Friedrichshafen, March 19, 2008. The Tognum subsidiary MTU Friedrichshafen has signed a contract on the exclusive distribution of active engine mountings with the companies Paulstra and Stop-Choc. The jointly developed system, which MTU has successfully trialed on test benches and in ships, significantly reduces the structure-borne noise emitted by diesel engines. This innovative concept of active mountings has been developed through to product maturity for yachts and naval ships. With this cooperation, MTU Friedrichshafen is expanding its core competencies in the system business.

MTU engines are installed on special rubber mountings as standard equipment to reduce the transmission of structure-borne noise to the ship’s hull. The new active mountings support the passive rubber mountings and make their noise reduction far more effective. The active mountings are based on the noise-cancellation principle: they create sound waves with the same amplitude and the opposite polarity to the original structure-borne waves of the engine. In this way, noise and anti-noise cancel each other out to a large extent. With this technology, which is being applied to marine diesel engines for the first time, MTU can offer its customers tailored system solutions for noise reduction on the basis of passive and active systems.
