At sea people learn the practical stability for their ships and their trades, but often
forget most of the theory. In addition to stability, the package also deals with the
basics of longitudinal strength, shear forces and bending moments.
Why Seven Steps?
The seven steps cover the most important parts of the subject:
SHIP STABILITY CD-ROM MULTIMEDIA TEACHING SOFTWARE ON FUNDAMENTALS OF SHIP STABILITY
Code No 818
Ship stability is a key requirement for safe ship operation and must be considered at
the design stage. While the outcome of instability is readily appreciated, the
formulation of the ship stability concept and its physical interpretation can be
difficult to grasp. The limitations of traditional text books become apparent when
dealing with a subject which is based on moving structures as, for example, the fact
that illustrations are highly simplified, making visualisation a challenging task. The
software for teaching ship stability has been designed and developed at the
Department of Ship and Marine Technology, University of Strathclyde solely to assist
in the teaching of ship stability, and to enable users to explore the subject and
acquire an understanding through interaction, animation and illustration.
Program Contents
The study of stability can be broken down in a number of ways and these are covered
in the modules.
Module 1
Basic Concepts of Stability - provides a general background to the subject,
introduces some basic terminology, and the three basic modes of stability
Transverse Stability at Small Angles - principles of transverse stability at small
angles, measures of stability and associated formulae
Transverse Stability at Large Angles - looks at the transverse metacentre at large
angles and introduces curves of statical stability
Effects of varying ship parameters - this section allows users to vary certain ship
parameters, such as beam, and compare the resulting stability curves.
Module 2
Longitudinal Stability - applies the principles covered in Module 1 to ship stability in
the longitudinal direction
Introduction to Damage Stability - considers the effects of hull damage on ship
stability and looks at watertight subdivision, floodable lengths and associated
calculations
Key Features
The program content has been organised in such a way as to suit users with different
levels of knowledge on the subject, and can be used equally for self-learning or
revision purposes.
In addition to the basic theory of ship stability, the following features have been
incorporated into the program in order to provide a more comprehensive learning
package:
Glossary of terms, Search facility and Real Life facts.
The second video is more advanced, showing steps 4-7
Transverse stability
Longitudinal strength and stability
Rolling of ships
Turning at speed
This teaching and learning package consists of two videos and a booklet and will be
of great use for:
Teachers and students on maritime and naval architecture courses, including
STCW certificates of competency
Company training officers and ships’ officers for refresher programmes and for
introducing stability topics to staff new to their ships and trades
shore-based personnel responsible for working with ships on loading plans,
normal loading procedures, firefighting, contingency planning, salvage and other
emergencies
