Consorzio Servizi Navali Industriali (CSNI Scarl) and Marinoni, European companies that specialize in flooring and fire prevention systems, are working on solutions to improve ship comfort. Their projects focus on reducing the noise that passes through deck structure into the cabins below and developing a new housing solution that reduces the height between decks.
The engineers looked at the ship’s structure with regard to reducing vibrations. There were hundreds of supports in the ship’s structure. Inserting an acoustical vibration dampening system at the base of the supports would dampen the vibrations and cut their flow.
The engineers will also identify and develop improvements for future ships. Such improvements will reduce structure weight, overall installation volume, and reduce construction and refitting time costs. This part focuses mostly on the hotel part of the ship.
The companies’ objective are to industrialize the system and pinpoint a configuration that can attain the highest dampening of the widest spectrum of vibro-acoustic frequencies, all while maintaining shipbuilding requirements.

Ecomass Technologies
Ecomass Technologies is the pioneer and technological groundbreaker in high density plastics, high density polymers, thermoplastic composite materials, and high density engineered thermoplastics. Its sales and engineering teams have helped commercial and government customers conquer physical property challenges by developing over 100 high gravity thermoplastic composite materials engineered for weighting, balancing, radiation shielding, and vibration dampening applications.
All materials have natural or resonance frequency. Energy waves, which have both frequency and amplitude, cause vibrations. When technicians and engineers can’t isolate and reduce energy at the source, they utilize dampening materials to reduces, restrict, or prevent oscillations and, thus, reduce energy.
Aircraft audio systems, sports and luxury automobiles industrialists, are just of the few who have successfully used Ecomass’s vibration dampening compounds to achieve their developmental goals.
All Ecomass Compounds meet the EU RoHS Directive, are 100% lead free, do not contain any U.S. EPA toxic or hazardous materials, and comply with Section 1502 of the Dodd-Frank Act.
Contact Ecomass today or see its website and complete one if its RFQ Forms to find out how you and/or your company might be able to use its compounds for vibration dampening or apply them to any other valuable use.
