Ensuring the achievable and reasonable design targets for on-board machinery and structures at the design stage can guarantee successful constructions which meet building specifications and comfortable environments in ships and offshore structures. Our experienced engineers supply the following consulting services to owners and builders for noise, vibration and underwater radiated noise performances.
From dynamic stiffness estimation to forced vibration response analysis, precise and effective vibration analysis using 3D FEM can be carried out depending on our customers’ demands. We have experiences over 80 vibration projects for ships and offshore structures since 2000 and can help customers to design and obtain high quality low vibration environments.
CreaTech considers all noise propagation mechanisms in noise analysis using 3D computation S/W and design information. Predicted noise levels at the interested areas are compared with the related noise criteria, and economic & efficient countermeasure methods are provided based on the calculation results if necessary. The detailed information for noise analysis is listed below
For research vessels and naval ships, the URN (Underwater Radiated Noise) performance has become to be very important as an aspect of the successful research & accomplishment of military mission. Our URN analysis considering all of the URN mechanisms including the vibration and noise produced from on-board machinery, structural characteristics of hull and direct underwater noise induced by the propeller can guarantee the successful building of customer’s silent vessel.
CreaTech’s engineers with rich experiences in the various industrial fields and possessing the precision equipment will conduct rigorous assessment, measurement and diagnosis for troublesome vibration/noise. In addition, we will present the most economical and efficient countermeasures based on the measurement results
