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

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

Disaster Management

Emergency response - fire

Emergency response - rescue

Disruption business as usual

Mutual Aid – LNG (e.g. TUI)

Steel structures failing

Major pool or gas release

Roll over truck

Transfer content damage teuck

Flare

Leakage in gas fase

Maintenance pipework valves

Prevent BOG

Disturbance/error in LNG instruments Operator LNG system

LNG intervention
