This week I ‘d like to walk through the quick and easy process to create a new custom list in our TapRooT® VI software.
Technically Speaking is a weekly series that highlights various aspects of the TapRooT® VI software and occasionally includes a little Help Desk humor.
Remember, just because it’s technical, doesn’t mean it has to be complicated!
I remember my mom telling me to “wash my hands before supper”. Something that we all should know how to do, yet vitally important in the medical community.
How hard can it be to wash your hands? If I told you to “Wash your hands before changing that bandage,” how would you do it? What soap would you use? How do you dry your hands afterwards? At what point in the procedure do I actually have to wash your hands? As you can see, there are lots of opportunity to make a mistake and cause a problem, unless you have the answers to these questions.
Hand Hygiene: A Handbook for Medical Professionals is an about-to-be-released book on how to properly hand infection control in a variety of circumstances. It puts all of these lessons learned into a single reference for a professional to figure out the right way (and the wrong way) to prevent the spread of infections between patients.
Here’s a summary for reported sentinel events for the 2nd quarter of this year, compiled by The Joint Commission. It also compares some of the data against previous years.
It is almost impossible to make accurate comparisons on this data, since all reports are voluntary and, as stated in the report:
“Data Limitations: The reporting of most sentinel events to The Joint Commission is voluntary and represents only a small proportion of actual events. Therefore, these data are not an epidemiologic data set and no conclusions should be drawn about the actual relative frequency of events or trends in events over time. ”
Without knowing who is reporting, who is not reporting, how these numbers are compiled or arrived at, how the problem types are assigned, etc., I’m having a tough time viewing the data in an objective light.
While the data is interesting, I’m not sure how this data is used. Can anyone give me an example of how the data in this summary might be used?
The following is a IOPG Safety Alert from the International Association of Oil & Gas Producers…
IOGP SAFETY ALERT
CORROSION COUPON PLUG EJECTED FROM PRESSURISED PIPELINE
Personnel accountable or responsible for pipelines and piping fitted with corrosion coupons.
A routine corrosion coupon retrieval operation was being conducted on a 28” crude oil pipeline. Two retrieval technicians were located in a below ground access pit, to perform the operation. The operation involved removal of the corrosion coupon carrier ‘plug’ from its threaded 2” access fitting on the pipeline. The plug was ejected at high velocity from the access fitting (pipeline pressure 103 bar), during the operation to ease the plug using a ring spanner to a maximum of ¼ turn (as per procedure) and before the service valve and retrieval tool were installed. A high volume of crude oil spilled from the pipeline via the access fitting. Fortunately, the two technicians escaped the access pit without injury from the plug projectile or crude oil release.
What Went Wrong?
The Venture is still in the process of conducting the incident investigation. Based on their findings to date, the most probable cause is that the threads of the access fitting were worn down to such an extent, that they were unable to restrain the plug upon minor disturbance (the ¼ turn of the plug).
- The access fitting was installed during pipeline construction in 1987. It is estimated to have been subject to over 140 coupon retrieval and installation cycles.
- Bottom-of-pipeline debris can cause galling of threads on stainless steel plugs, which in turn can damage the threads of carbon steel access fittings.
- The repair (chasing) of worn threads on access fittings is performed using an original equipment manufacturer supplied thread tap assembly service tool.
- In the presence of bottom-of-pipeline debris and thread damage, the repetitive removal of internal thread material, can lead to ever smaller contact surfaces, increasing contact stress, increasing wear rates and/or galling.
- Smaller thread contact surfaces reduce the ability of the access fittings to restrain plugs.
- In this incident, the original equipment manufacturer supplied thread tap assembly service tool had been used routinely for every plug coupon retrieval and installation cycle without the use of flushing oil to remove debris from the threads.
Corrective Actions and Recommendations:
Lessons Learned –
- As yet, there is no standard method to determine internal thread condition of on-line corrosion probe/coupon original equipment manufacturer access fittings. Thread condition is not easily inspected.
- The risk posed by long term use of thread tap assembly service tools on access fittings, has not been previously identified.
Action taken in originating company –
Temporarily suspend all corrosion coupon retrieval operations on pressurised lines furnished with threaded access fittings in the 6 o’clock position (bottom of pipeline). This provides time to complete the investigation and complete work with the original equipment manufacturer to develop clear guidance on the maximum number of retrieval cycles.
- A subsequent notification will be issued based on the completed investigation and original equipment manufacturer tests*. In this alert any changes to guidance or maintenance routines (i.e. how and when these type operations can be recommenced) will be advised.
- The temporary suspension does not cover retrieval operations on lines which are depressurised.
* the use of ‘no go’ gauges for checking access fittings after every use of a thread tap assembly service tool or access fitting body seat reamer, is being explored.

Johannesburg, or Joburg as the locals call it, is an amazingly diverse city that goes unnoticed. It is said to be the world’s largest city not located directly on a water source, however, it is located on mineral rich land where the city’s source of gold and diamonds come from. It is also known as Africa’s economic powerhouse due to it being the largest economy of any metropolitan area in Sub-Saharan Africa. Not only that, it’s rich history with Apartheid and Nelson Mandela are what really make the country of South Africa an historical landmark. Visit Joburg and see what this massive city has to offer, including our TapRooT® 5-Day course.

When designing spacecraft, there is a humorous (yet amazingly accurate) list of laws to keep in mind to ensure you are not going down the wrong path when developing spacecraft and their associated systems. Akin’s Laws of Spacecraft Design are a set of well-known nuggets that can be adapted to everyday life. But the one that I want to mention here is Akin’s Law #1:
1. Engineering is done with numbers. Analysis without numbers is only an opinion.
When you are looking at your pumping systems, and trying to decide on the best maintenance or repair strategy for a particular pump failure, you may have several options. For example:
– Should I just replace the failed pump with another identical pump?
– Should I replace it with a more efficient design?
– Is the current pump optimized for the system design?
– What other options are available for this repair?
– Why did it fail in the first place?
Life Cycle Cost analysis can be done after almost any failure to help you decide on the best repair strategy. This analysis includes things like the costs of the initial purchase, installation and commissioning costs, energy and operation costs, and maintenance costs. You can perform a relatively accurate cost comparison for various repair / replacement options so that you can make an educated decision on the best course of action. Pump Life Cycle Costs: A Guide to LCC Analysis for Pumping Systems is the result of a collaboration between the Hydraulic Institute, Europump, and the US Department of Energy’s Office of Industrial Technologies (OIT). It is definitely worth a few minutes to read through this and get a basic understanding of how to calculate the LCC of a particular installation or repair.
There were a couple of take-aways for me, neither of which was particularly surprising, yet both of which are important to keep in mind:
- Energy consumption is often one of the larger cost elements and may dominate the LCC, especially if pumps are run more than 2000 hours per year
- The cost of unexpected downtime and lost production is a very significant item in the total LCC and can rival the energy costs and replacement parts costs in its impact.
Which drives home the importance of a good root cause analysis to ensure that your failures (and therefore your downtime) are minimized, as the costs of these failures can rapid skew the entire LCC analysis. Don’t live with repeat or avoidable failures.
