Abstract
An installation for storing and transporting a cryogenic fluid on a ship includes: a sealed and thermally insulating tank, having a ceiling wall including, from the outside to the inside, a primary thermally insulating barrier and a primary sealing membrane intended to be in contact with the cryogenic fluid; and a sealed line penetrating through the ceiling wall of the tank, the line including a bottom portion of which a first end is situated inside the ceiling wall of the tank and a second end is situated outside the ceiling wall of the tank in a thicknesswise direction of the ceiling wall, and a top portion fixed to the second end of the bottom portion. The bottom portion includes an alloy with low thermal expansion coefficient. The primary sealing membrane is tightly fixed to the bottom portion of the line around the line.
