Integrally-transportable purge container and method of using the integrally-transportable purge container

An integrally-transportable purge container for exposing a submersible pump to purge gas, the submersible pump being used to deliver liquefied gas, the integrally-transportable purge container comprising:

• a container body having an interior space for accommodating the submergible pump therein;
• an upper lid configured to cover an upper opening of the container body;
• a lower lid configured to cover a lower opening of the container body;
• a purge-gas inlet port and a purge-gas outlet port communicating with the interior space of the container body;
• and
• a sealing member configured to seal a gap between the container body and the lower lid when the lower lid covers the lower opening of the container body,
• wherein the lower opening of the container body has a size that allows the submergible pump to pass through the lower opening when the lower lid is removed, and
• the integrally-transportable purge container is transportable together with the submergible pump disposed in the container body to an upper portion of a pump column and away from the upper portion of the pump column.

• and
• a pump guide configured to suppress lateral shaking of the submergible pump when the submergible pump is in the container body,
• wherein a predetermined clearance is maintained between the pump guide and the submergible pump, and
• the integrally-transportable purge container is transportable together with the submergible pump disposed in the container body to an upper portion of a pump column and away from the upper portion of the pump column.
