The continuous advancement of shipbuilding technology and techniques, coupled with the rapid development of the shipping industry, has led to a significant trend of ship size enlargement in recent years, especially in the development of large container ships.

Here are the largest commercial ships in various categories:

Largest Container Ship - HMM Algeciras (HMM, South Korea)

South Korean shipping giant Hyundai Merchant Marine (HMM) introduced the HMM Algeciras, a 23,964 TEU container ship, which is currently the world's largest container ship and the first vessel of the 24,000 TEU class. Built by Daewoo Shipbuilding & Marine Engineering (DSME) in South Korea, the ship was delivered earlier this year, with President Moon Jae-in attending the delivery ceremony.

The HMM Algeciras has a gross tonnage of 228,283 GT, a deadweight of 232,606 DWT, a length of 399.9 meters, a beam of 61 meters, a draft of 33.2 meters, and flies the Panamanian flag. It can carry 208 TEUs more than the previous Mediterranean Shipping Company's MSC Gulsun, setting a new world record for container capacity.

The deck area of this ship is larger than four football fields combined.

Largest Oil Tanker - TI-Class Supertanker (Euronav NV, Belgium)

The TI-Class supertankers, previously consisting of four vessels, were also constructed by DSME in South Korea and owned by the Greek company, Hellenic Shipping Group. In 2004, Euronav, a Belgian shipping company, and Overseas Shipholding Group (OSG) of the United States jointly purchased these vessels and renamed them as TI Africa, TI Asia, TI Europe, and TI Oceania.

The oil-carrying capacity of these vessels can support the oil consumption of France and the United Kingdom for a day.

Among them, the sister ships TI Africa and TI Asia have been converted into Floating Storage and Offloading (FSO) units. The TI-Class supertankers have a length of 380 meters, a beam of 68 meters, a total tonnage of 234,006 GT, and a deadweight of 441,585 DWT.

Largest Bulk Carrier - Valemax Ore Carrier (Vale, Brazil)

Valemax is a fleet of large ore carriers owned or leased by Vale, the world's largest iron ore producer and exporter. The plan includes the construction of 68 Valemax vessels, with the first vessel, Vale Brasil, commencing operations in May 2011. The dimensions and tonnage vary among the vessels. For example, the Vale Brasil has a length of 362 meters, a beam of 65 meters, a draft of 23 meters, and a fully loaded displacement of 402,300 tons.

Largest Cruise Ship - Symphony of the Seas (Royal Caribbean)

Symphony of the Seas, an Oasis 3-class cruise ship operated by Royal Caribbean International, is one of only two ships of its class in the world, alongside Harmony of the Seas, which was launched in 2016.

Symphony of the Seas measures 362 meters in length, 46 meters in width, surpassing its sister ship, Harmony of the Seas, with a gross tonnage of 230,000 GT (compared to Harmony of the Seas' 226,963 GT). It also features 28 more luxury suites than Harmony of the Seas.

These ships are approximately five times the size of the Titanic.

Largest Chemical Tanker - Bow Pioneer (Odfjell, Norway)

The chemical tanker Bow Pioneer was constructed at DSME in South Korea in June 2013. It has a length of 227.9 meters, a beam of 37 meters, a displacement of 98,802 tons, a total tonnage of 45,452 GT, and a deadweight of 81,305 DWT.

The Q-Max LNG carrier measures 345 meters in length, 53.8 meters in width, 34.7 meters in height, and has a draft of 12 meters. Its cargo capacity is 266,000 cubic meters, equivalent to 161,994,000 cubic meters of natural gas.
