The huge ship was over 1,500 feet long. It was too large to pass through the English Channel or the  Suez and Panama canals. The length of the ship from tip to tip was 458.45 meters.

History of Knock Nevis  


In 1974, the Greek owner commissioned Sumitomo Heavy Industries to build a large tanker. Construction took a total of five years. The order was delivered in 1979 from the same industry. Unfortunately, the Greek customer went bankrupt at the time of delivery and refused to accept the ship. The ship’s manufacturer called it Oppama. The ship was then put up for sale and eventually purchased by a Hong Kong-based company called  Hong Kong Orient Overseas Container Line (OOCL). The company increased the ship’s length by many more meters. This process took almost two years to complete.


At the end of her life, this ship was launched in 1981 under the name “Sea Wise Giant”. As already mentioned, the Sea wise Giant had a carrying capacity of more than 564,000 tons and a length of 458.45 meters. She also had a width of 69 meters and a draft of almost 25 meters. Knock Nevis had over 31,451 square meters of deck space and a total of 46 tanks. It was part of the war between Iran and Iraq. In 1986, it was hit by an Exocet missile in shallow waters off Iran’s Kharg Island.

It sank into these waters. The ship was transporting Iranian oil when it was attacked by an Iraqi parachute bomb. The ship caught fire, caught fire, and eventually sank. But the story of the largest ship in human history doesn’t end there. In 1989, nearly a year after her sinking, the ship was recovered from the seabed by a Norwegian conglomerate called Norman International, which purchased the wreck. 

The wreck was transported to Singapore for extensive repairs. The ship was so badly damaged that it took a long time to repair it. The ship was then repaired in Singapore. She was renamed Happy Sea Wise Giant in Singapore. In 1991, the ship was sold again to a Norwegian shipowner named Jørgen Hers Jarls. He renamed her ship Years Viking. In 2004, her ship was sold again. This time, I purchased First Olsen Tankers. They renamed the ship Knock Nevis, which became the ship’s most common name. This is the same name it is called today. Subsequently, the ship was used many times as a mobile offshore platform or floating storage and unloading unit.


At the end of January 2010, the Amber Development Corporation bought back her ship and changed her ship name to her M/V Mont. They just brought this ship for the last voyage. The trip ended in Alang, India. Eventually, it was whittled down to its final destination. This was the end of the journey of the life of the largest ship ever built by mankind.
