Detailed description of topics:

The course is designed to provide all future naval architects with sufficient insight in the design and behaviour of ship and offshore structures, to teach them to make an optimal conceptual design. To teach them the impact of fabrication and other limiting factors. The students will learn the more important structural analysis methods.

The course places the structural design within the context of the overall design of ships and offshore structures. The history and background of the field is put in the perspective of further development.

The principles of the conceptual design of the structure are treated, starting with the structural tasks. Economic and fabrication considerations can restrict the design.

The behaviour of beams and plate, stiffened or non-stiffened, gives the elements for further analysis of the structure. Various loads are possible and determine the responses, leading to a variety of failure modes.

Learning goals: To be able to:

·       Understand and discern the different aspects of the discipline of ship structural design.

·       Understand and produce the structural conceptual design of a ship or platform, its components and its details.

·       Use advanced plate theory both in-plane loading and bending with small and large defelection situations, apply plastic analysis and determine permanent sets under influence of lateral plate loads

·       Determine the buckling strength of unstiffened and stiffened plates, understand the post-buckling behaviour of plates and ship components

·       Understand and apply the methods to evaluate the ultimate longitudinal strength of the ship hull girder

·       Apply general theory of torsion for thin walled sections in case of unrestrained warping

·       Calculate the torsion strength of thin walled sections in warp restrained situations as appear in hulls of open type ships and to evaluate various ways to provide sufficient torsion strength

Design content:

The course addresses the (structural) design of ships and offshore structures. About one quarter concerns conceptual design, the remaining part concerns response analysis and the impact of other factors on the design.
