Expert solutions for acoustic engineering and optimization of systems
Enabling quiet system operations through innovative acoustic engineering
Noise and vibration compliance for marine systems
Marine components such as engines, propulsion units, gearboxes, couplings, and pumps often need to comply with stringent structure-borne noise (SBN) and airborne noise (ABN) criteria prior to vessel integration.
Does your system also need to comply with such an acoustic specification? Our experts at JASCO interpret the noise and vibration requirements, investigate the system’s potential to meet the requirement and assist in the development, adaptation or production process.
Certified noise and vibration measurements are performed by our engineers during Factory Acceptance Testing (FAT) to ensure full compliance with applicable standards.
Example cases
SBN reduction of propulsion machinery
Modal analysis of engine, alternator, and skid. Design of foundation, selection of elastic elements, and shaft coupling.
Double elastic mounting system for genset
Modal analysis of system, design of intermediate frame, selection and arrangement of elastic elements.
Noise reduction for electric motors
Investigation of electric noise sources regarding frequency and level, impact of VFD, effect analysis on the ship, and solution recommendations.
