Refrigerant supply to a cooling facility

A method for supplying refrigerants to a floating liquefied natural gas (LNG) facility, the method comprising:

• advancing a first refrigerant from a first storage device to a heat exchanger, the first refrigerant having a first temperature;
• advancing a second refrigerant from a second storage device to the heat exchanger, the second refrigerant having a second temperature different than the first temperature;
• adjusting the second temperature based on at least a transfer of heat between the first refrigerant and the second refrigerant in the heat exchanger;
• advancing the first refrigerant from the heat exchanger to a temperature control system to apply heat to the first refrigerant;
• advancing the second refrigerant from the heat exchanger to an expansion valve to reduce pressure of the second refrigerant;
• and
• transferring the first refrigerant from the temperature control system and the second refrigerant from the expansion valve to cooling cycles in the floating LNG facility,
• 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.
