Course objectives:

Introduction and application of methods for evaluation of floating structures.

Student responsibilities:

Orderly attendance of lectures and excersises, as well as independant project draft.

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

Through oral exam and evaluation of drafted project.

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

1 . Calculate critical stresses of rods/beams, plate and stiffened panels in elastic and elastic-plastic area using design equations.

2 . Check the feasibility of structural elements according to the Rules of the classification society

3 . Calculate the ultimate strength of the stiffened panel using the nonlinear finite element method.

4 . Analyze different calculation methods of ultimate strength of the ship's hull.

5 . Apply principles and fundamental knowledge in the field of special finite elements, analytical and numerical methods for control of geometric and material nonlinearities
