The system comprises a shaft extended upwards to above the sea level, at least one dolly for the transfer pipeline at the free end, an internal hose, and a loading arm for connection with a ship manifold. The loading arm further comprises an external hose as well as an elbow spool, a valve, an end flange at its mobile end for connecting with a ship manifold. A crane is used to lift the mobile end of loading arms between a loading position and storing position. Internal and external hoses are freely hanging catenary for accommodating end displacements of a transfer pipeline and ship motions, respectively. ## Claims ### Claim 1 A system for transferring fluids between a ship with a ship manifold and onshore storage tanks at either a loading terminal or a receiving (i.e., unloading) terminal comprises a transfer pipeline with a free end on the ship side and a loading system that extends from said free end to said ship manifold, said loading system comprising: a) a reinforced concrete shaft to host said free end of said transfer pipeline; b) at least one dolly for said free end so that said transfer line can expand/contract axially at said free end inside said shaft; c) a hose hanger supported around the top of said shaft; d) an internal hose fluidly connected with said free end, and freely hung inside said shaft between said free end and said hose hanger; e) an external hose with one end hung at said hose hanger and a mobile end; f) an elbow spool, a valve and an end flange fluidly connected with said external hose at said mobile end; g) a storing seat above the sea level and away from said ship; h) a crane to lift said mobile end between a storing position on said storing seat and a loading position that is fluidly connected with said ship manifold. ### Claim 2 (depends on 1) The loading system of claim 1, wherein said hose hanger is a n-shaped coupler. ### Claim 3 (depends on 1) The loading system of claim 1, wherein said hose hanger is a convex saddle. ### Claim 4 (depends on 3) The loading system of claim 3 further comprising a rigid n-shaped coupler and a second internal hose that reaches to said transfer pipeline at a distance below. ### Claim 5 (depends on 3) The loading system of claim 3, wherein said convex saddle comprising a group of roller bars. ### Claim 6 (depends on 5) The loading system of claim 5, wherein said convex saddle further comprises a belt that is wrapped around said roller bars and driven by a motor. ### Claim 7 (depends on 1) The loading system of claim 1, wherein said dolly comprises at least two wheels rolling along a metal track. ### Claim 8 (depends on 1) The loading system of claim 1, wherein said mobile end further comprise a powered emergency release coupler (PERC), and a quick connecting and disconnecting device. ### Claim 9 (depends on 1) The loading system of claim 1 further comprising a transfer seat. ### Claim 10 (depends on 9) The loading system of claim 9, wherein said transfer seat further comprises a main leg and an assistant leg. ### Claim 11 (depends on 10) The loading system of claim 10, wherein said legs comprise a plate at the bottom, a column in the middle, a concave top, and two alignment guides extending up. ### Claim 12 (depends on 11) The loading system of claim 11, wherein said concave top is formed from at least one roller. ### Claim 13 (depends on 11) The loading system of claim 11, wherein said concave top is a concave saddle. ### Claim 14 (depends on 11) The loading system of claim 11, wherein said concave top is a combination of a concave saddle and roller. ### Claim 15 (depends on 11) The loading system of claim 11, wherein said legs further comprise a male bar at the bottom. ### Claim 16 (depends on 1) The loading system of claim 1 further comprises a surge drum inside said shaft with hose connection between said surge drum and said transfer pipeline. ### Claim 17 (depends on 1) The loading system of claim 1 further comprises a second transfer pipeline and a hose freely hung between the two transfer pipelines for fluid connection. ### Claim 18 A method for transfer cryogenic fluids at a loading or unloading terminal between a ship with a ship manifold and a free end of a transfer pipeline that is extended from the free end near the ship to onshore storage tanks, said method comprising: a) building a shaft extended upwards to above the sea level to host said free end; b) using at least one dolly for said transfer pipeline at said free end; c) fluidly connecting said free end with an internal hose and an external hose and a hose hanger in the middle of the two hoses; d) fluidly connecting a mobile end of said external hose with an elbow spool, a valve and an end flange; e) lifting the mobile end of said external hose over with a crane and making fluid connection with said ship manifold. ### Claim 19 (depends on 18) The method in claim 18 further comprises lifting mobile end of said external hose to a storing seat stood away from said ship when a loading operation is over. ### Claim 20 (depends on 18) The method in claim 18 further comprises hanging a rigid n-shaped coupler and another flexible hose to fluidly connect said free end that is located at a distance below.
