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 two term projects to find the equilibrium position and to calculate the hydrostatic values of a floating body.
Term Project 1: Development of a program for finding the equilibrium position and plotting statistical stability curve of a barge

Term Project 2
- 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

 

3. Textbook and Reference
(1) Textbook
- Roh, Myung-Il, Ship Stability, Lecture Note for Naval Architectural Calculation, Seoul National University, Spring, 2018
(2) Reference
- 대한조선학회, “선박계산”, 텍스트북스, 2012.11
- Roh, Myung-Il, Lee, Kyu-Yeul, Computational Ship Design, Springer, 2018
- Letcher, John S., “The Principles of Naval Architecture: The Geometry of Ships”, SNAME, 2009

4. Grade Computation
Weighted system is as follows:
- Two Exams: 50%
- Term Project: 40%
- Attendance: 10%
No attendance in any exam and no submission of any term project will result in F grade.

 

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
- Late work will be not accepted.
- Show respect to others and their property.
- Come prepared to class.
- It is required to make appointments to see instructor during office hours. Send email for an appointment at least one day in advance.
- No cell phone on the desk.
