Analysis of the amplitude-frequency characteristics of the on-board pitching obtained during the operational flight

Abstract

Problems with ensuring the safety of navigation of vessels in waves and with optimizing the parameters of the vessel's movement currently arise, in particular, due to the inability to use new achievements in navigation of related scientific disciplines, such as the theory of ship pitching, oceanography. This is partly due to the lack of methods for obtaining the spectrum of actual waves in the vicinity of a ship that is on an operational voyage and does not have the ability to make stops to record waves, the absence of ship pitching recorders in the widespread practice of navigation and the lack of software for complex processing of the necessary information. At present, the SGUVT has created software and hardware complexes suitable for use by the full-time crew on ships in operation.
 Modern software and hardware complex provides the possibility of automated recording of the ship's pitching and its processing. The pitching record can be processed to obtain an amplitude.
