Biggest ship, nope nope nope.

A lot of misinformed malarkey in the press this week about the world’s  biggest cargo ship. Impressive figures and no mistake but it’s referring to the world’s biggest container ship. There are much much bigger maritime behmoths out there, indeedy so.

The following childlike ‘gush gosh’ facts from the tinterwebby.

The world’s biggest cargo ship has docked in Britain for the first time.

The Globe was built in South Korea and has arrived on its first trip.

It measures 400m long, 56m wide and 73m tall. So how can a ship so big work?

It can carry nearly 20,000 containers – the same as 14,500 buses – so how can it float?

Displacement

It’s all down to the ship’s massive size, and something called displacement.

 

For a ship to float, it has to push its weight in water downwards – or displace it.

Once it’s pushed down by the ship, this water pushes back upwards – and floats the ship.

So the bigger the ship – the more water it pushes down.

Graphic

If you laid every cargo container the ship can carry end to end, they’d stretch for 72 miles.

It’s also important that the heavy cargo crates are put at the bottom of the ship, and the lighter ones at the top. This stops the ship swaying when it’s at sea.

The BBC’s Richard Westcott explains how the Globe is loaded

The engine

So once a ship of that size is floating – how does it move?

It needs a big engine. And the Globe does not disappoint.

According to the company that made its diesel engine, it’s the biggest ever.

Globe engine

It’s over 17m tall and can generate the power of 38,000 powerful vacuum cleaners! (wtf does that mean?? Ed.)

How big can ships get? (Ever so ever so ever so big??)

With engines and ships so large – just how big can they get in the future?

The Globe will only have been the largest on the planet for a total 53 days.

MSC Oscar

MSC Oscar – soon to be the largest cargo ship in the world

MSC Oscar will overtake it when it first sets sail at the end of this month. It’ll be able to carry about 5% more than the Globe.

Bigger ships are appealing to transport companies because they can move more cargo per trip – saving money on fuel.

There are downsides though to larger ships – those big enough to carry 18,000 containers or more are too big to stop in many ports around the world.

In fact they can only sail between Asia and Europe, with ports in countries like the USA being too small to hold them.

The Globe even takes up two giant parking spaces as it’s docked in Felixstowe.

From g Captain

The world’s largest ship, the Pieter Schelte, arrived in Rotterdam Thursday after an approximately 7 week voyage from the DSME shipyard in South Korea, at least 4 years under construction, and decades of planning.

The giant catamaran-like ship has been moved to Rotterdam where the final phases of construction will take place. Plans call for the vessel to be moved to Alexiahaven to a specially-designed and dredged berth known as Maasvlakte 2, where the 65-metre long beams of the topside lift system will be installed.

At 382 meters (1,253 feet) long by 124 meters wide (407 feet), the vessel is arguably one of the biggest ships ever constructed. With help from a slot at the bow and a 48,000 tonne lifting capacity, the Pieter Schelte will be used to install and remove decommissioned topsides and jackets of large offshore oil and gas platforms in the North Sea with a single lift. The vessel is also equipped for laying large pipelines with a capacity that will also make her the largest pipelay vessel.

The Pieter Schelte was commissioned by Swiss company Allseas, which specializes in offshore pipeline installation and subsea construction, and reportedly cost close to $3 billion to construct.

The vessel has been under construction at the Daewoo Shipbuilding and Marine Engineering shipyard in Okpo since 2010 (although early construction even began as early as 2007), and the concept dates back to 1987 when it was first designed by Allseas founder and chief executive Edward Heerema.

Pieter Schelte departed DSME on November 17, 2014 with the assistance of tugs. On its journey to Rotterdam, the ship made stops at Singapore and then Cape Town as it passed the Cape of Good Hope.

Offshore operations are expected to commence in the summer of 2015, according to Allseas. Allseas is also planning a second, larger ship with a lifting capacity up to 50% greater capacity.
