Prognostication and amelioration of gas ingress in hydraulic systems

A system, comprising:

• a processor;
• and
• a memory, including instructions that when executed by the processor perform operations comprising:
• identifying a stable reading window when operating a carrying system comprising a hydraulic system;
• collecting a set of fluid level readings of a hydraulic fluid in the hydraulic system during a plurality of stable reading windows across a corresponding plurality of operational instances of the carrying system;
• calculating median fluid levels in each stable reading window of the plurality of stable reading windows;
• identifying an increasing trend in the median fluid levels when analyzed as time series data that satisfies a trend threshold of at least a predefined number of successive indications of increased fluid levels in the hydraulic fluid within an analysis window;
• and generating an alert of gas ingress to the hydraulic system,
• wherein the alert causes injection of additional hydraulic fluid into the hydraulic system, and
• wherein generating the alert of gas ingress to the hydraulic system comprises identifying that the increasing trend holds true for a majority of the predefined number of successive indications of the increased fluid levels in the hydraulic fluid.
