1. Rigid Body Ship Dynamics
Abstract : 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. READ MORE

2. Probabilistic Assessment of the Risk of Cargo Shifting Onboard Ships in Waves
Abstract : 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. READ MORE

3. Numerical Investigation of Ship Responses in Calm Water and Regular Head Waves
Abstract : In order to design fuel efficient ships and install right machinery onboard, ship designers need to know the interaction effects between hull, propeller and appendages in realistic operating conditions. Neglecting the interaction effects may result in under/over-prediction of the required power. READ MORE

4. Data-driven Ship Performance Models - - Emphasis on Energy Efficiency and Fatigue Safety
Abstract : Due to digitalization in the maritime industry, a huge amount of ship operation-related data has been collected. The main objective of this thesis is to exploit machine learning/big data analytics to build data-driven ship performance models, focusing on speed-power relationship modeling, and fatigue accumulation assessment during a ship’s operation at sea.

5. Numerical prediction of propeller induced hull pressure pulses and noise
Abstract : An operating marine propeller is one of the major sources inducing hull pressure pulses, onboard noise and vibration as well as underwater radiated noise. There are rising concerns of environmental impacts and comfort and welfare of passengers and crews due to these negative effects. READ MORE
