Maintenance tech tip

Reliable Process Control And Instrumentation - Use Redundancy.

 

This months tip comes from Mike Sondalini of www.lifetime-reliability.com

Each month you get at least one tip to improve the reliability of your control and instrumentation systems.

Redundancy (duplication) is a key factor to reliable, long-life, failure-free process control. The low cost of today's basic process sensory elements means that more than one item of instrumentation and circuitry can be installed for most applications.

A control circuit with duplicated temperature transmitters, duplicated level transmitters, duplicate flow transmitters, etc, and their associated electronics, monitoring and self-checking devices would have a high probability of delivering outstanding reliability.

The cost of duplicated instrumentation and control circuitry is negligible in situations where equipment failure will take life or livelihood.

There are very few situation in continuously operating plant, and even in batch plants, where the total production costs of a minor downtime incident would not easily pay for more highly reliable process control and instrumentation equipment.

If you're a plant or equipment designer, or a corporate accountant, let me advise you (as a person who has to live with the final consequences of production plant failures) that the few extra dollars it costs to provide control system redundancy and duplication will pay for itself many times over in the operating life of the business.

A simple example was a water head tank high up on a building, which provided constant pressure to a production process. The level control was a simple mercury float switch who's position opened and closed a solenoid valve on the water inlet pipe. One night the float switch leaked and sank to the bottom of the tank and did not turn off the water supply. The tank continued to overflow all night till someone saw a pool of water the next day.

During the repair a second float switch was installed into the circuit in parallel with the first. With two floats now monitoring the water level, the likelihood of both failing at the same time and not closing the solenoid was reduced to extremely low statistical levels.

The extra cost for a second mercury level switch, and its installation and wiring, was $200. The future costs saved from wasted water, breakdown maintenance, unplanned disruption to production and lost supervisory and management time, easily paid for the duplication and redundancy.

Do you see what happens when you use a duplication philosophy? You take the failure from a breakdown nightmare to a simple preventative maintenance routine. Suddenly it doesn't matter if you lose an instrument, the other is still operational. A repair is now something you can plan-in and do for little cost compared to a breakdown.

The inspection of the instrument's condition now becomes an operator daily shift routine. If a problem is seen a work order is raised and scheduled into a planned outage.

Don Fitchett of Feed Forward Publications goes one step further and suggests :

"You could wire both sensors into separate PLC inputs or relay, so if you don’t see both sensor inputs at the same time, a ‘sensor 1 or 2 out’ lamp lights-up.

This would save even more time by having one less stop on the operator’s daily inspection shift routine. With automated detection of sensor failure, a daily routing could now be moved to once a month on the PM schedule. Cost to add this to an existing PLC, zero. The cost to wire it up with relays would be about a couple hundred dollars."

By duplicating control and instrumentation equipment you have in fact saved the company a lot of money in the future!

Mike S.

Outsourcing pro and cons - Contract Maintenance or not?

 This month we have  a well written article on HR outsourcing pro and cons as it relates to maintenance contracts. The article was graciously donated by Torbjorn Idhammar is president of IDCON, a reliability and maintenance management consulting firm.

Some of the reason for outsourcing identified by Mr. Idhammar is variability in workload, temporary scheduled increase in workload, core business philosophy and lack of skills. Mr. Idhammar then gives us valuable advice when outsourcing in areas of incentive for the contractor to continuously perform better, equipment reliability and long term contracts.

I recommend you read Mr. Idhammar's article in our article section of this website. Contract Maintenance or not?

With regard to several recent press reports on the accidental release of hazardous or toxic chemical or gas clouds into the atmosphere, it should be noted that software is available to analyse and prevent these situations. BREEZE HAZ software includes several air dispersion models, as well as fire/explosion models. This provides for real time emergency response, HAZOP planning, Quantitative Risk Assessments (QRA's), and Environmental Impact Assessments (EIA's)etc, in line with regulatory requirements.

HR Extra:

Hi, Don Fitchett here. First of all I would like to let you know below is not a paid advertisement. Even though it may appear so. :>) 

I have traveled to many facilities over the years and ask most of them...

What kind of Kaizen program does your facility have?

The reply I receive the most is 'what is Kaizen?'. It never ceases to amaze me of how many do not know of a program that has such a high success history, takes little investment and provides such a great return on ones investment. So when I received the ad below from a group I subscribe to called NWLEAN, I just had to let our readers know.

(By the way, NWLEAN is another great learning resource which you can join the group by clicking on the link.)

I recommend you Visit www.gemba.com/Lean_Learning_Lab.htm and attend one of their workshops if you get the chance. At least visit their great website and learn how your company can profit from implementing a Kaizen program of your own.

The Human Side of Lean

The Idea Generator - Quick and Easy Kaizen

Imagine getting 100 to 1 payback on your investment! Add real improvement power to your Six Sigma and Lean Efforts. This powerful one-day workshop is your answer!

Seattle, WA, May 10

Norman Bodek introduced to America the Kaizen blitz, SMED, poka-yoke, TPM, QFD, Hoshin Kanri, and other Japanese business techniques. He now wants to introduce you to the real power behind these techniques. It's challenging and empowering all of your employees to solve the hundreds of small problems they face everyday at work. Instead of always telling your workers what to do, you now ask them to identify the problems, come up with their own solutions and implement those ideas themselves. You ask your employees to make their work easier and more interesting while at the same time reduce costs, improve safety, improve quality, improve customer service and also improve the process. Norman's latest book, co-authored with B. Tozawa, is The Idea Generator- Quick and Easy Kaizen.

The average employee in Japan implements two creative ideas per month. Dana Corp. and Technicolor Corp. both do this in America. The result is millions of dollars in savings. In fact, you can plan to save $3,000 per year per employee in savings. That is what is happening at Matsushia Electric (Panasonic). In Japan, the "quick and easy kaizen" concept is booming. You can expect the same explosion to take place in the United States - and soon!
