This E-Course defines how Safety and Environmental Critical Elements (SCE) are identified and the methodology for Performance Standards development to ensure that SCEs are suitable for their required function and maintained in a condition so that they will continue to perform their required function.

COMPANY shall update the SCEs register and define the Measuring Points based on Performance Requirements, Means of Assurance and Verification Schemes.

The objectives are as follows:

• To comply with the international regulations about the Safety and Environment Critical Elements management

• To capture best practice in the preparation performance standards;

• To contribute to the Technical Integrity assurance process whereby SCEs identified through scenario based risk assessment

A key part of SCE Integrity Management is the identification and management of Safety Critical Barriers (SCB). Bow-Tie analysis is required to identify the barriers protecting the personnel and assets from a major hazardous event. Operators will then focus efforts on identifying credible major accident hazards and then identifying SCEs which will prevent, control, mitigate and facilitate the safe evacuation from the identified hazards.

Because of the essential role of SCEs, assurance activities (maintenance, inspection and testing) must be put in place to continuously demonstrate that they remain fit for purpose during the whole life of the installations.

Other equipment having a similar role but which would not be active or operated in the occurrence of major accident hazards will not be considered as SCEs. This does not mean they will not be submitted to appropriate maintenance, inspection or testing as they may be important to field operations activities.
