Recommended design of the generating set seating (3V46L0295d, DAAE020067a)
Rubber mounts
The generating set is mounted on conical resilient mounts, which are designed to withstand both compression
and shear loads. In addition the mounts are equipped with an internal buffer to limit the movements of the
generating set due to ship motions. Hence, no additional side or end buffers are required.
The rubber in the mounts is natural rubber and it must therefore be protected from oil, oily water and fuel.
The mounts should be evenly loaded, when the generating set is resting on the mounts. The maximum
permissible variation in compression between mounts is 2.0 mm. If necessary, chocks or shims should be
used to compensate for local tolerances. Only one shim is permitted under each mount.
The transmission of forces emitted by the engine is 10 -20% when using conical mounts. For the foundation
design, see drawing 3V46L0295 (in-line engines) and 3V46L0294 (V-engines).
