Resumen
In the operational context of industrial processes, alarm, by definition, is a warning to
the operator that an action with limited time to run is required, while the event is a change of
state information, which does not require action by the operator, therefore should not be
advertised, and only stored for analysis of maintenance, incidents and used for signaling /
monitoring (EEMUA, 2007). However, alarms and events are often confused and improperly
configured similarly by developers of automation systems. This practice results in a high
amount of pseudo-alarms during the operation of industrial processes. The high number of
alarms is a major obstacle to improving operational efficiency, making it difficult to identify
problems and increasing the time to respond to abnormalities. The main consequences of this
scenario are the increased risk to personal safety, facilities, environment deterioration and loss
of production. The aim of this paper is to present a philosophy for setting up a system of
supervision and control, developed with the aim of reducing the amount of pseudo-alarms and
increase reliability of the information that the system provides. A real case study was
conducted in the automation system of the offshore production of hydrocarbons from
Petrobras in Rio Grande do Norte, in order to validate the application of this new
methodology. The work followed the premises of the tool presented in ISA SP18.2. 2009,
called "life cycle alarm . After the implementation of methodology there was a significant
reduction in the number of alarms
