About the course
Course content
Application of lifting line and lifting surface theory in the design of propulsors, rudders, foils etc. Application of theory and experimental methods in calculation of resistance and in calculation of hydrodynamical characteristics of propellers, tunnel thrusters, azimuth thrusters and waterjets. Hydrofoil and propeller cavitation. Influence of fouling, wind and waves on resistance and propulsion. Propulsor dynamics in waves. Hydrodynamic energy saving measures.
Learning outcome
- To have detailed knowledge about the hydrodynamics of ship propulsion, ship resistance, hydrodynamic lift, hydrodynamic principles of propellers, including cavitation and ventilation. - To have knowledge about the special considerations regarding the hydrodynamics of thrusters, waterjets and operation of ships and propulsion systems in a seaway. - To be able to do computations of resistance, propulsion power of ships by use of experimental, empirical and simple numerical methods. - To master the choice of main dimensions of propellers, as well as simple propeller design. - To master the concepts and terminology of naval hydrodynamics. - With these knowledge and skills the students will be better able to do design and analysis of ships and propellers.
Learning methods and activities
Lectures, exercises and lab demonstration. Some of the scheduled exercise periods might be replaced by lectures. Examination, project, and exercise papers will be given in English only.

Further on evaluation
Aggregated assessment is the basis for the grade in the course. The assessment is based on different parts, a final oral exam (counts 80%) and work (counts 20%), as well as compulsory exercises required for taking the exam. A letter grade is given for each part and a final letter grade will be assigned. Postponed/repeated exams will be oral. For a re-take of an examination, all assessments during the course must be re-taken.
Recommended previous knowledge
TMR4247 Marine Technology - Hydrodynamics or similar. Knowledge of fluid mechanics from introductory university course. Basic knowledge of resistance and propulsion of ships. Programming skills (for example Python or Matlab).
