Ship Hydrostatics and Stability
The hydrostatic approach to ship stability aims to balance idealized ship weight against buoyancy forces. This textbook is a complete guide to understanding ship hydrostatics in ship design and ship performance.
Adrian Biran guides readers from first principles through basic and applied hydrostatic and ship stability theory, and introduces contemporary mathematical techniques for hydrostatic modelling and analysis. Real life examples of the practical application of hydrostatics are used to explain the theory and calculations; and to illustrate the effect shifting weights and central gravity displacements have on overall ship stability.
Ship Hydrostatics and Stability covers recent developments in the field of naval architecture such as parametric resonance (also known as the Mathieu effect), the effects of non-linear motions on stability, the influence of ship lines, and new international stability regulations for small vessels. Extensive use of computer techniques is made throughout.

Page 2 - Framework for Discussion In order to establish a framework for the discussion of the session topic, it may be instructive to review the definitions of the key words in the theme. "An engineer is a person qualified by aptitude, training, and experience to perform engineering functions". "Engineering is the professional art of applying science to the optimum conversion of natural resources to the benefit of man" (2) . Clearly, there is no need to dwell upon the definition of an engineer.
