FPEC is only one consultant in Japan specialised to plant disaster prevention

Plant Disaster Prevention Consulting

  • Safety review for plant design / operation / management
  • Support of application to fire brigade (especially for application of both Japanese fire service law and other safety codes / standards)
  • Explosion proofing measures
  • Response and countermeasures after the accident
  • Quantitative Risk Assessment (QRA) of accidental discharge, evaporation, dispersion, fire and explosion of hazardous material, with consideration of risks frequency and effects
  • Plant disaster assessment and safety study by using various PC programs owned by FPEC and our partners
  • Draft of global safety standards

Plant Disaster Preventing Simulation

  • Accidental discharge and spreading, evaporation, gas / odor dispersion of hazardous material
  • Spill fire, tank fire and boilover
  • Explosion (VCE, BLEVE), fireball, flashfire
  • Fire protection planning / equipment mapping by using water / foam trajectory simulation program

Plant Disaster Prevention System Engineering

  • Fire fighting system
  • Fire pump, fire main piping
  • Fire / gas detection system
  • Consideration of back-up system of electrical / air / N2

2018.8.1 Disaster Simulation in Series


We, FPEC can carry out disaster simulation in series on the sequence from the initial events, such as leakage and evaporation to gas diffusion, fire and explosion, and can evaluate the Severity of each disaster.
The following is the sample list of the evaluation item per each step of disaster scenario.

Leak from
Sphere Tank
Crude Oil Tank
Full Surface Fire
Leak from Pressure Vessel
storing Toxic Gas
Contents Leakage is occurred.
(calculate the
volume of

leakage and
evaporation gas)
Full surface fire
is occurred.

(calculate heat
flux level

from fire)
Leakage is occurred.
(calculate the volume
of leakage and evaporation gas)
Gas Diffusion
(calculate the area that
concentration of gas will be larger than
50% of LEL -

as the area in danger of
flash fire)
Fail to extinguish the fire
and boil-over is occurred.
(calculate the time of
and remaining volume of oil at
the boil-over)
Gas Diffusion
(calculate the concentration of
gas as ppm, LEL,
or odor level

by each time step)
Ignited and flash fire
is occurred.

(calculate the area
enveloped by
the flash fire)
Calculate the heat
flux level

from boil-over
and area of
splashing fired oil
As the result of back fire,
dike fire
is occurred.
(calculate heat flux level
from fire)
Fail to extinguish the fire
BLEVE is occurred.
(calculate the range of
pressure wave
and area
in danger of spreading debris)
Fireball is occurred.
(calculate the heat flux from
the fireball)

Also for VCE (Vapour Cloud Explosion), we can evaluate the Severity of pressure wave based on the scenario.

We also can conduct QRA to extract disaster scenario of high risks, and according to the scenario, we will carry out the evaluation of its Severity.
