Equipment Operators face hundreds of work list items while planning for scheduled maintenance events. For each item the owner must make a decision on whether to repair or replace the equipment to resolve the deficiency. In some circumstances, owners are unable to come up with a cost effective repair solution so they default to the […]
Reliable operations is a key business objective for nearly every manufacturing plant due to global economic pressures and increasing Process Safety Management (PSM) requirements. Pacesetter sites that have been successful in achieving long-term reliability are characterized by Business Units empowered and accountable to meet their reliability targets. Structured work processes, with specialist support, provide the […]
Note: This blog is a continuation from the previous article from Becht Engineering, “Shaft Fatigue Failures – Part I”. It is suggested that the reader review “Shaft Fatigue Failures – Part I” before proceeding with this article. Click Here to view Part I. Before getting into the calculation methods, first a quick refresher on high […]
Many years ago when I first started my career in a rotating equipment maintenance organization, I was spending the day with a senior metallurgist, which was part of my orientation process as a new technical employee. He was well known to not have the best “bedside manner” and it was clear he was not thrilled […]
Achieving “State Special” designation for a pressure vessel can require a fair amount of effort in documentation development. This process is warranted – for example – when a company wants to move a pressure vessel from one facility for operation in a facility located in another state, or when they purchase a used vessel located […]
Refrigerated Liquefied Storage Tanks have been used for over 60 years in the industry. A significant number of these tanks store liquefied Propane and Butane, Ethylene and LNG and Ammonia. The stored fluids are at atmospheric pressures with temperatures which range from -45 F to -270 Failures of refrigerated tanks have been quite infrequent over […]
There are numerous challenges that Inspectors and Reliability Engineers face when developing Risk Based Asset Integrity Plans, such as: Identifying the applicable Damage Mechanisms Picking the correct Failure Mode(s) Determining the Probability of Failure Deciding how to mitigate risks to acceptable levels Industry documents give some guidance (i.e. API-571, API-580) but not the whole picture. […]
The world of reliability is shifting from a calendar based approach to a smarter, risk-based approach in the hydrocarbon production and refining world. The leadership teams are now expecting a risk-based program in place for minimizing the HSE (Health, Safety and Environment) and economic consequences as much as possible. Some states have mandated the use […]
Every Refinery whether small or big, isolated or a part of a larger group generally has practices to improve reliability of operations. However, refineries who are known to be world class performers have well defined Reliability Management Systems (RMS) which focus on improving equipment reliability for piping, pressure vessels, rotating equipment, electrical distribution system, instrumentation […]
Ingersoll Rand Cone Oil Seals Compressor process shaft end seals are designed to seal the rotating assembly in the stationary compressor case to prevent the process gas in the compressor from escaping to the atmosphere and to prevent the atmosphere from getting into the process gas. Shaft end oil seals, as compared to the relatively […]
