Noise & Vibration Engineering Solutions for Marine Applications

We provide comprehensive noise and vibration engineering solutions for marine vessels and critical onboard systems, supporting naval, commercial, and marine engineering applications. Our expertise spans measurement, testing, analysis, diagnostics, and engineering consultancy to help assess dynamic behaviour, acoustic performance, structural integrity, and overall onboard operating conditions.

​

Through a combination of advanced measurement techniques, engineering analysis, and practical recommendations, we help identify sources of excessive noise and vibration, evaluate their impact on vessel performance and onboard environments, and develop effective solutions for improved reliability, safety, and comfort. Our services support applications ranging from complete vessels to individual marine systems and equipment, with testing and engineering practices aligned with applicable international, naval, and marine standards.
