  1. Hi @Erik Hupje, Thanks for your response. I think it prudent to mention the number of start/stops will also have an effect on seal life, and with condition monitoring fitted, should negate the need for time base maintenance and prolong the service life between overhauls. The strategy for the least number of starts operating in a duty/st-by arrangement I think would prove to be the best for lower maintenance and downtime. I suppose the two issues to consider are uptime and costs. Alternate or duty/st-by policies both have their pro's and cons and in term of reliability for either depends on their operating context and age related failures would be evident for a machine that is running and a machine that is not. Cheers Derek
  2. Hi there, I was looking for peoples opinion on the duty/st-by arrangement for pump sets. I have not long started at a large petrochemical plant and to my surprise they do not do a periodic swap over of pumps as the Ops team have their “favourites”. I am now looking to convince them otherwise and introduce an Ops routine in the CMMS to try and push them to do it. My question is has anyone ever encountered this and how did you overcome it, and also what was your strategy? For me having two pump sets with the same run hours is not ideal and should have a lead/lag machine where the lag is only used in times of inspection, overhauls or breakdowns until the lead unit can be brought back online. Thanks Derek
  3. Are there any test examples with study questions available @Erik Hupje?
  4. Hi @Erik Hupje, Have you sat the CMRP examination, and if so, how did you prepare for it, just read through the books listed and test examples? Derek
  5. Hi @Erik Hupje, Many thanks for this. I already have the Reliability-Centered Maintenance by John Moubray, I bought it as my lecturer advised it was worth having. Re the certification, Reliability engineering is certainly the niche' engineering route I am keen to pursue further, although there are different interpretations of reliability, or asset engineer certainly in industry, where reliability can just mean the nuts and bolts and not data analytics, failure rate acquisition and root cause analysis. This is where I find myself at the moment as my role is predominantly "keeping the plant going" and not enough time to devise medium/long term reliability strategies. I know this has to be a management driven objective to change the culture of maintenance but it does take time and effort. I read a quote on reliability - "everyone thinks reliability is like safety, it's a great idea but not everyone does it" - Heinz Bloch. Although my employer is trying to build a reliability team at the moment, it is something I would like to be part of. I have been in my current role for a few months and I am keen to make changes where I can and improve the plant I look after and learn as much as I can from others and utilising technology. I have heard of CMRP certification and it is something I will likely pursue, but are there no UK based accreditations for maintenance and reliability? Thanks, brgs Derek
  6. Hi Eric, I am upstream, looking after a plant using propylene to make plastics. I studied Maintenance and reliability at university after being on the tools for a number of years and I was amazed how much I didn’t know. For instance, maintenance is taught as a science, statistics, machine failure modes, the physics of how machines operate and more importantly how they degrade and fail. So sites such as yours instantly peaked my interest. Are there any certification for reliability practitioners that you can recommend? Thanks Derek
  7. Hi, new to the forum, I have had the pleasure of working in various industries and now I find myself in the petrochemical sector. My current role is a Mechanical Asset Engineer, so I have taken a keen interest in Reliability and Maintenance.
