The Jᴀᴘᴀɴese company Sumitomo Heavy Industries produced the ULCC supertanker Jahre Viking, also known as Seawise Giant, Happy Giant, Knock Nevis, Oppama, and ultimately Mont. It was the lengthiest ship ever built. It carried the heaviest reported weight tonnage. Its displacement when fully loaded was 657,019 tonnes.

With a loaded draft of 24.6 m (81 ft) and an incredible length of 1504 ft (458 m), the heaviest ship ever was unable to pass through the English Channel, Suez Canal, or Pᴀɴᴀᴍᴀ Canal. It is thought to be the biggest ship ever built. It used Ljungström turbine technology to power its engines.

The largest ship constructed in the 20th century was the Jahre Viking. The Exxon Valdez ᴀᴄᴄɪᴅᴇɴᴛ, which gave rise to the double-hulled tanker era, occurred before the Cossus was constructed, though.

It is unlikely that the Jahre Viking will get any larger, and new tankers are more likely to be halted by actual floating towns with residences, businesses, and other amenities. Such vessel initiatives are frequently already underway.
