Module: Ship Safety under damaged condition

Master study Mechanical Engineering


Imparting knowledge about the buoyancy of bodies in a damaged state. In addition to the physical fundamentals, deterministic and probabilistic criteria for the evaluation of the buoyant condition resulting from damage are presented. Leakage safety regulations are discussed based on this. In a further focus, the capsize safety of intact ships is considered. Here, in addition to quasi-static heeling moments, the rolling behavior in regular and irregular sea states is analyzed and evaluated. Questions of WHAT, WHY, and HOW are brought to the fore. Knowledge of the structure of relevant regulations will be provided to the extent that listeners can evaluate their principled approaches. It is not the aim of the course to convey all details of the (continuously changing) regulations. Listeners will be able to understand leakage safety and stability requirements for ships and to consider and evaluate their implications in the design process.

This module is provided in english


In order to deepen the acquired knowledge, additional homework will be handed out in the lecture-accompanying exercises.

Allocation of this course in study

This module is part of the Master's degree program in Ship and Ocean Engineering. Building on the acquired knowledge in the field of ship hydrostatics, more in-depth knowledge in the field of leakage safety, as well as safety against capsizing, is taught. For this reason, the following prior knowledge is required:

  •     completed bachelor studies in engineering sciences including mathematics for engineers I - III
  •     Basics of ship design
  •     Ship hydromechanics I

Oral exam, 30 minutes duration, the module examination is graded.
The date of the exam will be announced in the course of the semester. In order to gain permission to the examination, the homework must be successfully completed.
