Sensor-Data-Driven Prognosis Approach of Liquefied Natural Gas Satellite Plant
Round 1
Reviewer 1 Report
The manuscript proposes a sensor data-driven prognostic approach for predictive maintenance of LNG satellite plant. The study includes two parts, firstly data validation and correction is presented to transform raw data into reliable validated data; secondly prognostic approaches for gas consumption and remaining time to refill plant tank are presented. The manuscript is well written and organized. But the reviewer still have some concerns regarding the work, especially its novelty. Therefore, the paper cannot be accepted for publication in its present form. Some major concerns are as follows:
1.Related work is well reviewed, but work novelty should be clearly highlighted to indicate the difference to previous studies and its benefits;
2. It seems that data correction and validation techniques are commonly used techniques, did the authors make any modifications for the specific purpose in LNG satellite plant?
3. Why two methods are used for the prognosis, where are they from and how are they selected?
4. As two prognostic approaches are used in the analysis, it is necessary to compare their performance such that their pros and cons can be clarified.

Reviewer 2 Report
In general, the work is done well, the subject matter is part of the issue of liquefied natural gas LNG storage, especially in the context of satellite stations and the challenges associated with their operation. I suggest a slight correction of the title of the article - instead of: Liquid-Natural-Gas enter: Liquefied Natural Gas (this is the more correct form). In line 29, liquid phase is more suitable than liquid state. I think verses 53-56 are not necessary in this article, although they can ultimately remain. Regarding the description of the pressure changes in the LNG tank (lines 145-151), it should be mentioned that the pressure increase also limits LNG evaporation by moving the equilibrium point towards a higher temperature. Figure 2 should also include the measuring (metering) system at the regulating system. In line 194 mentions a database in a .txt file, I think it would be more convenient to send data also in .csv format. Descriptions of the tables should be placed above the tables. In the proper part of the article I have no further comments - especially the substantive part.
Eventually, the conclusions could be slightly extended.
