Top-10 Largest Ships in the World by 2025, Check the List

Across the world’s expansive oceans, ships—remarkable feats of technology—navigate the waters, moving goods and passengers between continents. As we enter 2025, these enormous vessels have achieved record-breaking sizes and capacities. This article delves into the top 10 largest ships globally, highlighting the engineering achievements and maritime advancements that shape today’s maritime industry.

World’s Biggest Ship 2025

As of 2025, the Seawise Giant is recognized as the largest ship in the world, holding records for its length, weight, and cargo capacity. First built in 1979 as the Happy Giant oil tanker, it measured 458 meters long. Later, in 1988–1989, it underwent a major expansion, making it even larger. The Seawise Giant stands as a true marvel of engineering and remains a legendary name in the history of global shipping.

Key Facts About Seawise Giant, the World’s Largest Ship 2025

Here are some of the key points related to the Seawise Giant, the largest ship of the world:

• The Seawise Giant, world’s largest ship in 2025, underwent jumboization by cutting it in half and inserting a 5-meter block amidships.
• This process expanded its length to an astonishing 458.45 meters, making it the longest moving man-made object in history.
• As a very large crude carrier (VLCC), it boasted a record deadweight tonnage of 564,763 metric tons, capable of transporting over 4.5 million barrels of oil in a single voyage.
• The colossal ship required a crew of over 60 personnel for safe operation.
• Despite its remarkable career spanning three decades, the Seawise Giant was sold for scrap in 2009 due to escalating operational costs.

Largest Ship of the World – Historical Significance

Originally ordered in 1974 as an unnamed Ultra Large Crude Carrier (ULCC) with a 418,611-ton capacity, the Seawise Giant faced delays in naming due to disputes between the Greek owner and Japanese builder. Hong Kong businessman C.Y. Tung acquired it, leading to its transformation into the largest ship globally through jumboization, adding 146,000 tons. Renamed Seawise Giant, it began operations in 1981 as the longest and largest ship ever built, measuring 458 meters with a deadweight capacity of 564,763 tons. Damaged in the 1988 Iran-Iraq war, it underwent repairs, changed ownership multiple times, and was eventually scrapped in 2010.

Top-10 Largest Ships in the World as of 2025

As of 2025, Seawise Giant, constructed in 1979 stands as the largest ship in the world, with the total length of 458.46, followed by Batillus Class, Esso Pacific, and Valemax.

Here is the list of top-10 largest ships in the world:

Biggest Ship in the World – Seawise Giant

Length: 458.46

Type: Oil Tanker

Built in: 1979

The Seawise Giant, a colossal oil tanker, initially constructed in 1979 as an unnamed vessel, achieved its status as the world’s largest ship through ‘jumboization’ in 1981. This process, involving the addition of a new mid-section, propelled its overall length to an astounding 458 meters and increased its capacity to a record-breaking 564,763 deadweight tons (DWT). Notably, the Seawise Giant holds the title as the largest ship ever built, surpassing all others in overall length, deadweight tonnage, and gross tonnage.

Second Largest Ship of the World – Batillus Class

Length: 414.22

Type: Oil tanker

Built in: 1976-78

The Batillus class, comprising four oil tankers built from 1976 to 1978, stands as the second-largest ships globally. Originally designed with a capacity exceeding 550,000 deadweight tons (DWT) each, these ultra-large crude carriers were considered the largest and longest vessels at the time of construction. Their record held until the conversion of the Seawise Giant, marking a significant era in maritime history.

World’s Third Largest Ship – Esso Atlantic/Esso Pacific

Length: 406.57

Type: Oil tanker

Built in: 1977

The Esso Atlantic and Esso Pacific, twin oil tankers introduced in 1977, hold the distinction as the third-largest ships in the world. These identical sister vessels boasted a remarkable capacity exceeding 516,000 deadweight tons (DWT) each. Notably, they reigned as the longest ships afloat until the arrival of the Batillus class in the late 1970s, representing a pivotal period in maritime engineering and capacity.
