Abstract
A system for transfer of liquefied natural gas (LNG) between two vessels (1, 2). The system comprises a coupling head (7) mounted at one end of a flexible pipe means (4) and arranged for attachment on a platform (19) at one end of one vessel (1) when it is not in use, and a connection unit (8) mounted at one end of the other vessel (2) and comprising a pull-in funnel (50) shaped for guided pull-in of the coupling head (7) to a locking position in which the pipe means (4) can be connected to transfer pipes (56) on the other vessel (2) via a valve means (31) arranged in the coupling head. The coupling head (7) is provided with a guide means (40) and is connected to at least one pull-in wire (42) for guided pull-in of the coupling head (7) into the connection unit (8) by a winch means (66) an the other vessel (2).
