Layer of Protection Analysis (Technical Tools/Mechanical Integrity/Risk Management Tools/Layer of Protection Analysis)

A semi-quantitative analysis of the risk of a scenario; each scenario has a consequence with its associated severity and one initiating event with its associated frequency; IPLs are evaluated for applicable risk reduction; additional layers, such as SIFs , can be added to meet a risk target.
