While some cruise ships do make this list it is the oil tankers and container ships of this world that make up most of it. When it comes to length of some ships it is not necessarily what you see above the water that is the longest part, but be it the top, or the bottom, these are the longest ships in the world and some of them are mind-blowing lengths…

The Top 10 Longest Ships in the World Still In Service

10 – INS Vikramaditya – Type: Aircraft carrier – Length: 283.5 m (930 ft)

Its name means ‘brave as the sun’ and it is a modified Kiev-class aircraft carrier built for the Indian Navy in 2013 and still in service today.

9 – Admiral Kuznetsov class – Type: Aircraft carrier – Length: 304.5 m (999 ft)

Said to be the last aircraft carrier commissioned by the Soviet Navy it was a massive advancement over their previous ships and is still considered to be the best Aircraft carrier still in service today.

8 – Paul R. Tregurtha – Type: Lake freighter – Length: 309 m (1,014 ft)

When it comes to the class of ships, this is more a boat than a ship, but we won’t be picking holes in that discussion today. This ‘ship’ is the worlds largest and longest ‘laker’ and holds up to 14,497 tonnes!

7 – Q-Max – Type: LNG carrier – Length: 345 m (1,132 ft)

Officially the world largest LNG (liquefied natural gas) carrier in the world is can hold 135,000 cubic meters of gas and it’s a small collection of 14 ships (not all of them still active). But again they are only counted as 1 ship for this list.

6 – Queen Mary 2 – Type: Ocean liner – Length: 345 m (1,132 ft)

The worlds longest ocean liner was built for the British Cunard Line since Queen Elizabeth 2nd. For those who don’t know the difference between an Ocean Liner and a Cruise Ship is often the amount of onboard entertainment and facilities. An Ocean Liner is designed to take people from point A to point B so doesn’t have that much on-ship entertainment. But a Cruise ship has loads because it is designed to be the point of destination rather than a form of transport.

5 – Oasis class – Type: Cruise ship – Length: 360–362 m (1,181–1,188 ft)

This collection of 5 ships are the worlds longest (still active) cruise ships and carry up to 6,296 passengers when fully booked. Set over 16 (passenger) decks there is a shopping centre, several cinema screens, play screens and even several bowling lanes to name just a small selection of the onboard entertainment.

4 – Valemax – Type: Bulk carrier – Length: 360–362 m (1,181–1,188 ft)

This is a vast collection of 67 ships (not all of them still active) owned or chartered by the Brazilian mining company Vale S.A. While they are designed to carry all sorts of things they mostly carry iron ore from Brazil to European and Asian ports. Once again, I am only counting them as 1.

3 – TI class – Type: Oil Tankers – Length: 380 m (1,247 ft)

This set of 4 ships (I am only counting them as 1) are the worlds biggest oil tankers. While they are not the biggest ever built they are the longest that are still active today.

2 – Pioneering Spirit – Type: Crane vessel – Length: 382 m (1,253 ft)

Offical the worlds largest (still active) construction vessel it was designed for a single job in mind, but yet it is still active today. Built in South Korea by the Daewoo Shipbuilding & Marine Engineering it is built for installation and removal of large oil and gas platforms.

1 – Barzan – Type: Container ship – Length: 400 m (1,312 ft)

This ship is not just one but is in fact 6 ships all the same length and all built for the UASC (United Arab Shipping Company). While some of them have since been scrapped, this ultra-large container ship is still king of the seas (when it comes to length anyway).
