The M/E hydraulic lateral supporting device can change the intrinsic frequency of the engine when resonance occurs during normal operation. The M/E hydraulic lateral supporting device protects the engine, and slows degradation of the hull caused by loading and unloading.
M/E hydraulic lateral supporting devices are used in WARTSILA main engines. Specific models can be selected according to the parameters recommended by the main engine factory.
