Modelling of wind turbine gear stages for Digital Twin and real-time virtual sensing using bond graphs
(Peer reviewed; Journal article, 2022)In this paper a wind turbine high-speed gear stage model is developed for the purpose of real-time virtual sensing of gear and bearing loads in a Digital Twin framework. The model requirements are: accurate representation ... -
Modelling the dynamic behaviour of a rotor nacelle assembly during the installation using a floating vessel
(Master thesis, 2020)Abstract will be available on 2023-07-01 -
Modelling, Analysis and Response-Based Operability Assessment of Offshore Wind Turbine Blade Installation with Emphasis on Impact Damages
(Doctoral theses at NTNU;2019:347, Doctoral thesis, 2019)Installing wind turbine blades is a highly demanding task due to their large lifting height and the requirements of high precision. The single blade installation method – where individual blades are lifted using a jack-up ... -
Models and Methods for Efficiency Estimation of a Marine Electric Power Grid
(Chapter; Peer reviewed, 2017)Diesel electric propulsion has become industry standard for many marine applications. Typically, a significant part of the operations of vessels with diesel electric propulsion is done with low loads on the motors and ... -
Modified Environmental Contour Method for Predicting Long-term Extreme Responses of Bottom-fixed Offshore Wind Turbines
(Journal article; Peer reviewed, 2016)Predicting extreme responses is very important in designing a bottom-fixed offshore wind turbines. The commonly used method that account for the variability of the response and the environmental conditions is the full ... -
Modified environmental contour method to determine the long-term extreme responses of a semi-submersible wind turbine
(Journal article; Peer reviewed, 2017)In this paper, the modified environmental contour method (MECM) for long-term extreme response prediction are explained and tested for the OC4 DeepCwind 5-MW semi-submersible wind turbine with the environmental conditions ... -
Modular Adaptable Ship Design for Handling Uncertainty in the Future Operating Context
(Doctoral theses at NTNU;2018:264, Doctoral thesis, 2018)A ship's value is dependent on its context as well as its design features. Ship designers therefore need to consider future operating context scenarios for designing a value-robust ship. The context of a ship comprises a ... -
Modular approach to offshore vessel design and configuration
(Master thesis, 2012)The design process used in most vessel design approaches can be described as sequential and iterative, where the initial design is subject to constant improvements. The process development is thereby constrained by the ... -
Modular Capabilities on Offshore Support Vessels
(Master thesis, 2012)The report is divided into three different categories; background, concept evaluation and comparison and the methodology development. The background gives a short introduction of product architecture, modularity and ... -
Modular Conceptual Synthesis of Low-Emission Ships
(Chapter, 2020)With the ambition of lowering emission from shipping, today’s ship designers face both the freedom and challenge to select from a large set of different ship system concepts during the conceptual design stage. In order to ... -
Modular Multi-Sensor Fusion for Underwater Localization for Autonomous ROV Operations
(Chapter, 2022)Localization filters for underwater vehicles are mostly tailored for specific sensor suites, environments, or missions. It is also well known that the underwater environment can evolve over time and throughout the mission, ... -
Modularization of Aquaculture Service Vessels - An Approach for the Implementation of Operational Flexibility
(Master thesis, 2017)The expansion of the aquaculture industry towards more exposed locations leads to uncertainties regarding the requirements for future aquaculture service vessels. These uncertainties are fueled by, among others, the lack ... -
Modularization of ship equipment in a complex vessel
(Master thesis, 2013)In early stages of design there are made big decisions under uncertainty. Ship design companies have to respond to a high number of tenders under strict time and resource-constraints in the process of selling designs. ... -
Modulbasert design av fiskefartøy
(Master thesis, 2014)Bakgrunn: De norske fiskeriene har utviklet seg fra å være nærmest et fritt fiske til en gjennomregulert næring med strenge regelkrav. Antall fiskefartøy har gått ned, men de har samtidig blitt større og mer effektive. Den ... -
Mogelegheit for batteridrift på kystgåande fiskefartøy basert på AIS-data
(Master thesis, 2018)For å redusere utslepp og stoppe økninga av den globale temperaturen, handling er nødvendig. Ein teknologi som kan erstatte forbrenningsmotoren som er brukt i dag, er batteriteknologi. Tal frå Sintef, seier at det er ein ... -
MOMEC - Mapping of Energy Consumers
(Research report, 2023)Here, we present a study of the power consumption for different vessel types, and list some of the highest loaded consumers in different operations. In this brief study we are using Electrical Power Load Analysis (EPLA) ... -
