A system and a process are provided for transferring a cryogenic fluid such as liquefied natural gas between a floating transport vessel and a storage vessel. The fluid is transferred through at least one submerged/subsea/subsurface catenary flexible conduit, the conduits being configured to avoid damage from waves and abrasion or contact with the other conduits, the vessels, or other objects. A conduit transfer vessel is provided for storing the conduit in the water, delivering the conduit to each transport vessel, but standing off from the transport vessel during cryogenic fluid transfer, and then retrieving the conduit from the transport vessel, which greatly improves the safety of the cryogenic fluid transfer operations.

What is claimed is: 1. A process for transferring a cryogenic fluid from a first vessel to a second vessel, comprising: a. providing a cryogenic fluid transfer assembly having: i. at least one pipe spool supported on a floating conduit transfer vessel; and ii. at least one conduit having a first en
What is claimed is: 1. A process for transferring a cryogenic fluid from a first vessel to a second vessel, comprising: a. providing a cryogenic fluid transfer assembly having: i. at least one pipe spool supported on a floating conduit transfer vessel; and ii. at least one conduit having a first end which is swivably connected to the pipe spool, and a second end which is swivably connected to a second vessel; and b. transferring the at least one pipe spool to a first vessel, and connecting the pipe spool to a connection means comprising a quick release connection on the first vessel, wherein the conduit is maintained in a catenary configuration between the second vessel and the first vessel with only the first and second ends of the conduit exposed above water. 2. The process of claim 1, further comprising passing a cryogenic fluid through the cryogenic fluid transfer assembly between the first vessel and the second vessel. 3. The process of claim 1, wherein the conduit is a flexible catenary hose. 4. A process for transferring a cryogenic fluid between a first vessel and a second vessel, comprising: a. providing a flexible conduit, having a catenary shape, the conduit being supported at a first end by a first vessel and at a second end by a second vessel, wherein the conduit is substantially submerged in the body of water; b. transferring the second end of the flexible conduit from the second vessel to a third vessel; c. connecting the second end of the flexible conduit to the third vessel, wherein the flexible conduit is maintained in a catenary configuration between the first vessel and the third vessel with only the first and second ends of the flexible conduit exposed above water; and d. passing a cryogenic fluid through the flexible conduit between the first vessel and the third vessel. 5. The process of claim 4, wherein the first vessel is a storage vessel, the second vessel is a conduit transfer vessel, and the third vessel is a transport vessel. 6. The process of claim 4, wherein the flexible conduit is selectively weighted such that the conduit is maintained in a catenary configuration during transfer of the cryogenic fluid through the conduit. 7. A process for transferring a cryogenic fluid between a first vessel and a second vessel, comprising: a. providing a flexible conduit system which includes a flexible conduit, having a catenary configuration, and further having a first end and a second end, and at least one connection means connected to the second end, wherein the flexible conduit is substantially submerged in a body of water; b. supporting the first end of the flexible conduit on a first vessel, c. supporting the second end of the flexible conduit on a second vessel; d. transferring the second end of the flexible conduit from the second vessel to a third vessel; e. connecting the second end of the flexible conduit to the third vessel via the connection means, wherein the flexible conduit is maintained in a catenary configuration between the first vessel and the third vessel with only the first and second ends of the flexible conduit exposed above water; and f. passing a cryogenic fluid through the flexible conduit between the first vessel and the third vessel. 8. The process of claim 4, wherein the cryogenic fluid is liquefied natural gas. 9. The process of claim 7, wherein the cryogenic fluid is liquefied natural gas. 10. The process of claim 7, wherein the cryogenic fluid is liquefied heavy gas. 11. The process of claim 7, wherein the cryogenic fluid is liquefied petroleum gas.
