MARMOT Seismic Monitoring and Trip System

SYSCOM Seismic Monitoring for Critical Nuclear Power and LNG Plants


The SYSCOM MARMOT Seismic Monitoring and Trip System provides a comprehensive approach to the increasing safety demand in high value but vulnerable sites which are at risk of catastrophic failure due seismic loads during earthquakes . Typical sites monitored include Nuclear Power Plants, Nuclear Storage Facilities, Liquefied Natural Gas Storage (LNG) sites, Gas Turbine Power Plants and Chemical Process Plants

The Trip System may be set to automatically initiate a shutdown procedure for critical machines immediately upon exceedance of the shut-down alarm threshold. The shutdown alarm is set based upon exceedance of the threshold by multiple ground vibration units.
