15.2.2 Resilient mounting
In order to reduce vibrations and structure borne noise, main engines can be resiliently mounted
on rubber elements. The transmission of forces emitted by the engine is 10-20% when using
resilient mounting. For resiliently mounted engines a speed range of 500-750 rpm is generally
available.
