Your Reliability Engineering Professional Development Site
Robots are developed to address a problem. For example, automating a production line. To achieve this goal, a multidiscipline engineering team is required.
The question is which engineering discipline should I study? I suggest you get a degree in System Engineering. This paper will explain why.

Example ACE 3T (Target-Tolerance-Test) Procedure with Reliability Standards: Machine performance is totally dependent on human beings. To address the problem of human error causing equipment failure, an Accuracy Controlled Enterprise sets best practice quality standards and uses 3T Target-Tolerance-Test work task quality control that assures high quality workmanship for high reliability results. Their work procedures are standardised so everyone follows the same methods to produce the same results, their training teaches people how to do craftsmanship work that creates outstandingly reliable plant and machinery. They create the reliability they want and as a result achieve operational excellence.

In this episode, we talk about what a Failure Mode is and why Failure Modes are so important to equipment Reliability. As responsible custodians, it’s up to us to identify the plausible Failure Modes that could occur so that we can figure out if and how we should manage each one. If we don’t, it can end up in disaster.

We have been burning wood since days of the caveman. But did you know that wood can also explode?
Logs of wood will not explode but fine dust can lead to a fire and explosion. Let us see why.

In the 15th century, the English Royal Navy did not exist as a standing force. When needed, the Royal Navy was temporarily assembled using rented merchant ships. Henry VIII expanded England’s fleet from a handful of small converted merchant ships to a force of 30 purpose-built warships. He established government dockyards, the Admiralty, and the Navy Board. Starting in 1546, the Navy Board was a permanent part of the government.
Warships owned by the government had no other purpose and suddenly gave the government a new kind of asset to manage.

Almost daily, we hear of some problem in the supply chain. A few weeks ago, a container ship got stuck in the Suez Canal and hundreds of ships were backed up with no place to go. As well, original equipment manufacturers in Europe missed critical parts because of their Just in Time delivery practices.

Road Tanker Design For Fast Unloading And Onshore Pump Drain Tank. To completely empty a road tanker the compartments need to be designed to have a sump that permits total drain-out of the liquid from the lowest point. If a pump is mounted on the trailer, it is best mounted under the trailer. Where a pump is mounted on the tray or fenders it will cavitate at low tanker liquid levels. For an onshore unloading pump installation it is best to install a buffer tank between the tanker and onshore pump to let the road tanker completely drain-out before the pump starts cavitating. Tanker load-out pumps must have a very low net positive suction head requirement.

Everyone working in a decision-making role has at least an intuitive understanding of the concept of opportunity costs-the value of the thing you didn’t choose. Simply stated, when you say ‘Yes’ to one thing, you simultaneously say ‘No’ to everything else you could have chosen instead. And those things to which you say ‘No’ have a value that you’re relinquishing. When I was a teenager, I heard an older gentleman quip, “When I said ‘I do’ to my wife, I was also saying ‘I don’t’ to all the other girls out there”. That man understood opportunity cost.

Methane being extremely flammable, the fire and gas detection (FGD) system in LNG facilities should be capable of early detection of flammable gas leading to shutdown/isolation and depressurization.

Ask yourself, when teams work very well together, what are the positive characteristics of the team leader? When teams are dysfunctional, and have poor outcomes, what skills of the leader need to be improved?
Giving proper feedback is a great way to help a colleague improve FMEA facilitation skills. Carefully listening to feedback from a colleague is an important way to improve one’s own FMEA facilitation skills. Both are aided by understanding and using facilitation quality objectives. [Read more…]
In February 2021, the Organization for Economic Cooperation and Development (OECD) published an Enterprise Risk Management Maturity Model. This model is designed for Tax Administration Agencies. It is the culmination of work that began in 2018. This work was designed to develop stand-alone maturity models for a broad range of organizational activities. One of which was Enterprise Risk Management. This piece examines this model and discusses how such models are being used by government elsewhere.

This simple example explains how to calculate the failure rate of parts, known as the Hazard Rate, using a drinking glass. Historic records, like maintenance, operating, supply chain, and financial information, are accessed to understand the situation being analyzed and gather modelling data. Once all necessary information is collected and the situation is investigated, then proposals to address and solve the problems causing and permitting the failure to happen are selected and a business case is developed.

In this episode, we answer two questions: 1) What is Reliability? 2) How do we get the Reliability we need from our machines? Nancy also discusses how we design our Reliability both literally and figuratively. The quality of our proactive maintenance and Default Strategies largely determines the Reliability we get from our equipment. Inherent Reliability is explained.
