In order to improve the intelligent level of ship engine room operation and maintenance (O&M), a technical route is developed according to the characteristics of the engine room equipment, such as variety, quantity and complex coupling relationship, and propose a ship-shore integrated intelligent O&M system for ship engine room.

By analyzing the technical development trend of the intelligent O&M system of an engine room at home and abroad, an intelligent O&M system that conforms to the characteristics of an engine room is designed by integrating the technical advantages of health management, big data mining, digital twinning, lightweight data transmission and so on.

A data-brain enabled functional framework, platform design, operation system, operation process and key technology application of an engine room intelligent O&M system are designed.

The results of this study can provide references for the design and application of the intelligent O&M system of ship engine room.
