Claim 10:
11. A method to supply refrigerants to a floating liquefied natural gas (LNG) facility, the method comprising:
heating, via a temperature control system, a first refrigerant received from a heat exchanger;
reducing, via an expansion valve, pressure of a second refrigerant received from the heat exchanger; and
transferring the first refrigerant and the second refrigerant to cooling cycles in the floating LNG facility during a first-fill procedure,
wherein,
the second refrigerant is introduced to the floating LNG facility, during a first-fill procedure at a different pressure than subsequent introductions of the second refrigerant to the floating LNG facility,
the first-fill procedure of the second refrigerant is performed prior to operation of the floating LNG facility, and
the subsequent introductions of the second refrigerant occur during the operation of the floating LNG facility.
