Study Guide

Objective

The student is able to calculate the floating position and the initial stability of a ship, both manually and with a computer program. The student is able to avoid the dangers related to floatability and stability in her/his design work. The student can analyze stability- related problems, such as why the Vasa, the Titanic, the Estonia and the Costa Concordia were destroyed. The student knows how to apply the stability rules and regulations in her/his design work.

Content

The focus in the Hydrostatics and Stability - course is in the basics of ship floating position and stability, and their impact on safety. Examples are analyzed manually and with computer programs based on lines drawings and hydrostatic calculations.

Materials

Literature:
For example Ship Stability, Klaas Van Dokkum

Teaching methods

The learned theory will be used to solve calculations and exercises. It is recommended to participate actively in the course and to do the given calculations and excercises.

Student workload

Ship hydrostatics and stability, 7 cr, 187 h

Content scheduling

Principles of stability, boyancy and weight, transversal stability, free surface effect, moving cargo, dynamic and intact stability, longitudinal stability, damage stability, NAPA loading computer

Evaluation scale

H-5

Assessment methods and criteria

Two midterm exams á 12 p. possible 4 bonus points from given exercises
Grades:
33% = 8p = 1 (this has to be reached without the bonus points, the stability calculation in midterm 2 has to be right)
41% max =2
55% max =3
70% max =4
80% max =5
max = 24+4 = 28 p
