Global Supply Chain News: New Standard for Largest Container Ships, as Danish Company Pursues a Radical New Ship Design
New CSCL Ship Holds 19,000 TEU; Meet a New Ocean Container Hybrid; The Role of Sulfur Emissions

Maersk set the standard for the world's largest container ship by TEU capacity when its first "Triple E" vessel set sail from as Asia to Europe in 2013. The new generation of Maersk ships can hold a little over 18,000 TEU, and Maersk ordered some 20 of them in total from South Korea's Daewoo Shipbuilding - the first of its container ships that Maersk did not construct itself.
But the Triple E's title as largest ship on the seas didn't last long, as in December the new CSCL Globe from Hong Kong-based China Shipping Container Lines - capable of holding 19,000 TEU - set sail, arriving in the UK port at Suffolk this week. The ship is 400 meters long, and is said to have the capacity to move 300 million tablet computers. If the containers it can hold were laid end to end, they would stretch on for an incredible 72 miles.

But the CSCML Globe itself will hold the top spot for an even shorter period than the Triple E did. Soon to set sail in its first voyage is the MSC Oscar, which is capable of carrying about 120 more containers than the new CSCL ship.
Where will it end? Industry experts say there are designs on the table for ships capable of carrying perhaps 22,000 TEU.
The driver behind these ever larger megaships is simply economics. The operating and fuel costs per container are much less for the larger ships than for their smaller predecessors, though it was just a few years ago that a 13,000 TEU vessel was first being called a "megaship." The larger ships generally also release less CO2 per container than the smaller vessels.
Of course, those economics depend on being able to run the ships somewhere close to capacity, something Maersk struggled with at least early on. The need for that utilization is a significant factor behind the rise in ocean container shipping consortia, where capacity is pooled across carriers, most notably the proposed P3 alliance between the three largest carriers: Maersk, Switzerland's Mediterranean Shipping Co. and France's CMA CGM.
After having received regulatory approval from US and Euro officials, China shot the plan down in 2014, saying it would reduce competition in the sector. The idea was replaced by a 2M vessel sharing agreement between just Maersk and MSC, which was far less ambitious in its design in addition to involving just two carriers.
New Age Container Ship Design Gaining Interest
While most container lines and ship builders have been focused on simply larger and larger ships, there is news in recent weeks that there is growing interest in a radical new container ship design from a company called Lade AS that amazingly uses the curved hull of the ship as a form of giant sail.
The ship is called the "Vindskip," with the revolutionary design turning the whole vessel into a wind-assisted airfoil.
The ship is a like a giant Prius of the seas, with a hybrid design that combines a natural gas engine with the wind power. Lade says the ship could achieve fuel savings of 60% and reduce carbon emissions by 80%.
Designer Terje Lade says the new ship would operate more like an airplane than a sail boat.
"In the era of Christopher Columbus, for example, he would have used what became known as trade winds but his ship was quite different from the Vindskip because he would have been sailing with the wind - he couldn't sail into the wind," Lade says.

Lade says software being developed by Germany's Fraunhofer Center for Maritime Logistics and Services will calculates the optimal sailing route based on the weather and prevailing winds.
