    Alarm Management

  • Dates



Alarm management packages can struggle to meet the needs of a full alarm lifecycle. In particular, users often conduct their Alarm Objective Analysis (AOA) process on a greenfield site well before the control system configuration has begun.


Typically many specialists are involved during the AOA process, both internal and external consultants such as Yokogawa VPS engineers. This is the key period when a large amount of information is created but, due to the lack of tools, much of this information is lost or buried in different documentation stores.


AMD fully supports the Management of Change (MOC) process by providing a number of features to store information into a centralized location and reduce the effort required to conduct each MOC cycle.


The Problem


Poor alarm management is one of the leading causes of downtime and has contributed to some of the worst recorded industrial accidents.


Changes to alarm limits through lack of alarm management can potentially lead to safety failures, lost production and equipment damage. Engineering time can also be lost due to poor or incorrect record keeping.


The Solution


Exaquantum/AMD (hereafter known as 'AMD') is Yokogawa's Master Alarm Database solution. Based on ANSI/ISA-18.2-2009 and EEMUA 191, AMD assists managers and supervisors in monitoring, assessing and auditing the behaviour of alarm setpoints as part of an alarm documentation and rationalization program.
