It has a deadweight of 564,763 tonnes and a summer displacement of 647,955 t when laden with nearly 650,000 m³ (4.1 million barrels) of petroleum. The ship has a draft of 24.6 m (81 feet) when fully loaded, which makes it impossible for the ship to navigate even the English Channel, let alone man-made canals at Suez and Panama.
