OBJECTIVE

The purpose of Fire Proofing Requirement Qualitative Assessment is to establish the criteria for the proper selection of (a) the proper fireproofing material; (b) the structures and equipment that should receive fireproofing protection; and (c) the extent of the fireproofing application.

The primary objective is to provide sufficient protection to allow for the following actions:

• Prevent the collapse of structures and equipment and thereby, prevent the release of flammable fluids from failed equipment that could result in the escalation of a fire event.
• Protect occupied areas from structural collapse; as well as to protect escape routes that allow for an orderly evacuation of personnel from the affected area.
• Protect critical shutdown and control circuits, maintaining integrity of emergency equipment and thus, allowing for an orderly shutdown.
• Provide protection of assets and limit the exposure to consequential damage, whether from equipment replacement or business interruption.

SCOPE

The qualitative assessment of fireproofing requirements focuses on identifying where, what type, and to what extent fireproofing is needed based on fire exposure scenarios, equipment criticality, and safety objectives, without performing detailed quantitative fire calculations.

2. As per Client Guidelines
3. National & International reference books.

Proposed Methodology

1. Introduction
2. The fire proofing assessment methodology presented in this document is based on a qualitative, risk-based fire scenario envelope methodology. The approach is aligned with established oil and gas industry practices and is intended to identify the need, extent, and rating of passive fire protection without performing detailed quantitative fire or thermal radiation modeling.
   1. Methodology
3. Step 1: Identification of Fire Potential Equipment
4. Process equipment is screened to identify fire potential based on:
5. Inventory of flammable or combustible fluids
6. Operating pressure and temperature
7. Flow rate and leak potential
8. Heat of combustion
9. Presence of lubricating oil systems
10. Based on these parameters, equipment is categorized as high or low fire potential

1. Step 2: Definition of Fire-Exposed Envelope
2. For each fire potential equipment item, a fire scenario envelope is defined. The base envelope dimensions as per API section 5.2.

1. Step 3: Determination of Fireproofing Extent and Rating
2. All structural steel, equipment supports, pipe racks, platforms, vessel skirts, and critical systems located within the fire-exposed envelope are evaluated for fireproofing. Fireproofing ratings as per API section 5.2.
