Criteria for Deluge on an Onshore Facility

Criteria for Deluge on an Onshore Facility

Criteria for Deluge on an Onshore Facility

(OP)
Hey Everyone,

Does anyone know if there is certain criterion that needs to be followed for the application of deluge on vessels in an onshore facility? The current design we have for an LNG facility includes deluge for high risk vessels (definition of high risk a bit vague, mostly those which can not be reached with water monitors). The deluge is in addition to the blowdown system, paving, passive fire proofing and fire water hydrants and monitors, although I have seen that in some cases on onshore facilities with such measures as those stated above, the deluge is avoided due to minimum chances of escalation with the decks mostly grated and less chance of a pool fire accumulation. We have further adopted a 9m approach, i.e. that vessels are provided coverage up to 9m from the grade level as it seems to be industrial practice that a reach of a pool fire can only be up to 9m, probably from Shell? Does any one have any comments to what I have stated? Are you aware of any such 9m criteria and where it comes from? Has anyone worked on an onshore facility which has used deluge for equipment within the train apart from the LPG storage vessels?
 

RE: Criteria for Deluge on an Onshore Facility

Can't directly comment but some industry standards you might want to look at are:

API 2218 Fireproofing Practices in petroleum and Petrochemical Processing Plants

API 2510 Design and Construction of LPG Installations

API 2510A Fire Protection Considerations for the Design and Operation of LPG Storage Facilities

Thanks RNeill,

I will look into those, however I was more after precatices adopted in the LNG facilities but these might be useful.

Thanks and regards.
