ABSTRACT
Recently, the greater part of a capacity of materials mobilization uses containers. The construction of
new port and high-speed medium size container ship for the transportation of merchandise is very
important.
The problem of ship stability is important because of the direct influence to the loss of the human-life,
ship, and merchandise, etc. The stability of container ship during the sailing is not the problem because
it is reflected in the design process. However, the assessment for ship stability during container
loadinghnloading in port depends on experience as yet.
In this paper, the model-based simulation system is introduced, which is able to assess ship stability
during container loadinglunloading, using ENVISION, the general-purpose simulation system.

1 INTRODUCTION

The emerging information and communication technologies of shipbuiIding industrial environments
are rapidly changing. To respond to the situation, a new paradigm has been matured with new concepts
such as the concrete method. Especially, all the efforts are shown to be concentrated to realize the
concept of Simulation Based Design(SBD) based on three dimensional Computer Aided Design(CAD)
model.
In this paper, new methodology for design and operation of ship is suggested, and for the verification
of suggested methodology, the system for stability assessment of ship during container
loadinghloading was developed. The developed system consists of geometric modeling subsystem,
basic calculation subsystem, and Computer Aided Engineering(CAE) subsystem. The function of the
geometric modeling module is to perform the modeling of the hull form and compartment of the
high-speed medium size container ship, and the shape of the container crane, the transfer crane, and
the port. The function of basic calculation module is to provide the results of calculation of
