Hye all. Is there stated anywhere i.e. international standard or best practise where all relief valve in plant must go periodically audit/check (i.e. every 3 years must have 1 overall audit in term of adequacy)?

Inspection included safety device for that particular equipment? Does they do the adequacy audit for that safety device? Here in malaysia some of the plant do the overall adequacy check using software (iPrism) by farris

Hi .

During Shut down or turn around all the devices are removed and inspected by 3rd party . Regular inspections are performed by maintenance and safety department .

Hi ,

My understanding is that you need certified people to perform the task , this means recognized by authorities .

In France I had in house qualified inspector .

Being in Asia for 19 years now , I get use to see what I described in my first answer , probably size of the plant should be considered .

It's plant size and timing dependent.  On a yearly basis, a small plant may not keep 1 man busy doing relief device PMI.  A large plant may need several.  Then, at plant turnaround, you need an army.

I'm not sure any international code discuss about the period. It's likely relate to each company policy. Two years ago, I've been involved to asses Flaring and Relieving system for all old plants owned by one of US biggest oil company.

I have found some figure from my colleague, his plant make overall check-up for every 5 years but not mandatory. But for every modification work / plant change shall have a study for the modification involve relief valve system.

Farid, it seems you are asking about documentation review only, and not hardware periodic inspection and testing?  If so, I don't think there is a recognized standard that speaks to a requirement.  If there is, I'd like to know too.  I have heard companies that go 5 years, 10 years, and a lot expect the Management of Change requirements to keep their reliefs up to date.

 

After 38 years, I know this is a area that can slowly get out of control, so a periodic requirement would be good.  Management does not like to spend $ they don't have to.

Yes. More to documentation check. Not hardware. They have to re check/re-visit on the credible case on that particular psv, the governing case..does it remain same or change. I will share the snapshot later
