Emergency Shutdown system ESD

The main task of the Emergency Shutdown system ESD is to secure the shutdown function and control of specified devices and signaling of alarm in case of gas detedtion or other situations potentially dangerous for a ship equipped with LNG fuelled main and auxiliary propolusion.

In case of emergency, depending on its cause, the system interacts with a suitable algorithm for each device by:

Switch off:
–– Specified switchboard section eg. ventilation supply section
–– Main engine or auxiliary engine
–– UPS power supplier which supply specified devices

Control:
–– Fuel system shut off valves

Indication:
–– Alarm states on ESD system alarm panel
–– Alarm states to engine room monitoring system
–– ESD system switchboard self-diagnostic signals to engine room monitoring system

The ESD system is a redundant system. In case of single PLC or operator panel failure, the control task is automatically switched to second PLC. The control changeover is driven uninterrupted.

Each measuring input channel has a failure self-diagnosis of mesure sensor and measurement line cable

Marine-Electronics.eu provides the opportunity to develop a system both for newly built vessels as well as a retro-fits of old systems . We also provide service and maintenance of existing systems.
