The Research Project

The project involves development of novel prediction and control algorithms for parametric roll motion. The mechanism to cause parametric roll, especially the resonance phenomenon, is investigated and the parametric roll motion in head and follow sea waves is predicted by CFD modelling approach and validated by experimental data using the model scaled contained vessel of which the height of metacentre can be adjusted. Once the parametric roll motion can be predicted, a roll reduction control algorithm will be proposed and tested.


The project is going to use a combined numerical and experimental methods to analyze the collected data. As for simulations, the anti-roll systems (anti-roll tubes and stable fins) will design digital versions including 2D and 3D ones by technical software (Auto CAD, Rhino, Inventor). Hoorn vessel will be developed an intensive 3D model from the previous version which based on my design in the master course at AMC by Maxsurf and Rhino software packages. The 3D Hoorn model will be tested and measured the parametric rolling in several different head sea conditions by ANSYS Workbench software packages. In term of experiments, the project will make a real model of the anti-roll systems and will install on Hoorn model. Then, Hoorn model will be tested at the towing tank, AMC with the different head sea conditions. The data will be collected and validated between numerical and experimental outcomes.
