The paper presents a concept of elemental manoeuvres that may be used for analysis of ship handling training (including the training with manned model ships) and for simulation of complex manoeuvring scenarios. It shows a set of postulated elemental manoeuvres. A fuzzy clustering method is introduced and applied for the classification of manoeuvring patterns. The fuzzy clustering algorithm is used for the extraction of elemental manoeuvres from the records of ship handling manoeuvres of LCC model ship. The best set of variables for the extraction of elemental manoeuvres consists of normalised ship velocities and controls.

The paper describes the problem of aiding the harbour layout design through computer simulation of ship motion. The key aspect of this support relies on treatment of the ship and the commanding pilot as a stochastic sensor testing the given harbour layout under varying environmental conditions. The role and effectiveness of the ship motion simulation in the harbour design are discussed in reference to other existing harbour design support methods. The paper presents an example of hte simulation experiment which was used for the selection of the harbour layout during planning of the expansion of Port of Callao, Peru. Such example may be used as a pattern for nautical analyses with the applicatin of shiphandlind simulation technology. The paper also evaluates the degree of fulfilment of the simulation objectives and points out the areas for further research.
