Abstract
A system and method to transfer a cryogenic liquid from a station tank system to a recipient tank is provided. At least a part of said cryogenic liquid is stored at a first pressure higher than the pressure in said recipient tank and is cooled to a temperature below the equilibrium temperature for said first pressure. The cooled part of said cryogenic liquid is transferred to said recipient tank.

Method of transferring cryogenic liquid to a recipient tank from a station tank system which includes a first tank and a second tank, said method comprising:
- storing at least a part of said cryogenic liquid within said station tank system at a first pressure which is higher than a pressure in said recipient tank,
- transferring a part of said cryogenic liquid from said first tank to said second tank with cooling thereof to a temperature below an equilibrium temperature for said first pressure to form a cooled part of said cryogenic liquid, and
- transferring said cooled part of said cryogenic liquid from the second tank to said recipient tank,
- wherein said second tank is pressurized by feeding gas from the first tank to the second tank to subcool said cryogenic liquid in said second tank and to create a differential pressure necessary for said transferring of said cooled part of said cryogenic liquid to said recipient tank.
