Work through the deciding factors and analysis on over-pressure protection on inlet design around API 521. The process of Process Hazard Analysis (PHA), Layer of Protection Analysis (LOPA), and the technology selection: HIPPS vs. PSV’s. HIPPS are High Integrity Pressure Protection Systems designed to supplant over-pressure protection. PSV’s are purely mechanical methods of over-pressure protection. Different levels of Cost, Safety, and Integrity must be evaluated when making technology selections.
