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 2 students, on a term project to calculate the hydrostatic values of a floating body, such as its volume and water plane area.
Term Project
- Development of a program for generating hydrostatic tables and plotting hydrostatic curves after calculating hydrostatic values for the given offsets table of a ship or an offshore plant

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
- All lectures, assignments, exams and term projects for this course are presented in English.
