Prof. Adrian LUNGU
Code = EMSHIP S3-1 (Semester 3)
Workload: 60 h lecture, lab
Number of credits: 5
Objective:
The objective is to provide the specific knowledge in the ship hydrodynamics, focusing on the manoeuvrability, a subject that is not covered by the other courses. The course will approach not only the theoretical aspects related to the complex phenomena that occur, but also on practical and experimental issues. Basically, the classes will cover the following main topics:
a)Fundamentals of manoeuvring theory.
b)Experimental approaches.
c)Rudders.
Contents:
Simulation of manoeuvring with known coefficients
Force coefficients
Physical explanation and force estimation
Influence of heel
Shallow water and other influences
Stopping
Jet thrusters
Experimental approaches
Manoeuvring tests for full-scale ships in sea trials
Model tests
Rudders
Fundamental hydrodynamic aspects of rudders
Rudder classifications
Interaction between rudder and propeller
Interaction between rudder and ship hull
Rudder cavitation

Prerequisites:
The lecture “Ship Manoeuvrability” (5 Credits) is an advanced and complementary design oriented course in the ship hydrodynamics, focusing mainly on the manoeuvrability. It follows the preparation in advanced ship hydrodynamics provided by the Ecole Centrale de Nantes, therefore the following lectures have to be passed successfully:
-
- Water Wave and Sea State Models for Ship Design
- Seakeeping: Theory & Numerical Modelling
- CFD for Ship Hydrodynamics
- Experimental Ship Hydrodynamics (5 ECTS)
Form of exams:
Written exam (3 hours) , oral (1 hour)
