SHIP RESPONSE IN DIRECTIONAL CONTROL TAKING ACCOUNT OF FREQUENCY DEPENDENT HYDRODYNAMIC DERIVATIVES
The fluid forces acting on a ship have significant time history effect and give rise to frequency dependence. The use of quasi steady theory cannot therefore be applied to all ship motion problems. However provided care is taken in the conduct of experiments and their analysis, problems arising from the more complex nature of the forces can be avoided or taken into account. For the greater majority of ship motion prediction quasi steady theory is still valid though again care should be exercised in its application.
