technical field [0001] The invention relates to the field of ship and sea big data and numerical modeling, in particular to a numerical model prediction system and prediction method suitable for ship and sea equipment. Background technique [0002] Ships and offshore engineering platforms operate far from the coast, and their equipment operation and maintenance costs account for a large proportion of production costs. In order to improve economic efficiency and enhance market competitiveness, the maintenance of ship and sea equipment is carried out from the stage of post-maintenance and planned maintenance, and gradually enters the stage of predictive maintenance. Through the historical operation, maintenance and continuous work monitoring data of ship and sea equipment, the health of ship and sea equipment The state is evaluated and predicted. [0003] The models currently available for evaluation and prediction can be divided into ship and sea equipment simulation models ...

AI Technical Summary

Problems solved by technology

In the calculation process, because the interface of the calculation simulation software of the ship and sea equipment model is not open and the functions are limited, the ship and sea equipment model cannot update the data, and at the same time, it is impossible to use resources other than the simulation software to perform multiple calculations on the equipment operation status and simulation results. visual display

Especially for more complex ship and sea equipment, the amount of data is huge, and the simulation calculation time of the model is relatively long. During this time, it is impossible to view the operation status of the equipment and the status simulation analysis results intuitively in real time, which is very inconvenient for operation and maintenance guarantee.

[0006] 2. Once the simulation calculation method of the ship and sea equipment model is solidified, it is difficult to optimize and modify the model during the calculation process

[0007] 3. The operation of the ship and sea equipment simulation model depends on the marked sample data, and the real-time data generated by the ship and sea equipment operation and maintenance process cannot be directly obtained and used to correct and optimize the mathematical model. The simulation analysis results are consistent with the ship and sea equipment operation. The situation deviates greatly, and usually only has reference significance, and cannot directly guide the operation and maintenance of marine equipment

[0008] The ship and sea equipment health management model mainly uses the historical operation, maintenance and continuous work monitoring data of the ship and sea equipment to predict the operation trend of the equipment by means of statistics and fitting, but ignores the analysis of the internal operation mechanism of the ship and sea equipment. At the same time, the sample data is mainly aimed at key points and is relatively limited, resulting in problems such as single function of the model, low accuracy, and unreliable prediction results.

At the same time, it does not solve the problem that the ship equipment simulation model is highly coupled and can only be calculated synchronously
