Blowdown Initiated by Flare KOD LSHH
Blowdown Initiated by Flare KOD LSHH
(OP)
Hi,
Recently i am assigned to be seconded to another oil and gas company. This question may be just resulted in Different company standard, but i am really curious about the philosophy behind it.
So far, what i encountered in oil platform, LSHH at flare KOD (Knock Out Drum) will initiate platform shutdown, but not automatic blowdown. I am in agreement with this as you want to stop all flow feeding into the vessel. This new platform i am assigned to work with is different. LSHH at KOD will not only shutdown the platform, but also initiate blowdown. Does anyone know what may be the philosophy behind it? Wouldn't it be more dangerous if we have a high level in KOD, then we feed the vessel with gas inventory from blowdown?
Thanks!

Did you mean the automatic depressurizing will be triggered by LSHH at KOD simultaneous with platform shutdown? If so, please specify if the depressurizing will be done in sequential manner; i.e. the vessels will be depressurized one after another...

E.g. NORSOK (S-001) has the opposite philosophy (isolation but NO blow down)
