There are several of high pressure cylinders that store gas in bladders and hydraulic fluid or water under pressure for hydraulic activated systems. Pressure based on 3, psi surface stack system that you should check on BOP remote panel and koomey unit is listed below: According to API RP 53, there must be 2 or 3 independent sources of power that will be available for each closing unit.
Typically, you will these following sources:. Please remember that the diagram is for learning purpose. It may or may not match with your rig configuration. However, the concept of it is the same.

Moreover, when accimulator function test BOP, you should see that the electrical and pneumatic pumps should kick in when pressure drops. Are the Koomey units still available on market? I cannot find any offial websitefo the Koomey company. I had one experienced with Koomy inspection and function test with third party team audit which required from our client This is required when new rig up as I was AD at land rig Thailand.
Physical inspection of all quipments in unit. Function of equipment such as electrical main control signal and alarm pilot lamp, oil level etc must be activate if working accumulwtor which you need to test in all situation that all alarm response. Check for nitrogen by connect gauge valve to show audit team all bottles are fill up 1, PSI. Rig Air accumulztor for us using psi accumuoator.
Bypass system working properly. Connection hose and supply to BOP stack Power aplly to system to check hose leaking and condition all connections must be secure Valve activate to control are correctly, Close and Open have to physical check at BOP stack during activate valve.
Hi, I want to know accumulator pressure in rig move Accumultaor transportation procedure of Koomey unit. Please I need Your Help. The Pressure then starts dropping by psi per 3 Minutes. NO internal or External Leakage Observed. It should accumulatot drop even though you have pre-charge only psi.
You many need to separate each section and do the pressure test to find the leak. What shall be the minimum wall thickness of Koomey bottle and Koomey lines? How often the wall thickness inspection to be carried out?
You need to ask the joomey for the information. Well I know 60 seconds or less to close annular and 45 seconds or less to close Ram Type preventers.
Where do I find the documentation for the procedure as far as…. Push the Function Button, start counting when Readback pressure starts to rise again stop counting. For the surface stack, it is a typical pressure at psi. You may get higher pressure in a deepwater system. Matt… You koomry a 4-way valve leaking…remove the avcumulator bung on each end of the accumulator and look through with flash-light… you will be able to see which valve is leaking.
You should contact manufactures which you may find on the internet. When we open keeping the 4-ways valve in open side 1. After taking the 4-ways valve from open side to neutral side, immediately pressure up to PSI. Open the plug on oil tank and check for returnu, koomwy can see from the pipe below the 4 way valve.
If is the valve you listen noise an the 4 way valve.
Or you disconnect the hose to annular and plug then operate the 4 way valve, if the pressure still drop is the valve leak otherwise is the piston seal on BOP.
