Sensor-Based Operational Dataset of Main Ship Machinery (ARC Gloria)

This repository provides consolidated 1 Hz nominal operational sensor datasets from the Colombian Navy training ship ARC Gloria, covering 2025-09-08 to 2025-12-19 (local time, America/Bogota). It includes time-series data for the main propulsion engine and the generator engines (port and starboard), merged from multiple navigation legs into tidy, timestamp-aligned tables (one variable per column).

Records are not continuous due to real operating conditions: equipment on/off, sailing under wind power, port stays, and intermittent acquisition, so the time index contains gaps (including multi-day gaps). A substantial share of timestamps correspond to non-operating states (e.g., low/zero RPM), while operating segments show physically consistent pressure and temperature ranges. Missing values are preserved as NaN, and some variables may be unavailable or recorded as constant zeros in specific legs; these artifacts are kept as recorded for transparency and reproducibility.
