Safety-instrumented systems (SIS) are used extensively in the hydrocarbon processing industry to protect against hazardous events. Managing the Defeat of Safety Instrumented System Trips and Alarms is the latest position paper to be published by Marsh's Energy Engineering Team, setting out best practice techniques.

A system for managing the defeat of SIS trips and alarms should be robust enough to cater for all eventualities. Read our latest Engineering report, Managing the Defeat of Safety Instrumented System Trips and Alarms, for details on how to best manage this process.
