Q1: Please tell us about your current research.
My current research is related to the establishment of a mathematical model for ship maneuvering under windy conditions. The subject ship is the actual twin-propeller twin-rudder ferry operating in the maritime route between Sfax city and Kerkennah islands in the bay of Gabes, which is located at south-eastern part of Tunisia. It is known that strong and dominant winds are frequently blowing in this bay. The ferry operations are therefore occasionally canceled and the islanders are consequently confined in the islands. This archipelago is the birth place of my parents and I had personally experienced similar situation several times while visiting those islands. I expect that the development of computer simulation using mathematical model will help to improve the operation of the ferry in the bay of Gabes in the future. Development of the mathematical model of twin-propeller twin-rudder ship requires advanced knowledge and skills, such as estimation of hydrodynamic forces under maneuvering motion. It is a very challenging and interesting research topic for me.
Q2: Please tell us why you chose
       Osaka University
       and about your plans after graduation.
I graduated from an architectural department at the national school of architecture and town planning (ENAU) in Tunisia. That’s why I wanted to be involved with a research subject related to architecture field and that could be helpful to the society. Naval architecture and ocean engineering field seemed to me quite appropriate to pursue in this respect. Ships are complex floating structures which have many similarities with architectural concepts. However, several distinctions from dynamic point of view made this field more fascinating for me. The reason why I chose Japan for my further study is that there was no academic institutions doing research on naval architecture and ocean engineering in Tunisia . Furthermore, Japan is considered to be one of the world leading countries in this field. Tunisia is located in an important place in the Mediterranean sea from a strategic point of view so that further developments in the maritime infrastructure are highly expected. Many collaborative projects have already been set up between Tunisia and Japan. I would like therefore to actively participate in such projects in the future.
