Noise & Vibration Management on-board Marine Vessels

The article discusses the critical research area of Noise and Vibration (N&V) management on-board marine platforms. It highlights multiple applications, including crew comfort, preventive maintenance, and underwater noise management. The evolution of N&V studies, spanning from mechanical devices to advanced computational methods, is outlined. Various purposes of N&V studies on marine vessels are detailed, emphasizing crew habitability, equipment maintenance, and acoustic stealth for naval platforms. The article also covers noise and vibration sources, measurement parameters and tools, as well as analysis techniques. It discusses various paths of noise transmission, including airborne, structure-borne, duct-borne, and fluid-borne paths, along with relevant regulations and standards set by international bodies like the IMO and ISO. Stakeholders involved in noise mitigation, applications in crew habitability and failure analysis, and the evolution of noise regulations on ships are also highlighted. The article discusses the significance of vibration analysis and condition-based preventive maintenance (CBPM) in maintaining ship machinery. Transfer Path Analysis (TPA) methods are explored for understanding mechanical vibration transmission. Furthermore, the article addresses challenges in research, such as the lack of an open database for ship parameters, and proposes the automation of noise and vibration analysis as a direction for future study.
