The ship that was cut in half and stretched to become the largest vessel in history ... 

In 1981, Seawise Giant underwent a dramatic jumboisation at the Sumitomo Heavy Industries shipyard in Japan. Originally measuring about XXX meters, the ship was cut into two and extended by inserting a massive midsection. This modification increased its overall length to XXXXXX meters.

Alongside the length extension, its deadweight tonnage rose from approximately XXXXXXX DWT to XXXXXXX DWT, making it the largest ship in the world by carrying capacity. After this transformation, Seawise Giant was too large for the Suez, Panama, or English Channel and earned a place in maritime history as the most massive moving man-made object ever constructed.
