Common Cause Failures Defense Approach

The common cause failures defense approach described below for oil and gas industry SIS focuses on the following fhree key aspecfs [11]  

To avoid introducing common cause failures during inspection and function testing processes 

To use the insight of failure causes for choosing efficienf mechanisms to defend against future occurrences of common cause failures 

To highlight common cause failures and their causes on the basis of failure reports 

This approach is based on six function testing and inspection tasks (i) scheduling (ii) preparation, execution, and restoration (iii) failure reporting (iv) failure analysis (v) implementation and (vi) validation and continuous improvements. Thus, the approach is composed of six tasks based on checklists and analytical methods, such as influence diagrams, cause-defense matrices, and operational sequence diagrams (OSD). The six tasks are described as follows [11]
