Abstract

The key purpose of asset integrity inspection is to protect human being, environment, animals and business by preventing costly asset failures and hazardous leaks by enhancing inspection reliability, effectiveness, spirit of asset condition monitoring and ultimately boosting up the probability of detection (PoD) of various types of defect. I believe that safety is a state of mind and management perception. NDE procedures and selected application techniques need to be always 100% focused on “what, why and how we want to inspect?” and over and above to be on the top of 100% HSE governance. This paper wants to discuss the ill effect on some old house heritage strategy and practice by many Oil & Gas operators / refiners / other Business Areas on execution and misuse of local spot UT during in-service inspection of process plant assets. This paper will try to highlight and resolve the conflict of interest of many operators on application intent between point spot UT and Scan UT during in-service inspection of operating plant asset. As asset integrity management is all about intelligent housekeeping of assets, we should not work on GIGO (Garbage IN-Garbage OUT) mode but should deploy sense full and meaningful NDE governance model. The issue may look simple but has dire consequences on plant operations, business integrity and continuity.
