About 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.

Purposes and Targets: The primary purpose of the research project is to study the parametric rolling which occurs on the model scaled container vessel when she sails in head and follow seas. Besides, application of two methods: anti-roll tubes and stable fins on the model vessel in order to minimize the parametric rolling response for the model container vessel.

The research would like to focus on the main objectives are as follows:

  1. Evaluation and analysis of parametric rolling of the scale model container vessel;
  2. Design anti-rolling systems for the model scaled container vessel (Digital design version and reality model);
  3. Application of two study solutions of parametric rolling reduction (Anti-roll tubes and stable fins);
  4. Analysis of the parametric rolling of the container vessel by a numerical method (CFD and MATLAB/Simulink);
  5. Analysis of the parametric rolling of the container vessel by an experimental method (Model testing at the towing tank);
  6. Comparison and validation between numerical and experimental outcomes; and
  7. Draw a conclusion of the applied solutions to the parametric rolling reduction.
