As already observed, adapting an existing port to new maritime requirements is often a difficult, time-consuming and expensive affair, especially if insufficient flexibility was incorporated in the original design.

However, rather than just dwell on the detail of such techniques, particular attention is given to the steps which have to be taken by the designer to prepare for their use and interpret the results.Particular attention is drawn to Appendices C and D dealing with squat and the determination of depth in muddy areas.This requires the assessment of a number of key elements, including vessel size and behaviour, human factors in ship handling and effects of the physical environment.This is a consequence of the slow response of large ships to rudder action or engine movements.
Developments in sea transport are continually stimulated by technological improvements and changes in transport demand.
In this report the more complex areas of Detailed Design are discussed in some depth and the computer-based techniques which they use are described.
All of the above considerations lead naturally to a requirement for a logical and rationally-based design process which will allow, among other things, for the determination of the horizontal and vertical dimensions of the port's approach channels and manoeuvring areas.
For deepwater ports which must receive large ships, in excess of 50,000 dwt say, an important problem to be faced is the fact that the actual track of these ships may deviate considerably from the ideal.
