SD2708 Hull Structural Design 6.0 credits

Skrovkonstruktion

This is a course on design of large complex structures. The main focus is on ship hull structures, but the basic principles and methods are valid for arbitrary structures such as bridges and buildings. The largest ships are well over 300 metres long, and are thereby the largest mobile structures that we humans have ever created. Whether you are facing the task of designing a large tanker, a canoe, a sailingboat or a ferry, the fact that the ship is moving puts specific demands on structure optimization. At the same time ship structures are subjected to large and complex loads from the wind generated sea. The objective of this course is that you after finishing should be able to handles these challenges in design of ships and other complex structures.

Learning outcomes

The learning objectives are that you after finishing the course should be able to:

  • explain the principal layout of a hull structure and the function of the different structure elements,
  • explain what loads a ship structure is subjected to and how these loads are predicted in design,
  • explain how global and local strength (for the whole hull girder and the local structure respectively), stiffness, buckling and fatigue is treated in the design process,
  • apply your knowledge in structure mechanics and technical beam theory from earlier courses in the analysis of global as well as local strength and stiffness,
  • apply finite element methods in direct calculations of local hull strength,
  • explain the purpose and structure of classification society rules,
  • design of a ship hull according to class rules based on rule requirements and direct calculations,
  • make a preliminary estimation of the hull structure weight,
  • discuss hull structural design aspect by using correct terminology,
  • present technical work in writing, in line with standard requirements on content, disposition and language.

Course main content

Lectures on principal layout of a hull structure, the function of the different structure elements, hull loads, and classification rules. Application of beam theory, plate theory and finite element methods in the analysis of ship structures. Project where each student design the structure for a certain ship.
