HYDRAULIC ANALYSIS AND DETERMINATION OF DEGREE OF FIRE OF THE C.P. AKAL-B.

CONTEXT OF THE PROJECT

The AKAL-B Complex is made up of different platforms that have a seawater based fire protection system that consists of a general network for the fire protection service. The hydraulic analysis of the Fire Protection System is done by technical personnel certified by NFPA in order to evaluate and validate the effectiveness of the system, including the performance tests of the firefighting pumps and mitigation equipment associated with the firefighting water network and the sprinkler systems (flow, pressure and velocity) ensuring legal compliance.

OBJECTIVE

TECHNICAL CONTEXT

  1. The location of the pumps in the isometric maps and DTIs was identified.
  2. The performance curves of the firefighting pumps belonging to C.P. AKAL-B were reviewed.
  3. The firefighting systems and equipment that are in the different platforms of the AKAL-B complex were identified.
  4. The nodes and capture of information in specialized commercial software were defined for the modeling of the firefighting network of the C.P. Akal-B for DEMAND:
    • Water use that the sprinkler system requires (Qrequerida)
    • Pressure that the sprinkler system needs (Prequerida)
    • Flow velocity up to 15 ft/seg.
  5. The nodes and capture of information in specialized commercial software were defined for the modeling of the firefighting network of the C.P. Akal-B for SUPPLY:
    • Losses from friction.
    • Flow velocities.
    • Use that can supply the pipe and pump system.
    • Residual pressure in the exit points of water to the sprinkler systems and other accessories (Monitors and Hydrants).
  6. Analysis of results and recommendations.

RESULTS OBTAINED

As a result of the data obtained by the hydraulic simulations for demand and supply, a series of recommendations were obtained oriented toward normative compliance of the firefighting network of the C.P. Akal-B, and the analysis was obtained of degree of fire of the installation in accordance with the NOM-002-STPS-2010. The above studies were validated by a NFPA Certified Fire Protection Specialist(CFPS).
