Course objectives:

Introduction and application of methods for evaluation of floating structures.

Student responsibilities:

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

Through oral exam and evaluation of drafted project.

Methods of monitoring quality that ensure acquisition of exit competences:

Quality monitoring is assured through: - continous check of the project progress; - occasional knowledge checks. -selfevaluation of the course and applied teching methods

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

Upon course completion students will be able to: - apply principles and fundamental knowledge in the field of special finite elements, analytical and numerical methods for control of geometric and material nonlinearities and ultimate strength in problems concerning analysis of ship structures; - use advanced modelling techniques for ship structures in contemporary computer tools (NASTRAN, MAESTRO) in order to obtain rational design variants. -formulate hull girder ultimate strength problem and choose applicable methods for solving the problem - to calculate critical stresses of rods/beams, plate and stiffened panels in elastic and elastic-plastic area - to make and evaluation rational judgment regarding different stiffening system of ship structurs w.r.t buckling capability - use profession specific foreign language (English) regarding the analysis of ship structures.
