Pump design requirements in Drilling.
The pumps in the drilling industry are missing check valves on the outlet from the centrifugal & reciprocating pumps; Why are there no check valves in the drilling process? Are not Mud & check valves a good combination?
Additionally what are the filter...
Hi all. I have an existing piping & pump process system but will be updated to new design. There is a specification which states that “The HP mud pumps shall be located to allow gravity feed from mud tanks in case of failure of super charge pumps. Supercharge pumps shall have gravity feed...
Hi all, Application. Offshore platform.
Fire hazards in the utility areas are generally limited.. but why is it; Firewater diesel, emergency generator, and main transformer rooms .... all have there own self contained protection system , why aren't these also not connected to the main firewater...
Hi All,
I'm involved in the front end design of a platform, and I have a question to all you readers. The onset years, gas export is not a problem, after it goes through a series of recompressors it meets the export pressure of the grid. … But after the gas pressure decreases in the well we...
Hi All,
Can someone please explain the differences between Engineering Procurement Construction (EPC) and Engineering Procurement Construction Management (EPCm).
I’m under the impression, or told, that the main contractor hires in another company, say a project management company to help with...
What are the requirements to bump test a Meduim Voltage Motor directly coupled to a reciprocating compressor?
Does one need to have all the utilies operational, cooling water, air, lube oil, (flushed) ???
An answer in the simplest form would be appreciated, required for planning purposes...
Hi all,
When performing laser alignment must the coupling be removed?
I’ve witnessed a millwright/mechanical fitter performing an alignment check on a pump with the coupling installed, however the coupling bolts are loose.
Will this not prestress the alignment? REMOVE COULPING !!
Cheers in...
Non-Return Valves or Check Valves, which they are commonly known as, are inspected frequently during the shutdowns on this Oil Refinery. Therefore it’s been suggested to perform an RCM (Reliability Centred Maintenance) study. The Check valves in question are all above 2”, rated between 150 -...
What are the standard details for venting and draining in systems? I’ve been searching through ASME for a standard but to no prevail. Obviously certain rating have different specifications. This particular line I'm working on is a 1½” gas line with many branch connections. On the drain...
