In order to provide improved efficiency, e.g. in terms of how to operate and maintain a liquid natural gas (LNG) transfer system, while also improving the environmental friendliness of the transfer operation, there is disclosed a method and system of transferring liquid natural gas from a first container 104 to a second container 106 via a pump station 108. The first container 104 is positioned close to the pump station 108 by a truck 110, and the second container 106 is positioned close to the pump station 108 by a ship 112. Repeated transfer of LNG is provided using first and second dry couplings 304, 308 and, after transfer is complete, disconnecting the second dry coupling 308 from the second container and providing a flow of liquid natural gas back into the first container utilising an overpressure in the insulated pipes or hoses 202, 208 and in pipes of the pump station relatively to the pressure in the first container and by replacing the first container 104 with a filled first container when the first container is empty. |
