The MED3DH is full mission, hardware type Medium Speed Engine Simulator and has been based on very modern solutions, being presently used in medium-sized, computer controlled, engine rooms (one four-stroke type main engines with reduction gear and controllable pitch propeller). This kind of computer controlled engine room is very typical configuration applied on modern container ships.

The MED3DH virtual reality simulator provides for a new approach to navigation through the different system's elements, allowing for an easy and quick access to basic engine room operation (valve opening/closing, setting position of switches, push-buttons etc.). This has been possible due the application of state-of-the art 3D visualisation with zoom techniques.

The latest development includes also a combination of 3D and 2D diagram presentation, which enables to follow how a certain device really functions and gives a complete picture of its structure.

The presented solutions have improved considerably the level of simulator fidelity in relation to real machinery. In consequence, it was possible to eliminate the disadvantages of the engine room simulator with typical 2D presentation consisting in a schematic and simplified presentation of machinery systems.

This simulator is designated for training students of maritime academies as well as for different types of marine vocational training centres. The simulator has universal features and may be used both for training merchant and navy fleet crew.

The main purpose of the MED3DH simulator is the practical preparation of the trainee for engine room operation, and more particularly:

- familiarization with the basic engine room installation (compressed air system, fresh and sea water cooling system, lubricating, fuel oil system etc.), specially taking into account training on the base of modern, computer controlled engine room;
- acknowledgment with main engine and auxiliary equipment exploitation procedures;
- propulsion system manoeuvring (main engine - reduction gear - CPP);

The software allows for the simulation of opening/closing of basic valves and auxiliary equipment operation in engine room installations by application of 3D visualization. The software also generates the main engine room's sound.

The MED3DH simulator has been equipped with a hardware consoles and panels that enables main engines, gear, CPP, auxiliary machinery and electric system's operation and control.
MED3DH simulator consists three main elements:
- Engine Control Room ECR with main engine control console and main electric switchboard,
- Engine Room with two PC projectors and control console for 3D visualization combine with diagram presentation,
- Instructor Room.

The main engine's starting and stopping procedure is effectuated on hardware type control consoles and Electric Switchboard panels.



The basic operation with auxiliary sub-systems, identically as in real modern ship, is performed by " mouse clicking" operation on the PC monitors screen. On the PC's screen diagrams related to specific installation like fuel oil, compressed air system, cooling system, lubricating system, steam system, etc. are presented. For security reasons the Engine Control Room is equipped with two identical PCs with monitors. In case of one PC failure, second one taking systems' control automatically. On the monitor screen by "mouse clicking" it this possible to start/stop the pumps, compressors and open/close the valves which are remote controlled.

All operating procedures which is necessary to perform in engine rooms (outside of Engine Control Room) are effectuated is separate room equipped with two projected screens.
One screen presents engine room elements is 3D visualization and anther one in form of diagram related to specific and selected compartments of engine rooms, for example auxiliary generators' room, emergency generator's room, compressed system room etc. Selection of important from exploitation point of view engine room's elements is performed by zoom techniques.

The simulator software's language version is English.

The simulator has been developed in compliance with:
- STCW Code: Section A-1/12 and Section B-1/12.
- ISM Code: Section 6 and Section 8.
