METHOD FOR TRANSFERRING LNG FROM A SHIP TO A FACILITY

摘要

A system for transferring liquid natural gas from a ship to a facility, the transfer system comprising: a hoisting device which is designed to be secured on the deck of the ship; a mobile chassis, which is supported by the hoisting device; a first on-board pipe, for transferring liquid natural gas from the ship to the facility, said first on-board pipe being supported by the mobile chassis; and a second on-board pipe for the transport of inert gas, said second on-board pipe being supported by the mobile chassis comprising a first connection element which is associated with the second duct, and being connected to the first on-board pipe between the valve and the second connection element of the first on-board pipe.
