They were built in the Bassin C dock of the Chantiers de l'Atlantique shipyards at Saint Nazaire, France.Measured by gross tonnage, these were, at the time, the largest ships of any type Despite its great length, Seawise Giant was not the largest ship by gross tonnage, ranking fifth at 260,941 GT, behind the four 274,838 to 275,276 GT Batillus-class supertankers.
