ABSTRACT:
In pumping LNG (liquefied natural gas) from one receiver to another, e.g. from a vessel's tank to a shore installation, it is conventional to use a submerged pump, a riser pipe connecting the pump to a stop valve and flexible joint connecting the stop valve to a header. If a pocket of gaseous LNG is present in the riser pipe, when the pump commences its operation, the advancing column of liquid in the riser pipe slams against the stop valve and may damage it. The invention provides the improvement of a removable or bypassable flow restrictor incorporated between the pump and the riser pipe, permitting to ensure that the riser pipe is completely liquid-filled, before the pump commences to operate.
