The course gives a general description of the development of ship damage stability standards, taking especially in consideration relevant accidents and the identification of weak points in the deterministic standards. A comprehensive description of the theoretical foundations of the probabilistic method, in general, will then be provided. This will be followed by an overview of the existing regulations (Resolution. A.265[VIII], MSC.19(58)) based on the probabilistic method, with special emphasis on the differences between different regulations. The new harmonized probabilistic regulations will also be reviewed. These methods will be applied through case studies, aiming to highlight some common difficulties found in its application. Hydrodynamic part of the course will be devoted to wave-induced loads on damaged ships with particular emphasize on differences between wave loads on intact and damaged ships. This course requires the students to have familiarity with undergraduate mathematics and statistics Exercises will be mainly carried out in a computerized classroom. To perform the exercises there is an academic network license application (GHS) General Hydrostatics System in which the problems of the damaged ship stability for different types of ships and damage are modeled.

Student responsibilities:

Grading and evaluation of student work over the course of instruction and at a final exam:

Total course mark percentage summary: Ship outfit individual assignments 1, 2 & 3/seminar work 40% of mark Colloquium 1, 2 i 3 ( or written exam) 30% of mark Oral exam 30% of mark Total 100% Course grading for the final mark 50% - 60% 2 (satisfactory) 61% - 75% 3 (good) 76% - 90% 4 (very good 91% - 100% 5 (excellent)

Methods of monitoring quality that ensure acquisition of exit competences:

Students individually work on practical assignments, ship design project and make necessary reports. Assignment results are commented with the students. By interaction with the students during lectures, by asking questions, the continuity of the comprehension of teaching content is checked and so as acquisition of competencies and skills in accordance with the learning outcomes.

Upon successful completion of the course, students will be able to (learning outcomes):

After successful attendance of this course the student will be able to: - Connect the spatial representations of the ship with the features of cargo. - Identify damaged conditions (progressive, intermediate and transient) - Create a ship form in the associated tool - Establish tanks and ship divisions in the associated tool. - Calculate using the probability method the subdivision index. - Propose a new subdivision of compartments by optimizing the subdivision with respect to the subdivision index - Develop the ability of synthesis of the project in relation to the ship"s damage stability taking into account the different types of ships.
