The purpose of this study is implementation of the simulation for subsea production system. Subsea production system is installed under the environment of high pressure and low temperature. Most of processes of production are proceeded in the subsea equipments. Therefore, the understanding and study of subsea production system is very difficult because people cannot observe the process directly. The simulation system can be a solution for this difficulty. In this research the information models and 3-D graphic model for the subsea equipments were built using the object-oriented technology and 3-D CAD. The entire system was implemented with help of simulation software, 3-DVIA Virtools. The simulation system of subsea production system was tested with several scenarios of production process. The test results showed that the simulation system is very useful for the understanding of subsea production system and can be a good education tool.
