Rapid development in computer technology today has revolutionized the method used to predict ship hydrodynamic complex systems by application of numerical simulation approach. One important predictiontechnique made feasible by high-speed computers is the time-domain simulation especially in the prediction of ship motions, sea-keeping and also manoeuvring. On the other hand International Maritime Organization (IMO) standard for ship manoeuvrability has hastened the need for more accurate prediction of ship’s manoeuvrability at the early design stage. There are many test methods available for manoeuvring prediction such as free running and captive model tests. However these methods are expensive and time consuming. As an alternative, the numerical simulation method is taking place the current principal approach. This paper presents a manoeuvringassessment of an Offshore Supply Vessel (OSV) based on the numerical time domain simulation approach. Manoeuvring time domain simulation programmed was developed by using Matlab Simulink software.Prediction of vessel swept paths was obtained by double integration of acceleration in the surge, sway and yaw axes. Simulation result shows that the manoeuvring criteria of an OSV comply with the IMO standard.
