How hard can it be? I’ve heard from several (unnamed) analysts that because they have access to an FEA program and have successfully applied FEA in other fields, that FEA for pressure vessels should be a snap. What is it about FEA for pressure vessels that makes it unique? I was recently discussing with another […]
In the past ten years, there have been a few oil storage tank annular plate failures due to soil side corrosion and fatigue loading (filling and emptying) which has led to large spills. The corrosion tends to be localized in a groove fashion and the size of the flaw could vary from 3 feet to […]
Risk based inspection (RBI) is a powerful tool to identify and manage mechanical integrity risks in fixed equipment and piping but is only one part of a robust reliability program. RBI informs inspection decision making on where, when and how to inspect most of equipment but is frequently misinterpreted as a “Silver Bullet” that covers […]
Where will crane mats be in 10 years, 20 years, 50 years? It takes approximately 90 years to grow a 12-inch by 12-inch oak timber twenty feet long. High quality hardwood timbers are becoming harder to find. This is widely known but rarely discussed. The shortage of wood timbers is a national problem. Timber Mats […]
There are a variety of conditions an in-service component (e.g. vessel, tank, piping) can be found in. The purpose of Fitness-for-Service (FFS) is to evaluate the integrity of an in-service component given a certain degraded condition and rate it for future service considering potential for any additional degradation. A degraded condition does not have to […]
Using the right software tool can save time and improve results of Risk Based Work Selection (RBWS) which is a standalone work process aimed at optimizing turnaround (TA) work scopes. RBWS uses risk assessments to determine if individual worklist items are justified by Health, Safety, & Environmental Risks or Financial Risks. Significant reductions in turnaround […]
A few years ago I conducted what might be the world’s cheapest, fastest and most cost effective due diligence study ever done. This study took one hour and cost the client about $500. I was approached by two new members of a well-recognized financial institution. They were assigned to evaluate opportunities to capture low cost […]
On December 29, 1972 one the Nation’s worst airline accidents occurred as Eastern Air Lines Flight 401 crashed into the Florida Everglades killing 101 of the passengers and crew. A National Transportation Safety Board (NTSB) investigation attributed the cause of the crash to crew distraction. While on approach, the crew noted that a landing gear […]
Reducing Loss of Primary Containment (LOPC’s) or commonly referred to as “leaks” in a refinery is a key factor to improve reliability. Historically, most refiners reduced the high consequence leaks to avoid major incidents; however, lower consequence related leaks were not given high priority. Today high reliability is required, and reduction of all leaks is […]
The API Inspection Codes were originally based on failure prevention and did not consider the consequences of failure or potential damage mechanisms. Risk-based inspection (RBI) assessments result in an equipment risk ranking based on the probability of failure (a leak occurring) and the consequence associated with that leak. Applied properly, RBI provides the benefit of […]
