Fireproofing of firewater system pipe support???

[Techsafety]

Norsok S-001 stated
"19.4.4 Equipment intended to function during a dimensioning fire shall have adequate fire protection.
Requirements for fire protection and the use of PFP shall be assessed in relation to safety criticality and the fire risk in the area. This applies to protection of equipment such as:
• suspension for important pipes (as fire fighting, flare/vent lines) and important ducting"

Am able to find a number of reference regards PFP of hydrocarbon piping, but not so on firewater system. Does anyone have experience with fireproofing firewater system exposed to jet fire scenario?

Would greatly appreciated any feedback.

it is useless provide fireproofing for jet fire scenarios, you should check pool fire scenarios.
