Tag: Shipping container facts

Shipping containers have affected our daily lives for many years, but what do you know about them? This article will help you out with some facts about shipping containers. Shipping containers carry a large percentage of the goods that impact our daily lives, and many people work with them (both directly and indirectly) in business. Since many people don’t think about containers regularly, we thought you might like to hear a few facts about shipping containers.

The Inventors of Shipping Containers

The inventor of the shipping container was Keith Tantlinger (1919-2011) (chief engineer at Brown Industries). In 1949 he designed the first modern shipping container, a 30ft Aluminium box that could be stacked 2 high on barges operating between Seattle and Alaska. Everybody was interested in this concept but unfortunately, nobody wanted to spend the money to get this idea off the ground. Source: The Box by Marc Levinson

Malcolm McLean (1913-2001) a very well respected Truck magnate since March 1934. McLean enlisted Tantlinger’s help to get advice on the shipping container idea. There was much discussion in working out what size container could be loaded in a hold of a ship, to get the maximum amount of cargo shipped most economically. In the 1950s McLean adapted the long-used transportation formula whose birth dates back to the early twentieth century.

The metal shipping container (intermodal container), that we know today, replaced the old-style “break bulk” method of goods handling.  Containerisation was born. McClean understood that reducing the cost of shipping goods required not just a metal box but an entirely new way of handling freight.

This meant that every part of the shipping system had to change-that included: ports, ships, cranes, storage facilities, trucks, trains and the operations of the shippers themselves. He was years ahead of his time. Source: The Box by Marc Levinson

Standardised sizes and big numbers

The standard container sizes are 20ft long or 40ft long. Although the 20ft units are referred to as 20ft long, the actual size is 19ft 10.5in long and the 40ft is 40ft long! The standard widths are 8ft, and the heights can be either 8ft 6in or 9ft 6in. The 9ft 6in high units are known as Hi cubes.

In 2012, over 20 million shipping containers in the world, and five or six million of them are shipping around the world on vessels, trucks, and trains. In total, they make approximately 200 million trips a year.

It’s estimated that there are 10,000 shipping containers lost at sea (including catastrophic events) every year. That’s almost 192 containers every day! Source: Singularity Hub.  Lost containers can be damaged by waves and sink (a 20ft can take up to 57 days, and a 40ft will take three times as long, to sink). The ones that don’t sink, often float just below the surface, which can cause a lot of damage to other sailing vessels.

Where are shipping containers made?

Approximately 97% of all shipping containers are manufactured in China. This is because the Chinese labour rate is lower than many other countries and that much of the world’s products are produced in China. Producing the container close to the shipment is far easier than re-posting containers worldwide. China manufactures approx. 5.8 million TEU (20ft equivalent) per annum. Source: Wikipedia

Container Ships around the world

Shanghai, China, was the busiest container port in the world in 2018. 42 million (TEU=equivalent to a 20ft container) containers passed through the port in 2018. Source: World Shipping council.

The Port of Felixstowe handled 3.85 million 20ft equivalent containers during 2018. Felixstowe handles the largest containerised traffic in the UK and handles 37% of the UK’s container units. Source: UK Department of Trade

According to the International Chamber of Shipping, there are more than 50,000 merchant ships operating in the oceans in 2019. The ‘OOCL Hong Kong’ was recorded as the largest cargo ship in the world in 2019. The ‘OOCL Hong Kong’ is owned by OOCL and is a length of 400 meters long by 58.8 meters wide by 32.5 meters in depth and holds the equivalent of 21,413 TEU (TEU=20ft equivalent). The OOCL Hong Kong visited Felixstowe in June 2017.

All commercially used shipping containers have a serial number which is made up of a 4 letter prefix (nearly always ending with a U and a seven-digit number [XXX-U-123456-1]. The first three letters signify the owner, and the next letter is the category of the container (U = unit freight container), followed by a six-digit serial number and finally a check digit. There is a mathematical formula that works out the check digit (final number).

Shipping containers can last over 25 years! Provided they are taken care of with regular paint and maintenance. See our Container care page.

A standard 20′ shipping container can hold 1,170 cubic feet and the max gross weight is 30T with a tare weight of 2.2T. A 40′ high cube contains 2,700 cubic feet and the max gross weight is 32.5T with a tare weight of 3.8T.

Liner ships transport approximately 60 per cent of the value of seaborne trade or more than US $4 trillion worth of goods annually. Source: World Shipping Council. It still makes financial sense to transport goods in high volume via sea/ocean.

All shipping containers have a CSC plate affixed, which acts as a passport for a container. HSE have more information

In 2020/21 there became a Worldwide shortage due to the pandemic first and then the massive knock-on effect. Please read our blog post here for more information.
