Single-Course Dansk 5 ECTS

Fundamentals of ships and other floating structures

Overall Course Objectives

To give the students an introduction to the scientific methods applied to analyse and solve problems within the maritime field in connection with ships and other floating structures. Focus is primarily given to calm-water conditions without waves, and the course has two main themes: (1) Hydrostatics and (2) Resistance and propulsion. The students will be able to calculate hydrostatics and stability, including damage stability. Furthermore, the course will train the participants in analysing the propulsion of a ship and determine the necessary propulsive power with maximum efficiency. Finally, the course introduces the most basic concepts about ocean waves.

Learning Objectives

  • describe the geometry and function of ships and large, floating ocean structures,
  • explain hydrostatic stability, including the effect of changes hereof because of moving of weights, free surfaces, etc.,
  • make intact and damage stability calculations for floating structures in calm water,
  • conduct an incling experiment of a model-ship and produce the associated computations,
  • explain how forces in a simplified ship hull girder in calm water are distributed,
  • describe the prerequisits related to model tests and calculations of resistance and propulsion of ships,
  • explain the relevant theory connected to model tests focused on resistance and propulsion (Froude scaling),
  • make the extrapolation from model to full-scale using ITTC-1978 method or equivalent method,
  • describe the functioning of a propeller and explain the use of propeller diagrams, e.g. Wageningen B-series propeller,
  • explain the general principles of the interaction between ship, propeller, and engine,
  • determine the engine size in accordance with ship and propeller,
  • describe ocean waves through a wave spectrum

Course Content

Function and geometry of ships and larger floating structures, intact and damage stability of floating vessels, and hull girder loads in calm water. Resistance and propulsion in calm water.
