Notes:

Seawise Giant, later Happy Giant, Jahre Viking, Knock Nevis, Oppama, and finally Mont, was a ULCC supertanker and the longest ship ever built. It possessed the greatest deadweight tonnage ever recorded. Fully loaded, its displacement was 657,019 tonnes (646,642 long tons; 724,239 short tons), the heaviest ship of any kind, and with a laden draft of 24.6 m (81 ft), it was incapable of navigating the English Channel, the Suez Canal or the Panama Canal. Overall, it was generally considered the largest ship ever built. It was sunk during the Iran–Iraq War, but was later salvaged and restored to service. It was last used as a floating storage and offloading unit (FSO) moored off the coast of Qatar in the Persian Gulf at the Al Shaheen Oil Field.

The vessel was sold to Indian ship breakers, and renamed Mont for its final journey in December 2009. After clearing Indian customs, it was sailed to, and intentionally beached at, Alang, Gujarat, India, to be broken up for scrap.

Seawise Giant was ordered in 1974 and delivered in 1979 by Sumitomo Heavy Industries, Ltd. at its Oppama shipyard in Yokosuka, Kanagawa, Japan as a 418,611 ton ULCC. The vessel remained unnamed for a long time, and was identified by its hull number, 1016. During sea trials, 1016 exhibited massive vibration problems while going astern. The Greek owner refused to take delivery and the vessel was subject to a lengthy arbitration proceeding. Following settlement the vessel was sold and christened Oppama by S.H.I.
