What are the Major causes of static electricity build up during liquid cargo operations ?

LINE DISPLACEMENT 

Uses of compressed air or inert gas are prohibited in order to clear the pipelines since it may produce flammable vapour unless appropriate precautions are taken. This again may cause water at the bottom of the tank as turbulent. Normal practise is to purge by nitrogen gas. 

DISCHARGING 

The initial loading rate is kept minimum until the shore readiness is received. This is to avoid discharging distillate oils, which may produce flammable vapour.
