Course objectives:

Advanced methods for ship structural design. Application of OCTOPUS, MAESTRO, MSC/NASTRAN and DEMAK software.

Student responsibilities:

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

Evaluation of project/seminar and oral exam.

Methods of monitoring quality that ensure acquisition of exit competences:

Quality monitoring is assured through: -initial discussion during which the level of previously obtained relevant knowledge and abilities is determined -continuous monitoring of contemporary research in the field of optimization/design of floating objects structures -self-evaluation of course and applied lecturing methods

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

Upon course completion students will be able to: - formulate design problem in area of ship structural design; - choose relevant design models for rational ship structural design; - apply basic knowledge and principles in ship strength and optimization technique in rational ship structural design - use advanced modelling techniques for ship structures in contemporary computer tools (DEMAK, MAESTRO, CREST,) in order to obtain rational design variants. - use profession specific foreign language (English) regarding the analysis of ship structures.
