Abstract

In this thesis, two separate PC based maneuvering simulation programs have been developed using FORTRAN programming language. The first is for conducting displacement hull maneuvering simulation (it is capable of simulating all the standard ship maneuvers) and the second is for conducting planing hull maneuvering simulation (it is capable of simulating planing hull turning circle maneuver). Both programs are valid only when the vessel is moving in unbounded, calm, and deep water. A captive model test plan for a Zodiac Hurricane 733 craft has also been developed in this thesis, which can be used to measure and create the hydrodynamic coefficients database which is required as input by the developed planing hull maneuvering simulation program. -- For validation studies, standard maneuvers of ESSO OSAKA have been simulated using the displacement hull program and turning circle maneuvers of a simple planing craft (for which Katayama has published full scale sea trial results) and the Zodiac Hurricane 733 craft (for which Virtual Marine Technology provided some full scale sea trial data) have been simulated using the planing hull program. Simulation results have been compared with full scale sea trial results wherever data was available and good agreements have been found. Observed discrepancies in a few cases have been explained.
