Avaliação dos níveis de vibração em um navio: aplicação em um AHTS

Abstract

Initially, the main goal of this dissertation was to analyze and evaluate the vibration levels on board an AHTS ship, comparing them with the limits established by the ship's classification society. Six analyses were conducted that perfectly fit into the established workflow. In these measurements, classic analysis techniques were applied, including Time Waveform Analysis, Order Analysis, and FFT Spectrum Analysis, following the guidelines of the ship's classification society. After obtaining the results, they were compared with the limits set by the classification societies, yielding mostly satisfactory outcomes. To make the procedure even more practical, a web app was developed for swift vibration assessments, integrated with an open-access AI to facilitate compliance verification with the standard.
