12 Biggest Ships In The World

The shipping sector is sustained by a modern fleet of vessels belonging to different segments. Some ships carry general cargo, while others are specialised bulkers or ice-breaking ships made to ply the harshest shipping routes. A Few vessels, like tug boats, handle offshore projects, while cruise ships are built for leisure activities. 

In this article, we bring you the crowning vessel of each type, a leader of maritime innovation and design in its segment. Let us have a look at the 12 biggest ships in the world. 

1. MSC Irina- World’s Biggest Container Ship

MSC Irina is the biggest container ship in the world. It was ordered by MSC and constructed by Chinese Jiangsu Yangzi Xinfu Shipbuilding Co. 

It measures 399.9 m lengthwise and 61.3 m breadthwise, making it a true mammoth of the seas. Work began on the vessel in 2021, and dock assembly started in June 2022. She underwent sea trials in 2023 and was sent to Zhejiang Zhoushan Shipyard for final work as it was set for delivery in March.

It is sailing under the Liberian Flag and can carry over 24,300 standard 20-foot shipping containers. Irina is also endowed with several energy saving technologies and smart infrastructure like its small and bulbous bow, large-diameter propellors, an air lubrication system that decreases drag on the hull and also shaft generators for producing additional power.

These features help the container ship reduce energy consumption by 3-4 per cent compared to other container ships, cutting carbon emissions as well.

2. Icon of the Seas- Biggest Cruise Ship

Royal Caribbean’s Icon of the Seas is the largest cruise ship in the world, with a 248,663 gross tonnage. She is ready to enter service on 27th January 2024 out of the Miami Port in the U.S.

5. MS Turanor PlanetSolar- the largest solar-powered vessel

The popularity of solar-powered vessels in the maritime domain is credited to Swiss engineer Raphael Domjan who harboured a dream of designing such a vessel for a long time. However, his vision was realised only in the late 2000s when he garnered supporters to make it a reality. 

PlanetSolar took over a year to build and is 31 m long, 15 m broad, and around 6 m high, with a 1.5 m draft. It has a yacht-like design to offer comfort to its guests. 38,000 solar voltaic cells are spread over 5000 sq ft of its roof area. These cells absorb solar energy and store it in the 12 lithium-ion batteries in storage boxes.
