The analysis of induced vibrations by propulsion system excitation of an 8000 tdw chemical tanker, by a FEM approach

Year: 2025

Type: article

Abstract: Nowadays, ships become larger and more flexible, requiring that their design be evaluated also according to the vibration criteria, being induced by the onboard propulsion system. The vibration onboard comfort addresses the conditions ensured for humans, namely passengers, and crew, setting up the reference quality for living during navigation conditions. Also, excessive levels of vibrations can cause fatigue issues, damage structural elements, and also various ship’s equipment during exploitation. This paper uses in study an existing operating vessel, for a preliminary vibration analysis stage, by using the FEM approach for the natural modes and the propulsion system-induced vibrations.
