6.8 Vapour emission

 On ships to which these Specifications apply there shall be means to avoid vapour emission during the filling of departure ballast wherever local conditions require it. The method of preventing the emission of hydrocarbon vapour into the atmosphere shall be:

  • (a) By the use of permanent ballast tanks wherever these are sufficient to provide the minimum departure draught; or

  • (b) By containment of vapour in empty cargo tanks by simultaneous ballasting and cargo discharge.

Alternative methods to the satisfaction of the Administrations may be accepted provided an equivalent degree of environmental protection is provided.
