1. A method for commissioning an FLNG vessel, comprising:
positioning the FLNG vessel being commissioned at an offshore location within forty miles of a shipyard;
positioning a regasification vessel comprising an LNG cargo adjacent the FLNG vessel being commissioned;
regasifying the LNG cargo onboard the regasification vessel to produce high pressure natural gas;
transferring the high pressure natural gas from the regasification vessel to a liquefaction module onboard the FLNG vessel being commissioned;
liquefying at least a portion of the high pressure natural gas using the liquefaction module onboard the FLNG vessel being commissioned to produce reliquefied natural gas;
storing the reliquefied natural gas in a storage tank onboard the FLNG vessel being commissioned; and
returning the reliquefied natural gas from the storage tank onboard the FLNG vessel being commissioned to a cargo tank onboard the regasification vessel.
