A Brief History: From Construction to Renaming


The “Knock Nevis,” formerly known as the “Seawise Giant,” was a massive supertanker and one of the largest ships ever built. It was originally constructed in 1979 by Sumitomo Heavy Industries in Japan. The ship’s name changed over the years due to various ownership changes and mergers in the shipping industry.

At its peak, the Knock Nevis had a length of about 458 meters (1,504 feet), a width of 68 meters (223 feet), and a maximum loaded draft of around 24 meters (79 feet). It had a carrying capacity of over 564,000 tons of deadweight (DWT). The vessel was primarily used for transporting crude oil.

The Knock Nevis gained attention for its sheer size and scale, as well as its role in the shipping industry. It was a part of the Ultra Large Crude Carrier (ULCC) category, designed to transport vast amounts of oil across long distances. However, changes in the oil industry, as well as concerns about the environmental impact and the challenges of maneuvering such a massive ship, led to its eventual retirement.

In 2010, the ship changed hands to a shipbreaking company, which then proceeded to dismantle and scrap it in Alang, India. The process of scrapping such a large vessel took several years to complete.

The Knock Nevis remains a notable example of the engineering feats achieved in the maritime industry and the evolution of shipping technologies.

Technical Specifications: Exploring the Vast Dimensions and Capacities

Prepare to be astonished by the numbers – the Knock Nevis reached dimensions previously unheard of in the maritime world. Stretching an astonishing length of over 1,500 feet, it could easily eclipse well-known landmarks like the Eiffel Tower. This supertanker boasted a cargo capacity that could make your jaw drop, setting records that remain unchallenged to this day. The raw power of its engines further underlined its dominance on the high seas, making it a true leviathan of transportation.

An Engineering Marvel: Overcoming Challenges in Design and Operation

Behind every grand success, challenges are abound. The supertanker’s engineering team faced a myriad of obstacles during its design and operation. Due to its size, it needed unique ballast systems to maintain equilibrium in the stormy ocean. The Knock Nevis skillfully navigated the vessel through small passages and crowded ports, performing like a needle in a storm.

The Life and Legacy of the Knock Nevis: A Gamechanger in Global Shipping

The Knock Nevis didn’t merely sail the seas; it reshaped the global trade industry. With its capacity to transport vast quantities of oil in a single voyage, it revolutionized the oil transportation sector. The world watched as it traversed waters, reducing the number of journeys required and cutting costs for oil companies. This floating colossus became a symbol of human achievement, representing the relentless pursuit of innovation in the face of adversity.

Farewell to an Icon: The Demise and Final Journey of the Knock Nevis


As time marched forward, the Knock Nevis reached the end of its illustrious career. The retirement process of such a monumental vessel was no small task. Scrapping procedures, while necessary, marked the end of an era. They dismantled the behemoth that had once ruled the seas piece by piece, leaving behind a bittersweet sentiment. Yet, its legacy endures, etched in the history books and the memories of those who marveled at its might.

Reflecting on the Remarkable Journey of the Knock Nevis

The Knock Nevis narrative showcases human ingenuity and tenacity throughout maritime history. The Seawise Giant’s rise from humble beginnings to the world’s largest supertanker illustrates our relentless pursuit of maritime dominance and promise. As we reflect on its incredible journey, we remember that ships are made of steel, but human aspiration and advancement weave their narrative.

The Knock Nevis, originally known as the Seawise Giant, is a supertanker celebrated as the world’s largest ship, setting records with its immense size and capacity.

The construction of the Knock Nevis, then Seawise Giant, took place in the early 1970s as part of the innovative TI Class Supertankers project.

The Knock Nevis stretched over 1,500 feet in length, making it longer than iconic landmarks like the Eiffel Tower, and its cargo capacity was a record-breaker in the maritime industry.

The colossal size posed stability challenges that were ingeniously overcome with innovative ballast systems. Navigating through narrow straits and ports also required exceptional skill.

In 2010, the ship was sold to a shipbreaking company. It was eventually dismantled and scrapped in Alang, India, marking the end of its remarkable journey as a global shipping gamechanger.

The Knock Nevis was truly colossal, measuring around 1,504 feet (458.45 meters) in length and had a width of 226.9 feet (69.1 meters). It had a draft of about 81 feet (24.6 meters) when fully loaded, making it challenging for the ship to navigate in shallower waters.

Operating a ship the size of the Knock Nevis presented numerous challenges. Its sheer size made it difficult to maneuver in tight waterways, limiting its accessibility to certain ports. Additionally, its immense weight required specialized infrastructure to load and unload cargo, which many ports lacked.

While the Knock Nevis held the record as the largest ship ever built, there have been other large vessels constructed since then, such as the Prelude FLNG (Floating Liquefied Natural Gas) facility. However, no other ship has matched the Knock Nevis’s sheer size and capacity as a supertanker.

The ship was scrapped in Alang, India, which is a well-known destination for dismantling large ships.

The materials and components from the ship’s scrapping were recycled and repurposed for various industrial applications.
