• Shipbuilding, Semester 1, position 1

Within the course, students are introduced to the fundamentals of marine hydrodynamics and how the basic parameters of a ship's hull form influence ship resistance. They are trained to determine ship resistance for common types of seagoing ships by applying traditional engineering methods. Additionally, the course explores other conventional and unconventional types of ships from the perspective of ship resistance.

1. The student is thoroughly acquainted with the basic physical phenomena that characterize a ship's navigation. In this context, traditional, but also contemporary methods for solving complex physical phenomena, in order to determine a ship's calm water resistance, are considered. Special attention is given to conducting model-scale experiments and procedures involved in extrapolating and applying these findings to a full-scale ship. 2. The student is capable of applying comprehensive knowledge of mathematics, fluid mechanics, and basic engineering principles to determine the resistance of a ship during navigation. 3. The student demonstrates the ability to conduct a comprehensive analysis of the primary and secondary characteristics of a typical sea-going ship’s hull form. The purpose of this analysis is to optimize the hull form, with respect to ship resistance. 4. The student can assess the impact of selected ship design parameters on ship resistance to mitigate adverse environmental impacts. 5. The student is qualified to choose and apply appropriate empirical and numerical methods to determine ship resistance, considering both the limitations of the waterway and the methods applied. 6. The student can select and critically evaluate relevant technical literature and other sources of information to address complex problems in the field of ship hydrodynamics, with a particular focus on determining ship resistance. 7. The acquired knowledge enables the student to address complex engineering challenges and meet specific design requirements imposed by contemporary trends in naval architecture, particularly those related to ship resistance.

To determine the ship’s main engine power, ship resistance must be determined first. It can be obtained by model tests or by other evaluation methods. Teaching is primarily oriented to the practical application of ship hydrodynamics in common engineering practice. Attention is particularly focused on model tests that are still the most reliable tool as well as on the extrapolation of results from a model to a ship. Theoretical teaching is realized through the following teaching units: a) calculations of ship resistance components, resistance evaluation according to ITTC recommendations/method, b) effects of shallow and restricted water, c) model tests, model‐ship correlation, standard methodical and statistical series, d) recommendations for the design of ship forms, and e) high‐speed (unconventional) craft.

The student should evaluate resistance for a usual sea‐going ship (form) he/she was acquainted with within the subject Buoyancy and stability of ship 1. The obtained results will be used in the project that should be done within the Ship propulsion course. Thus, the student is enabled to perceive the ship as a whole, and resistance itself as a part of applied ship hydrodynamics that is unavoidable in the ship design process. Within the framework of practical teaching, the student is trained to do calculations using a computer i.e. to develop a mathematical model for resistance evaluation by himself. Moreover, some teaching units presented by theoretical teaching involve calculation examples too.

It is necessary that the candidate: has 180 ECTS and has completed the project task in the subject Buoyancy and stability of ship 1
