Seasoned and knowledgeable inspectors are becoming harder and harder to keep. But using some of the industry documents in a smart way, inspectors with less experience can perform like an inspector with many more years of experience and even develop a great materials specialty with practice.

The Joint Industry Project for Risk-Based Inspection (RBI JIP) was initiated and managed by API within the refining and petrochemical industry in 1992. The work from the JIP resulted in two publications, API 580 Risk-Based Inspection released in 2002 and API 581 Base Resource Document - Risk-Based Inspection originally released in 1996. The concept behind these publications was for API 580 to introduce the principles and present minimum general guidelines for RBI while API 581 was to provide quantitative RBI methods.

The API Risk-Based Inspection (API RBI) methodology has been used in the Refining and Petrochemical industries to manage the overall risk of a plant since the mid-1990's as a methodology for focusing inspection efforts on the process equipment with the highest risk. API RBI provides the basis for making informed decisions on inspection frequency, the extent of inspection, and the most suitable type of NDE. In most processing plants, a large percent (80-90%) of the total unit risk will be concentrated in a relatively small percentage (10-20%) of the equipment.

Risk-Based Inspection (RBI) is an emerging technology available to plant engineers and managers as theyapply risk directed activities to prioritize work and available resources for equipment management. This paper describes the learning of highly experienced RBI users, sharing results of implementation in their plants. The advantages of making and documenting reasonable assumptions will be explored.

Risk-Based Inspection (RBI) is an emerging technology available to plant engineers and managers as they apply risk directed activities to prioritize work and available resources for equipment management. This paper describes the learning of highly experienced RBI users, sharing results of implementation in their plants. The advantages of making and documenting reasonable assumptions will be explored. Additional benefits of the program will be shared, such as streamlined process reliability studies where RBI information can significantly impact time required for completion. Results of using the API RBI methodology for storage tank analyses will also be presented. The presenters have a combined refinery experience of over 40 years and RBI experience of over 10 years with responsibility for over 20,000 pressure vessels and overall responsibility for equipment integrity in two large refineries.

Damage of carbon steel pressure vessels due to various in-service damage mechanisms continues to be a serious concern in the refining and petrochemical industries. A survey conducted in 1990 by the NACE T-8-16 Work Group to determine the nature and extent of cracking problems in wet H2S refinery environments showed that there was insufficient information reported about the type of cracking found to correlate cracking incidence with cracking mechanisms. Most of the inspections for cracking reported were detected during internal inspection using Wet Fluorescent Magnetic Particle Testing (WFMPT). As a result, it was concluded that in addition to the service related cracks reported, a number of "cracks" detected were the result of original fabrication, repair or alteration of the pressure vessels.

This is Part II of a series of reliability of coke drums. Part I discussed some of the causes of bulging and cracking in coke drums. Here, the effect of operation on damage will be covered, along with possible solutions for increasing drum life and decreasing the probability of an unscheduled shutdown.

Petroleum coke production is an important source of revenue for many refineries. While coking units were initially constructed to deal with a waste product, these units are now of significant economic value.
