How to determine the realibiliy of one equipment/machine?

Soledad ·
Hello everyone, thank you in advance for your help, I need to know if it is possible to estimate the realiability of one production line which has 10 different equipments (if one equipment fails the whole line stops), each equipment is different, I have the failure data of the last 12 months of the line (TBF and TTR). My professor asked to determine the reliability of the line per month, is it possible to determine the reliability with the information I have? Also, can I determine the...

Calculate per unit. Since they are in series adding your failure rates/probabilities will give line failure rate. If your rates are low you need not bother calculating the simultaneous failurere case so its just P(A)+P(B) and need not calculate P(A)P(B) and subtract which could get real messy with 10 units.

Also if your failure rates are low you may have to use more of a Bayesian methodology to do the calculation. Or since everything is in series if you just have overall downtime data you may only be able to use that. Using outright failure data is not always necessarily that useful because some failures may not cause downtime (noncritical failures, RTF candidates).

I guess no standard code for that but you can get PM for different rotary eqpt from their respective OEM manuals. So can start from there.

Troubleshooting Guide For Rotating Equipment

Lucman ·
Hi All, Can anyone please share with me any book/guide which contains all possible faults, how to diagnose/troubleshoot them and their rectification for rotating equipment? I fully understand that OEM manuals often have this information, but that normally does not cover all possible faults and their troubleshooting. Thank you for your help and appreciate your inputs. Regards, Lucman

Unfortunately what John and Shurafa are saying is true. Each type of equipment has it own unique failure modes that encompasses the design of the machine, the duty cycle, criticality of the machine and any process parameters. FMEA is in order for any critical equipment that you are responsible for. Too cut down on the work you group equipment together, fans/pumps/gearboxes etc. and than look at the particulars. There are templates out there. In the power business where I toil EPRI has a...

Re: standard practical procedure

Michael Meehan, CMRP, CRL ·
The maintenance required is going to depend on the service (light, medium, rough/corrosive), the duty cycle (intermittent, continuous, etc), and the equipment design (rolling element or plain bearings, pumps with packing or mechanical seals, vertical or horizontal motors, oil or grease lubrication, etc), so a generic guide to maintenance is all but impossible. As an earlier comment noted, start with OEM guidelines to begin with. Your next two steps should be to perform a Criticality...

Frequency of rotation for installed spare equipment

DHarberts ·
We have several instances in our facility where we have an "installed spare". I believe it would be a best practice to rotate them into operation on some frequency. I would imagine that the frequency would vary depending on the equipment and process but I am struggling to convince the operations group to begin this practice. What are the current practices through out industry and what is everyone's experience with this?

Re: Frequency of rotation for installed spare equipment

Richard Heiden ·
You will never get full consensus on this topic and I am sure you can search for some similar threads in this forum. Some believe you should not rotate on-line and standby equipment but run them as primary and backup and only run the backup for test runs on a periodic frequency. Some will advocate to run a primary most of the time but run the standby on-line for short periods on a specific frequency and others (myself included) will advocate for doing even rotations. At our power plant most...

availabilty forecasting

Hi dear all! I trust you are well. does anyone have an idea on how to forecast availability for a fleet of equipment ( truck, loaders, etc). I am looking for a standard procedure to estimate the availability over a long period ( one year) of mining equipement. regards

Re: availabilty forecasting

Shurafa ·
A general answer for a general question. Create a model for the system and assign the availability of each element to calculate the overall availability based on the relationships between each element and the rest of the system. Simplified example: Four cooling water pumps that work in active parallel with 34% of the total required flow provided by each pump. So, the system needs 3 oo 4 pumps at any time of the year to meet the target production requirements. Assume these pumps take a month...

Asset Hierarchy

Jim Perpinan ·
We are reshuffling the deck on our equipment groups within an industrial setting of a power plant and I am looking for any standards or industrial requirements to create an equipment Hierarchy to start with. So far I have a yes, on a equipment hierarchy by "Systems" that starts by highest asset value/cost and work down (on drill down). But I am aware of other hierarchy but need to get my hands on a few to test out. this will be going into a EAMS system. Any refinery templates out there?

Re: Asset Hierarchy

VinMan ·
Great to hear that Jim. ISO 14224 is more relevant to Oil and Gas Industry but is more universal in nature to be applied in other industry verticals. Wish you the best for your journey to organise the asset hierarchy. Shout out to me in case you need help me with the processes and templates.

Re: Asset Hierarchy

Jim Perpinan ·
Thank you, Vinman I have seen a lot of Uniformat II being used for smaller plants but its just not valid for a plant system because we do not use 90% of the hierarchy. This ISO 14224 seems to cover the bases and more.

Re: Asset Hierarchy

VinMan ·
Jim. ISO 14224 can provide you a good structure to see how the failure codes and hierarchy can be organised. Emerson's MRG Consulting also has a great value offering which can help you organise to validate the Master Equipment List followed Functional Locations/Area and then upload them into your CMMS. Let me know if you would like to know more about it. Cheers
