Title: PROCEDURE TO ASSESS MANOEUVRING SAFETY OF SHIPS IN HARBOURS
Abstract: This paper describes procedures to systematically assess manoeuvring safety of ships in harbours and narrow waterways. The first step is to build a suitable manoeuvring plant, taking into account experts' knowledge, ship performance of elementary manoeuvres and son on. The second is to evaluate the manoeuvring difficulty caused by environmental conditions, control procedures, etc. and these are achieved by fast time simulations in which the models of ship and human operator are employed. Taking into account the complicated aspect of the human operator into account, real time simulations are carried out as the third step, and the allowable limit in safe manoeuvring is confirmed. The final step is to carry out investigations on board, and special attention is paid to actual circumstances in a real port or waterway. The application of fast time simulation procedure, together with experiments employing real time simulators is also discussed, and it is shown that the procedure is effective for parametric studies in assessment work, for example, in understanding the all the aspects of environmental effects.
