2. Course Topics and Description
The course deals with ‘Ship Stability’ in ocean environment
1) Based on the fluid mechanics, position, and orientation of a ship in calm water such as immersion, heel, and trim are introduced.
2) Then the students learn how to evaluate the required intact and damage stability of IMO regulations.
3) Also students have to work in team, consisting of 3 students, on a term project to calculate the properties of a floating body, such as its volume and water plane area. The floating body can have various types of complex bodies – e.g., barge type or semi-submersible type. Therefore, a polyhedron that is a solid bounded by planar faces, for which triangle meshes are commonly used, is generated by discretizing the surface model of the hull form. The surface area, volume, moment, and moment of inertia of the surface model, which is generally used to calculate the hydrostatic properties, can be calculated from the polyhedron.
Term Project

- Programming for the calculation of hydrostatic properties such as displacement volume, KB, LCB, BMT, BML, water plane area, LCF, wetted surface area for a ship or an offshore structure

4. Grade Computation
Weighted system is as follows:
- Two Exams: 60%
- Term Project: 30%
- Attendance: 10%
In case of an excused absence, the student must make-up any missed test, quiz or homework the following day during a free period, before or after school. Unexcused absences will result in a zero.

 

5. Website: http://etl.snu.ac.kr
Most assignments and instructions will be made only on the website, so check it frequently.

 

6. Class Expectation
