
(Journal article; Peer reviewed, 2019)Uncertainty analysis of the identified hydrodynamic coefficients of a nonlinear manoeuvring model is presented in this paper. The classical parameter estimation method, Least Square, is briefly introduced, and the uncertainty ... -
Uncertainty analysis of tunnel squeezing for two tunnel cases from Nepal Himalaya
(Journal article; Peer reviewed, 2007)Weak rocks such as shale, slate, phyllite and schist, and the rock mass of weakness/fault zones are incapable of sustaining high tangential stress. Severe tunnel squeezing is therefore common in the tectonically active ... -
Uncertainty and risk assessment of leakage in water tunnels - a case from Nepal Himalaya
(Proceedings: World Tunnel Congress 2008;, Research report, 2008)Safety and stability are the key issues in underground excavations. Making tunnels water tight plays an important role in this regards. Water leakage problems in unlined or shotcrete lined water tunnels are not new issues. ... -
Uncertainty and sensitivity analysis for the performance evaluation of ship dynamical model
(Chapter, 2022)Model uncertainty is pervasive and inherent in the engineering field. It could bring potential risks in real applications, especially for ship behaviour prediction under environmental disturbances. The evaluation and ... -
Uncertainty Assessment of Wave Loads and Ultimate Strength of Tankers and Bulk Carriers in a Reliability Framework
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:143, Doctoral thesis, 2010)The main aim of the research work in this thesis is to investigate the uncertainty of wave-induced loads and ultimate strength of tankers and bulk carriers in a reliability framework. The ship structure is generally designed ... -
Uncertainty assessment of wave- and current-induced global response of floating bridges - A numerical investigation
(Doctoral theses at NTNU;2020:126, Doctoral thesis, 2020)Floating pontoon bridge concepts have proven to be useful for crossing very deep and wide waters where conventional bridge types are not feasible, and different concepts have been built in several locations around the world ... -
Uncertainty assessments of structural loading due to frst year ice based on the ISO standard by using Monte-Carlo simulation
(Peer reviewed; Journal article, 2020)Sea ice is the major source of loading for structural design in cold regions. The intrinsic properties of sea ice are generally associated with high degrees of uncertainty due to ice growth taking place during different ... -
