Calculating safety distances by o Programs like Phast DNV, Effects, Safeti to give an indication of the effects on

thermic and concentration (Quick & dirty methods) o More specific with Computational Fluid Dynamics o Literature study o Depends on:

A. Source type (liquid, gas, vapour, composition) B. Atmospheric conditions (wind, temperature, humidity, turbulence) C. Ground effects (surface, heat flux, obstacle)

Evaporating rate in water 15 m3/min/m2

Evaporating rate on land (depends on type of soil) 3 m3/min/m2 In steady state 0,3 m3/min/m2

Possible impact of an accident with LNG? o Type release -> Atm. Pressure (instantaneous vs continuous) pool fire, vapour

cloud explosion, flash fire, cryogenic effects o -> 4 Bar(g) (instantaneous vs continuous) BLEVE, fire ball, flash fire, jet fool

and the rest as mentioned above Prohibited areas for the storage and bunkering of LNG, near schools and

hospitals and other (partly) dependent people

LNG aspects in the Netherlands 19

Safety standards for staff/crews (distances) Distances o Loss of control in gas (LEL Distance: 250*D) o Loss of control in liquid (LEL Distance: 500*D) o Flare Distance in liquid: 250*D o Flare Distance in gas: 500*D o Evacuation and preventing ignition sources 2*Flare Distance or 2*LEL Distance
