Pressure Relief Valve Devices Frequency
Pressure Relief Valve Devices Frequency
(OP)
Hi Guys
I have been given the task to come up with a strategy for overhauling Relief Valve devices (PRV, TRV ect.) for a LNG facility. I have located and read the relevant regulations and guides in relations to setting the frequency period, however I am having some trouble applying it my situation
- this is a new facility - so I have no operational history
- regulations state that the max period is 5 years
So my question is, how do you break this down? Do you set a frequency period for each type of device or do you set the frequency period in regards to where it is located i.e LNG train, LNG storage ect.
Thanks!

I don't think there are any prescriptive requirements that constrain this initial inspection interval decision. Different companies have different internal practices. Personally, I think it's appropriate to leverage experience from similar services, even if they're at a different facility. There's no right or wrong answer. Consult with maintenance and/or process safety personnel within the company, and make a decision that's consistent with corporate risk tolerance.

do they send their relief valves onshore to be tested/overhauled or do they do it on the offshore rig?
