Hydrostatics and stabilityLaajuus (7 cr)

Code: 5031334

Credits

7 op

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.

The learned theory will be used to solve calculations and exercises. Active participation in the course and to the given calculations and exercises is expected for a good success in the course.

Exam schedules

Exam 24.4.2025
Retake 1 exam 19.5.2025
Retake 2 exam 2.6.2025

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 Designer.

Evaluation scale

H-5

Assessment methods and criteria

Exam 70% of the course points, 33% of the exam points are needed to pass the course.
The modeling of the ship hull and calculation of the hydrostatics form 20% of the course points. The exercise shall be passed to pass the course.
The inclining test forms 10% of the course points. The exercise shall be passed to pass the course.
In addition home work allows to collect extra points. These points cannot help in passing the course but can raise the course grade.
Grades:
33% = 1 (this has to be reached without the bonus points)
41% max =2
55% max =3
70% max =4
85% max =5
max is the points from the exam + ship hull exercise + inclining test
