In order to solve the problems of the traditional interactive ship engine room simulation system such as its single simulation form and poor immersivity and realism, a new immersive interactive ship engine room simulation system is designed and implemented, divided into the hardware-in-the-loop （HIL）simulation system and 3D virtual reality (VR) system.

Real-time simulation technology is adopted to realize the real-time connection between the VR system and HIL simulation system through a high-speed network. At the same time, an immersive stereo projection system and multi-station VR system are combined and integrated with the data.

This design realizes the real-time interaction and cooperative operation of the whole system, and the real-time synchronization of the system state between the HIL and VR systems. The internal synchronization characteristics of the VR system are given, and the real-time synchronization of 3D images is realized. Meanwhile, a collaborative interactive operation function of the multi-station VR system is added.

The new immersive interactive ship engine room simulation system proposed herein has guiding significance for ship operation and maintenance management and personnel operation training.
