Determination of the ship's pitching parameters during an operational voyage

Abstract

In this article, it is proposed to use a hardware and software complex created on the basis of microcontroller technology to record and visualize the parameters of the ship's pitching during an operational voyage. The ability to continuously record the parameters of the keel and side pitching of the vessel in various weather conditions and the changing loading of the vessel allows you to quickly monitor the stability parameters and improve the safety of navigation in difficult weather conditions of stormy navigation.
 The track recorded in MS EXCEL with the pitching parameters and the current time allows you to compare the recording time with the effect of various hydrometeorological conditions, taking into account both wind and wave effects on the vessel, including from hydrometeorological objects located at a considerable distance from the current position of the vessel. These data make it possible to carry out a harmonic analysis of pitching, to obtain the frequency spectrum, phase-frequency characteristics, proper pitching period and amplitude-frequency characteristics of the vessel.
