NAB2022 Ship Technology

Course description for academic year 2021/2022

Contents and structure

Introduction to hydrostatic, stability and trim on ship or vessel. Basic concepts within materials science, shear forces, bending moments, material stress, hull, vessel hull stress, regulations for ship dimensioning. Corrosion, surface treatment, paint and maintenance systems are handled within the course.

Learning Outcome


The student:

- Has basic knowledge in the following areas: Initial stability, trim, list, dynamic and static stability, effect of free liquid surface, icing, loadline and damage stability.

- Has thorough knowledge of structural challenges, vessel strength and which forces are affecting the ship, including regulations for such.

- Understands the need for maintenance and how to assess which methods best to be used.

- Are familiar with maintenance systems and their use.



The student:

- Are able to demonstrate factors which can influence the hydrostatics and stability of a vessel.

- Can use proper terminology and perform stability calculations.

- Are able to perform basic calculations in areas such as; instability, trim, list, dynamic and static stability, free liquid surface, icing, load line and damage stability.

- Can assess the loading conditions of a vessel based on the allowed shear forces and bending moments.

- Can carry out calculations for strength and strain, and use shear force- and bending moment diagrams.

- Are able to operate a vessel safely based on the vessel's strength and construction.

- Can assess which methods of maintenance are necessary in a given situation, and how these are carried out.

- Are familiar with maintenance systems, and thereby able to follow up planned maintenance.


General Qualifications:

The student:

-  Has theoretical competence required for the subject as per STCW 78 as Amended, tables A-II/1 and A-II/2.

- Has insight into relevant academic and professional issues.

- Can exchange opinions and experiences with others with a background in the field, thereby contributing to the development of good practice
