Abstract
A coastal installation for loading or unloading liquefied natural gas comprises a fixed tower installed on a seabed close to a coast and carrying at the top a rotating mooring arm and a rotating loading arm. Cryogenic pipes connect the coast to the tower, the pipes passing from the coast to below the tower inside a tunnel and then up the tower in at least one vertical casing which penetrates into the tunnel at a point vertically in line with the tower, the upper ends of the pipes being connected to pipes carried by the loading arm by a rotating joint. The cryogenic pipes are thus sheltered against the sea and access to the installation is possible for ships in practically any weather.
