Abstract:

The paper summarizes an experimental and analytical study of ship manoeuvring, with special emphasis on the use of a research-purpose simulator for evaluating the behaviour of large tankers in deep water as well as in harbour entrances and canals. In an introductory Section some new results from full-scale measurements and simulator studies are given to illustrate the demands put on a mathematical model in the two extreme applications course-keeping in deep water and manoeuvring in a canal bend. Well-known derivations of rigid body dynamics and homogeneous flow solutions for forces in the ideal case are included to form skeleton of the mathematical model. Separate equations handle helm and engine controls. Author
