Course Objective

This course is intended for graduates with an interest in design of ships or offshore structures. It requires a sufficient background in structural mechanics. Computer applications are utilized with emphasis on the theory underlying the analysis. Hydrostatic loading, shear load and bending moment, and resulting primary hull stresses will be developed. Topics will include: ship structural design concepts, effect of superstructures and dissimilar materials on primary strength, transverse shear stresses in the hull girder, and torsional strength among others.

Learning Outcomes of the Course Unit

1   To be given professional competence for design and analysis of lightweight stiffened shell structures that are typical of ships and offshore sturctures
2   To be able to appreciate the underlying theory of the applications (i.e. software, classification rules)
3   To be able to identify and discuss the functionality of the structural elements in a ship structyre both from a global and local perspective
4   To be able to carry out a structure stability and buckling analysis of a stiffened thin-walled lightweight structure
5   To interpret and use classification rules in order to design lightweight structures according to given design criteria
6   To understand and discuss the meaning of the effective flange concept
7   To evalute critically and compare various design concepts with respect o material, geometry and structural aspects
