This repository presents an Excel file with two databases related to different alignment configurations of bearings in the propulsion system of a studied AHTS (Anchor Handling Tug Supply) ship. The databases contain the deflection values for each bearing and its approval status (1) or disapproval status (0) according to three main alignment approval criteria (SNAME) for 15 loading conditions / sea states to which the ship is subjected. These 45 results are summed up, evaluated, and then an alignment approval percentage is obtained. The first database contains 1000 samples, and the second contains 2500 samples. A statistical report in HTML of the first database is also being shared, generated using the "Profile Report" tool in Python.


Steps to reproduce

Data was generated by excel usil random functions varying offsets bettween possible adjusted values and calculating the results by the stiffness Method using the alignment acceptance criteria from SNAME.
