Quick Facts

Summary

At Damen, many efforts are put in getting silent and comfortable ships. In the design stage sound level predictions are made to judge the feasibility of the design. This of course asks for accurate prediction methods.

Aspects covered in these prediction methods are:

  • The prediction of structure borne as well as airborne excitation levels of diesel engines, gearboxes, generator sets, propellers, etc.
  • Predicting the dynamic response of the ship structure, such as the input mobility of the engine foundation and the transfer of vibrations through the ship structure.
  • Prediction of attenuations due to acoustic countermeasures, such as resilient mountings, floating floors, visco-elastic damping, additional absorption, etc.
  • Prediction of radiation of lining and absorption of the sound levels in the cabins.

Prediction methods always needs validation by means of measurements. For this purpose, use is made of advanced measurement equipment.

Tasks & Responsibilities 

As an graduate at Damen, you will face several aspects in the field of sound and vibrations. It’s not only theory or practice, but the combination of theory with practice that leads to the best results.

Potential graduation projects can be:

  • Dynamic stiffness of stonewool and glasswool used in floating floors (Measurements and predictions)
  • Development of a semi-empirical prediction model for diesel engine airborne sound levels, structure-borne source levels and exhaust sound levels
  • Prediction model for HVAC sound levels in accommodation
