ABSTRACT
The STCW95 international convention by IMO emphasizes the use of marine engine room simulator as modern marine educational equipment for the training and education of marine engineers.
This paper introduces a new generation real-ship engine room simulation System that has been developed very recently the new generation MERS of SMSC2000 in the Shanghai Maritime University.
This paper also describes the modeling methods for main engine system, and the faults training system of SMSC2000. The faults training system consists of the functional components included faults setting, faults simulating, faults training and operating methods to meet the demand of abnonnal 4operation training.
In order to develop an effective mode, especially the fault model, which is especially effective for the engineers training of Main Engine and the other equipment in engine. it is needed to obtain a sufficient database of marine engine systems actually in service on board; and to build up a series of methods for data collecting system.

1. INTRODUCTION
Modern ships are introducing higher and higher automation techniques today. Ship cost becomes very expensive and it becomes very important to guarantee the safety of both ship and the crew. The use of practical simulator, particularly for the modern ships, becomes essential for maritime education and training. The core of ship's power is shipping engine equipment, so the Marine Engine Room Simulator (MERS), being a modern marine educational equipment on navigation, it can train modern marine engineers effectively and rapidly became a common cognition and affirmed by lots of effectuating. According to International Convention on Standard for Tainting Certificate and Watch-keeping (STCW'95) of IMO (International Maritime Organization), the effective use of MERS emphasize for the training education. So, maritime colleges and universities of most western countries and developed countries have had the MERS .
It is well known to the NORCONTROL Company had a very high level in the world. From the fist MERS developed in 1978 to the newest type PPT2000, they have given a directional influence. Other developed countries like America, Japan, UK have developed some high level MERS.
In China, Shanghai Maritime University has worded on its own high-class MERS named SMSC2000. The SMSC2000 introduced many new technologies such as multi-media, network, system-integration technology, and has reached an advanced international technical level. Its features are as follows:
1) Simulating object is large container ship.
2) Using network technology structure and having distributed collection simulating main controlling structure; also have 15 students stations with real-time controlling coordination.
3) Group removed large mimic penal, combined with hardware and software, mobile display and real-time operating and controlling.
4) Using multi-media technology, realized dynamic picture 's management, the MMI (Man Machine Interface) have a likely looking.
5) On fault setting and diagnosis, using expert system neural network, etc.
6) Placing correlative slot for the future combination with shipping operation simulator of SMU, with realized one-man control-bridge training.
The main engine of simulated ship is HITACHI- MAN-B&W 6L80MC. This paper: describes the investigation and realization of the main engine modeling under steady condition and fault simulation modeling for the MERS. The paper also describes for developing an importance of obtaining a sufficient database of marine engine systems of actual ships in service for the effective fault simulation.
2. M. E. MODELING UNDER RATED CONDITION
2.1 The method of Main Engine Modeling
The marine diesel engine working process is very complex. It concerns with thermodynamics, combustion theory. flow mechanics, material mechanics, heat transfer theory, etc. For, modeling the marine diesel engine, there have been developed some methods such as: modeling of "One-order quasi-steady condition", "Filling and Emptying algorithm", "One - Dimension fluctuate modeling was chosen here. Among them method "Filling and Emptying "algorithm for the main engine modeling under rated condition.
