This includes: constructing a marine base model; selecting multiple locations in the marine operation area as reference points; constructing a sea surface model using the reference points based on least squares and wave spectrum theory; and scaling down the sea surface model according to a certain ratio to obtain the marine base model; introducing a marine environment fabrication device into the marine base model to establish the correlation between the marine base model and the marine environment; and importing the marine operation environment data into the marine environment fabrication device. In the device, the marine environment manufacturing device replicates the marine operation environment data and maps the marine operation environment data onto the marine base model to obtain the marine environment model. When constructing the sea surface model, different locations are selected multiple times as reference points for the marine operation area to obtain multiple sets of reference points. Multiple sea surface models are then obtained based on least squares and wave spectrum theory for each set of parameter points. These multiple sea surface models are then analyzed sequentially to determine the errors between them. The sea surface model with the smallest error is then scaled down according to a certain ratio and used as the marine base model. Before adjusting and controlling the production equipment according to the production plan, a lifespan prediction is performed on the industrial equipment. This lifespan prediction includes: Acquire the aforementioned marine operational environment data; Based on the accumulated data on the marine operating environment, an environmental knowledge base will be constructed. The environmental knowledge base is combined with the drilling platform structure and component knowledge base to obtain the data information of the industrial equipment; The life model of the industrial equipment was obtained by using fatigue life of the specimens and corrosion fatigue experiments of the specimens in the seawater environment. The remaining service life of the industrial equipment in marine operations is predicted based on the life model. The remaining service life is dynamically adjusted based on changes in the marine operating environment data. When the marine operating environment data changes, the remaining service life of the industrial equipment in marine operations also changes, and is determined using the following formula: In the above formula, D i This represents the remaining useful life value obtained in the i-th iteration, where min indicates taking the smaller value, and c il T represents the remaining service life of component l in the i-th iteration of an industrial device. i T represents the remaining useful life time obtained in the i-th iteration. i-1 This represents the remaining service life obtained in the (i-1)th iteration, and α represents the preset adjustment parameter. Then, based on the remaining useful life value D obtained in the i-th iteration... i The judgment result is as follows: Where H represents the preset time length, and G represents the judgment result, when G = P(min{c il When G = Q, it indicates that the remaining service life of the industrial equipment in marine operations is less than the preset time length, and maintenance reminders are required for the industrial equipment. When G = Q, it indicates that the remaining service life of the industrial equipment in marine operations is not less than the preset time length, and maintenance reminders are not required for the industrial equipment. The preset time length is determined based on the production cycle of the industrial equipment.
