- the movable arm 74 can be adapted to all gauges of LNG carriers .
- a connection pipe (not shown) extends inside the tower 78.
- the loading and unloading station 75 enables the loading and unloading of the LNG tank 70 from or to the shore facility 77.
- the underwater line 76 allows the transfer of the liquefied gas between the loading or unloading station 75 and the onshore installation 77 over a large distance, for example 5 km, which makes it possible to keep the tanker vessel 70 at great distance from the coast during the loading and unloading operations.
