Probabilistic Modelling of Icedrift and Ice Loading on Fixed and Floating Offshore Structures
(Doctoral theses at NTNU;2023:29, Doctoral thesis, 2023) -
Probability Study of a Crossing Collision Scenario Involving Hydrogen-Fuelled RoPax Vessels
(Master thesis, 2022)Skipsfartsnæringen er i en overgangsfase, og presset fra myndighetene om å iverksette grønne drivstoffløsninger for å redusere utslipp fra skip øker stadig. Hydrogen kommer frem som en attraktiv drivstoffkilde på grunn av ... -
Proceedings of the 4th International Workshop on Autonomous Systems Safety
(Research report, 2023) -
Proceedings of the International Workshop on Autonomous Systems Safety 2021
(Research report, 2021)The International Workshop for Autonomous System Safety (IWASS) is a joint effort by the B. John Garrick Institute for the Risk Sciences at the University of California Los Angeles (UCLA) and the Norwegian University of ... -
Process Safety and Risk Management using System Perspectives - A contribution to the chemical process and petroleum industry
(Doctoral theses at NTNU;2022:323, Doctoral thesis, 2022)Risk management is all activities used to manage the risk of hazardous events and provides information to improve decision-making. A typical approach to system safety is to identify and eliminate the causes of an accident ... -
Productivity-improving measures on steel-structures in ships and their relative effect on the CO2-emissions over a lifespan
(Master thesis, 2011)Although maritime transport are surely the most environmentally friendly way to transport , number of tones cargo shipped versus total CO2 emissions, is it great opportunities and possibilities for further improvement. A ... -
Produksjonsanlegg for rur
(Master thesis, 2019)For å utvikle et konsept for produksjon av rur er det først utviklet rammebetingelser. De er delt inn i biologiske og tekniske betingelser. De biologiske betingelsene gjør rede for rurens forhold til natur og miljø. Fjærerur, ... -
Prognosis and fault detection of drivetrains in medium-speed 10-MW Floating Wind Turbines
(Master thesis, 2020)Premature failures in large offshore Wind Turbines are often attributed to bearing failure despite gearboxes being designed and developed using the best bearing design practices. Furthermore, as turbine size and rated power ... -
Properties of breaking irregular waves over slopes
(Peer reviewed; Journal article, 2020)The present study numerically investigates the breaking and spectral characteristics and geometric properties of breaking irregular waves over slopes for different incident waves. The growth of wave non-linearity and wave ... -
Proposal and comparison of an eXogenous Kalman Filter and a Particle Filter for use with ROV thruster models
(Master thesis, 2018)Robust and accurate observer design is a prerequisite for safe and efficient underwater navigation. Especially with today's increased focus on automation and autonomy. In this thesis two model based observer designs for ... -
Propulsion control and thrust allocation on marine vessels
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:203, Doctoral thesis, 2008) -
Propulsion methods for under water snake robots - Investigation and simulation using foil for propulsion of a snake robot
(Master thesis, 2015)In this thesis we present a model of a swimming underwater snake robot. How aquatic animals move in water has fascinated people for decades. NTNU started the research on land based snake robots 11 years ago. The last years ... -
Quantifying Icebreaker Performance in Ice Management Operations by High-Fidelity Numerical Simulations
(Chapter, 2020)In the study presented in this paper, the problem of quantifying the performance of icebreaker operations within ice management (IM) has been targeted, using the capabilities of high-fidelity simulations by a discrete ... -
Quantitative Evaluation of Bathymetric LiDAR Sensors and Acquisition Approaches in Lærdal River in Norway
(Peer reviewed; Journal article, 2023)The development of bathymetric LiDAR technology has contributed significantly to both the quality and quantity of river bathymetry data. Although several bathymetric LiDAR sensors are available today, studies that evaluate ... -
Quantitative risk assessment of the performance of barriers controlling fire and explosion risk
(Master thesis, 2019)The growing population of the world places an enormous demand for energy in some form or the other. Essentially, this means that the struggle to hunt and retrieve fossil fuels has to continue for the smooth functioning of ... -
Quantitative risk modelling in the offshore petroleum industry: integration of human and organizational factors
(Journal article; Peer reviewed, 2019)In-depth investigations of major offshore accidents show that technical, human, operational and organisational risk influencing factors (RIFs) all have crucial effects on the accident sequences. Nonetheless, the current ... -
Quantitative risk modelling of maintenance work on major offshore process equipment
(Journal article; Peer reviewed, 2018)Investigations of major offshore accidents show that both technical and non-technical factors have crucial effects on the accident sequences. Nonetheless, quantitative risk analyses (QRAs) have traditionally focused on the ... -
A quantitative ship risk model to select unannounced ship inspection - A tool to improve safety and environment?
(Master thesis, 2015)Norwegian Maritime Directorate has been worked with development of the risk-based inspection. The Directorate has established a method for risk assessment at a general level. However, they do not have any concrete method ...
