When applying GRS technology during the discharge operation of a certain liquefied gas and if afterwards a purging operation has to be performed, GRS makes it possible to recover the vapour atmosphere completely, product otherwise remaining in the cargo tanks after completion discharge.

Besides a total recovery of the vapour atmosphere representing valuable product, the vessel will leave the discharge port with the cargo tanks already under nitrogen atmosphere. Time for purging is saved and in some cases the used of the ship’s inert gas plant is avoided. Moreover, the environment has been protected from the emission of VOC’s or carbon dioxide.

In general berth occupation will be reduced, gas carriers will be employed at a more efficient and cost efficient way.
