    deepak one mast riser is connected to multiple tanks connecting cargo tank venting/ inert main.
    PV v/v is provided in all the tanks.

    The mast riser is normally used during loading for tank vapour pressure control.
    PV valve operates overtime when their is change in the tank pressure.

    Mast exit location, being at least 6 metres above the deck.
    PV valve located at least 2 metres above the deck.
