**5. Conclusions**

This chapter has successfully demonstrated the process of developing a virtual simulator using an open-source modern game engine software to develop "serious game" as a training system. By integrating different game objects using event-driven programming that is provided within the development software, it can be seen that modern game engine is capable of producing an appropriate level of accuracy in a fraction amount of time and at a low cost. Pilot training is useful for search and rescue operation, dynamic positioning of the drill string, subsea operation, and inspection tasks. Working at the simulator console, the trainees learn necessary flying skills and experience challenges of offshore operations before their first jobs. The virtual ROV's simulator creates a powerful and an efficient project preview and assessment tool for training. The low-cost ROV's pilot simulator can simulate live inputs from the vessel, rig to position the drill string and co-ordinates work operations efficiently in an offshore environment. It dramatically enhances the current training capability, workplace safety in an uncertain environment and reduces maintenance cost as the present cost of a complete ROV's pilot simulator is quite expensive to use and maintain.

Further research can be made to examine whether a pilot candidate who experienced the training in a simulated environment will perform better than those who do not have prior training. The design of different controllers can be implemented to add robustness to the ROV operation in underwater. Further development could be shown to improve on the simulator to suit the requirements of the classification society and specifications. It will be necessary as ROVs are used in many underwater tasks with more autonomy in its operations. However, it is still not possible to replace the decision-making process of a human operator in the loop.
