1. Rigid Body Ship Dynamics
Sammanfattning : It is common today that operational data is recorded onboard ships within the Internet of Ships (IoS) paradigm. This enables the possibility to build ship digital twins as digital copies of the real ships. Predicting the ship’s motions with ship dynamics could be an important sub-component of these ship digital twins. LÄS MER
2. Time Simulation of the Behaviour of Damaged Ships in Waves
Sammanfattning : The cause of event and ability for ship survival after damage are in many cases poorly described by pure static considerations. The dynamic properties of the ship and environment will be significant in the assessment of the damage scenario. Physical theories describing these properties have been developed since many decades.

3. Dynamics of Vehicle-Deck Interactions
Sammanfattning : The work presented in this thesis concerns the modelling and analysis of vehicle-ship deck interactions. The physical modelling of vehicles is discussed together with the modelling of supporting structures/ship decks, and the interactions between vehicles and supporting structures. LÄS MER
4. Probabilistic Assessment of the Risk of Cargo Shifting Onboard Ships in Waves
Sammanfattning : This thesis is the result of work within the research project "Probabilistic Models for Ship Safety in Rough Seas". One major danger in sea transportation is the shifting of cargo. The aim of the project has been to develop a methodology for assessing the risk of cargo shifting as well as performing some case studies. LÄS MER
5. Indirect System Identification for Unknown Input Problems : With Applications to Ships
Sammanfattning : System identification is used in engineering sciences to build mathematical models from data. A common issue in system identification problems is that the true inputs to the system are not fully known. In this thesis, existing approaches to unknown input problems are classified and some of their properties are analyzed. LÄS MER
