Liquefied natural gas recondensation system and related methodology

A method of increasing output of liquefied natural gas from a storage tank, the method comprising the steps of:

• extracting liquefied natural gas from the storage tank;
• increasing the pressure of the extracted liquefied natural gas to a first liquefied natural gas pressure;
• extracting boil off gas from the storage tank;
• liquefying at least a portion of the extracted boil off gas by combining the extracted boil off gas with a portion of the extracted liquefied natural gas at the first liquefied natural gas pressure to produce a combined fluid;
• and
• increasing the pressure of the combined fluid.

A gas recondensing system comprising:

• a first pump disposable in communication with a storage tank configured for storing liquefied natural gas and boil off gas, the first pump being configured to receive the liquefied natural gas from the storage tank at a first inlet pressure and output liquefied natural gas at a first output pressure greater than the first inlet pressure;
• an ejector disposable in communication with the storage tank to receive boil off gas therefrom at a boil off gas inlet pressure, the ejector further being disposable in communication with the first pump to receive liquefied natural gas at the first output pressure, the ejector being configured to combine the received boil off gas and liquefied natural gas and utilize the first output pressure as a motive force to output the combined liquefied natural gas and boil off gas at an ejector output pressure greater than the boil off gas inlet pressure;
• and
• a second pump disposable in communication with the ejector and configured to receive fluid output from the ejector and elevate the pressure thereof to a pressure greater than the first output pressure.
